fully. Tag-out procedures are covered in Fire Control-
man, Volume 1, Administration and Safety, NAVED-
TRA 12405.
MAN-ALOFT CHITS.— Man-aloft chits protect
you from RF hazards when you are working on radar
antennas. If the chit is run properly, the operations on
your ship and any ship next to you are modified to
keep you safe. Heed the requirements and follow the
procedures.
EQUIPMENT SAFETY DEVICES.— Devices
built into equipment, such as cut-off switches on
antennas, are for your safety. A cut-off switch, when
set, will keep you out of danger. It will prevent some-
one from rotating the antenna from a remote location.
But, you, the technician, must set the cut-off switch
for it to be of any use. Equipment safety devices are
there for your protection. Use them!
Everywhere you go in the Navy, there will be
communications and radar equipment that produce
electromagnetic radiation environments (EMEs). And,
there will always be electromagnetic radiation hazards
introduced by operating those equipments.
To be safe, you should become familiar with the
hazards associated with your equipment. If you install
new equipment, update your emission control (EM-
CON) bill. Refer to NAVSEA OP 3565, volume I or
II, to determine the hazards associated with specific
equipments.
OTHER RADAR HAZARDS
You cannot always avoid hazards when working
on radars. In these instances, take what precautions
you can and, at least, be prepared for an emergency.
There are various safety concerns associated with
working on energized equipment, going aloft, or han-
dling CRTs. Refer to NAVEDTRA 12405 for more
detailed information on other radar hazards.
Never think about electronics without thinking
about safety. Learn from the safety information you
get from the Ship's Safety Bulletins, Navy mishap
reports, and personal experience. Follow established
procedures and all safety instructions. Live longer.
ENERGIZED EQUIPMENT
You may have to work on energized equipment on
a hectic bridge, in a crowded combat information
center (CIC), or in a cramped radar equipment room.
These are not ideal safety environments. As these
spaces are maintained by various people, always
check the rubber matting around your equipment.
Also check other protective equipment before using
them, such as rubber gloves and shorting probes.
WARNING!
NEVER WORK ALONE ON
ENERGIZED EQUIPMENT.
On ships with minimum manning, you may not
have the option of using another Fire Controlman as
a safety observer. Make sure that whoever is going to
observe you is qualified in cardiopulmonary resus-
citation (CPR). Brief your observer on what you will
be doing. Physically show him where the cut-off
switch is located. Have him standby at a safe distance
with a rope or a wooden
equipment, if necessary.
MAN-ALOFT CHITS

When you work aloft on radar antennas, your
man-aloft chit protects you from the RF radiation
hazards. But, you also need to be protected from
falling.
Perform the maintenance required by the Planned
Maintenance System (PMS) for safety harnesses
every time you use a harness. And remember, even a
good harness can’t save you unless you use it cor-
rectly. When you go up the mast, attach your harness
properly so you can’t free-fall to the deck. Attach a
line to any tools you carry up, so they are unable to
