ContentsThis issue of Helmet covers a very interesting

spectrum of several EHS stories that are

either meant to spread awareness or to share

information such that the good practice is spread

across for the larger benefit of the organisation.

A new section interviewing project managers to

understand their perspective on EHS has been

added in the first few pages.

A simple and ingenious way of making light

bulbs out of empty PET bottles makes for a very

interesting read. With the county facing several

cyclones in the monsoon period, an article on

project level cyclone preparedness can be very

informative to many. This apart, there are several

other articles and EHS events that have been

covered in this issue. Hope that these articles

make for an interesting and good read.

Happy reading

Financial year 2013-14 started with a very

positive note for B&F IC, with regard to the EHS

Performance; first five months were extremely

good, compared to the same period the year before;

however, our spirits were short-lived and within a few

days during the month of Aug/ Sep, there were many

incidents, which set us introspecting ourselves in a

more systematic manner!

Hoist and replacing it with new generation multi-

purpose hoists’ and so on.

However, unless all these improvements are captured

in the management system, in the form of checklists,

inspection guidelines, purchase/ hire procedures etc.,

it will not be a consistent effort. Now that’s what

has happened exactly – for instance, the ‘delay start

Journeying towards a culture of zero tolerance on at-risk behaviour

The introspection took us through a performance

transformation curve, which every organization will pass

through, during the safety management journey.

If you take a closer look at the above figure, incident

rates will come down over a period of time as the

organization goes through technical improvements.

This is done by introducing new technology, equipment

and process changes. We could quote here many

examples within any of our ICs; however, with specific

reference to B&F, we have introduced innumerable

initiatives over the past few years, such as ‘phasing

out old generation hydra’, ‘introducing delay start

mechanism in the vehicles’, ‘phasing out the Builders

mechanism’ was introduced in ALL the construction

equipment in B&F IC about an year back and today

there are many hired equipment (including some of

our own equipment) that are operational in our project

sites without this safety device; basic reason for this

being, such initiatives have NOT been captured in the

inspection checklist or in the purchase/ hire policy (and

procedures).

Assuming that all such initiatives (technology

improvements) are captured in the HSE management

systems, will there be a guarantee that incident

rates will further reduce? Yes, provided we ensure

that the employees are self-motivated (intrinsically

Buildings & Factories 3HELMET July - Sep 2013

Page 4: Environment Safety Health HelmetJuly - Sep 2013 • Volume - 3 ...

motivated), because they are the ones who have to be

instrumental in implementing the systems, monitoring

the compliance and taking action on the deviations (if

any) from the requirements of the system. ‘Cultural

improvement’ is therefore the key to have intrinsically

motivated employees. Cultural improvement through

a process of establishing a ‘no-blame approach’,

ensuring upward communication from all levels of

employees without fear of reprisal, achieving high

level of trust among employees through positive

communication/ consultation with regard to EHS

roles/ responsibilities and lastly having a transparent

performance measurement system, which is linked to

the appraisal.

Assuming that we reach the ultimate stage of having

intrinsically motivated employees by establishing a

positive EHS culture within the organization, the

challenge will now shift towards maintaining this culture

through a process of periodic cultural diagnosis and

having a resilient workforce through behaviour based

safety initiatives.

All our initiatives during the past few months are

consciously designed to take our organization directly

to the third and fourth level of making our employees

‘intrinsically motivated’ to work safely and to sustain it

for a longer duration!

For example, we are encouraging all workmen to

inform the EHS team at site or to their supervisors or to

us directly (through the Toll-Free number) their safety

concerns/ their suggestions. Whenever we receive

any such information from workmen, their identity is

kept confidential while seeking corrective action from

the respective site and the concerned person is given

feedback about the action taken!

We have provided ‘safety improvement slip’ booklet to

all the supervisors/ engineers/ managers and they are

encouraged to issue the slip to any employee (even to

their seniors), if they are found to be working in an

unsafe manner. In fact, all the safety incentive schemes

that are operational at site are NOW linked to these

initiatives. This is expected to bring about a positive

culture throughout the organization.

We are giving confidence to all levels of employees that

they will not be penalized/ punished after an accident,

unless there are glaring omissions on the part of any

employee. However, we are giving a very strong message

that based on their score in the proactive EHS performance

monitoring system, (which is very transparent in nature)

they will certainly be held accountable.

Another significant drive we are currently embarked

upon is to make every frontline engineer to report

what they did/failed to do, on a daily basis, as part

of their daily progress report (DPR). We strongly

believe in integrating the safety requirements

in the existing management system procedures

(operational procedures) rather than creating

separate procedures for EHS, which may potentially

complicate matters. This is the reason why, the

frontline engineers are being asked to write (in the

DPR) what they did for enforcing safety in their

respective place of work.

We have also launched another very interesting

and practical method of influencing the minds of

the frontline engineers/ supervisors/ foremen, who

are directly involved in giving job instructions to the

workmen and are authorizing the workmen to work

in a certain manner and in certain conditions. The

work instructions currently revolve around ‘what’

needs to be done and very rarely talks about ‘how’

the work is to be done! This method (called as ‘safe-

to-start-work card’ or ‘STARRT’ card) will condition

their mind to look into the hazards of the activity

(with specific reference to the environment in which

the activity is being taken up on that day) and the

actual controls that are currently in place while they

‘authorize’ the work to be started by the workmen

in the existing condition. This also gives the staff

an opportunity to tell the workmen ‘why’ the job

has to be carried out in a particular manner. When

the question ‘why’ is addressed, the likelihood of

compliance will be very high and the behaviour

modification we achieve through such initiatives are

likely to last much longer.

We would like to thank all levels of employees who

are very cooperative and obliging to all our initiatives,

without which we will not be able to reach our ultimate

goal of “establishing a culture of zero tolerance on at-

risk behaviour”

Will update more in the next issue and until then,

with lots of wishes for the forthcoming festive

seasons!

Flashback Arrestors

A flash back arrestor is a safety device that shuts off gas flow in event of flash back. Flashback can travel back through the hose to your gas

source, if a flash back arrestors is not in line. A flash back arrestor shuts off gas flow and extinguishes the flame before it can reach your gas source. Several factors can cause flash back, including failing to purge line properly, using improper pressure, leaks in your gas management system and improper system operation. It is recommend that using a flash back arrestor on your fuel line as well as the oxygen line.

Flashback

Flashback is the condition of the flame propagating down the hoses of an oxy-fuel welding and cutting system. The flame burns backwards into the hose, causing a popping or squealing noise. It can cause an explosion in the hose with the potential to injure or kill person who handles it. Using a lower pressure than recommended can cause a flashback.

Causes of Flash Back

1. Wrong gas sequence during start-up

2. Insufficient Purging to clean the hoses prior to start

3. Blocked, worn, undersized or overheated blowpipe tip.

4. Blocked section in the blowpipe, cutting attachment or heating attachment.

5. Hose run over by a vehicle during Cutting

6. Wrong gas pressures. Where practicable, gauges should be within sight of the operator

7. Gas hoses of excessive length causing pressure loss.

8. Slag blocking tip.

9. Flame held too close to work surface

10. Hot metal falling on and burning through hose

11. Pressure loss or insufficient supply in either gas hose.

How Flash Back Arrestors work

a) By reducing the velocity of the flame, even lower than the minimum flame velocity of the fuel gas

b) Stops the flame propagation into or through a pipe. By placing a flame arrestor at the end of the flammable mixture pipe feeding a flare or burner, flame can be prevented from moving into the pipe regardless of the mixture velocity.

c) By passing a potentially flammable mixture through a water chamber or some sort of heat

sink. This dissipates the heat and quenches the flashback.

d) By blocking the fuel gas path, with a suitable thermal fuse plug, casing the flashback to die out.

e) By blocking the flow of fuel gas in the opposite direction by acting like a non-return valve.

Things you can do to help prevent flashbacks, fires and explosions:

1. If using acetylene, keep the pressure below 1.5 Bar

2. Purge your hoses before lighting the torch.

3. Never light your torch with a mixture of fuel and oxygen. After purging the lines, light the torch with only the fuel gas valve open.

4. Check valves should be installed on both torch inlets and operating properly. Check valves can stop the reverse flow of gases, but will not prevent flashbacks.

5. To prevent flashbacks, flashback arrestors must be installed on the outlets of both regulators,and/or torch inlets.

LPG Cylinder SafetyUnderstanding the Material Safety Data Sheet for LIQUEFIED PETROLEUM GAS

What is Material Safety Data Sheet?

