PREVENT ACID BURNS

Sulfuric acid in battery electrolyte is poisonous.   
It is strong enough to burn skin, eat holes in 
clothing, and cause blindness if splashed into 
eyes.

Avoid the hazard by:

1. Filling batteries in a well-ventilated area.
2. Wearing eye protection and rubber gloves.
3. Avoiding breathing fumes when electrolyte 

is added.

4. Avoiding spilling of dripping electrolyte.
5. Use proper jump start procedure.

If you spill acid on yourself:

1. Flush your skin with water.
2. Apply baking soda or lime to help neutralize 

the acid.

3. Flush your eyes with water for 10-15 

minutes.  Get  medical attention immediate-
ly.

If acid is swallowed:

1. Drink large amounts of water or milk.
2. Then drink milk of magnesia, beaten eggs, 

or vegetable  oil.

3. Get medical attention immediately.

USE TOOLS PROPERLY

Use tools appropriate to the work.   Makeshift 
tools, parts, and procedures can create safety 
hazards.

Use power tools only to loosen threaded tools 
and fasteners.

For loosening and tightening hardware, use the 
correct size tools.   DO NOT use U.S. 
measurement tools on metric fasteners.   Avoid 
bodily injury caused by slipping wrenches.

Use only recommended replacement parts.
(See Parts catalogue.)
