Prevent Battery Explosions

Battery gas can explode.
Keep sparks, lighted matches, and flame away from the
top of battery.
Never check battery charge by placing a metal object
across the posts. Use a voltmeter or hydrometer.
Do not charge a frozen battery; it may explode. Warm the
battery to 16 ˚C ( 60 ˚F ) first.
Do not continue to use or charge the battery when
electrolyte level is lower than specified. Explosion of the
battery may result.
Loose terminals may produce sparks. Securely tighten all
terminals.
Connect terminals to the correct electrical poles. Failure
to do so may cause damage to the electrical parts or fire.
Battery electrolyte is poisonous. If the battery should
explode, battery electrolyte may be splashed into eyes,
possibly resulting in blindness.
Be sure to wear eye protection when checking electrolyte
specific gravity.

Service Air Conditioning System Safely

If spilled onto skin, refrigerant may cause a cold contact
burn.
Refer to the instructions described on the container for
proper use when handling the refrigerant.
Use a recovery and recycling system to avoid leaking
refrigerant into the atmosphere.
Never touch the refrigerant.
