Safety Precautions
Radio and radar devices are operated by high voltages of anywhere from a few hundred volts up
to many hundreds of thousands of volts.
Observe the following precautions to prevent the risk of electric shock.
Avoid contact with the internal parts of these devices.
Only specialized service people should do any maintenance, inspections, or adjustments inside
the devices.
Falling after receiving an electric shock may lead to extensive secondary injuries, so be sure you
have a safe place to stand when working.
In the event that someone receives an electric shock, immediately implement emergency
procedures, such as cardiopulmonary resuscitation.
If you must reach into a device, as in the case of an emergency, you must switch off the devices
and ground a terminal in order to discharge the capacitors. After making certain that all the
electricity is discharged, only then can you insert your hand into the device. Wearing dry cotton
work gloves is another way to reduce risks. One more necessary precaution is to not use both
hands at the same time.
Although there is no danger with normal use, it is very dangerous if contact is made accidently
with the internal parts of these devices. There is a very high risk of death by high voltages of tens
of thousands of volts. In some cases, you could be fatally electrocuted by voltages of several
hundred volts.
If you find an electrocution victim, you must first switch off the machinery that caused the
electrocution and ground all circuits.
If you are unable to immediately cut off the circuit, do not directly touch the victim. Quickly use a
non-conductive material, such as a dry board or cloth, to move the victim away from the device.
If someone receives an electric shock, immediately implement emergency procedures, such as
cardiopulmonary resuscitation.
When a person is electrocuted, the current passes through their heart and may cause ventricular
fibrillation or cardiac arrest. Also, if the shock is mild, the victim's breathing may be restored by
doing artificial respiration. An electrocution victim becomes very pale, their pulse can be very
weak or even stop, and they may lose consciousness and become stiff.
