PERSONAL PRECAUTIONS
Ensure there is another person within hearing range of your voice and close enough to come to your aid, should a problem arise when
9
working near a lead-acid battery.
Wear safety eye protection and protective clothing. Avoid touching eyes while working near battery.
9
Have fresh water and soap nearby in case battery acid contacts skin, clothing or eyes.
9
Wash immediately with soap and water if battery acid contacts skin or clothing. If acid enters eye, flush eye immediately with cool, clean
9
running water for at least 15 minutes and seek immediate medical attention.
Remove personal metallic items such as rings, bracelets, necklaces and watches. A lead-acid battery can produce a short-circuit current
9
which is high enough to weld a ring or the like to metal, which would cause severe burns.
Ensure hands, clothing (especially belts) are clear of fan blades and other moving or hot parts of engine, remove ties and contain long hair.
9
DO NOT smoke or allow a spark or flame in the vicinity of battery or engine.
