BATTERY PRECAUTIONS
The battery produces a flammable and explosive
hydrogen gas.

Do not cause a spark by contacting the battery
terminals with tools.

Do not smoke or light a match near the battery.
The electrolyte contains poisonous and corrosive sulfuric
acid.

Avoid contact with eyes, skin or clothes.

Never inhale or swallow electrolyte.

Wear protective safety glasses when working near the
battery.

EMERGENCY MEASURES

If electrolyte gets in your eyes, flush your eyes with
clean water for at least 15 minutes and get immediate
medical attention. If possible, continue to apply water
with a sponge or cloth while en route to the medical
office.
If electrolyte gets on your skin, thoroughly wash the
contacted area. If you feel a pain or burn, get medical
attention immediately.

If electrolyte gets on your clothes, there is a possibility
of its soaking through to your skin, so immediately take
off the exposed clothing and follow the procedure
above, if necessary.

If you happen to swallow electrolyte, drink a large
quantity of water or milk. Follow with milk of magnesia,
beaten raw egg or vegetable oil. Then go immediately
