Storage batteries give off explosive hydrogen
gas. This gas can form an explosive mixture
around the battery for several hours after
charging. The slightest spark can ignite the gas
and cause an explosion. Such an explosion can
shatter the battery and cause blindness or
other injury. Any area that houses a storage
battery must be properly ventilated. Do not
allow smoking, open flame, sparks or any spark
producing tools or equipment near the battery.
Battery electrolyte fluid is an extremely caustic
sulfuric add solution that can cause severe
burns. Do not permit fluid to contact eyes, skin,
clothing, painted surfaces, etc. Wear protective
goggles, protective clothing and gloves when
handling a battery, if you spill the fluid, flush
the affected area immediately with clear water.
Do not use any jumper cables or booster bat­
tery to crank and start the generator engine, if
the battery has completely discharged, remove
it from the generator for recharging.