Material Safety Data Sheet (MSDS) also known as Product Safety Data Sheet (PSDS) is an important document that contains information on potential hazards and instructions on how to work safely. It is an essential starting point for the development of a complete Environment Health and Safety Program. It also contains the information on the use, storage, handling and emergency procedures of the material. This sheet includes information such as physical data (melting point, boiling point, flash point, ignition point etc.), Chemical data, Toxicity, health effects, first aid, reactivity, storage, disposal and other information.

When would you use an MSDS?

Always be familiar with the hazards of a product BEFORE you start using it. You should look at the MSDS and match the chemical on your container to work safely with it.

MSDS educates people on how to safely handle the controlled products.

Here we are going to learn about the MSDS of LPG. Before entering into the MSDS of a product we need to study the basic information about the product.

LPG in atmosphere

LPG at atmospheric pressure and temperature is a gas which is 1.5 to 2.0 times heavier than air. Since LPG vapor is heavier than air, it would normally settle down at ground level/ low lying places, and accumulate in depressions.

Is LPG Odorless& Colorless?

Yes LPG is odorless and colorless in its natural form. But to detect

the gas leak a stenching agent called Ethyl Mercaptan is added. LPG is colorless both in liquid and vapor phase. During leakage the vaporization of liquid cools the atmosphere and condenses the water vapor contained in them to form a whitish fog which may make it possible to see an escape of LPG.

An MSDS is NOT a document intended to represent all the

information needed for safe use of a product. It cannot foresee all

possible types of worker exposure

Toxic effects of LPG

LPG even though slightly toxic, is not poisonous in vapor phase, but can, however, suffocate when in large concentrations due to the fact that it displaces oxygen. In view of this, the vapors possess mild anesthetic properties.

Flammability Range of LPG

LPG has an explosive range of 1.8% to 9.5% volume of gas in air. This is considerably narrower than other common gaseous fuels. The auto-ignition temperature of LPG is around 410-580 deg. C and hence it will not ignite on its own at normal temperature.

Flash Point and Fire Point of LPG

The flash point is that minimum temperature at which there is enough evaporated fuel in air to start combustion. The lower the flash point, the easier it is to ignite the material. Flash Point of LPG is < - 60ºC/ < - 76ºF. Fire Point is the temperature at which it will continue to burn after ignition for at least 5 seconds. Fire Point of LPG is– 0.5 ºC / 31.1 ºF.

A spectacular example of the consequences of introducing a blast to a flammable limit atmosphere occurred in Chennai in May, 2013. A 45 year old woman went to light up the stove in kitchen around 6 am. There was a gas leak from the tube connecting the stove and LPG cylinder. The flammable limits of LPG are narrower, 1.8% to 9.5 % in air. Flash Point is < - 60ºC/ < - 76ºF. Boiling Point is– 0.5 ºC / 31.1 ºF. When the women lit up the stove, an undetermined blast occurred (light bulb, fire prone materials like oil, fire match etc.) thus ignited the mixture with terrible results.

Do you know the flash points for the chemicals you handle?

Do you know how they are stored?

At work? At home?

Learn the basic properties of the product before handling them!

Proper storage & understanding how dangerous chemicals can become if subjected to heat is just using good safety common sense.

“I chose to look the other way”a poem by Don Merrell

I Chose To Look The Other Way

I could have saved a life that day, But I chose to look the other way.

It wasn’t that I didn’t care; I had the time, and I was there.

But I didn’t want to seem a fool, Or argue over a safety rule.

I knew he’d done the job before; If I spoke up he might get sore.

The chances didn’t seem that bad; I’d done the same, he knew I had.

So I shook my head and walked by; He knew the risks as well as I.

He took the chance, I closed an eye; And with that act, I let him die. I could have saved a life that day, But I chose to look the other way.

Now every time I see his wife, I know I should have saved his life.

That guilt is something I must bear; But isn’t’ something you need to share.

If you see a risk that others take That puts their health or life at stake, The question asked or thing you say;

Could help them live another day.

If you see a risk and walk away, Then hope you never have to say, “I could have saved a life that day, But I chose to look the other way.”

Interview of a project manager on EHS

In view of the increasing readership for helmet magazine even from the other divisions of L&T, we thought it appropriate to introduce a section on how EHS is perceived by colleagues who are not directly under the gamut of the EHS department.

After much deliberation, the thought to hold an interactive session with a project manager originated. This consultation of people either for their feedback or consultation is also a part of the EHS Management system which we have accredited to and here’s hoping that this initiative would be a seed in transforming the EHS culture of the organization.

The first session started with one of the Chennai based projects where the team from Helmet magazine, Mr. Gabrial Fernandez. N from B&F EHS department and Mr. Gopi Kannan. S from Corporate Communications, met up with Mr. M. Gopinath, Project Manager, Prestige Belle vista Project, Chennai.

Here are the excerpts:

What amount of your time is spent on safety related activities?

Safety is something that is very close to my heart and also what I begin my daily activities with. Every day, the site activities start with a safety pledge that is mandatory for all the workmen and the staff. We strongly believe that through this initiative, every single person enters the work site with a strong EHS cultural orientation and awareness. I would say that on a daily basis, about 30 to 40 % of my time will be touching upon safety related aspects.

How do you divide the activities that are based on EHS?

The morning PEP talk will be entirely focussed on EHS apart from the morning ‘walk’ around the site which will have EHS as the primary area of focus. We monitor PPEs, platform safety, material handling housekeeping, etc., during such walks.

How do you demonstrate your commitment to EHS?

Any meeting in the project starts only with a safety pledge. Though the top management expects very good performance in terms of timely completion and quality, the project team puts safety as a priority that supersedes the expectations. So according to me, safety is not simply about wearing our PPEs but more about our consciousness and it should be in every gene of our body. According to me safety needs no cadre – meaning, anybody is empowered to stop an un-safe act. One need not be a senior person to do this.

I also believe in the “sama dana bheda danda” philosophy whereby, I first try to convince, then use reward, threat and finally punish if safety standards are not adhered to.

There have been instances when I find non-compliance, I will insist in not moving from that place until this is set right. Such firm exhibition of adherence to safety standards has helped me exhibit my personal commitment to EHS.

How is risk assessment being done in this project?

Let me explain this with an example, for a vertical staging, a person will be deputed to physically check each and every pin. This may be seen as a very time taking and elementary process, but it is needed to ensure the safety

of all. In this project, we do a lot of brainstorming to bring out possible risk situations and find solutions to the same as a team.

How often do you do a structured safety inspection?

Under the chairmanship of the project leader, we have formed a special EHS team that meets once every week. We have a system of intergroup or cross functional audit. Sometimes, I call for some special meetings randomly and every single person in this project assembles for a brief period and I ask them to come out with five points to enhance EHS culture and efficiency of operations.

I believe in the “sama dana bheda danda” philosophy

Page 11: Environment Safety Health HelmetJuly - Sep 2013 • Volume - 3 ...

11HELMET July - Sep 2013

How do you ensure that the inspection is an effective one?

I will first and foremost wear all my PPEs because I should be safe myself. We will talk up to mate level and in certain occasions, we talk also to the workmen level to make them understand the deviations found.

How do you communicate critical work activities relating to EHS to workmen?

In this project, we lay a great amount of importance for visually communicating the message. We provide the images of do’s and don’ts in an easy to understand manner so that it is easily followed. This is because people will interpret words in their own way. For instance, when you say ‘no gap in walkway’ you will have to support with an image to show how tight the structures have been fastened, this helps people understand and implement.

What percentage of annual accountability of yours has been accorded to safety and how do you think it can be measured?

About 25 % of value driver is allotted to safety. Firstly it can be measured by the safe man hours or non-reportable incidents apart from the nominations to safety awards. In an indirect manner it can also be measured by judging the safety culture that is prevalent in the team.

How do you measure the performance of your project and the subordinates with respect to safety?

The performance is analysed in the monthly review meetings and during the cross functional audits within the project. All the first aid cases are reviewed in a serious manner which is a sort of reactive monitoring system. In fact, right now there is no metric available for assessing the systems implemented by the subordinates when it comes to EHS. Of course, the recently introduced proactive EHS monitoring system meets the requirement of measuring the performance of subordinates.

When it comes to safety, the measure of performance is perceived in a negative manner. (for instance, “lost time injuries” etc.,) can there be a positive measure for EHS? If yes, what can it be?

In safety even one incident can make the result negative. But unfortunately there are very few metrics for safety performance. Proactive EHS monitoring system that has been implemented across the organisation recently has

now enabled us to measure our safety performance easily. It is a good sign of driving down the message of positive safety culture.

Your views on proactive monitoring system?

This system has been implemented in the site based on attributes and criteria. Metrics are getting implemented on housekeeping, improvement slips are given, suggestions from staff, safe-to-start card system is getting followed. This system, though seen as laborious at present, is an excellent way to create a positive work culture.

Are critical area safety audits being conducted at your site?

When audits are done internally, it seems ok, but when external teams do it there seems to be a variance sometimes. This according to me can be attributed to a matter of perception.

Safety cultural transformation should begin from whom?

It should be top driven but bottom implemented and things should not be forced rather should be implemented as a system.

If workmen adhere to EHS work culture without being monitored, is that a good safe culture? Is it the status with your project? If no, how do you plan to implement the same?

Absolutely, when workmen behave in such a manner, it exhibits a very positive EHS culture. It is not immediately possible because of the attrition rates of the workmen.

Any specific EHS responsibility you are personally accountable for?

I would say the health of workmen and environmental initiatives have to be driven down from the top. Apart from this, I also believe that developing a safety conscious team is my responsibility.

Did you get any direct communication on your roles and responsibilities on EHS from the top management?

With safety, there is no direct communication in a formal manner as it is the case with other directives such as quality and timely performance.

Have you communicated formally about the EHS responsibilities to your subordinates?

Yes, during monthly review meetings it is communicated and they are advised on how sequence following is

12 HELMET July - Sep 2013

important, work procedure, using right tools and getting safety approvals for critical areas are communicated.

What percentage of annual operating budget is spent on safety?

In this project, the actual budgeted amount is insufficient and there is a gap. However, safety is never compromised in my project site due to such operational issues. But it would be better if the EHS budgets are planned during the tendering stage itself. It will further enhance the safety performance of the project as a whole.

What is the distribution of expenses on this budget?

It is mostly used for PPEs, protection at site level and then spent for safety training programmes and safety events. Some of the budget also goes towards rewards for workmen on safety contests. There is a major challenge faced nowadays in the construction segment when it comes to budget for EHS. Since the attrition rate of workmen is very high, the costs on PPEs are significantly higher than originally budgeted for.

As a project manager, what according to you would be the costs associated with safety related incident based on the severity right from first aid cases to fatal?

There are many direct and indirect costs involved when an accident occurs. By the time a project gets back to normalcy, a considerable amount of costs would be involved. As for health issues, about twenty five thousand rupees is being earmarked on a monthly basis approximately including first –aid cases.

How many hours of formal safety training have you attended in the last two years?

There has not been any formal training on EHS. But have

been a part of Dupont training programme and training conducted by Mr. Jeet Bindra. I am also very keen on being a part of such EHS programmes, however owing to the pressing needs of project management, I even missed out on an excellent program on EHS leadership workshop.

What are the situations where established safety work procedures can be deviated due to the situations?

For instance, there is a percentage of deviation in the hire-vehicles of higher capacity which are in short supply in the market. Though we know that there is a problem, we also go by the severity of same based on the situation.

Sometimes there are times when I have to not be able to be a 100 per cent safety manger due to pressure on timely completion. During such occasions we do have a slight shift in priority but that is only very marginally.

Can you give one specific initiative that you have implemented / wish to implement?

I have a system by which a site engineer is made as a ‘safety engineer’ for a period of one month. Through this job rotation, many new areas come to light and the team building also gets stronger because there is empathy among team members.

Do you think a safety engineer is really required at a site?

A safety engineer is like a coach, whereas the site engineer is a performer. While a coach can only guide, he cannot perform. But when the performance is not up to the mark, the coach is penalised. So under ideal conditions, site engineers should learn to perform with just the guidance from the safety team.

International / National Standard

“Knowledge has to be improved, challenged, and increased constantly, or it vanishes.” By Peter Drucker

Hope the last issue on handling and storage of building materials would have given a basic idea and procedure for storing different building materials. Also bear in mind that implementing the information learnt is far more important than reading it.

Material handling always poses one of the severe hazards compared to other activities carried out at projects. Safety in material handling starts form size / structure / shape of the object / equipment to be handled, selection of crane and lifting gears, skilled manpower deployment, logistics, repetition of the handling, time, etc. Vigilant care is needed if crane or any other machinery is involved in the material handling process.

Excerpts from IS 13667 – part 1 general “Safety use of cranes – Code of practice” is covered in this issue to enhance your knowledge on Safe use of cranes during lifting operations.

This standard dealt various aspects of material handling such as Management and Planning of the lifting operation, Types and selection of cranes and persons, Signaling, Erection & dismantling, Legal legislations, Testing and examination, etc. in safe usage of cranes.

Since the details pertaining to the safe use of crane are enormous in this standard, we may cover only a few topics in this article. Definitions of certain terms, management and planning of the lifting operation shall be focused on in this issue. Other topics shall be covered subsequently in the forthcoming issues.

Definitions

Appointed Person

The person appointed by the management requiring the lifting operation to be undertaken who will be responsible for all aspects of lifting operation.

Competent Person

A person who is deemed to be competent and has such practical and theoretical knowledge and such experience of the crane and the equipment used in the lifting operation as is necessary to carry out the

function to which the term relates in each particular context.

Driver

The person who is operating the crane for the purpose of positioning loads.

Driver does not include any person who is operating a crane for erection of the crane itself.

Automatic Safe Load Indicator (ASLI) & Load Radius Indicator

Overloading is one of the most critical events to cause accidents. ASLI is fitted in all the cranes for the operator to visualize the load in case of overloading beyond the safe working load. The sample picture below shows the safe load and radius of a crane operation.

The ASLI automatically gives visual indication to the driver when the load being lifted or carried by the crane approaches the safe working load. It gives a continuous audible warning to the driver and other persons in the vicinity when the load being lifted or carried exceeds the safe working load. Under certain statutory regulations, the automatic safe load indicator should be of a type approved by the chief Inspector of Factories.

A device fitted on a crane that shows the radius of the hook and the corresponding safe working load.

14 HELMET July - Sep 2013

Radius

It is the horizontal distance between the point at which the centre of rotation of the crane meets the ground, and the vertical center line through the hook.

Management of Lifting Operation

Safe System of Work

A safe system of work must be established and followed for every lifting operation. Safe system of work helps ensure the safety of all personnel. This should also help prevent any inadvertent restoration of the power or movement of the crane.

This should include the planning of the operation, the provision, selection, maintenance and examination of the correct equipment and the provision of properly trained, competent personnel with adequate supervision.

The safe system of work should be clearly documented as relying on verbal instructions alone is not enough to ensure safety. The system should ensure effective communication between all parties concerned.

Appointed person and his duties

The management of the organization requiring the lifting operation should appoint a competent person with appropriate training and experience. This person is known as the appointed person. He will not undertake any other duties such as crane operation, slinger or siganaller.

Duties included are;

y Assessment of lifting operation for planning, selection of crane(s), lifting gear and equipment, instruction and supervision as is necessary for the task to be undertaken safely. This should include :

y Ensuring there is an effective procedure for reporting defects and incidents and adequate maintenance for Equipment

y Responsibility to organize the team involved in the lifting operation.

y Responsibility for control of the entire lifting operation.

The appointed person should be given the necessary authority for the performance of all these duties and in particular, authority to stop the operation whenever he considers that danger is likely to arise should the operation continue.

Planning of Lifting Operation

Planning is a crucial part in lifting operation and it shall be documented, but extent of detailed planning depends on the complexity of the operation

Radius of a hydraulic mobile crane

Effect of a swinging load on load radius

Note: Always lift loads gently and operate crane motions smoothly to avoid load swinging (A swinging load will increase the overturning moment of the cranes.) Use steady lines where necessary and where the load presents a wind catching area. Always travel with the load near to ground level so that load swinging can be controlled easily.

(However,in no case can planning be ignored). Every dismantling should be planned to ensure that it is carried out in a safe manner. The plan should never permit exceeding the safe working load of the crane or equipment.

Factors to be considered in planning:

y Nature of any obstructions and hazards to the load or crane during the operation

y Ground conditions (Investigation of ground conditions)

y Determination of load and characteristics (Including centre of gravity)

y Movement of load throughout the lifting operation

y Production of detailed plan of different elevation of the lifting operation at all critical phases from the initial siting of the crane to the final landing of the load

y Written statement of duties of each member of the team ensuring that all members of the team are aware of the statement

y If the crane(s) are called for l ifting operation, it has to be erected before commencing

and dismantled after completion of

works

y Relevant factors including space, suitability of

ground and access shall be ensured

y Lifting operations involving the simultaneous use

of more than one crane carry a higher risk factor

than those using only one crane. Additional care

should be taken in planning (planning multiple

lifting operation shall be given in next issue) such

activities.

