1.0 SAFETY SUMMARY
1.1 General Safety Precautions
The following are general safety precautions and instructions that personnel must understand
and apply during many phases of operation and maintenance to ensure personnel safety and
health and the protection of property. Portions of this information may be repeated in certain
chapters of this publication for emphasis.
WARNING AND CAUTION STATEMENTS
WARNING AND CAUTION statements have been strategically placed in the text to emphasize
certain steps or procedures for the protection of personnel (WARNING) or equipment
(CAUTION). A WARNING or CAUTION once provided should apply each time the related
step is repeated, regardless of the number of times the WARNING or CAUTION is repeated
throughout the text. Prior to starting any task, the WARNINGS or CAUTIONS included in the
text for that task should be reviewed and understood.
KEEP AWAY FROM LIVE CIRCUITS
Operating personnel must at all times observe safety regulations. Do not replace components or
make adjustments inside the equipment with the 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 injuries, always remove power from, discharge, and
ground a circuit before touching it. Adhere to all lock out/tag out requirements.
DO NOT SERVICE OR ADJUST ALONE
Do not attempt internal service or adjustment unless another person capable of rendering aid
and resuscitation is present.
RESUSCITATION
Personnel working with or near dangerous voltage shall be trained in modern methods of
resuscitation.
COMPRESSED AIR
Use of compressed air for cleaning can create an environment of propelled foreign particles.
Air pressure shall be reduced to less than 30 psi and used with effective chip guarding and
personnel protective equipment.
