lead particles to come into contact with
eyes, skin or clothing.
- Battery acid is extremely corrosive. Wear
protective gloves and safety glasses. Do
not tilt the battery - acid can leak out of

consult a doctor immediately.
- Keep open flames, sparks, uncovered
lights and lit cigarettes away from bat-
tery. Avoid sparks (including those from
static charges) when handling cables and
electrical equipment. Never cross the
battery poles. The resulting high-energy
sparks can cause injury.
- A highly explosive mixture of gases is
given off when the battery is under
charge. Only charge battery in a well ven-
tilated area.
- Keep ch ildren away from the battery and
battery acid.
- Switch off all electrical equipment be-
fore starting any work on the vehicle
electrical system. Remove the ignition
