There are four classes of rubber insulating gloves,
the primary features being the wall thickness of the
gloves and their maximum safe voltage rating. The
classes and the maximum safe voltage for which the
gloves can be used are listed in table 3-2.
Class 0 gloves are available in half-sizes from size
9 through size 12.
SAFETY SHORTING PROBE
Some of the electronic equipment youll work on
will use large capacitors to filter the electrical power.
You must discharge these capacitors before you can
begin any work on the equipment. To do this you will
need to get a safety shorting probe and follow these
1. Make sure input power to the equipment has
been secured. Use the appropriate tag-out procedures, if
2. Open the equipment to gain access to the
capacitors that need to be discharged. BE CAREFUL
not to touch any exposed terminals. Large filter
capacitors can store a lot of energy. And if you touch the
exposed terminals. . . .ZAP!!
3. Connect the flexible ground strap of the safety
shorting probe to the metal chassis of the equipment.
Make sure there is a good metal-to-metal connection.
4. While holding the safety shorting probe by its
plastic handle, touch the metal probe tip to the
appropriate terminals to be grounded. BE CAREFUL
not to touch the metal probe tip or the flexible ground
strap while the probe is in contact with the terminals of
the capacitor. Repeat this step two or three times to
ensure the capacitor is completely discharged.
Approved safety shorting probes are stocked by the
Naval Stock System.
As an Electronics Technician, you depend heavily
on your sense of sight in performing your job. To help
protect your eyesight, you should know (1) when to
wear eye protection, and (2) which eye protection to
The Navy Occupational Safety and Health
(NAVOSH) Program Manual (OPNAVINST 5100.23),
states that you are required to wear appropriate eye
protective equipment when performing eye
hazardous operations. In other words, whenever
youre doing something that could damage your eyes,
WEAR EYE PROTECTION. Some of the things
youll do that fall into this category are:
Using an electric drill
Cleaning and maintaining equipment using haz-
Here are a few things to remember about eye
Eye protection isnt an option; its a requirement.
If youre doing something that calls for eye protection,
take the time to get it and wear it. You can replace a
scratched pair of goggles, but you cant replace a
Wear eye protection even when you are just
walking around hazardous activities.
After you are through using eye protection
equipment, clean it and store it properly.
Hearing loss is a problem in the Navy. Every day,
youll be working with and around many noisy
equipments and machinery that could damage your
hearing. And, in most cases, the damage wont happen
overnight; it will happen slowly. Your hearing will
degrade until you will not be able to hear the softer
sounds as well as you could have if youd worn hearing
protection. This is commonly called a hearing
threshold shift. It simply means that the more you are
exposed to damaging levels of noise, the louder normal
sounds must be for you to hear them.
You must start NOW to protect yourself from
hearing loss. OPNAVINST 5100.23 states that
hearing protective devices shall be worn by all
personnel when they must enter or work in an area
where the operations generate noise levels of greater
than 84 decibels.
Recall from chapter 2 the discussion of hazardous
paints, solvents, and other materials associated with the
cleaning and maintenance of electronic equipment and
antennas. We cannot emphasize too strongly the
importance of using the proper respiratory protection
