personnel and shall provide for: - Facilities for administering first aid - Periodic medical examinations - Arrangements for professional medical treatment - Hospitalisation



The Contractor shall ensure that all its personnel are medically fit to perform their work. If requested by HOCL, the Contractor shall provide health certificates for its own and sub-contractor’s personnel.

The Contractor shall ensure that all his tools, tackles and equipment are inspected. The contractor shall in the execution of the work be fully responsible for compliance

with: a) Relevant local national and international laws and regulations. b) The Company’s regulations c) Local, national standards or codes of practice, whichever are more stringent

unless specified otherwise. d) International standards or codes of practice whichever is the more stringent

unless otherwise specified. The Contractor shall appoint one of his personnel on the work Site as safety

advisor/officer and shall seek the Owner’s approval for the individual so appointed. The Contractor’s Site-in-charge, shall be responsible for co-ordinating the with the

worker’s safety activities. The Contractor shall at its own expense ensure that all its personnel and sub-contractor’s

personnel have been given the necessary safety, survival and job related training required by law.

7.4 House Keeping

The Site shall be kept clean and tidy at all times to prevent hazards and improve general

working conditions. Rags, paper, wood shavings and other flammable materials shall not be scattered over

and shall be collected and disposed of in sufficient frequency. Temporary electrical cables shall be installed as not to cause a tripping hazard to

personnel, nor be liable to mechanical damage by equipment. Cables joined by tapes are not permitted for power tools and welding sets. All electrical tools shall be grounded.

Elevated cables shall be installed at such a height as to allow unrestricted movement of

construction equipment and vehicles. The area where piling is going on should be kept clean to avoid accidents due to slippery

ground. Equipment or materials stored at the Site shall not obstruct access to essential facilities

and/or equipment, such as fire extinguishers, fire hydrants valve, gauges, emergency exists, etc.



7.5 Personal Protective Equipment

7.5.1 Head Protection

All personnel shall be issued with safety helmets, which shall be used at all times that

personnel are on the site. Safety helmets shall be checked periodically for signs of wear, and in particular for

cracks in the shell, and damage to the hammock. Any evidence of such wear shall result in the helmet being discarded, and a replacement issued.

7.5.2 Hand Protection

Gloves shall be used by personnel involved in works, for possibility of the following

hazards: - - Risk of abrasion - Risk of cutting - Risk of tearing - Risk of chemical, or other, burn - Risk of infection The wearing of gloves should be avoided if possible, when works are being carried out

on, or immediately next to rotating or moving equipment.

7.5.3 Foot Protection

Suitable safety footwear shall be worn by personnel, considering the nature of works and

such hazards as: - Risk of crushing by heavy objects - Penetration by sharp objects - Penetration by chemicals or harmful liquids - Weld spatter

7.5.4 Eye Protection

All personnel shall be provided with suitable eye protection wherever there is a risk from - Flying particles - High speed flying particles - Dust ingress - Chemical splash - Radiation glare - Hot sparks or metal spatter - Harmful vapours



The correct selection of eye protection shall depend on the assessment of the risk, or

combination of risks, based on the site situation. Eye protection with scratched or ‘fogged’ lenses shall be discarded, and replacements

issued.

7.6 Plant, Tools and Equipment

The following four basic principles shall be applied to and govern the safe use of hand

and power tools and which principles are: - To choose the right tool for the job - To use only tools in good condition - To use the tools correctly, and only for the purpose intended - To maintain and store tools properly Hoses supplying air to pneumatic tools shall be inspected for signs of wear or damage,

and connecting clamps proved secure. High speed rotating equipment, such as grinders, shall be fitted with protective guards. Grinding discs are rated by the speed at which the disc rotates, and this must be

compatible with the rotational speed of the grinder itself. Power tools shall never be left operating unattended. The Contractor shall carry out periodical inspection of plant, tools and equipment. Loads must always be slung with the center of gravity directly beneath the crane hook, to

prevent uneven tensions being applied to the sling legs. The angle between sling legs shall not, under any circumstances exceed (100 deg), as

this doubles the tension on each leg, thereby reducing the lifting capacity of the sling by 50%.

