The regulations for battery room ventilation vary greatly between countries. They also fall under numerous different governing authorities from Federal to state, provincial and even local authorities. It is extremely important to ensure that you comply with all governing bodies when installing ventilation in your battery charging area.
BATTERY ROOM VENTILATION AND SAFETY. 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.
Ventilation. The battery room should be sufficiently well ventilated to prevent the accumulation of hydrogen and oxygen given off during recharging. As hydrogen is lighter than air and is likely to concentrate near ceiling level, air bricks and vents should be sited high up on outside walls and unvented structural pockets in the ceiling should ...

Battery Room Ventilation . The purpose of battery room ventilation is to protect workers from exposure to lead fumes and other harmful gases that are produced when batteries are being charged. Lead acid batteries produce hydrogen gas when they are being charged, and this gas can be explosive if it builds up in a confined space. ...
Adequate ventilation is provided in all battery rooms to keep the concentration of hydrogen gas in the room within safe limits. It must be remembered that hydrogen is lighter than air and diffuses upwards very rapidly.
