My understanding is battery rooms containing vented lead acid storage batteries should be classified as Class I, Division 1 (Group B).
Per Article 480.10, if sufficient ventilation is provided within the room it need not be classified under Article 500. We have several of these rooms on site. They are quite small and probably do not meet the required CFM for declassification. However each room contains a vent fan, gas detector, air-flow switch and trouble alarm to DCS. The Area Class drawing shows them as Class I Division 2 - not Unclassified. Isn't this a bit overkill?
