Aircraft Battery |
Explosion of hydrogen gas ejected the aluminum
cover through the aircraft engine cowling. Usually caused by spark.
Batteries expel explosive gasses. Keep sparks, flames, burning
cigarettes or other ignition sources away at all times. Always wear safety
goggles and a face shield when working near batteries. Production of
explosive battery gasses alone does not cause a battery to explode. It's
the combination of explosive gasses and some type of spark or flame that,
on a rare occasion, results in an explosion. If a battery explodes during
starting, for example, this is often caused by a low level of battery
fluid and/or an inadequate cable connection.
A battery explosion is a rare occurrence. However, since it is a
possibility, it's important to follow battery safety tips (see below) when
working on or near batteries.
Several factors increase the possibility of a battery
explosion:
(1) low water level in the battery,
(2) overcharging,
(3) high electrolyte temperature,
(4) a poor external connection and
(5) poor jump starting procedures.
