NFPA 70E Battery and Battery Room Requirements | NFPA
Safety requirements for batteries and battery rooms can be found within Article 320 of NFPA 70E.
Battery Room Considerations
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 be avoided.
Battery Room
20.12 Battery Rooms. Battery rooms are provided for backup and uninterruptible power supplies (UPS) for process control functions. They are usually provided at or near the facility control room or electrical switchgear facilities. Battery rooms should be provided with ventilation to limit the concentration of hydrogen to 1% by volume.
