BATTERY SAFETY
DANGER
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. AN EXPLOSION CAN SHATTER THE BATTERY AND CAUSE BLIND-
NESS 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.
WARNING
Risk of burns. Batteries contain sulfuric acid and can cause severe chemical burns.
Wear protective gear when working with batteries. Failure to do so could result in
death or serious injury. (000138a)
Observe the following precautions when working on batteries.
• Servicing of the battery is to be performed or supervised by personnel knowledgeable of batteries and the
required precautions. Keep unauthorized personnel away from batteries.
• Remove the 10A F2 fuse from the generator control panel.
• Remove watches, rings, or other metal objects.
• Use tools with insulated handles.
• Wear rubber gloves and boots.
• Do not lay tools or metal parts on top of the battery.
• If applicable, disconnect the charging source before connecting or disconnecting battery terminals. Remove
the battery charger fuse (ATC style fuse, 5 amp on the 2.5A charger and 15 amp on the 10A charger).
• Wear full eye protection and protective clothing.
• Where electrolyte contacts the skin, wash it off immediately with water.
• Where electrolyte contacts the eyes, flush thoroughly and immediately with water, and seek medical attention.
• Spilled electrolyte is to be washed down with an acid neutralizing agent. A common practice is to use a
solution of 1 lb. (454g) bicarbonate of soda to 1 gal (3.8L) of water. The bicarbonate of soda solution is to
be added until the evidence of reaction (foaming) has ceased. The resulting liquid is to be flushed with water.
• Lead-acid batteries present a risk of fire because they generate hydrogen gas.
• DO NOT SMOKE when near the battery.
• DO NOT cause flame or spark in battery area.
• Discharge static electricity from the body before touching the battery by first touching a grounded metal
surface.
• DO NOT dispose of the battery in a fire. The battery is capable of exploding.
• DO NOT open or mutilate the battery. Released electrolyte can be toxic and harmful to the skin and eyes.
• The battery represents a risk of high short circuit current. When working on the battery, always remove
watches, rings, or other metal objects, and only use tools that have insulated handles.
• Be sure control power switch is OFF before connecting the battery cables. If the switch is set to AUTO or
MANUAL, the generator can crank and start as soon as the battery cables are connected.
• Be sure the utility power supply to the battery charger is turned OFF and the 10A and 15A fuses are removed
from the generator control panel and the ATC style fuse removed from the battery charger, or sparking may
occur at the battery posts as the cables are attached and cause an explosion.
