Safety Tips for Service Engineers

Due to the nature of after sales service, most servic-ing work is performed on the customer premises.

Therefore, it is necessary for the service engineer to

be especially mindful of safety since an accident could

not only cause bodily harm to the concerned service

engineer, but it could also cause personal or property

damage to the customer and bring ill-will to the com-pany's reputation. Furthermore, servicing on-site

often means working under a variety of adverse condi-

tions and requires even more attention to health and

safety than the familiar conditions at the company.

For these reasons, we ask that you diligently observe

the stated principles below in performance of your var-ious duties and pay extra special attention to health

and safety to ensure good health and spirits in the

performance of your daily work.

1) Most importantly, be sure to observe the

safety rules of the customers.2) Perform short morning exercises to phys-

ically and mentally prepare for the start

of the day.

3) Work safely and always remember your

original purpose. (Never neglect your

duty.)4) Be conscious of your health and maintain

good, healthy practices daily.

5) Never stick your hands into your pocket.

6) Greet people in a loud and clear voice.

1. Safety Tips for a Variety of Jobs

1. Elevated Worksites

Accidents caused by electricshocks or falls from elevated

places tend to be fatal when

they happen. Listed below

are common places where

falls occur.

Footholds, ladders, step-ladders, scaffold boards,

or similar.

Pits and other openings in the floor. Roofs accidents during work tend to take place at

relatively low elevations such as elevations of 1-2

meters. Never consider the above-mentioned ele-vations low and keep your guard up.

Don't fall or drop any-thing.

To prevent from dropping

tools, put them in a tool bagand tie the bag to a rope.

Keep from slipping or

tripping. Pay careful attention not to

slip on the roof or stairs due tosteep sides or slippery condi-tions.

Pay utmost care not to stepon cylinders, tools, or otheritems. Doing so will result in a series of adverse condi-tions such as unstable footing.

Since it is easy to trip, especially when you are carry-ing things, be careful when you are stepping on roofingtiles or in the ceiling. (It is recommended to use scaf-fold or running boards.)


9/125

6

Use a safety belt. When conducting any ele-

vated work, be sure to use asafety belt and a life rope. If

there are no places availableto hook on the safety belt,use a lead rope or similar.

Wear a hard helmet. When conducting any ele-

vated work, be sure to wear ahard helmet. Furthermore,when working in a plant, in amachine room, on a con-struction site, on the rooftopof a building, or other work-

site, it goes without sayingthat you should wear a hardhelmet.

Use a protective footcover.

When conducting any ele-vated work, use foot coversfor your trouser legs.

Precautions for use of a ladder. When using a ladder, be careful not to let it fall. Do not allow anyone to

go up or down the lad-der people backwards.


10/125

7

Falling or flying objects can cause accidents.

(1) Do not allow anyone to throw objects from above.(2) Do not store any unnecessary materials or tools in

elevated places. If you must store them in an ele-

vated place, be sure to secure them.

(3) When using tools that can fall, attach a string to

each tool and tie the string to your safety belt.

(4) Enclose danger zones with warning ropes for fall-ing objects and plainly display danger signs.

Example-1 Example-2

Use a bag to hold small

items, tools, and other items.

2. Electrical Servicing

Receiving a shock regard-

less of amount of voltage

will result in a serious acci-dent. A shock received in

an elevated place is espe-

cially dangerous since this

shock could result in a

fatal accident from falling.

Be sure to turn switches ON or OFF with yourright hand, opposite of your heart. Do not

attempt to use a rod or other objects to operate

switches.

First, turn switches OFF.

Before starting any work, be sureto turn the switches OFF. Make it a rule to request the cus-

tomer representative to turn theelectricity ON or shut it down.

Remember that the customer'sfacilities can also be the cause of aserious accident.

* Do not turn any power supplyswitches OFF since they may beconnected to the power supply.

Indicate that work is in progress Be sure to put a red tag indicating"WORK IN

PROGRESS. DO NOT TURN ON POWER SUPPLY"

at the power supply switchbox in use. Do not turn the switch ON

with a wet hand. Never turn the air circuit

breaker OFF while in opera-tion and the power is applied.Check to be sure no loadsare applied and then turn theair circuit breaker OFF.

