to require hearing protection, err toward the side of
safety. Protect your hearing!
It is very important to use the proper respiratory
protection when you use hazardous paints, solvents,
and other materials associated with cleaning and
maintaining electronic equipment and antennas. Be
sure to ask your supervisor about the need for
respiratory protection whenever you
chip lead- or chromate-based paints while
prime or paint the bases of antennas, or
clean circuits with spray solvents or alcohol.
Whenever you perform these operations, be sure
that the work area has good ventilation. This will help
prevent you from over-inhaling hazardous vapors and
Your working environment should have
deck-insulating material (more commonly called
rubber matting) to protect you and your shipmates
from electric shock. It must be installed wherever work
is done on energized electrical and electronic
equipment. This includes electronic repair shops that
have workbenches for working on electronic
The rubber matting should be rated for use in areas
where the maximum voltage will not exceed 3,000
volts. It must be installed in one continuous run, at least
36 inches wide, and must extend at least 24 inches past
each end of the workbench.
If you must work on energized equipment in an
area where rubber matting is not installed, protect
yourself from electric shock by using a 6-foot piece of
rubber matting as a portable safety deck. When you are
done, roll it up and store it for the next job.
Rubber matting does a great job of protecting you
from electric shock, but it will not protect you for long
if you do not take care of it.
The following tips will help keep the insulating
properties of rubber matting intact:
Keep rubber matting clean and free of any excess
dirt, oil, or oil-based products. When you clean
it, do NOT use abrasive cleaners or electric
buffers; they will ruin its insulating
Inspect the rubber matting for cuts, cracks, or
excessive wear periodically. If you notice any of
these conditions, replace it entirely.

Throughout your training you have been taught
about electrical and electronic safety. This chapter has
attempted to give you an overview of this area of safety.
However, one of the greatest dangers in this area is not
your lack of knowledge but the complacency you may
develop from hearing the same message over and over.
You know these safety standards; they have been
drilled into your thinking. You may have even taught
this material to someone at some time in your career.
DO NOT ALLOW A COMPLACENT ATTITUDE
TO KILL YOU!
Although voltage is normally
mentioned in talks about electrical shock, you must
remember that current is what will kill you. As little as
one-tenth of one ampere (0.1 ampere) of current can be
fatal. The majority of shock fatalities are related to
voltages less than 120 volts. Even lesser voltages can
be fatal because of the relative current flow. Treat all
voltages as life threatening.
In view of the potential harm of electrical shock,
the tag-out system was implemented for your safety.
Do not take anything for granted when tagging out
equipment. Make sure everything is done by the book
and that you and your fellow FCs are safe. Do not be in
such a hurry that you use short cuts in tagging
equipment out or in using protective equipment. Do
not adopt the attitude that its the other guy who gets
killed or injured when using short cuts.

are for tagging out equipment and checking out

apply it to your everyday job.
