The ventilation system must prevent the accumulation of hydrogen pockets greater than 1% concentration. Flooded lead-acid batteries must be provided with a dedicated ventilation system that exhausts outdoors and prevents circulation of air in other parts of the building.
Unless exempted below, ventilation requirements for a room or area housing batteries are required to be as per manufacturer installation instruction, or calculated by a competent person (such as mechanical designer). Vented type batteries connected to a charging device with a power output of less than 200 Watt.
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.
Flooded lead-acid batteries must be provided with a dedicated ventilation system that exhausts outdoors and prevents circulation of air in other parts of the building. VRLA batteries require comparatively lower ventilation, usually enough to remove heat and gases that might be generated.
Vented lead acid batteries do not always require a separate, dedicated battery room when installed in medium voltage main substation buildings and unit substations, electrical equipment rooms, and control system rack rooms. However, the battery room and installation must comply with SES E14-S02, IEEE 484, NFPA 70, and OSHA 29 CFR.
Ventilation systems for stationary batteries must address human health and safety, fire safety, equipment reliability and safety, as well as human comfort. The ventilation system must prevent the accumulation of hydrogen pockets greater than 1% concentration.
