so that personnel do not expose themselves unneces-
sarily to injury or occupational health hazards. Most
accidents can be prevented if personnel are alert to
causes and take appropriate remedial action.

Electrical Safety Education
Electrical Safety Training
Any failure to follow electrical safety rules or pro-
cedures may result in mild to severe shocks. In some
cases, death may even result. As a leading FC, you
have safety-related responsibilities that may be
grouped into the following three general areas:
1. Division Responsibilities: Division responsibili-
ties include ensuring that all personnel in the division
are aware of and observe all safety precautions, espe-
cially those precautions regarding electrical safety.
2. Nonelectrical Rating Responsibilities: Nonelec-
trical rating responsibilities are ever increasing, as
more and more electronic equipment is used in the
various jobs. As an FC1 or FCC, you will automati-
cally be considered an expert on electrical safety pre-
cautions. Therefore, you have a responsibility to
educate the personnel whose primary duties are non-
electrical about these precautions.
3. Petty Officer Responsibilities: As a petty of-
ficer, you have the same responsibilities as all other
petty officers in enforcing all safety precautions.
Electrical safety education is a must. You cannot
expect personnel to observe a safety precaution unless
they are fully aware of the dangers involved. There-
fore, one of your first duties is to ensure that all per-
sonnel in the combat systems/weapons division are
aware of the dangers and the safety precautions neces-
sary to combat those dangers.
Safety precautions depend to some extent on the
type of ship involved. Some ships necessarily have
particular precautions that must be strictly observed,
but which are not applicable to other types of ships.
Therefore, you should ensure that all personnel read
and understand all safety precautions pertaining to the
electrical and electronic equipments on your own ship.
Safety precautions for personnel in nonelectrical
ratings should include information concerning elec-
trical shock and precautions they must observe when
using electrical equipment, either aboard ship or
Facts to be stressed to all personnel, both electrical
and nonelectrical rating personnel, concerning electric
shock should include the following cautions:
Electrical Shock Causes
Voltages as low as 30 volts can be fatal.
Nearly all shipboard electrical shocks are caused
in one or more of the following ways (all these
failures may be summarized as neglecting applicable
Unauthorized use of, or unauthorized modifi-
cations to, equipment.
Failure to observe applicable safety precau-
tions in the use of equipment or in working on or near
Failure to repair equipment that is known to
be defective and has previously given users a mild
The dangers from electric shock are much
greater aboard ship than ashore.
There is little middle ground between a slight
tingle and a fatal shock.
Fundamentally, current, rather than voltage, is the
criterion of shock intensity. The passage of even a
very small current through a vital part of the human
body may cause death. The voltage necessary to pro-
duce the fatal current depends on such factors as the
body resistance, the contact condition, and the path
the current takes through the body.
