12. Always be alert to potential hazards in your work-
ing
environment
(that
is,
damp
floors,
nongrounded extension cords, power surges, miss-
ing safety grounds, and so on).
13. Do not touch live electrical circuits with the
surface of plastic dental mirrors. The surface of
the dental mirror is conductive and can result in
machine damage and personal injury.
14. Four steps should be taken in the eventof an elec-
trical accident:
a.
USE CAUTION-DON'T BE A VICTIM
YOURSELF.
b.
TURN POWER OFF.
c.
HAVE SOMEONE ELSE GET MEDICAL
HELP.
d.
ADMINISTER RESCUE BREATHING IF
VICTIM IS NOT BREATHING.
15. Do not use solvents, cleaners, or oils that have not
been approved by IBM.
16. Lift by standing or pushing up with strong leg
muscles.
This takes the strain off the back
muscles. Do not lift any equipment or parts that
you feel uncomfortable with.
17. Each Customer Service Representative (CSR) is
responsible to be certain that no action on his/her
part renders the product unsafe or exposes
hazards to customer personnel.
18. Place
removed machine covers in a safe,
out-of -the-way
location
while
servicing
the
machine. These covers must be placed on the
machine before the machine is returned to the
customer.
19. Always place your tool kit away from a walk area
(such as under a desk or table) where no one can
trip over it.
20. Avoid wearing loose clothing that may be caught
in machinery. Shirt sleeves must be left buttoned
or rolled up above the elbow. Long hair and
scarves must be secured.
21. Ties must be tucked in shirt or have a tie clasp
(preferably nonconductive) about 3 inches from
the end when servicing a machine.
22. Before starting equipment, make sure that fellow
CSRs and customer personnel are not in a
hazardous position.
23. Maintain good housekeeping in the area of the
machines while performing and after completing
maintenance.

24. Avoid touching moving mechanical parts when
lubricating, checking for play, and so on.
Prevention
is the key to electrical safety. You should
always be conscious of electrical safety and practice
good habits,
as follows:
•
Make certain that the customer's power receptacle
meets IBM equipment requirements.
•
Inspect line cords and plugs. Check for loose,
damaged, or worn parts.
•
•
Before removing a component, which can retain a
charge from the machine, review the procedure in
the maintenance documentation.
Wear safety
glasses and CAREFULLY discharge the neces-
sary components exactly as directed by the service
procedure.
Do not use an ordinary lamp as an extension trou-
ble light.
Never assume anything about a machine or circuit. No
machine is completely safe all the time. The exact
condition of a machine may be unknown. Here are
some of the reasons why:
The power receptacle could be incorrectly wired.
•
Safety devices or features could be missing or
defective.
•
The maintenance and/or modification history may
be uncertain or unclear.
•
•
•
•
•
•
A possible design deficiency could exist.
The machine may have suffered transportation
damage.
The machine may have an unsafe alteration or
attachment.
An engineering change (EC) or sales change may
have been improperly installed.
The machine may have deteriorated due to age or
environmental extremes.
A cOlll:ponent could be defective, creating a
hazard.
•
Some component of the machine may have been
incorrectly assembled.
Relating to safety, these are some of the ways the
condition of the machine can be affected. Before you
begin a service call or procedure, exercise good judgment
and proceed with caution.
