Lead-acid batteries

SECTION 2: Hazards identification

No hazards occur during the normal operation of a Lead Acid Battery as it is described in the instructions for use that are provided with the Battery. If a separate acid pack is provided with the lead-acid battery, a separate Safety Data Sheet in line with REACH Art. 31 is provided. Please take notice of the hazards and safe use information provided for the acid pack. 2.2 Characteristics Lead-acid Batteries have significant characteristics: • They contain an electrolyte which contains diluted sulphuric acid. Sulphuric acid may cause severe chemical burns. • During the charging process or during operation they might develop hydrogen gas and oxygen, which under certain circumstances may result in an explosive mixture. • They can contain a considerable amount of energy, which may be a source of high electrical current and a severe electrical shock in the event of a short circuit. • Standard EN 50272-2 included safety requirements for batteries and battery installations and describes the basic precautions to protect against dangers deriving from electric currents, leaking gases or electrolytes.

2.2 Label elements

The batteries have to be labelled with the symbols listed under section 15. SECTION 3.
