Lead acid batteries can cause serious injury if not handled correctly. They are capable of delivering an electric charge at a very high rate. Gases released when batteries are charging – hydrogen (very flammable and easily ignited) and oxygen (supports combustion) – can result in an explosion. Show
The acid used as an electrolyte in batteries is also very corrosive and can cause injuries if it comes into contact with workers. Electrolyte that has been spilled can also cause significant damage to property and the environment. Hazards of working with batteries may include:
Risk control measuresSafe handling and storageYou should:
Refer to the manufacturer’s instructions, including the Safety Data Sheet for additional information. Acid electrolyteWhen working with acid electrolyte you should:
Electrolyte spillBefore working with an electrolyte solution, ensure you have access to (and have read) the appropriate Safety Data Sheet (SDS). In the case of a spill, follow the SDS instructions for electrolyte spill containment, clean-up and disposal details. If electrolyte is spilled you should:
Safe chargingWhen charging, you should:
Information, instruction and trainingWorkers should be informed, instructed and trained in:
Personal protective equipmentWorkers must wear:
Consult the SDS for the electrolyte (acid) to determine the correct type of PPE.

These types of burns might not show up right away. It can take several minutes or hours for symptoms to start to appear. Skin irritation, redness, and blackened or dead skin can be symptoms of chemical burns.
Is battery water harmful for skin?Lead acid batteries are usually filled with an electrolyte solution containing sulphuric acid. This is a very corrosive chemical (pH<2) which can permanently damage the eyes and produce serious chemical burns to the skin. Sulphuric acid is also poisonous, if swallowed.
What happens if you breathe in battery corrosion dust?Symptoms that can result from breathing in large amounts of the acidic battery fumes, or contents, dust, and smoke from burning batteries include: Bronchial irritation and cough. Decreased mental ability. Difficulty sleeping.
Should you wash your hands after touching batteries?Always practice good hygiene and wash your hands after handling a battery and before eating. If you handle the lead plates in a battery and don't wash your hands properly, you could be exposed to lead.
