Thats a great question. Yes and no would be the answer. If the battery room does not have the right amount of ventilation then yes it would be. If the room had all the air changes required by the fire and building codes then no it would not. It all depends on how the fire department verifies the use and occupancy.

The fundamental answer is no.
A battery system otherwise installed per the NEC and manufacturer?s instructions does not warrant classifying the location. If it is not installed per the NEC and manufacturer?s instructions the installation will have an entirely different set of problems that classifying would not help. See Section 480.9.

a) What is the type and size of the battery? If it is a lead-acid type, it is necessary to know how much hidrogen is released during the charging process. This information needs to be given by manufacturer.
b) What is the total volume of the room? Only considering the amount of hidrogen released, is it able to reach the hidrogen LEL?
c) Is the room adequately ventilated? Has it an exhaust system that doesn't allow the LEL to be reached? Are interlocks provided, to stop charging if the exhaust system fails?
d) Has the room gas detectors? Is the installation following the NEC requirements regarding use of gas detectors as a type of protection for hazardous locations?
So, only after evaluating these points, we can say if the location is classified or not.

Read Article 490 in its entirety. Read the Scope (490.1) carefully. If a storage battery is installed ?per Code? there is no valid reason to classify it as hazardous (classified).hazloc2002 said:
