Battery Storage
Battery Storage
(OP)
One the facilities of my organization rents recreational gear, such as Bass and Jon boats, to the public; with the boats we also issue batteries. The batteries, (6) total, set on the floor of our warehouse when they are not in use (not a locked room but the area is accessible only to employees). Recently, a Fire Inspector told us that the batteries had to be stored in a flammable locker. He sited NFPA 70E, 320.4(A) and (C). After reading Article 320.4 I feel like it is being mis-applied to the situation (I pictured battery banks and UPS boxes).
In another one of my facilities we have batteries for resale, like you would see at Auto Zone or Walmart. If we are truley required to place our (6) rec batteries in a locker or deticated battery room, then I would think the same would apply to our resale batteries.
Any guidance or clarification in reference to NFPA 70E, 320.4 would greatly be appreciated.

RE: Battery Storage
The hazard with rechargeable cells is generally hydrogen gas which is produced during during charging. Hydrogen forms an explosive mixture with air, so it's not something you want building up. If these are valve-regulated batteries then the chances of hydrogen being evolved are pretty slim because this type of battery is specifically designed not to vent hydrogen if it is used within the manufacturer's guidelines for charging rate.
If the batteries are just sitting there and aren't being charged then I don't know why they would need to be in a falm store.

But since your rental carry-away batteries are not "permanently installed"...

Obey the Inspector. Resistance is futile!
RE: Battery Storage
Nevertheless, sometimes it is not worth fighting city hall. A number of years ago an inspector insisted one of my clients install ventilation for the starting batteries on a diesel generator. It was a large generator room with plenty of natural "leakage". The fans were completely silly, but it was clear this young inspector was not going budge, in spite of a letter from the PE of record (yours truly).

RE: Battery Storage
Your application is identical to batteries placed in racks at the "battery store".. They do not require locked flame cabinets either. The inspector is clearly incorrect.
