WARNING
Electrical high voltage cannot be seen, but it can kill
you. Electricity is unlike most other dangerous
things you can come in contact with because it gives
no warning and no symptoms to be wary of. Its effect
is immediate. It can kill you, render you
unconscious, or severely burn you. To ensure your
safety and that of other maintenance personnel,
always observe the following precautions:
DO NOT perform any maintenance on electrical
equipment unless all power is removed.
ALWAYS place POWER OFF warning tags on power
supply switches so that no one will apply power
while you are performing maintenance.
FOR ARTIFICIAL RESPIRATION, REFER TO FM 21-11.
