PRECAUTIONS BEFORE OPERATION
Cautions for high voltage
High voltages from hundreds volts to tens of thousands volts are to be applied to the
electronic equipment such radio and radar devices. You do not face any danger during
normal operation, but sufficient cares are required for maintenance, inspection and
adjustment of their internal components. (Maintenance, check-up and adjustment of the
inside of the equipment are prohibited except by maintenance specialists.)
High voltages of tens of thousands volts are so dangerous as to bring a death from
electric shock, but even voltages of hundred volts may sometimes lead to a death from
electric shock. To prevent such an accident, make it a rule to turn off the power switch,
discharge capacitors with a wire surely earthed on an end make sure that internal parts
are no longer charged before you touch any parts inside these devices. At the time,
wearing dry cotton gloves ensures you further to prevent such danger. It is also a
necessary caution to put one of your hands in the pocket and not to use your both hands
at the same time.
It is also important to select a stable foothold always to prevent additional injuries once
you were shocked by electricity. If you were injured from electric shock, disinfect the
burn sufficiently and get it taken care of promptly.
What to do in case of electric shock
When finding a victim of electric shock, turn off the power source and earth the circuit
immediately. If it is impossible to turn off the circuit, move the victim away promptly
using insulators such as dry wood plate and cloth without touching the victim directly.
In case of electric shock, breathing may stop suddenly if current flows to the respiration
center in the brain. If the shock is not so strong, artificial respiration may recover
breathing. When shocked by electricity, the victim will come to look very bad with weak
pulse or without beating, resulting in unconsciousness and rigidity. In this case, it is
necessary to perform an emergency measure immediately.
