2.1.2.
Electrical voltage
Metal parts of the batteries are always live. High currents flow in the event of a short circuit.
There is danger from:
•
Voltages
•
Electric shocks
There is an immediate, high risk situation which, if not avoided, will result in death or serious
injury.
Measures to avert the danger:
•
Be very careful when working on the batteries.
•
Never place tools or other metal objects on a battery.
•
Take off watches and jewellery before working on the batteries.
•
Do not touch bare battery parts, connectors and terminals.
2.1.3.
Electrolyte
Rail. power blocks / cells contain sulphuric acid as electrolyte. The individual cells consist of
grid structure electrodes. Each positive electrode is wrapped in a fleece. The electrolyte is
fixed in this fleece.
•
Electrolyte may leak if the housing of a block/cell is damaged.
•
Reversed polarity of the battery or of individual cells can cause overheating and thus
leakage of electrolyte.
•
Electrolyte is very corrosive.
•
During normal operation contact with the electrolyte is excluded.
•
If the housing is destroyed, the released bound electrolyte is just as corrosive as liquid
electrolyte.
•
The electrolyte can cause severe skin burns and serious eye damage.
There is a potentially hazardous medium-risk situation which, if not avoided, could result in
death or serious injury.
Measures to avert danger:
•
Always wear protective goggles and gloves when working on batteries.
•
Clothes contaminated with electrolyte should be washed with water.
•
Check correct polarity before making connections.
