Batteries give off combustible gases which can
explode. A spark can cause the combustible
gases to ignite. This can result in severe personal
injury or death.
Ensure proper ventilation for batteries that are in
an enclosure. Follow the proper procedures in or-
der to help prevent electrical arcs and/or sparks
near batteries. Do not smoke when batteries are
serviced.
The battery cables or the batteries should not be
removed with the battery cover in place. The bat-
tery cover should be removed before any servic-
ing is attempted.
Removing the battery cables or the batteries with
the cover in place may cause a battery explosion
resulting in personal injury.