One (1) person only, usually the Supervising Rigger, shall give instructions to the crane

operator. For wheeled cranes, outriggers shall be used for each lift, regardless of the size, and shall

always be fully extended. A ‘trial’ lift shall be carried out, raising the load a short distance above its pick-up point,

to check the stability of the crane, and the efficiency of the brakes. The load shall, at all times, be kept as close to the ground as possible.



Whenever possible, and after lifting the load from its pick-up point, the radius of the lift should be shortened to increase the crane’s lifting capacity and stability.

Wire slings and chains under direct tension during the lift shall not be extended

artificially, not be knotted. Wire slings which show signs of excessive wear, kinking or broken wires shall be

discarded and not used further. Shackles shall be complete with the original pin, and under no circumstances shall a

substitute bolt be fitted. At no time whilst the crane’s machinery is running, shall the operator leave the cab. At no time whilst a load is suspended shall the crane’s engine (s) be intentionally turned

off. At no time whilst a load is suspended, shall personnel perform any works directly

beneath. Particular consideration to the presence of low-level structures such as pipe bridges shall

be given where crane is to move about the SITE. Consideration shall be given to prevailing weather conditions, and where a greater than

normal risk exists, the lift shall be postponed until more favourable condition is developed.

7.7 Safety In Instrumentation

Only authorised persons shall carry out operations and maintenance of instruments and

control system. Ensure isolation of the instruments before taking up the work. Display “Look Out”

Board. Use proper protective equipment. Check for defective cables, cracked or perished insulation, loose joints in conduits,

damaged fuse boxes terminal boxes, junction boxes, loose pins, faulty sockets and defective earth wire.

Do not overload instruments. If the fuse blows, report it. Do not fit fuse wire without

ensuring safe condition. Avoid kinking or twisting, binding or crushing of cables. Do not use portable tools near inflammable vapour or gases.



Ensure that all the equipment are suitably earthed. Use right type of tools for the jobs. Do not let cables trial across the floor. To disconnect equipment do not pull the cables. Pull the plug After maintenance of flameproof fittings, ensure that the fittings meet requirements of

flame fittings. Arrange all machinery such as welding machine, generators, cutting machine etc. in such

a way that special fire risk equipment are segregated and protected. Check the machines at periodic intervals. Never over heat the machines Do not accumulate unwanted material near the machines, which may cause fire hazards. DCP type fire extinguisher must be kept. No smoking board should be displayed at

various points. Do not store wet or oily materials and materials like coir, jute, cotton gunny bags etc.,

they can ignite spontaneously. Store chemical and other such goods in stable racks properly labelled. Mutually reactive

chemicals should be kept away from each other. Hot goods must be arranged so as to allow safe cooling and should not come in contact

with combustible material. Tools which are returned back after use must be kept at a earlier marked place so that it

can be traceable immediately and proper stock can be kept. Storage place should have proper ventilation Electrical, welding, cables should be stored properly and secured from theft. ‘No smoking’ boards should be displayed in store. Instruments should be properly secured. No other work such as repair of machinery, testing of grinding machine or whatsoever

should be done in a small workshop shed, which is temporarily constructed at site. Electrical tools shall be checked to ensure the supplied voltage is comparable to the

machine’s design.



Electrical leads and connections shall be inspected for signs of damage or wear, and repaired or replaced accordingly.

At no time shall two (2) or more power tools be connected to a single power plug.

Wherever required, electrical tools shall be properly earthed. Fuses means as a source of protection and safety can become hazardous if not selected

and maintained carefully. Ensure all fuses are of good quality and conform to correct ratings. MCBS are better

than ordinary fuses. Instrument maintenance workman working around a wet area near a fuse box must use

wooden platform, insulated tools or rubber boots. Always replace a fuse with the same type and size as the original, for e.g. a copper wire

or other conductor must never be used as substitute.

