Intrinsic safety in an electrical accident
The intrinsic safety of the rescuer has absolute priority
in the event of an electrical accident.
The power must be disconnected in
low voltage accidents
by fol-
lowing measures:
n
Switching off
n
Pulling the plug
n
Removing the fuse
n
Turning off the main switch
Firstly separate the injured party from the power source using non-
conductive items and only then rescue them from the hazard zone.
No rescue attempts should be undertaken in
high voltage acci-
dents
because of the intrinsic risk. In the event of high voltage
accidents always immediately initiate the emergency call and
summon specialist safety personnel.
The safety personnel must undertake clearing and securing
according to the five safety rules:
n
Summon qualified electrical staff (for shutdown)
n
Maintain the safety clearance (at least 5m in the case of high
voltage)
n
Switch off the electrical circuit
n
Secure it against being switched on again
n
Have a qualified electrician determine voltage free status
n
Have energized parts nearby covered or isolated by a qualified
electrician
n
Assistance only in consultation with a qualified electrician

tem's hazard zone.
–
Have all activities carried out by qualified personnel