¾ It is also essential that the drivers, slingers

and the person in charge are thoroughly

briefed with particular emphasis on the effect

that the operation of one crane has on the

other(s).

¾ Three dimensional scale models should be

considered a useful aid to the team briefing

for particularly complicated lifts.

Planning for the Permanently Installed Crane

Where a crane is installed to carry out a number of

operations or is installed as a permanent fixture, the

planning should be carried out prior to the selection

and installation of the crane. An account of the

continual lifting requirements and the loads that are

likely to be lifted should be taken. The operations

should be reviewed periodically to check that the size

and nature of the loads have not altered significantly

and that the crane and equipment are still suitable for

the duty required of them.

Minimum Planning

Lifting operations that involve no apparent difficulties

with access, erection and dismantling, obstructions,

hazards or other complications should only require

minimum planning. Following the selection of a

suitable crane and range of lifting gear and equipment

for the loads to be lifted, such operations may be

delegated to the team of slinger(s) and crane driver

following a brief on their task.

The selection of persons and their duties, signals

during material handling shall be covered in the

next issue….

It happened; it can happen; prevent it

What happened?

On a gloomy day in a construction project, shifting of form work equipment (Used for handling table forms) was in progress using a tower crane. While shifting the equipment from the extended (cantilevered loading) platform of first floor, it was swung at a height of around 10 m towards the extended platform in the second floor. When the equipment was lowered, suddenly the bottom portion of the equipment got detached from the top portion and fell to the ground.

During investigation, it was found that while lowering the equipment, the hydraulic piston in the equipment detached from the assembly, leaving the top portion with the tower crane hook.

What went wrong?

y Sling was attached to the top portion of the equipment whereas it was supposed to be connected in the hooks provided at the bottom portion. This is a clear case of improper method of slinging arrangement leading to separation of the equipment into two parts.

y Only one signal man was available at the unloading point; he was not familiar / competent enough in rigging practices.

y Lifting point was not clearly marked and working crew was engaged without any pre-task assignment discussion.

How to prevent it?

y Lifting /anchoring / hooking / slinging points shall be visibly marked on the equipment for easy identification.

y Pre-briefing should be done on the hazards and sequence of activity. In order to make this practice mandatory, STARRT card / ‘Safe-To-Start-Work Card’ system has been introduced and all sites have started implementing this in all earnest.

y Skill evaluation must be done for all signal men and riggers prior to deployment.

y At least two signal men per tower crane shall be engaged at loading and unloading points; it may be increased if the tower crane is to carry out works in more than 2 structures.

Failures related to mechanical handling normally occur due to various reasons, such as overloading, sling failure etc. In this case, the root cause of the failure is due to the fact that the configuration of the load was not considered while deciding the slinging point. As a customary and conventional object, the slings were attached to the top of the load.

Many such objects could be handled in our project sites and hence this incident is being shared with the readers of “The Helmet”, with a request to identify such critical equipment/ machinery that are likely to be handled and to take appropriate precautions.

Making mistakes is not a crime. Not learning from them, repeating them is criminal.

Road Safety – A Picture Story

Keep your distanceYou can’t crash into space! The more space you keep around you, the less risk of a collision. Be on your lane.

More haste less speedIn busy congested conditions or in built-up areas give yourself time. There’s no need to speed and you won’t get there any quicker.

Look ahead and anticipateDon’t just look at the vehicle in front and in your mirror to observe what is going on immediately around. Anticipate what is happening ahead of you by looking at the furthest point along the road as well as observing the behaviours of your fellow road users.

Think F.L.O.W.E.R.SEnsuring that your vehicle is serviced regularly (in line with the manufacturers’ recommendations) will help avoid breakdowns and accidents caused by vehicle faults. To ensure safety for both yourself and those around you and to keep your vehicle running smoothly,

Remember FLOWERS

Fuel : Play safe and stay topped up.

Lights : Regularly check main beams, indicators, fog lights, sidelights and brake lights.

Oil : Over-filling or under-filling the oil risks engine damage.

Water : Keep the screen wash reservoir full and use plenty of additives in winter, BEFORE it freezes up (in cold weather conditions).

Electrics : Check battery, wiper blades, electric windows, horn and heater fan. Defects will only worsen if neglected.

Rubber : The safety implications of under-inflated tyres include the increased risk of suffering a blow out at high speed due to excessive heat building up in the tyre. The legal limit for minimum tread depth on your tyres is 1.6 millimetres, across the central ¾ of the tread around the complete circumference of the tyre

Signage: Observe road, traffic signs and advisory. Road signs and traffic signs are there for a purpose, not just for decorations. Caution signs are shaped triangularly and have red borders; instruction signs are shaped round, octagonal or as an inverted triangle with red color or borders; information signs are round or rectangular in shape,colored white with blue background; direction signs are those round ones with white on blue backgrounds.

Be safe, be seenPeople don’t generally hit what they see – so put yourself where you can be seen. Why stay alongside trucks and vans where the driver cannot see you?

Safe parkingDamage to vehicles often happens in car parks where we least expect it. Think prevention! Use space – park away from other vehicles, trolleys and activity areas whenever possible.

A word to the wise - C.O.A.S.T.S

As experience improves, often attention levels diminish. Get to know what affects a driver’s attention levels and watch for those who are affected. Think COASTS

Concentration : Don’t talk over mobile while driving. Focus on the primary task at hand.

Observation : Pay close attention to other vehicles and changes in their movement.

Anticipation : Anticipate the good and bad intentions of other road users to avoid accidents.

Space : Keep your distance – always maintain a two-second distance behind the car in front of you.

Time : Plan journeys, allowing enough time to arrive safely without the need to drive hard.

Seat Belt : Fastening your seatbelts will not only save your life, but also save you money. It is now mandatory to wear seatbelts while driving and when you are flagged down for not wearing one, the penalty can be quite substantial.

And finally, always be calm and courteous to other drivers.

Use of Plastic Soda Bottles as Light Source

The access to electricity for indoor lighting is very important for any project. A major chunk of electricity is required for indoor illumination during the day time also. To reduce the dependency on electricity, effective use of solar light system is a viable option. Energy conservation has not only economic importance but also environmental aspects. A large amount of greenhouse gases are released during electricity generation. By switching on to solar lighting options, the carbon footprint of a project is greatly reduced.

Water filled soda bottle provides illumination in day light as the water filled inside the bottle acts as a lens and creates an omnidirectional light from the ultraviolet rays of the sun. With the combination of these simple materials, a modified soda bottle solar light can be used for indoor lighting in day time. A typical soda bottle light can generate approximately 50-60 watts of omnidirectional light.

How it is made?

Materials Required

y PET bottles

y Flat or corrugated GI sheets (for encasing)

y Clean water (for filling)

y Bleaching agent like chlorine (to prevent algal growth inside the bottle)

y Industrial sealants

Procedures:

Step I

Cut approx. 9’X10’ GI flat or corrugated sheet and cut a circle slightly smaller (2 mm) than the circumference of the bottle container. Make small strips that will be bent upward the steel sheet.

Infrastructure26 HELMET July - Sep 2013

Page 27: Environment Safety Health HelmetJuly - Sep 2013 • Volume - 3 ...

27HELMET July - Sep 2013

Step II

With the help of steel brush or sand paper scratch the surface of the bottle to allow the glue to stick better. Fit the bottle in the circle and apply the rubber sealant or epoxy resin around the small perpendicular strips.

Step III

Fill the bottle with clear water and add about 10 ml of chlorine (bleach).

Step IV

Cut a diameter similar in size to the plastic container on the roof and place the bottle with the skirt glue directly on the roof.

Step V

Fix the solar bulb firmly in place by drilling 6 holes on the perimeter & riveted on the roof and apply epoxy around the newly cut hole on the roof to prevent leaking. A plastic tube is fixed on the cap to protect the bottle cap from cracking by sun.

Fig: Solar bulbs installed in DMRC CC 06.

Energy conservation:

A typical solar bottle bulb can generate 60watt of light. If a bunch of 10 nos. of solar bulb is installed and is effective for average 8 hours a day it can save 4.8 units of electricity per day and 144 units of electricity in a month.

