Battery rooms

Is battery room classified as hazardous location?
It depends on the following factors:
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.
