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.
Battery room 144,000 cu. ft. from example in Step 2 V = R x P ÷ H x 60 minutes (V) = Ventilation required (R) = Room cu. ft. (P) = Maximum percentage of hydrogen gas allowed (H) = Total hydrogen produced per hour V = 144,000 x .01% ÷ 596.97 x 60 V = 144.73 or the air should be exchanged every 144.73 minutes (2 hours 24 minutes) 4.
Assume 1000 cu-ft of room volume is covered by battery equipment. In order to be certain that the ventilation of the battery room is adequate to keep the average concentration of hydrogen gas in the room within safe limits, it is necessary to be able to calculate the rate of evolution of hydrogen.
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.
