CE SAFETY PRACTICES
All Customer Engineers are expected to take every safety
precaution possible and observe the following safety prac-
tices while maintaining I BM 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 assem-
bling major components, working in immediate areas of
power supplies, performing mechanical inspection of pow-
er 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. When it is absolutely necessary to work on equipment
having exposed op'eraJing 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.
I.
Use suitable rubber mats, pur-
chased locally if necessary.
5. 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, chemi-
cals, etc.
f. Performing any other work that may be hazardous to
your eyes. REMEMBER - THEY ARE YOUR EYES.
6. Follow special safety instructions when performing special-
ized 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.
7. 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 ap-
proved by IBM.
9. Replace worn or broken tools and test equipment.
10. Lift by standing or pushing up with stronger leg muscles-
thi') takes strain off back muscles. Do not lift any equip-
ment 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 ma-
chinery. Shirt sleeves must be left buttoned or rolled 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 per-
forming 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 him-
self 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. Lift jaw up to keep tongue out of air passage.
5. Pinch nostrils to prevent air leakage when you blow.
6. Blow until you see chest rise.
7. Remove your lips and allow lungs to empty.
8. Listen for snoring and gurglings - signs of throat obstruc-
tion.
9. Repeat mouth to mouth breathing 10-20 times a minute.
Continue rescue breathing until victim breathes for himself.
