OPERATIONAL AND MAINTENANCE SAFETY GUIDELINES
Good safety discipline is critical to prevent injury to personnel. All other safety measures are useless if personnel
do not observe the safety precautions and do not follow safety disciplines. Once aware of a hazard, personnel should
ensure that all other personnel are aware of the hazard. The following basic safety disciplines are stressed:
a.
Read a procedure entirely before performing it. Personnel must always perform each assigned task in a
safe manner.
b.
Prior to applying equipment power after maintenance, personnel must ensure that all unsecured hand
tools and test equipment are disconnected from the serviced/maintained equipment and properly stored.
c.
Power to the equipment must be removed before a piece of equipment is removed.
d.
Extreme care must be used when adjusting or working on operating equipment. Voltages in excess of
70 V or current sources in excess of 25 A are covered with barriers. Barriers include warning
information about the hazard encountered upon barrier removal.
SAFETY SUMMARY
Used to alert personnel to a condition that requires emphasis
Hazardous voltage and current levels may exist throughout the equipment. Contact
with these hazards could cause electrocution, electrical shock, burns, or injury due
to involuntary reflexes of the body.
Burn hazards may exist in the equipment that could cause personal injuries and/or
serious equipment damage. Internal surfaces of the equipment may be in excess of
65°C, the point at which personnel could be burned. Extreme caution should be used
when working with any hot assemblies (for example, power supply or power
amplifier assemblies). Physical injury or damage may result to personnel and/or
equipment as a result of a reflex action to a burn.
Overexposure to electromagnetic radiation from amplified radio frequencies
may produce a health hazard.
