Lead-acid battery storage room

Do vented lead acid batteries need a separate battery room?

Vented lead acid batteries installed in medium voltage main substation buildings and unit substations, electrical equipment rooms and control system rack rooms shall not require a separate, dedicated battery room and shall be in accordance with SES E14-S02. The battery room and installation shall comply with IEEE 484, NFPA 70 and OSHA 29 CFR.

Do lead-acid batteries release hydrogen gas?

It is common knowledge that lead-acid batteries release hydrogen gas that can be potentially explosive. The battery rooms must be adequately ventilated to prohibit the build-up of hydrogen gas. During normal operations, off gassing of the batteries is relatively small.

Where should lead acid batteries be located?

Vented lead acid batteries shall be located in rooms with outside air exchange, or in well-ventilated rooms, arranged in a way that prevents the escape of fumes, gases, or electrolyte spray into other areas. Ventilation shall be provided to ensure diffusion of the gases from the battery, to prevent the accumulation of an explosive mixture.

Why are lead-acid batteries dangerous?

Lead-acid batteries release hydrogen gas that is potentially explosive.The battery rooms must be adequately ventilated to prohibit the build-up of hydrogen gas.The hydrogen generation is relatively small during normal operation.However, significant hydrogen can be produced during rapid and deep discharge of the battery.

Why is battery room cleanliness important?

Battery room cleanliness and ventilation are important because the battery chemistry for lead-acid storage batteries is sensitive to contaminants and temperatures above and below the manufacturer’s rating. In addition, the batteries also release hydrogen (a potential fire hazard) to the battery room during charging.

What are the legal requirements for lead-acid batteries?

The legal requirements for lead-acid batteries in relation to “end of useful life” are such that they should be disposed in a manner that is appropriate to the current laws and regulations within the state. The storage of the batteries has to be such that it conforms to the safety rules and regulations.
