WARNING
♦ Untrained personal e.g. apprentices, trainees etc. may
only work on batteries when supervised by a vehicle me‐
chanic/foreman or vehicle electrician/foreman.

acid burns if personal do not handle batteries correctly.
Therefore suitable measures must be taken to ensure that
equipment/solutions etc. are available to neutralize acid
burns. A suitable solution is: e.g. a soap solution.
♦ If electrolyte leaks from a battery it may cause skin burns
and acid corrosion, rusting on the vehicle. This may dam‐
age safety relevant components on the vehicle.
♦ The gas which forms when charging and the gas which
may escape through vent valves is explosive. In extreme
cases a battery may explode if the battery is not handled
correctly.

cutting operations and use naked lights in the vicinity of
batteries. Smoking is also prohibited. Sparks must also
prevented through electrostatic discharge, therefore al‐
ways earth through vehicle body etc. before touching
battery.
♦ Only work on batteries in well ventilated and suitable
rooms.