Do not measure high volt-ages with a small capacitymultiple meter (from serviceengineer's personal belong-ings).


13/125

10

In addition,

Be sure to check that the circuits are shut-

down, when performing megger testing and

working with high voltage circuits.

For power circuit breakers of 600 V or more,request that the customer representative turn

the circuit breakers ON or OFF.

Shutoff check Before starting work, be sure

to check with a multiple meterthat the power circuits are

shutdown.

Discharge of phase advancing capacitor andinverter capacitor

For any units equippedwith a capacitor, be sureto establish groundingand then start circuit-related work.

Insulation tests When turning electricity ON

for the first time, be sure toperform insulation tests.

Do not turn the switch ONwith wet hand.

Signal to turn electricity ON When turning electricity

ON, be sure to signal yourco-worker and exchange

signals for establishingreadiness.


14/125

3. Welding(Gas Welding / Arc Welding)

Obtain permission from the customer representative

to conduct welding work (or any work involving theuse of an open flame).

No one shall be permitted to weld unless he/she has

been authorized to perform welding.

Use of protectiveequipment

Be sure to wear proper pro-tective equipment.

When performing any typeof arc welding, always besure to wear leather gloves.

Keep area clear of hazardous substances orflammable material

Check to be surethere are no hazard-ous substances orflammable materialaround the weldingworksite, and per-form the work with abucket of water or afire extinguisherhandy.


15/125

12

Protective care When welding in the vicinity

of flammable material, pro-tect the material with the use

of a nonflammable protectivecovering (e.g. tin plates,asbestos, or fire-resistingsheets).

Pay close attention Since the welded object

retains a high temperaturefor a long time, be carefulnot to burn any part ofyour body. After the com-pletion of welding, confirmthat no flames haveleaped. (Always clean up

after welding and ensurethat no source of ignitionremains.)

Be sure to provide ventilation (exhaust). When you work in an

enclosed room or inside atank, take extra care to pro-

vide ventilation (exhaust) tothe workplace due to highpossibility of explosion, firedisaster, oxygen deprivation,or gas poisoning.

When required, provideforced ventilation to the work-place (using a fan or otherdevice). Avoid welding independently without a partner.

Never weld in an atmosphere containingchlorofluorocarbon.

Welding in areacontaining chlorof-luorocarbon gas

will generate phos-gene, resulting inan imminent haz-ardous situation. Inthis case, be sureto provide thor-ough ventilation.


16/125

4. Transportation

Devise a proper method for transporting equipment

and materials. For heavy items, use carts, lifts, dollies

and similar equipment. Avoid depending on man-power whenever possible.

{ If you feel it is impos-

sible to transport the

goods by yourself,

request profession-

als.

Teamworkrequires gettingalong with co-workers.

It is important to coordi-

nate activities by follow-ing the leader's signal.Working alone withoutcommunicating with co-workers will result in hazardous situations.

Ensure transportation methods and worksetup.

Transport heavy itemsunder the supervi-sion of skilled, experi-enced workers.Failure to do so islikely to cause acci-

dents and otherinconveniences.Careful thoughtshould be given to thetransportation meth-ods, the work setup, and other work-related consider-ations.


17/125

14

Follow instructions from the leader of trans-portation work.

Act under instructions fromthe leader.

Should something fall, getout of the way and do notattempt to support the fall-ing object.

Watch your step. Keep workplaces andpassages clean and tidy.

In dark places, provideproper daylight and light-ing.

For transportation onrainy days or on a wetfloor, particular attentionshould be given to yourstep.

Lift using your legs. Do not attempt to transport

substantially heavy itemsalone. Do not hesitate to askyour co-workers to help you.

Be especially careful whentaking the stairs with hard-to-carry items such as R-11, N2,or gas cylinders or otheritems.

Note that bending over to liftheavy goods may result inlow back injuries.

Be attentive to your uniform. Check to be sure your outer clothes

or trousers bottoms are tucked. Be sure you are not going startwork with bare skin exposed.


18/125

5. Transportation hazardous substances(e.g. high pressure gas)

Hazardous substances should be carefully trans-

ported.

No Lay Down No lay down permitted

to transport chlorofluo-rocarbon, acetylenegas, or oxygen cylin-

ders by car. Securelyfix to prevent themfrom swaying and fur-ther arrange the cylin-der caps not to faceeach other.

