Battery rooms shall be designed with an adequate exhaust system which provides for continuous ventilation of the battery room to prohibit the build-up of potentially explosive hydrogen gas. During normal operations, off gassing of the batteries is relatively small.
The battery room shall be ventilated by means of two exhaust fans (one working + one standby). The standby fan should start automatically in case the other fails, Each fan shall have an independent failure alarm. The fan shall be mounted as high as possible in the wall, but not below the level of the light fittings.
Batteries of the non-seal type shall be located in enclosures with outside vents or in well ventilated rooms, so arranged as to prevent 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.
Article 480-9 of the National Electric Code requires each vented battery cell to be equipped with a flame arrester designed to prevent destruction of the cell attributable to an ignition of gases outside the cell. The cable opening shall be adjacent to the wall and stands where applicable.
The battery rooms must be adequately ventilated to keep the concentration of hydrogen gas within safe limits. Some codes suggest that the battery rooms shall be ventilated at a minimum rate of 1.5 cubic feet per minute per square foot, with care to ensure proper air distribution to and within the battery storage area.
The ventilation system for the battery room shall be separate from ventilation systems for other spaces. Air recirculation in the battery room is prohibited. Exhaust air through a dedicated exhaust duct system if the battery room is not located on an outside wall.