7.8 Safety Working Practice for Mechanical Job - Fabrication and Welding

7.8.1 Gas Cutting and Welding

Gas cylinders used in cutting and welding shall:

• Be stored separately, depending on the type of gas contained, and whether empty

or full. • be stored upright, and shielded from direct sunlight or other heat source • be stored in a well ventilated area • be fitted with safety caps when not in use • be properly secured during transportation

When handling cylinders, ensure hands, clothes, gloves, etc. are free from oil, dirt, grit and grease. Under no circumstances shall oil be allowed to contaminate a cylinder containing oxygen.

All gas and oxygen regulators shall be fitted with Flashback Arrestors, being non-return

valves designed to prevent an explosive mix developing in either cylinder. Such explosive mixes can occur due to loose connections, leaking hoses, etc.

Prior to use, all equipment shall be thoroughly checked to ensure that: - all connections are ‘right’ - all fittings such as gauges, flashback arrestors, etc. are functioning correctly - hoses are in good condition, and free from signs of cracking or perishing - checking for leaks shall be by means of soapy liquid applied to each joint.



Under no circumstances shall a naked flame be applied to any part of the Cylinder or Hose arrangement to detect leaks.

The cutting and welding of certain metals, or metal coatings such as zinc galvanized

surfaces give off harmful fumes and such works must, where possible be carried out in a well ventilated area.

When working at height, do not place cylinders directly beneath the work area, as molten

metal may fall onto hoses, causing leaks, and possibly lighting the gases.

7.8.2 Electric Arc

During the electric arc welding process, very high ultraviolet radiation is generated.

Suitable eye protection must be worn by the welder, and any other persons working in a close proximity to the welding works, in order to prevent permanent damage to the eyes.

When not in use, the current to the holder and electrode must be turned off. All equipment must be properly earthed and cables securely connected. All equipment must be thoroughly inspected prior to use, and cable connections shall be

completely insulated to prevent injury from electric shock.

7.8.3 Standard Practices

Ensure the work area beneath or adjacent to fabrication or welding works is free from

combustible materials, and cordoned-off to prevent personnel being injured by weld spatter or molten metal.

Retain a dry chemical fire extinguisher at the location of fabrication or welding works at

all times.

7.8.4 Working Platform

Wherever possible, all works to be carried out over water or at a height greater than (2.0)

above the ground level must be performed from a properly constructed and maintained working platform.

The working platform shall be:

- closely boarded

- at least (0.7 m) wide if used only as a footing

- if used to store materials in addition, at least the width of the materials plus (0.7 m)

- provided with toe-boards of minimum (0.15 m) in height



- provided with handrails not greater than (9.05 m) above the toe-board

- constructed as close to the structure or building as possible

- Boards to be used on the platform shall be of a suitable thickness, in due consideration of the spacing of supports beneath

- supported by at least (three (3)) transom, (or cross-supports)

- Not project beyond the last support by more than twice their thickness

- be adequately fastened to prevent slippage or movement during use

- Wherever possible, not overlap another board

- be free from cracks, twists, holes or other defects which may affect the load bearing strength

- protected from weathering by means of a clear preservative. Boards shall never be painted as this disguises defects

Scaffolding shall be properly designed and erected with its intended use in mind

where additional, anticipated loads are to be applied; the structure shall be redesigned and modified accordingly.

Mobile tower scaffolding shall be fitted with lockable wheels of a minimum (0.12 m) in

diameter. The height of the working platform not greater than (3 times) the shorter base dimension. All working platforms shall be kept clean and free from grease, oil, rubble, debris or

rubbish to ensure safe movement for personnel performing the works.

7.8.5 Ladders

Wooden ladders shall be checked such as splits in the rungs or stiles, unduly worn rungs,

loose wedges or tie rods, and split or frayed feet. Wooden ladders shall be protected from ‘weathering’ by means of a clear preservative.

Wooden ladders shall not be painted as this disguises defects. Metal ladders shall not be used where overhead electric cables are present. Ladders to scaffolding shall be clamped at a minimum of (three (3)) points and shall

extend a minimum of (1.0 m) above the level of the platform it accesses. In other situations, ladders shall be clamped near the top to a convenient point, and

sloped with proper angle, (base : height ratio 1:4)), to the horizontal, to limit the risk of slippage.

If the nature of the works is such that both hands are required to perform those works, a

safety belt, secured to the ladder must be worn at all times.
