CE SAFETY PRACTICES
All Customer Engineers are expected to take every safety
precaution possible and observe the following safety practices
while maintaining IBM equipment:
1.
You should not work alone under hazardous conditions
or around equipment with dangerous voltage. Always
advise your manager if you MUST work alone.
2.
Remove all power, ac and dc, when removing or
assembling major components, working in immediate
areas of power supplies, performing mechanical
inspection of power supplies, or installing changes in
machine circuitry.
3. After turning off wall box power switch, lock it in the
Off position or tag it with a "Do Not Operate" tag,
Form 229-1266. Pull power supply cord whenever
possible.
4.
5.
6.
7.
When it is absolutely necessary to work on equipment
having exposed operating mechanical parts or exposed
live electrical circuitry anywhere in the machine, observe
the following precautions:
a. Another person familiar with power off controls
must be in immediate vicinity.
b .. Do not wear rings, wrist watches, chains, bracelets,
or metal cuff links.
c. Use only insulated pliers and screwdrivers.
d. Keep one hand in pocket.
e. When using test instruments, be certain that controls
are set correctly and that insulated probes of proper
capacity are used.
f. Avoid contacting ground potential (metal floor strips,
machine frames, etc.). Use suitable rubber mats,
purchased locally if necessary.
Wear safety glasses when:
a. Using a hammer to drive pins, riveting, staking, etc.
b. Power or hand drilling, reaming, grinding, etc.
c. Using spring hooks, attaching springs.
d. Soldering, wire cutting, removing steel bands.
e. Cleaning parts with solvents, sprays, cleaners,
chemicals, etc.
f. Performing any other work that may be hazardous to
your eyes. REMEMBER-THEY ARE YOUR EYES.
Follow special safety instructions when performing
specialized tasks, such as handling cathode ray tubes
and extremely high Voltages. These instructions are
outlined in CEMs and the safety portion of the
maintenance manuals.
Do not use solvents, chemicals, greases, or oils that
have not been approved by IBM.
8. Avoid using tools or test equipment that have not been
approved by IBM.
9. Replace worn or broken tools and test equipment.
10. Lift by standing or pushing up with stronger leg
muscles-this takes strain off back muscles. Do not lift
any equipment or parts weighing over 60 pounds.
11. After maintenance, restore all safety devices, such as
guards, shields, signs, and grounding wires.
12. Each Customer Engineer is responsible to be certain that
no action on his part renders products unsafe or
exposes customer personnel to hazards.
13. Place removed machine covers in a safe out-of-the-way
place where no one can trip over them.
14. Ensure that all machine covers are in place before
returning machine to customer.
15. Always place CE tool kit away from walk areas where
no one can trip over it; for example, under desk or table.
16. Avoid touching moving mechanical parts when
lubricating, checking for play, etc.
17. When using stroboscope, do not touch ANYTHING-it
may be moving.
18. Avoid wearing loose clothing that may be caught in
machinery. Shirt sleeves must be left buttoned or roiled
above the elbow.
19. Ties must be tucked in shirt or have a tie clasp
(preferably nonconductive) approximately
3
inches from
end. Tie chains are not recommended.
20. Before starting equipment, make certain fellow CEs and
customer personnel are not in a hazardous position.
21. Maintain good housekeeping in area of machine while
performing and after completing maintenance.
Knowing safety rules is not enough.
An unsafe act will inevitably lead to an accident.
Use good judgment-eliminate unsafe acts.
ARTIFICIAL RESPIRATION
General Considerations
1. Start Immediately-Seconds Count
Do not move victim unless absolutely necessary to
remove from danger. Do not wait or look for help or
stop to loosen clothing, warm the victim, or apply
stimulants.
2. Check Mouth for Obstructions
Remove foreign objects. Pull tongue forward.
3. Loosen Clothing-Keep Victim Warm
Take care of these items after victim is breathing by
himself or when help is available.
4. Remain in Position
After victim revives, be ready to resume respiration if
necessary.
5. Call a Doctor
Have someone summon medical aid.
6. Don't Give Up
Continue without interruption until victim is breathing
without help or is certainly dead.
Rescue Breathing for Adults
1. Place victim on his back immediately.
2. Clear throat of water, food, or foreign matter.
3. Tilt head back to open air passage.
4.
5.
6.
7.
8.
9.
Lift jaw up to keep tongue out of air passage.
Pinch nostrils to prevent air leakage when 'You blow.
Blow until you see chest rise.
Remove your lips and allow lungs to empty.
Listen for snoring and gurglings-signs of throat
obstruction.
Repeat mouth to mouth breathing 10-20 times -a minute.
Continue rescue breathing until victim breathes for
himself.