Keep container temperatures at 40C or less. Since parking a car

under the scorching suncauses a sudden rise intemperatures inside ofthe car, special atten-tion should be paid tothe storage of contain-ers in the automobile. Ifthe temperatures canrise, take measuressuch as opening thewindows or coveringwith a sheet. (Laws and regulations require containersto be kept at temperatures of 40C or less.)


19/125

16

Warning sign Be sure to put a warn-

ing sign stating "HIGHPRESSURE GAS" on

service cars, respec-tively.

Drive service cars with great care. Do not make sudden starts or a stops. Pay attention to tight

turns and carefullysteer the service car.

Accessories for high pressure gas use

Always have and checkaccessories (e.g. fire extin-guisher, red tag and othertools and equipment).Also, make sure that thedocument "Advisory notefor disasters prevention intransport" is in the service

car.

6. Driving Safety

Observe the road traffic laws to ensure safe driving.

Be sure to conductdaily start-up inspec-tions.

Prior to departure, always be

sure to conduct the dailystart-up inspections. No oneis allowed to fill the runningschedule form by referring tothe tachograph after return-ing to the company.

Strictly observe trafficrules.

Keep patient and drive safelyeven when you are in a hurry.

Be sure to drive with yourseat belt fastened.

Reckless driving such as

driving a car at excessivespeed, ignoring traffic lights,or other violations may resultin an accident.


21/125

18

Driving while feeling sleepy or looking asidewhile driving may result in an accident.

If you are sick or overworked,report your condition to your

supervisor and refrain from driv-ing.

Never drive a car when you feelsleepy. If you feel drowsy, imme-diately stop your car and have abreak.

Your fellow passenger should

confirm safety when making turnsacross intersections. When driving in rainy conditions, drive with caution and

pay attention to slippery conditions.

Reverse or turn the car with caution. Check to be sure there

are no obstructionsaround the car and thenput the car in motion.Your fellow passengershould get out of the car

to give instructions.

Securely store tools and parts on board. Securely store the car keys to

discourage theft of the carand/or theft or loss of toolsand parts.


22/125

19

Do not park cars illegally.(Explanations provided here refer to Japanese

laws. Please rewrite this section in accordance

to local laws.)*A partial revision was made to the Road Traffic

Law.

(Enforced in January 1991)

Parking violation control has been tightened.

After repeated parking violations with a company-

owned car,

A warning is given to the company.

Penalties for individual drivers (points on licenseand parking fines) have been increased.

Three parking violations in one year or a flagrant

parking violation will result in a ban in the use of the

car concerned.

NOTE:

If you commit a parkingviolation, make a report ofthis violation to the person incharge of vehicles.

{ Observe customer rules and be sure

to have preliminary meetings with thecustomer's representative prior to

work.

{ Request the local representative to

accompany you and receive instruc-

tions from this representative.

Do not use openflames.

Use or borrow explosion-proof type of work lights

(flashlights) specified by cus-tomers. Failing to do so mayresult in ambient gases ignit-ing and causing serious inju-ries or even death fromexplosion, fire, or similaraccident. For this reason,never smoke in any place

other than designated smok-ing areas.

Do not use gas leak detectors (halide type orelectric type).

If electric type gas-leak detectors are not available,perform the following:

Use soapy water or similar test(Do not light a match or turnon the power supply.); usenitrogen gas for gas leak (air-tight) tests. (Never use carbondioxide, air, or oxygen.)


25/125

22

Have fire extinguishers on hand at work-sites.

Keep fire extinguish-ers handy when per-

forming work. Fire extinguishers

other than halogenones are prohibitedfrom computerrooms.

Do not make sparks. Perform performance tests on pressure switches, ther-

mostat, and other items within a casing (explosion

proof enclosure). Be sure to turn off the powersupply before making anyadjustments. Pay extra atten-tion not to make sparks byhitting tools, pipes, or othertype of metal.

Car traffic Attach a flame pro-

tection device to theexhaust pipe of the

service vehicle inthe specified trafficarea.

Park the service carin places specifiedby the customer. Donot park it in thevicinity of firehydrants or door-ways.

