SAFETY PROCEDURES
Safety cannot be overemphasized. To insure per-
sonal safety and the safety of co-workers, each CE
should make it an everyday practice to observe
safety precautions at all times. All CE's should be
familiar with the general safety practices and pro-
cedures for performing artificial respiration that
resistors to drain off capacitor charges when power
is dropped, it is wise to check all capacitors with a
meter before attempting maintenance. A defective
bleeder resistor could create an unexpected hazard.
are outlined in CE Safety Procedures, S229-1264. For
convenience, this form is duplicated below.
CAUTION
Before changing SLT cards in main storage, storage
protect, and local storage, drop power to the unit.
Dropping power is the only sure way to prevent card
damage from voltage surges during card replacement.
Always use a reliable voltmeter to verify that power
is actually off after using power off switches. Al-
though all power supplies are provided with bleeder
CE SAFETY PRACTICES
All Customer Enginurs are expected to take every safety pre-
caution possible and observe the following safely practices
while maintaining IBM equipment:
I. 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 com·ponenls, working in immediate area of
power supplies, performing mechanical inspection of power
supplies and installing changes in machine circuitry.
3. Wall box power switch when turned off should be locked
or tagged in off position. "Do not Operate" tags, form
229-1266, affixed when applicable. Pull power supply cord
whenever possible.
4. When it is absolutely neceuary to work an equipment hav-
ing exposed operating mechanical parts or exposed live
electrical circuitry anywhere in the machine, the following
precautions must be followed:
a. Another person fomiliar with power off controls must
be in immediate vicinity.
b. Rings, wrist watches, chains, bracelets,. metal cuff link.,
shall not be worn.
c. Only insulated pliers and 5crewdrivers shall be used.
d. Keep one hand in pocket ..
e. When using test instruments be certain controls are set
correctly and proper capacity, insulated probes are used.
f. Avoid contacting ground potential (metal naor strips.
machine frames, etc. - use suitable rubber mats pur-
chased locally if necessary).
5. Safety Glasses must be worn when:
a. Using a hammer lo drive pins, riveting, staking, etc.
b. Power hand drilling, reaming, grinding, etc.
c. Using spring hooks, attaching springs.
d. Soldering, wire cutting, removing steel bands.
e. Parts cleaning, u1ing solvents, sprays, cleaners, chemicals,
etc.
f. All other conditions that may be hazardous lo your
eyes. REMEMBER. THEY ARE YOUR EYES.
6. Special safety instructions such as handling Cathode Ray
Tubes and extreme high voltages, mu•I be followed as
outlined in CEM's and Safety Section of the Maintenance
Manuals.
7. Do not use solvents, chemicals, greases or oils that have
not been approved by IBM.
I. 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 pu•hing up with stronger leg muscles -
this takes strain off back muscles. Do not lift any equip-
ment or parts weighing over 60 pounds.
11. All safety devices such as guards, shields, signs, ground
wires, etc. •hall be restored after maintenance.
KNOWING SAFETY RULES IS NOT ENOUGH
AN UNSAFE ACT WILL INEVITABLY LEAD TO AN ACCIDENT
USE GOOD JUDGMENT - ELIMINATE UNSAFE ACTS
s22g.1264-1
12. Each Customer Engineer is responsible to be certain that
no action on his part renders product unsafe or expo1es
hazards to customer penannel.
13. Place removed machine covers in a safe aut-of·the-way
place where no one con trip over them.
14. All machine covers must be in place before machine is re-
turned to customer.
15. Always place CE tool kit away from walk areas where na
one can trip over it (i.e .. under desk or table).
16. Avoid touching mechanical moving parts (i.e., when lubri·
eating, checking for play, etc.).
17. When using •lrobo5Cope - do not touch ANYTHING - it
may be moving.
18. Avoid wearing loose clothing that may be caught in machin-
ery. Shirt •leeves mu•t be left buttoned or rolled above the
elbow.
19. Ties must be tucked in shirt ar have a tie clasp (preferably
nonconductive) approximately 3 inches from end. Tie chains
are not recommended.
20. Before starting equipment, make certain fellow CE's and
cu•lomer personnel are not in a hazardau• position.
21. Maintain good hou•ekeeping in area af machines while per·
forming and ofter completing maintenance.
Artificial Respiration
GENERAL CONSIDERATIONS
1. Start Immediately, Seconds Count
Do not move victim unless absa·
lutely necessary to remove from
danger. Do not wait or look for
help or •lap to loosen clothing,
warm the victim ar apply stimu-
lanll.
2. Check Mouth f.or obstructions
Remove fare ign objects - Pull
tongue forward.
3. LooHn Clothing - Keep Warm
Take care of these items after vic-
tim is breathing by himself or
when help is available.
4. Remain in Position
After victim revives, be ready to
resume respiration if necessary.
S. Call a Dactor
Have someone summon medical
aid.
6. Don't Give Up
Continue without interruprion until
victim is breathing without help or
is certainly dead.

Rescue Breathing for Adulll
Victim on His !lack Immediately
1. Clear throat of water. food, or
foreign matter.
2. Tilt head back to open air passage.
3. lift jaw up to keep tongue out of
air passage.
4. Pinch nostrils to prevent air leak·
age when you blow.
5. Blow until you see chest rise.
6. Remove your lips and allow lungs
ta empty.
7. listen for snaring and gurglings,
signs of throat obstruction.
I. Repeat mouth to mouth breathin9s
10-20 times a minute.
Continue rescue breathing until he
breathes for himself.
