APPENDIX E
E.1. General Safety Requirements
SAFETY AND PRECAUTION SUMMARY
The following are general safety precautions that are not related to any specific
procedures and therefore do not appear elsewhere in this publication. These are
recommended precautions that personnel must understand and apply during many phases of
operation and maintenance.
Keep away from live circuits
Maintenance personnel must at all times observe all safety regulations. Do not replace
components or make adjustments inside the equipment with the high voltage supply turned on.
Under certain conditions, dangerous potentials may exist when the power control is in the off
position due to charges retained by capacitors. To avoid casualties, always remove power and
discharge and ground the circuit before touching it.
Do not service or adjust alone
Under no circumstances should any person reach into or enter an enclosure for the purpose of
servicing or adjusting the equipment except in the presence of someone who is capable of
rendering aid.
Resuscitation
Personnel working with or near high voltage should be familiar with modern methods of CPR.
Such information may be obtained from the local Medical Aid Association. This knowledge may
save a life.
Do not wear jewelry
Personnel performing maintenance on equipment are not to wear watches, rings,
necklaces, bracelets or other jewelry at any time. Electrical arcing can occur when metallic
objects are in the proximity of voltage potentials. Jewelry can become entangled or otherwise
restrict movement causing severe personal injury.
Electrical/Electronic (General)
Voltages used in this equipment can cause arcing and may result in severe burns. Avoid contact
and remove rings, watches, and other jewelry, which may cause personal injury from electrical
shock.
