Safety Inspection Guide - IBM 6000R - Netfinity - 8682 Hardware Maintenance Manual

— When using testers, set the controls correctly and
use the approved probe leads and accessories for
that tester.
— Stand on suitable rubber mats (obtained locally, if
necessary) to insulate you from grounds such as
metal floor strips and machine frames.
Observe the special safety precautions when you work
with very high voltages; these instructions are in the
safety sections of maintenance information. Use
extreme care when measuring high voltages.
• Regularly inspect and maintain your electrical hand
tools for safe operational condition.
• Do not use worn or broken tools and testers.
• Never assume that power has been disconnected from
a circuit. First, check that it has been powered-off.
• Always look carefully for possible hazards in your work
area. Examples of these hazards are moist floors, non-
grounded power extension cables, power surges, and
missing safety grounds.
• Do not touch live electrical circuits with the reflective
surface of a plastic dental mirror. The surface is con-
ductive; such touching can cause personal injury and
machine damage.
• Do not service the following parts with the power on
when they are removed from their normal operating
places in a machine:
— Power supply units
— Pumps
— Blowers and fans
— Motor generators
and similar units. (This practice ensures correct
grounding of the units.)
• If an electrical accident occurs:
— Use caution; do not become a victim yourself.
— Switch off power.
— Send another person to get medical aid.

Safety inspection guide

The intent of this inspection guide is to assist you in identify-
ing potentially unsafe conditions on these products. Each
machine, as it was designed and built, had required safety
items installed to protect users and service personnel from
injury. This guide addresses only those items. However,
good judgment should be used to identify potential safety
hazards due to attachment of non-IBM features or options
not covered by this inspection guide.
If any unsafe conditions are present, you must determine
how serious the apparent hazard could be and whether you
can continue without first correcting the problem.
Consider these conditions and the safety hazards they
present:
