Dangers When Working With Batteries

• Personnel instructed in protection, such as a trainee or an apprentice, may only perform work on vehicle Batteries -A- under supervision of technical personnel, for example, a master automotive technician or a master automotive electrician.
• Acid has strong corrosive properties. If Batteries -A- are handled inappropriately, there is a risk that personal injury may result from exposure to harmful electrolyte influences. Therefore, suitable remedies for acid damage must be kept readily available. Soapy water would be a suitable remedy.
• If electrolyte drips out from the Battery -A-, skin can be burned by acid and the vehicle may be affected by acid erosion and corrosion. It is a possibility that safety-related vehicle components can be damaged.
• When charging and when resting after charging, explosive gas is present. In extreme cases, if the Battery -A- is handled inappropriately, the emitted gases may cause the battery to explode.
• Replace a Battery -A- if the visual indicator has >>no color or is bright yellow<<. They may not be tested or charged and jump starting may not be used. There is a risk of explosion during testing, charging or jump starting.
• Producing sparks by sanding, welding, cutting and open flames, (also from smoking near the battery) is forbidden. Producing sparks through electrostatic discharge must also be avoided. Always touch the vehicle body before touching the Battery -A-.
• Only perform Battery -A- procedures in suitable and well-ventilated locations.

Pollution risk 

• Old batteries require special disposal. They contain poisonous lead (Pb) and sulfuric acid.
• Follow disposal requirements, only dispose of used batteries in suitable containers at an authorized collection site.
