I once had a set of 3000 anp phone co. cells I used for 24 volts. Each cell
had a felt breather on top to isolate the hyrdogen inside the cell from the
air outside in case of a fire. this was to prevent an explosion inside the
cell. My equipment was separated from my cells and the cells were ventalated
with a open window. I never had any problems. simple separation and
ventalation is sufficent in most cases.