Importance:

Plastic bottle solar bulb is important in many aspects. The bottle used as bulb is a type of non-degradable waste and is easily available; also the installation cost is nominal. This solar illuminating system can be effectively used in cement godowns, material stores and workmen camp as a substitute to electric bulb for use during day time indoor illumination.

Benefits of Planting Trees

Most often we plant trees to provide shade and beautify our landscapes. These are great benefits but trees also provide other benefits.

Social Benefits

y Trees make life comfortable. It has been shown that spending time among trees and green spaces reduces the stress that we carry around with us in our daily lives.

y Hospital patients have been known to recover from surgery more quickly when their hospital rooms offered a view of trees and greenery.

y Children have been shown to retain more of the information taught in schools if they spend some of their time outdoors in green spaces.

y Trees are often planted as living memorials or reminders of loved ones or to commemorate significant events in our lives.

Communal Benefits

y Even though you may own the trees on your property your neighbours may benefit from them as well.

y Through careful planning trees can be an asset to your entire community.

y Tree lined streets have a traffic calming effect, traffic moves more slowly and safely.

y Trees can be placed to screen unwanted views or noise from busy highways.

y Trees can complement the architecture or design of buildings or entire neighbourhoods.

Environmental Benefits

y Trees reduce the effect of heat through evaporative cooling and reducing the amount of sunlight that reaches parking lots and buildings. This is especially true in areas with large impervious surfaces, such as parking lots of stores and industrial complexes.

y Trees improve our air quality by filtering harmful dust and pollutants such as ozone, carbon monoxide, and sulphur dioxide from the air we breathe.

y Trees give off oxygen that we need to breathe.

y Trees reduce the amount of storm water runoff, which reduces erosion and pollution in our waterways and may reduce the effects of flooding.

y Many species of wildlife depend on trees for their habitat. Trees provide food, protection, and homes for many birds and mammals.

Economic Benefits

y Well placed trees can reduce your cooling costs in the summer by shading the south and west sides of your home. If deciduous trees are used they will allow the sun to pass through and warm your home in the winter.

y Evergreen trees on the north side of your home and shrubs around the foundation of your home can act as a windbreak to reduce the cooling effects of winter winds.

y The value of a well landscaped home with mature healthy trees can be as much as 10% higher than a similar home with no or little landscaping. (Topping will reduce the value of your trees)

Cyclone Preparedness in Construction Sites

Natural calamity like tropical cyclone is a big threat to the construction projects in the coastal areas. Though only 2% accidents are caused due to

natural causes,these verity of the accidents caused by the nature is very high and sometimes can be catastrophic. Implementation of Environment, Health & Safety norms is a big challenge for the construction industry in India. Further this becomes tougher to meet threats from nature such as tropical cyclones, floods, earth quakes, landslides, lightening, etc.

Only proactive approach can reduce the impacts of cyclonic storm. Many lives can be saved and loss of property can be minimised through well-planned and dedicated execution. Some precautionary measures against tropical cyclone are outlined below, but are not limited to:

y Collect information regarding the day, time and intensity of the cyclone from reliable sources (Indian Metrological Department). Follow-up on the updated news and act accordingly.

y Anchor all the containers, porta-cabins, offices to sustain the wind impact.

y DB rooms, sub DB rooms, welding booths and temporary sheds to be rain proof and anchored.

y Firmly secure/load the CGI roofs of the DB rooms, sub DB rooms, welding booths, and temporary sheds.

y Check and remove if any loose material is present at heights.

y Secure CGI sheets, plywood and other materials vulnerable to fly due to heavy winds.

y Secure the scaffolding with fixed structure firmly. Do not keep walkway jallies, H-beams and loose components at height.

y Maintain minimum safety stock/level in cement silos in batching plant.

y Store records, important documents and valuables in a waterproof room/place on the highest level of the self.

y Secure the vertical structures/column which is not braced adequately by providing guy rope.

y Stop erection and other construction activities prior to the cyclone.

y Stop working at height, especially on roofs and temporary platforms.

y Keep all electrical cables and wires tidy and all the electrical joints insulated.

y Secure the temporary members of the structure by bolting or welding.

y Switch off lifts, elevators during cyclonic situation and keep the cabin at ground level.

y Don’t leave any fabricated material in unstable condition.

y Keep booms of all the cranes in down position. Keep boom of the boom placer down.

y Keep Boom of Tower crane in free condition.

y Anchor the gantry crane with all the locking arrangements (track lock, wheel lock, and central lock).

y Provide locking arrangement against travelling in EOT cranes, trolleys and other mobile equipment.

y Cut off power prior to the cyclone.

y Check and keep emergency power supply ready.

y Check and maintain equipment and tools and tackles ready for clearing roads after the cyclone.

y Keep dewatering pumps ready.

y Maintain portable water tanks (overhead tanks) in filled condition at site and workmen habitat.

y Secure doors, shutters and windows of all buildings properly. Secure glass doors, shutters and windows with supports or coverings.

y Maintain the drains and channels free from blockage. Protect the stores from water accumulation.

y Keep emergency lights, torch lights and spare cells ready.

y Keep sufficient food material (non-perishable) and drinking water in canteen and guest houses. Also keep sufficient cooking fuel.

y Keep sufficient fuel for ambulance and emergency vehicles.

y Park vehicles under shelter with hand brakes on and in gear. Provide scotch block.

y Keep public address system ready and spare cells available.

y Keep portable, battery-operated radio with extra batteries.

y Check if all emergency phones are functional.

y Keep required medicines and first aid items ready.

y 36. Keep ambulance/emergency vehicle, first aiders and paramedics ready.

y Keep emergency teams (P&M team, rescue team, first aid and medical team) alert for the situation.

y Keep important telephone numbers readily available.

y Stay inside the building during the cyclone.

y Communicate to the workmen not to panic.

y Communicate to the workmen to avoid resting near structures or inside the construction area.

y If required shift the workmen to safe location.

y Keep adequate amount of bleaching powder, carbolic acid.

y Act as per the guidelines provided by the state administration.

The experience of encountering the recent cyclonic storm – Phailin at L&T’s Kalinganagar Site,Odisha has given the opportunity to share the precautionary measures against such severe cyclones. Though this time it was fortunate that we were not badly hit, it has given us ample scope to learn a lesson and equip ourselves for the days ahead.

Are You Dehydrated?

If you feel thirsty, it means you are already dehydrated.

During exercise, the human body loses a lot of fluids

and it is very important to replace them as soon as

possible. A good way to stay hydrated while working-

out is to drink a lot of water well before you start

exercising.

Causes of Dehydration

Dehydration can be caused by losing too much of

body fluids, not drinking enough water or fluids, due

to excessive sweating,excessive urine output,fever,

vomiting or diarrhea.

Infants and children are more likely to become

dehydrated than adults because they weigh less and

their bodies turn over water and electrolytes more

quickly.

Symptoms of Dehydration

Mild:

y Thirst

y Dizziness

y Light-headedness

y Dry mouth and nose

y Slowed urine production

Moderate:

y Sunken, dry eyes with few or no tears

y Poor skin elasticity

y Rapid and deep breathing

y Low blood pressure

y Fast, weak pulse

Severe:

y Fainting

y Severe muscle contractions in the arms, legs,

stomach and back

y Convulsions

y Heart failure

y Kidney problems

y Lack of urine

y Cool, moist extremities

y Low or undetectable blood pressure

y Peripheral cyanosis (bluish skin)

y Death

Dehydration - Prevention

The following tips may help prevent

dehydration:

y Drink plenty of water before, during, and

after exercise at least once every 15 to 20

minutes

y Do not drink coffee, colas, or other drinks that

contain caffeine. They increase urine output and

make you dehydrate faster

y Avoid high-protein diets. If you are on a high-

protein diet, make sure that you drink at least 8

to 12 glasses of water each day

y Avoid alcohol. They increase dehydration and

make it hard to make good decisions

Dehydration - Prevention

33HELMET July - Sep 2013

Page 34: Environment Safety Health HelmetJuly - Sep 2013 • Volume - 3 ...

34 HELMET July - Sep 2013

y Do not take salt tablets. Use a sports drink if you

are worried about replacing minerals lost through

sweating

y Stop working outdoors or exercising if you feel

dizzy, light headed, or very tired

y Wear one layer of lightweight, light-colored

clothing when you are working or exercising

outdoors. Change into dry clothing as soon as you

can if your clothes get soaked with sweat. Never

exercise in a rubber suit

Dehydration -Treatment

y Move the victim to a cool area.

y Keep the victim in lie-down position.

y Apply cool, wet cloths to critical areas of the

victim’s body (Wrists, Neck, Collarbone, Upper

arms/armpits, Inner thighs, etc)

y Keep the cloths on the body to prevent

evaporation, and re-moisten as needed.

y Give water and juice in small amounts

frequently.

y Seek medical help if the victim is dehydrated from

heat stroke or blood loss, or if dehydration is

severe.

