Safety instructions
Observe the following safety instructions when handling the batteries and their components.
2.1.
Potential hazards
2.1.1.
Explosive gas mixture
Each time the batteries are charged, water is decomposed. This can form a hydrogen-
oxygen gas mixture (oxyhydrogen gas), which explodes even at low energy input.
There is danger through:
•
Explosions
•
Fires
•
Blast waves
•
Hot or molten substances flying around
These hazards may be caused by the following ignition sources:
•
Short circuits
•
Electrostatic charges and discharges
•
Smoking
•
Open flames / fire, embers and sparks near batteries
•
Electrical sparks through switches or fuses
•
Hot surfaces with temperatures above 300 °C
There is an immediate, high risk situation which, if not avoided, will result in death or serious
injury.
Measures to avert the danger:
•
Work with insulated, non-sparking tools.
•
Ensure sufficient ventilation of the battery room in accordance with DIN EN IEC 62485-2
so that the potentially explosive gas mixture is removed.
•
Avoid electrostatic charging:
- Do not rub batteries with plastic housings with a dry cloth or a cloth made of synthetic
material!
- Only clean batteries with a cotton cloth moistened with water. Wiping with a cotton cloth
moistened with water does not generate any electrical charge.
- Wipe batteries damp (with water) before removing or tearing off a label.
- Wear shoes and clothing which, due to their special surface resistance, prevent the
formation of electrostatic charges. (see
2.2 Personal protective equipment on page 13)
•
Use hand lamps with mains cable without switch (protection class II) or hand lamps with
battery (protection class IP54).
