Locate the emergency power-off switch for the room in which you are working. Then, if an electrical
accident occurs, you can act quickly to turn off the power.
Disconnect all power by removing the fuses from the fuse and alarm panel before:
Installing or removing a chassis
–
Working near power supplies
–
Do not work alone if potentially hazardous conditions exist.
Never assume that power is disconnected from a circuit; always check the circuit.
Look carefully for possible hazards in your work area, such as moist floors, ungrounded power
extension cables, frayed power cords, and missing safety grounds.
If an electrical accident occurs, proceed as follows:
Use caution; do not become a victim yourself.
–
– Turn off power to the system.
– If possible, send another person to get medical aid. Otherwise, assess the condition of the victim
and then call for help.
– Determine if the person needs rescue breathing or external cardiac compressions; then, take
appropriate action.