Dehydration can lead to even death. The combination

of heat, high humidity, long exercising outside during

the hottest part of the day, working hard in the sun or

even just walking around in the sun and not drinking

enough water can lead to dehydration related

problems.

Project EHS VISITs

Project EHS visit has been practiced and widely used by organizations to show commitment and identify if the activities are conducted safely.

When such a visit is done well, it helps to drive an organization’s safety performance and culture. It will also help to demonstrate to the front-line workers and line managements, how committed the company is with regard to environment, health and safety.

What goes wrong to a site visit is that people are still doing a site inspection or conducting a checklist style inspection instead of looking beyond it.

In most organizations, a typical site visit involves managers taking some time to carry out safety inspection from his congested schedule and busy morning engagements. After such inspection, he will ask his subordinates to make it happen frequently.

Organization sometimes forgets the aim of such activity and sticks to what was previously been done. Project visits should not be done because it is required and needs to be done. It should be a commitment that aims to check if control measures are implemented well and improved.

The aim of such activity should focus on:

y Assure yourself that things are being done safely,

y Safety messages are getting through,

y Motivate people to work safely,

y Educate people about safety, or better understanding on how to do a particular job safely.

Let’s create a scenario to explain further.

From a busy early meeting, you have a scheduled site visit. Representatives of the project join you on such site visit. Along the way, you see a group of workers, not wearing PPE. You take a picture and ask them to wear PPE. You ask the representatives to do toolbox meeting afterwards and send you the attendance sheet of such toolbox meeting.

What you just did was that you dealt with the symptom rather than the cause.

The questions that should be asked are:

y What is the reason why they are not wearing PPE’s?

Power Transmission & Distribution (I)38 HELMET July - Sep 2013

Page 39: Environment Safety Health HelmetJuly - Sep 2013 • Volume - 3 ...

39HELMET July - Sep 2013

y Is the correct PPE being worn?

y Did they know they have to use PPE?

y Were they given PPE’s?

y Is their PPE’s cost deducted to their salary?

y Was there any problem with the supplier?

y Is the PPE provided to them suitable for the activity?

In this approach, you’re far more wide reaching than simply catching a few people not using the correct PPE. You will be correcting the errors on the system.

You will be motivating them to work safely, apart from, perhaps, motivating them not to get caught working unsafely while you’re away.

On such visits, you have to demonstrate that it’s normal to see you walking around and asking because of yourfor concern for them and because safety is really important to you and the organization.

It is good to involve the people around you by asking them “what else would help you work more safely?”

Another focus that is beneficial on a site visit is the

education about safety, such as posting of signage’s, rules, policies, etc. Most of the observations given as why there is no signage’s. Why policies, rules and regulations are not displayed?

To be more effective, questions such as below should be asked:

y What do these posters mean to you?

y Is this important to you?

y How do they apply to what you do?

y What are the hardest rules to follow? Why?

y What would make things easier?

Highlighting accident statistics relating to identified unsafe acts or conditions will definitely open the minds of workers.

Ultimately, the positive impact generated by one safety visit, focused on addressing a specific problem is enormously useful for the whole organization.

From alternative fuels to low-rolling resistance tires

When you think about green, it’s usually

biofuels, solar power, electric cars which

come first to our minds. There is a need to

expand wider and look for ways to increase efforts to

go green.

One major effort to mitigate climate change is

reducing carbon footprint. Initiatives, studies and

experiments are conducted and yet when it comes to

motoring, greening your car is as much about how you

drive than about what you drive.

Vehicle owners’ intent on conserving fuel and reduce

emissions by driving less aggressively. Definitely,

less aggressive driving will reduce carbon footprint

according to the consumer resource council for an

energy efficient economy who provides green score

rating called GreenCars.

org. Also, it is said that

just one second of high

RPM driving can produce

nearly the same volume

of carbon monoxide

emission as half an hour

of normal driving.

Initiatives on making

drivers aware with

regard to reducing

carbon footprint are

conducted by the

concerned agencies. But

as we said earlier, efforts

have to be extended not

only on behavior but also

on engineering controls.

Way back, fleet manufacturers had already developed

designs that offered fuel efficiency. One among

this is automatic transmission. It simply leaves your

transmission in drive mode through which aggressive

driving is prevented.

More recently, revolutionary achievements are also

getting implemented. If you take a closer look, one of

the contributors for efficiency of fleet is by improving

the oldest technology, the wheel or at least one

crucial part of it. That crucial part is by decreasing

the rolling resistance by up to 3.1 percent compared

to conventional tires. A new compound of silica was

utilized and combined with a coupling agent to reduce

heat generation. Because of these, tires will be easier

to rotate and by doing so, the engine will exert less

effort and fuel burning to make it move.

Another effort that has been experimented and

continuously implemented in Dubai is converting

waste product into compressed natural gas. This

gas is called CNG. With the help of oil companies

together with Dubai government, buses from Dubai

Municipality are now using CNG.

These efforts are truly

essential but there are

many parts of your

car that will wear out

over time, and many

of these can affect

the car’s performance.

Because of these, it is

important to stick to the

maintenance schedule

recommended by your

fleet manufacturer.

By introducing and

improving fleet efficiency

through such innovations

and initiatives to our

transportation systems,

we are demonstrating and moving our focus on

reducing greenhouse gas emission reductions

and conserving our environment for our future

generations.

Climate Change

The topic of climate change is like a puzzle with many different pieces-oceans, the atmosphere, ecosystems, polar ice, natural and human influences. Scientists have been working on this puzzle for more than a century, and while there are still gaps in our knowledge, most experts feel the puzzle is complete enough to show that human activities are having an adverse effect on our planet. This talk look at many of those puzzle pieces, the evidence behind them, and the conclusions we can draw from them.

Scientists have a good understanding of what has changed earth’s climate in the past. Those changes are:

y Sun’s output

y Earth’s orbit

y Drifting continents

y Volcanic eruptions

y Greenhouse gases

Earth’s surface absorbs heat from the sun and then re-radiates it back into the atmosphere and to space. Much of this heat is absorbed by greenhouse gases, which then send the heat back to the surface, to other greenhouse gas molecules, or out to space. Greenhouse gases are extremely powerful heat trappers. By burning fossil fuels faster and faster, humans are effectively piling on more blankets, heating the planet so much and so quickly that it’s hard for Mother Nature and human societies to adapt.

When it caused warming, more CO2 and other greenhouse

gases were released, producing additional warming. But today, the CO

2 released by human activities is far

above amounts in the previous 800,000 years. This CO2

is triggering the increase in temperatures we’ve seen in figure 1.

Certainly, past temperatures have been higher (and lower) than today, and CO

2 concentrations have

also varied. Large global swings were probably caused by such things as changes in Earth’s orbit, which changed the distribution of sunlight over the planet.

Earth is getting warmer by virtually every measure we know, and the temperature has been well above normal. In this sense too, humidity of the air was affected which absorbed more water which in effect cause heavy rains and flooding.

Therefore, each and every one of us has to help each other to reduce carbon emission, reservation of environmental resources and reduce waste disposal. These efforts have been adopted by L&T’s PT&D International Projects. A membership certificate has been given to L&T from EEG (Emirates Environment Group). Along with Emirates Environment Group, we spread the message and conduct initiatives in support of achieving this goal.

You can’t manage what you can’t measure. If you don’t know where you are going, chances are you will end up somewhere.

Measurement is an accepted part of the ‘plan-do-check-act’ management process. Measuring performance is as much part of a health and safety management system as financial, production or service delivery management.

The range of activities undertaken on any organization will create health hazards. Measuring the health of the employees will determine whether the risks on its activities with regard to health were controlled or a need to provide additional control measure is required.

Identifying what might be a factor of health illness will make the organization provide proper control measures or even removal of the cause. There are many angles and ways on how to conduct survey’s for the monitoring of health fitness of individuals. It could be within the data of absenteeism,it could be as per season or even trending as per work activities.

sickness due to weather conditions can be obliterated. Absenteeism also is not critical as most of the employees are not regularly absent. Therefore the most relevant analysis is to check trade type and age criteria.

One of the reasons that employees might have illness is because of the nature of work. For instance, office personnel have the possibility of having abnormal blood pressure (BP) & blood sugar (BS) because physical movements are not frequently being done in their kind of work. Age can also be a factor where physical fitness changes as our body condition changes.

