Safety Inspection Guide
The intent of this inspection guide is to assist you in identifying
potentially unsafe conditions related to card maintenance. Good
judgment should be used to identify potential safety hazards not
covered by this inspection guide.
If any unsafe conditions are present, a determination must be made
about how serious the apparent hazard can be and whether you can
continue without first correcting the problem.
Consider these conditions and the safety hazards they present:
Electrical hazards, especially primary power: Primary voltage on
the frame can cause serious or fatal electrical shock.
Explosive hazards: A damaged CRT face or capacitor can cause
serious injury.
Mechanical hazards: Loose or missing hardware can cause
serious injury.
The guide consists of a series of checks.
1. Set the power switches for all personal computer components to
off.
2. Disconnect all power cords from the power receptacles.
3. Check exterior covers for damage (loose, broken, or sharp
edges).
