Safety With Batteries
Keep these 10 safety precautions in mind when working with batteries.
1. The battery acid used in batteries is very toxic and
corrosive. Never let the battery acid get on your
clothes or skin.
2. Battery acid can be neutralized by mixing baking
soda with the acid. Always have a box of baking
soda nearby when working on batteries. If battery
acid gets into your eyes, flush immediately with tap
water for at least 15-20 minutes. Seek medical
3. Never place tools on the top of the battery,
especially on older batteries that have the terminals
on top. If the terminals are shorted by a tool,
sparks will be produced and excessive current will
heat the tool to its melting point, possible causing
injury to a person.
4. When batteries are discharged and charged,
hydrogen gas, which can be highly explosive, is
produced. Keep sparks from the electrical system
away from the battery.
5. Do not use an excessive charge rate or charge
batteries with cells that are low on electrolyte.

6. When working around batteries, always wear
protective clothing as well as safety glasses.
7. Batteries are very heavy. Always lift the battery
using the correct lifting tool, as back injury may
occur during lifting.
8. When cleaning battery posts, be careful that the
corrosion built-up on the posts does not get onto
your skin or cloths. It is very acidic and may cause
acid burns as well as ruin your cloths.
9. Never smoke in or around an automobile when
working on its battery.
10. Battery acid is considered a hazardous waste
product. Batteries should not be thrown away, as
damage to the environment may result. Stores
that sell batteries normally take old batteries and
properly dispose of them. When buying a new
battery, bring your old battery to the seller for