Apart from the recommendation of the medical practitioners, who conducted the test, appropriate corrective action are being introduced such as physical exercise, etc.

Asbestos is a hidden killer

Before it was known that inhalation of asbestos fibers causes several deadly diseases including asbestosis, a progressive and often fatal lung disease and other cancers, asbestos was used in a large number of building materials and other products because of its strength, flame resistance, and insulating properties.

Asbestos was used in asbestos cement pipe and sheeting, floor and roofing felts, dry wall, floor tiles, spray on ceiling coatings, and packing materials. When buildings containing these materials are renovated or torn down, or when the asbestos containing materials themselves are disturbed, minute asbestos fibers may be released into the air. The fibers are so small that they often cannot be seen with the naked eye. The fact that you can inhale these fibers without knowing it makes asbestos an even more dangerous hazard.

It is important to consult a doctor, particularly if the following symptoms develop:

y shortness of breath,

y wheezing or hoarseness,

y persistent cough that worsens over time,

y blood in fluid coughed up,

y pain or tightening in chest,

y difficulty swallowing,

y swelling of neck or face,

y decreased appetite,

y weight loss,

y And fatigue or anemia.

Progressive fibrosis in the lungs varies the severity, progressing to bilateral fibrosis, honeycombing

of the lungs on radiological view with symptoms including riles and wheezing. Individuals who have been exposed to asbestos at home, environment and work, should notify their doctors about their exposure history.

Asbestos warts happen when the sharp fibers lodge in the skin and are overgrown causing benign callus-like growths.

Pleural plaques discrete fibrous or partially calcified thickened area can be seen on X-rays of individuals exposed to asbestos. Although pleural plaques are themselves asymptomatic, in some patients this develops into pleural thickening. Diffuse pleural thickening is similar to above and can sometimes be associated with asbestosis. Usually no symptoms are shown but if exposure is extensive, it can cause lung impairment. Some reports have also linked the condition of pneumothorax to asbestos related diseases.

Nowadays, the only way a person will encounter asbestos is during dismantling old buildings or old installations since many countries have banned such material. To control the risk during demolition or dismantling,only specialized companies are allowed to facilitate such activities. Containment on the area is done to avoid spreading the dust and suitable PPE’s are being used.

Coordination

Audit

The level of support shown by Top Management to EHS is a driver on attaining remarkable EHS performance.A coordination meeting was held by UAE EHS team and headed by Mr. J.S. Sudarsan, Executive Vice President & Head - PT&D on 1st September 2013.

The meeting was attended by key drivers in EHS department within UAE division. They represented 10 individual and ongoing projects with the region.

It was also reminded that Larsen and Toubro has been performing well for the past decade and is still aiming to achieve more. The team should not deter on challenges but use it as a tool to improve.

Such meetings motivates each attendee to deliver more.

The focus of such coordination meetings are:

y Each Project EHS Milestones

y Implemented control measures

y Educational Systems

y Overcome challenges

y Unique and best practices implemented in a project

y Corporate EHS Management support.

Where are we now?One of the important parts of EHS Management System is audit. It is an essential tool to check whether a project is implementing according to the set standards. On 14th September 2013, an audit was conducted at Al Qurayyat City, KSA project. The audit covers the following criteria:

y Management Review y Document and Data Review y EHS Policy y EHS Training conducted y House Keeping & Site Access y Edge Protection y Lifting Equipment & Gears y MS & RA y Fire Equipment y Emergency Preparedness y Sub-Contractor Evaluation y Opening Protection

APPRECIATION

We will continue recognizing good performance

It is proven that motivation improves the quality of work of employees. Some organization thinks that merely giving salary is enough to motivate workers but Larsen and Toubro believes that it needs more than just this. Since human behavior is complex where it differs on the approach of motivation, you can use general motivational strategies or specific motivational appeals. General motivational strategies include soft sell versus hard sell and personality type. Soft sell strategies have logical appeals, emotional appeals, advice and praise. Example of such motivation is our Monthly BEST EHS CONSCIOUS WORKMEN AWARD where individuals are being identified for doing safe works and also an environmental friendly attitude. Hard sell strategies have barter, outnumbering, pressure and rank. Example of such motivation is the yearly appraisal of individuals on achieving set objectives or achieving work description set to him or her.

Dust & Sand Storm

Dust and sand storms are among nature’s most violent and unpredictable phenomena in the Middle East. High winds lift dirt or sand particles

into the air, unleashing a turbulent, suffocating cloud that can reduce visibility to almost nothing in a matter of seconds and cause property damage, injuries, and deaths.

Once you encountered a sand storm while you’re on foot, you can apply these basic tips:

y Put a mask over your nose and mouth,

y Protect your eyes by using sun glass or goggles,

y Get to high ground because sand concentration is high on lower ground,

y Try to shield yourself from any flying objects,

y Don’t try to move through the storm. Wait until storm is out,

When you are driving:

y Outrun the storm when you still have chance to do it but never put yourself in danger by driving very fast.

y If you can’t outrun it, pull over your car and stop,

y Do not attempt to move your car but instead, rest your car in covered area and stay put,

It is advisable to plan ahead your activities to avoid working during extreme weather occurrence. There are ways to monitor an upcoming sand storm by:

y Know ahead where dust and sand storms will occur,

y Dust storms are most likely to occur on hot summer days under certain atmospheric conditions, and meteorologists can frequently predict the possibility of these storms. Tune in to local TV or radio broadcasts before traveling in hot, dry conditions, and consider rerouting or delaying your trip if dust storms are predicted. Roadside signs may also be available to warn you of dust storm danger.

y An emergency procedure and drill should be conducted to know ahead what to do in the event of sand storms.

These are few useful tips that are helpful to avoid accidents during sand storms.

y If possible, avoid wearing contact lenses in areas prone to dust storms. Even small amounts of airborne dust can cause eye irritation and vision problems for wearers of contact lenses and dry, hot conditions alone can cause discomfort. Bring your eyeglasses or goggles when working or traveling in a desert.

y Stay with the group. If you are traveling in a group, do not venture off during a dust storm. You can quickly become hopelessly lost. Members of the group should stay together and hold hands or lock arms.

y Dust storms vary in both size and duration. Most are quite small and last only a few minutes, while the largest can extend hundreds of miles, tower more than a mile into the sky, and last for many days.

y In desert climates, vehicles often create their own mini-sandstorms. This poses a problem for convoys of vehicles, as the constant clouds of dust wreak havoc on moving parts, and impaired visibility can lead to accidents. It can also contribute to respiratory problems for people traveling in these convoys, so bring along a mask and eye protection if you will be traveling across the desert in the open.

Dust storms can be particularly dangerous to those with impaired respiratory function or weakened immune systems. Inhalation of even small amounts of dust can cause potentially lethal complications for people who already have difficulty breathing.

Saving Life by using Fall Arrestor on your full body harness

According to studies, most fatal accidents are caused by fall from height. Therefore it is critical to provide controls to prevent accidents that involve working at height.

We have been exercising the control measure to prevent fall from height risk. Works that has higher probability of fall from heights such as tower installation or maintenance has been using fall arrestor. This operation allows the device to be optimized for the work site while providing the ultimate level of work safety. Trails and trainings are being conducted to make sure that workers are aware and are able to experience the actual and safe execution using the fall arrestor.

As shown in the photos, steps on how to setup a fall arrestor and how it will be used during rescue is given below:

y A full body harness shall be worn by a person as per the manufacturer’s instructions.

y He shall choose a strategic location on where he can anchor the fall arrestor in a reasonable place where if the person falls, he will not be hit or harmed by unwanted materials.

y Claim and place it to the anchorage point identified.

y During rescue, the person that has fallen can be lowered by anyone on the ground using the load extension of the fall arrestor.

When a person falls, it is essential to remove him or her from hanging position to allow proper blood circulation in the body. Most of fatality also happens due to blood stoppage where blood circulation was not rehabilitated.

Even if the objective of the fall arrestor is to protect a person when he falls, unsafe condition of fall arrestor might also cause accident. Inspection of the arrestor shall also be done on a monthly basis and before using the fall arrestor.

List of things to check but not limited to are:

y Have the manufacturer complied with EU standards

y Are there any broken parts, cuts, missing parts, corroded or dirty parts

y It shall have a safe working load not less 2275 kgs or 5000 lbs.

Conducting High Voltage Testing and Commissioning

High voltage testing is one of the most hazardous activities that will be engaged by any construction team specifically during the last phase of a project.

