CE SAFETY PRACTICES
All Customer Engineers are expected to take every safety pre-
caution 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 assem-
bling maier components, 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 necessary to work on 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 familiar with power off controls must
be in immediate vicinity.
b. Rings, wrist watches, chains, bracelets, metal cuff links,
shall not be worn.
c. Only insulated pliers and screwdrivers 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 floor strips,
machine frames, etc. - use suitable rubber mats pur-
chased locally if necessary).
5. Safety Glasses must be worn when:
a. Using a hammer to 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, using solvents, sprays, cleaners, chemicals,
etc.
f. All other conditions that may be hazardous to your
eyes. REMEMBER, THEY ARE YOUR EYES.
6. Special safety instructions such as handling Cathode Ray
Tubes and extreme high voltages, must be followed as
o.utlined 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.
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 equip-
ment or parts weighing over 60 pounds.
11. All safety devices such as guards, shields, signs, ground
wires, etc. shall 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
