Upon completion of this lesson, the unit-level communications maintainer will be able to correctly
identify electrical/electronic hazards and take necessary actions to prevent damage to personnel and
a. This subcourse introduces you to electrical/electronic hazards and the minimum safety
precautions with which you, as a unit-level communications maintainer, should be familiar.
b. This subcourse presents minimum safety precautions for all the electrical/electronic hazards
associated with electrical/electronic equipment. It is not the intention of this subcourse to supersede or
delete cautions, warnings, and safety instructions in technical manuals (TMs), technical bulletins (TBs),
or standing operating procedures (SOP).
a. Responsibility. Overall safety is a command responsibility; however, application of safety
principles and practices rests with the supervisor and ultimately with the individual. By observing the
cautions, warnings, and safety instructions in TMs, TBs, and your SOP, you will be able to prevent
personal injury and damage to equipment.
. As a unit-level communications maintainer involved with electrical equipment,
circuits, or transmission (wire) lines, you should be provided local training from qualified personnel in
safety procedures and proper first aid for electrical/electronic hazards. You may need to tell your
commander of the need for annual training for all personnel who work around and directly with electrical
equipment. This training should include, as a minimum, instructions in pertinent aspects of safety and
lifesaving techniques; for example, cardiopulmonary resuscitation (CPR).
c. Standing operating procedures. The supervisor (which may be you) should develop and
post the SOP for all hazardous operations that are performed often. The supervisor should review these
procedures annually for possible changes in the situations and/or work areas.
a. Electrical shock is probably the most common electronic hazard caused by electronic
equipment. As the result of improper grounding of and/or defective equipment, a person's body becomes
a conductor for current to pass through.
(1) Causes. Electrical shock is the result of voltage and current acting upon a person in
contact with an electrical circuit.
