2.3.3.
Protection against dangerous body contact currents
In stationary battery installations, measures must be taken to guard against direct and
indirect contact. For battery installations this protection can take the form of obstacles or
distance.
According to DIN EN IEC 62485-2:
Battery installations with a rated voltage of 60
V … 120 V must be accommodated in
electrical operation areas.
Battery installations with a rated voltage of more than 120 V must be accommodated in
enclosed, electrical operating areas.
Doors of battery rooms and cubicles count as obstacles when they are identified by the
following warning plates (fitted externally):
Warning plate “Dangerous Voltage”, if the battery voltage exceeds 60 V (see ISO 3864)
Prohibition sign: “No fire, naked flame or smoking”
Warning plate “Battery Room” to indicate electrolyte, explosive gases, dangerous
voltages and currents.
2.3.4.
Special hazards in the event of fire
Danger!
Wear personal protective equipment against alkaline solutions
, for large battery systems also use breathing protection with self-
sufficient breathing air supply.
Disconnect battery electrically.
Extinguish incipient fires with CO2.
When extinguishing electric fires with water in low-voltage systems (up to 1 kV), maintain a
spray distance of 1 m and a full spray distance of 5 m.
Wear alkali-resistant protective clothing! In case of contact with water, there is a risk of
reactions with the electrolyte (caustic solution) and consequently of violent spraying.
Extinguish in short intervals. Otherwise, there is danger of explosion due to possible static
charging on the battery housing.
Failure to do so may result in death or serious injury.