8. Miscellaneous safety precautions

Recovery of refrigerants with caution Recovery of refrigerants in

basements with caution andprovide thorough ventila-tion. Failing to do so mayresult in a shortage of oxy-gen.

Toxic gases may result fromrefrigerant that comes incontact with an open flame.

If there are manholes, check to be sure there are noworkers in the manholes. Please note that refrigerantsare heavier than air and flow into low places resultingin shortages of oxygen.

Please note that touching liquid chlorofluorocarbon willresult in frostbite.

Operating equipment in basement

Locate emergency exits prior to working in basements.

Confirm contact information beforehand in case ofemergencies. (e.g. supervisor).

Check to be sure the ventilating equipment (exhaust) isoperational.

Put tools (hand tools necessary for services) in order.(Keep these tools close to the area of first use.)

Conduct work in basements in teams of two people. When working in basements or closed rooms, carry

audible alarms for detecting lack of oxygen.

Put a flashlight in your pocket (used for escape or writ-ing report in the case of power failure).


27/125

24

Handling and disassembly of pressure ves-sels

Take fall prevention measureswhen using N2 or O2 cylinders.

Check for residual internal pres-sure prior to disassembly orwelding of pressure vessels.

When disassembling head cov-ers, flanges, or other items from

a compressor, do not remove allbolts at one time. Loosen bolts first to make sure thereis no internal pressure, and then remove.

Valve opening/closing When starting a test run of

the refrigeration unit, recheckthe valves to ensure properopening and closing.

Perform halide torch method for gas (refrig-erant) leak detection with caution

Confirm that the gas detectorflame is extinguished before

filling alcohol to preheatingunit.Be careful not to overturn thegas detector during preheat-ing.

While the gas detector is inuse, do not operate the valve

around your face.


28/125

25

Marine vesselWhen conducting marine vessel-related work,

always complete customs procedures when

embarking and disembarking.

(1) Never jump onto or off the vessel.

For transferring from a boat to the main ship, board themain ship after the boat has been tied up to the main

ship. Watch your step, especially when the water ischoppy.

It is easy to slip when using ship ladders to places likethe engine room. Be especially careful when carryingtools.

Follow instructions of authorized personnel beforetransporting heavy items.

For inboard work, be sure to carry a flashlight in yourpocket. If a power failure occurs, you will be able towatch your step.

(2) Fire prevention on a vessel

When using open flames, keep a fire extinguisherhandy.

A fire in the vicinity of an oil tanker or petrochemicalcomplex may result in a major disaster.

Do not use welding equipment or smoke in any placesother than those designated.

After using open flames, confirm with the chief engineengineer (or engine engineer) that clean up was thor-ough, and there is no danger of fire.

Operate the machine in the presence of the chiefengine engineer (or engine engineer).

9. Past disasters

The narratives in the following section are all true sto-

ries. Even valuable lessons learned in compensation

for disasters all become sheer nonsense, once theirendings have been known.

There is the Heinrich's famous law of 1:29:300.

According to this law, one disaster has 29 minor inju-

ries and 300 hazardous actions resulting in injuries.

There are many disaster factors hidden around us.

With the "Safety Tips for Service Engineers" in mind,draw lessons from past disasters and gain mastery of

them.

Note:

Sources of past disasters: Newspapers, literatures, service

engineers, Safety News, and other resources.

An explosionoccurred when aworker at a com-pany lit a lighter inthe vicinity of a

storage tankimmediately afterthe tank had beenpainted. Theexplosion killedthe worker.

At a refrigerationplant, a nearbywelding flameignited a gasoline-rinsing tank to

cause a suddenexplosion. Work-ers in the vicinityof the tank gotburned.

A worker ignited amatch on board avessel unaware of anoxygen leak from

welding. The matchcaused the oxygen toignite and resulted inan explosion thatkilled the worker.

Gas leakage from arefrigeration unit inthe basementmachine room of asupermarket suffo-cated and killed a

security guard takinga nap.

In a department

store, a burning ciga-rette thrown by a sitemanager caused afire and resulted in adisaster killing 118people.

While performingductwork, the ductmaterial came intocontact with electri-cal wires, causing

electric shocks andresulting in the seri-ous injuries of threepeople.

One co-workerturned a switch ONduring the inspectionof an air-cooled con-

denser withoutchecking with theother worker. The fanstarted and hit theother worker on thehead, killing theworker.

During airtight workon board a vessel, anitrogen gas cylindertoppled over to kill aworker.

A worker lifted up hishead in the tight con-

fines of a machineroom and hit an over-head pipe with head,causing a lacerationto his scalp.

An employee triedusing a stepladderthat was too shortand lost his footing.

The fall from the step-ladder caused him tobreak a bone.

Case Examples I(Injuries requiring treatment)

A worker sat down in front of ablackboard and worked. Whenanother worker tried to move the

blackboard, the blackboard over-

turned and a corner hit the worker

on the head, resulting in an accident

that put eight stitches in the head of

the sitting worker.

Accident involving an injury requiring five stitches inthe back of the right hand:

While servicing a model SH5LE unit, the worker

unfastened the foot bolt with a spanner. In the course

of removing the foot bolt for the compressor replace-ment, the worker banged his right hand hard on a

part sticking up from the bottom frame.

Fracture of left radius forearm, cracked ribs on the right side,and contusions of the left region of the head, left shoulder,

and right chest (hospitalization):*A worker was coming downa ladder after an on-site inspection of an outdoor unit on a

rooftop. The ladder slid out from underneath, causing the

worker to fall with the ladder.

This worker was

not wearing a hard

hat, and the bor-

rowed ladder wasleaning too far on a

slippery surface.


33/125

30

Contusion of the pelvis*A worker sat on the

top rung of a step-

ladder fasteningbolts (36 mm) to fix

the motor of a screw

refrigeration unit

using a double-

ended spanner (with

a pipe added forleverage). Some-

thing, either the spanner from the bolt or the

extension pipe from the spanner, suddenly

came free and caused the worker to fall hard off

the stepladder.

Laceration to the back of left hand requiring sixstitches

A worker stood on a 1-m

high platform for the

snow protection hood of

a 120-HP air cooler

chiller (in the field

assembly process) to

mount sprays. The heel

of his safety shoes got

stuck in an angle, and he

lost his balance. As he was falling from the plat-

form, he tried to grab the angle with his left

hand, and he cut himself on the stainless steel

cover, causing a laceration between the left

thumb and index finger.

Safety precautions for use of stepladder Place the stepladder in a stable place.

(Place nothing around the stepladder.) Securely apply the stoppers. Set the angle of legs to 75 or less and

securely apply the stoppers. The foothold should have a proper width.


34/125

31

Case Examples II(Minor injuries)

While disassembling a machine, a worker care-lessly touched the fin with his hand injuring hisfingers.

While cutting welding material, the material

bounced back and cut the worker.

Workers caught their fingers in the fittingbetween the upper and lower tiers of a double

tier toolbox. However, there was no major injury,

and they only felt pain in the fingers.

While an air conditioner was running, a workertouched the discharge pipe to suffer minor

burns.

While installing a unit, a worker cut his fingerwith a knife in the course of stripping electricalwires and had to put a bandage on his finger.

While a worker was usinga pipe expansion tool, he

tried to hold the front endof the drill with his hand.

The worker worked with

caution but put his hand

up by a reflex action. At

that time, someone next

to the worker knocked offthe hand to prevent an

injury.

3. Service Engineer Self-evaluationForm

Operation standards for service engineer self-evaluation form

Objectives: z Upgrade customer service and safety awareness

of service engineers, by implementing a hazard

prevention program for a local representative.

z Define action guidelines for service engineers to

minimize errors in judgment and actions.

Target: All service engineers (company members, cooper-

ative company workers, and trainees)

Implementation procedure:

Service engineers present the self-evaluation

forms to the service station representative on a

regular basis (12 forms/head/year).

The service station representative fills out the sta-

tus on the self-evaluation form in and, at the

same time, writes any items worthy of special

mention about the service engineer on the self-

evaluation form.

The service station representative presents copies

of the self-evaluation forms and to the

Administration once a month.

If there are any problems with the work of the ser-

vice engineer, the service station representative

provides on-the-job training for him and records

the results of the training to the self-evaluation

form and keeps a record of it. (The representa-

tive adds records as needed and uses them for

training material.)

Check: z Make monthly reports on the results at the meet-ing.
