Unusual Fire and Explosion Hazard
Hydrogen and oxygen gases are produced in the cells during normal battery operation
(hydrogen is flammable and oxygen supports combustion). These gases enter the air through
the vent caps. To avoid the chance of a fire or explosion, keep sparks and other sources of
ignition away from the battery.
