- Working in the vicinity of a lead acid battery is dangerous. Batteries can generate explosive gases during
operation. Never smoke or allow a spark or flame in the vicinity of a battery. Provide sufficient ventilation around
the battery.
- Wear eye and clothing protection. Avoid touching eyes while working near batteries. Wash your hands when
done.
- If battery acid contacts skin or clothing, wash them immediately with soap and water. If acid enters an eye,
immediately flood the eye with running cold water for at least 15 minutes and get medical attention immediately.
- Be careful when using metal tools in the vicinity of batteries. Dropping a metal tool onto a battery might cause a
short circuit and possibly an explosion.
- Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a battery. A
battery can produce a short circuit current high enough to melt objects such as rings, causing severe burns.
- Disconnect the negative pole of the battery before installation.