It requires experienced and expert engineers to execute the activity with the presence of client and consultant.

The hazards and risks including required control measures shall be discussed with all before starting work.

As electrical wave can also happen during the testing, it is recommended that a minimum of 2 meters and if possible wider range shall be barricaded and restricted for any entry or approaching distance to the live equipment.

It is always required to drain the line every time supply is given into the system to avoid any leftover electricity that might be a cause of an accident.

Basic safety control to be checked during testing and commissioning are:

y Isolation on both end points to be confirmed,

y Setup of reactor and parts are done properly and confirmed by the testing engineers from Client and L&T,

y Discharge rod and HV insulated gloves are used as suitable for the activity.

y Restriction signage’s and barricades are clear and visible.

y Emergency kit and fire extinguisher are available at site.

y Watchman should be assigned in all corners including blind spot should be assigned to restrict any entry during supply of electricity.

Man-Machine Interface and Vehicle Reversing Safety

Across the global motor fleet industry, reversing incidents are invariably one of the top 5 collision types encountered by most organizations, and with their high potential for asset damage and injury to bystanders, drivers are being urged to take more care while travelling backwards.

The need for fleet managers and drivers to become more aware of the dangers has been emphasized through toolbox meetings and DEMO program initiatives which targets reversing safety. Such programs send an alert and warn that reversing often affects the most vulnerable of road users such as riggers, adjacent workers, pedestrians and outdoor workers. The program provides practical steps to reduce the risks involved in vehicle reversing safety.

Potential hazards while doing reverse parking can be classified as:

y Person struck by reversing vehicle and injury

y Vehicle collision and possible fire hazard

y Property / material damage

y And workers come behind the mobile equipment without any reason

To eliminate or reduce the risk relating the reverse movement of vehicles, control measure can be implemented as follows:

y Provide separate entry & exit for the equipment

y Operator should follow the instruction of signal man/banks-man/flagman advisor signals

y Operators & driver should inspect their machine before starting the work

y Keep eye to eye contact between vehicle operator and worker

y Install soft barricades around the work area

y And worker should stand at least 10 meters away from any moving machine or heavy vehicles

HOW TO REVERSE SAFELY? ¾ Find safe alternatives to reversing if at all possible.

¾ Walk around the vehicle and look for obstacles or hazards before moving.

Safety Demo using mannequin

¾ Reverse slowly - turn your head, use your mirrors and check both sides.

¾ Avoid reversing over a long distance.

¾ Look behind before reversing – not as you take off.

¾ When reversing and turning remember to watch the front of your car as well.

¾ If towing a trailer, practice reversing with the trailer in a safe location.

¾ Check for nearby pedestrians and traffic all around, in front of and behind you, over both your shoulders and in your mirrors.

¾ If your view is restricted, ask for help when reversing.

¾ If you are in doubt get out of your vehicle and check the area.

¾ Give way to other traffic or pedestrians.

¾ When reversing from a major road onto a minor road, wait until it is safe. Reverse slowly far enough into the side road to allow you to take up the correct position when rejoining the major road.

¾ You must not reverse from a minor road onto a major road as it is unsafe to do so.

¾ Take extra care when reversing in darkness.

Construction Safety Practice

Let’s have a look at some guidelines set by Dubai Municipality under Code of Construction Safety Practice

The current Construction Safety Manual called Code of Construction Safety Practice is designed to regulate the working conditions in construction projects for all employees who work with contractors or sub-contractors. It covers sensitive activities in construction that are identified to be a key factor to prevent accident from happening and arrangement that are required to be setup to address any emergency situations.

Since the coverage of such manual is wider, this article will only cover some requirements and guidelines that are widely important to any project.

The deployment of safety personnel’s to monitor, advice, educate, and set control measures to prevent accident.

One of the important arrangements is the deployment of medical practitioner to attend to emergency medical needs.

Without adequate and suitable sanitary facilities, health condition of the works will be affected. It is essential that arrangements on such facilities are complied to. Below are the guidelines set by the manual.

Most of the noises that creates stress to

a person defers from the level of sounds

that you can handle or even what type

of sounds you are hearing. Construction

creates a lot of un-wanted sound. The

manual has cited guidelines to avoid stress

caused by any unwanted sounds.

Our eyes are one of the most important parts in our body. By saying that, it is important to identify and set control measures to prevent any damage of it. One possible cause that our eyes will deteriorate is because your lighting is not bright enough to handle specific activities.

On this manual, clear guidelines are set to make sure that proper lighting will be provided to prevent damage to your eyes due to lighting. Below are the guidelines set by such manual as per specific work.

Even personal protective equipment are identified and should be considered as the last self-defense against injuries and accident, it is also an important part of a control measure to individuals from any hazardous impacts in the workplace.

Personal protective equipment called PPE can be identified as helmet, mask, gloves, ear plugs, goggles, full body harness, vest, safety shoes and coverall or any clothing protection.

“Living on the earth is expensive but it includes a free trip around the sun each year.”- Unknown.

Solar power is becoming a fast growing energy

source partly fueled by the belief that sustainable

energy sources are the answer to global warming and

increasing costs of power. Solar panel systems on a

building are also a way of demonstrating commitment

to improve the environment. Commercial world

treated solar power panel system as a grand success

immediately after it was launched, but they also put

potential challenges for fire safety professionals across

the world. It is mainly because there are no proven

standard protection concepts currently available as

it is a new and emerging technology and complete

research on the fire risks as well as safety operations

are yet to be done.

Hazards

In US, Germany, and rest of European countries

where there are more roof top solar panel

installations, there are cases of frequent major fire

incidents.

A more deliberate hazard is that in this case of fire

using of water and fire fighters moving over the Roof

is more dangerous as there may be possibilities of

electrocution.

Hazards due to the solar panel system can be classified

into two categories.

1. Electrical hazard

y With activated panels, the cable that run through

and over the building are always ‘live’, with

potentially dangerous levels of direct electricity,

until they reach the first isolator switch.

y Even when the switch is off, the cables remain live,

and so do the panels as long as sunlight comes into

contact with them.

Solar Risk

y A solar panel array produces hundreds of volts, a

shock from which could be fatal to fire fighters

attending an Incident at the building with solar

panel installations.

2. Fire hazard

a. Fires initiated by the solar panel system

1. The solar panel systems are subjected to faults like

any other electrical systems such as arc faults, short

circuits, ground faults and reverse currents which

can produce fire.

2. The system specific failures like cable insulation

break down, rupture of a module, and faulty

connections, can result in hot spots that can ignite

combustible material in their vicinity. Wrongly

installed or defective DC/AC Inverters have been

the reason of several photo voltaic fires as well. In

worst cases, it will result in DC arc which is known

to be one of the main reasons for the larger roof

top fires.

3. The DC arc can further develop as arc flash

when there is a sufficient amperage and

voltage, hence, more chances for this to happen

in solar panel system, because of continuous DC

current (> 10 A) and high voltage (300 – 1000

V) involved that can develop heats as high as

30000 C (even metals can melt at this range of

temperature).

b. Combustibility of the solar panel system

It is the property of the solar module system

to catch fire when there is prevailing external

fire/ fire accident in the building. The frames,

cables, mounting systems and boxes can add

to the combustible loading of an installation

and eventually to the combustibility of the

entire roof.

Precautionary Measure prior to start of Construction Activity at a Roof top Solar System:

Precautions:

1. Prior to start of Installation / Construction activity on the Roof, a survey can be made on the Roof material, load capacity of the roof, fall arrestor systems, Access egress to Roofs, adjacent buildings and other precautionary measures.

2. The first line defense is the quality of the components and the installation as well as presence of protective devices for the entire electrical system.

3. Standard procedures for installation and safety operations are to be strictly followed.

4. Proper installation of isolators can serve as life savers at the time of fire operations that can reduce the DC currents and voltages to levels which are no longer harmful.

5. Installation of “fireman’s switch” can prevent electrical dangers.

6. All components of a solar panel system exposed to sunshine and other exterior elements of weather proof need to have highly durable characteristics.

7. Fire resistant insulation system can reduce the arc effect to a great extent.

8. The installation arrangement must be made in such a way that sufficient free space is available for fire crew for their operations at the top of the roof.

9. All the isolators, control panels should be easily identifiable during fire operations.

10. All persons working on roof top solar systems are to be trained with working on roofs and the fall arrestor systems.

11. The customer shall be aware of the lifetime of the panels, cables and other accessories to have a proper preventive mechanism in place.
