WORKING NEAR BATTERIES
Battery Hazard Prevention
• Battery electrolyte contains sulfuric acid, which
can quickly burn the skin and eat holes in
clothing. If you spill acid on yourself, immediately
flush the area with water.
• Battery acid can cause blindness if splashed into
your eyes. If acid gets into your eyes, flush them
immediately with large quantities of water and
see a doctor at once.
• If you accidentally drink acid, drink a large
quantity of water, milk, beaten eggs or vegetable
oil. Call a doctor or poison prevention center
immediately.
• Always wear safety glasses or goggles when
working with batteries.
• Batteries generate hydrogen gas. Hydrogen gas
is very explosive and can easily be ignited with a
small spark or flame.
• Before working with batteries, stop the engine
and turn the key switch to the OFF position.
• Avoid short-circuiting the battery terminals
through accidental contact with metallic objects,
such as tools, across the terminals.
• When removing or installing batteries, check
which is the positive (+) terminal and the negative
(-) terminal.
• Tighten battery caps securely.
• Tighten the battery terminals securely. Loose
terminals can generate sparks and lead to an
explosion.
Starting With Booster Cables
• Always wear safety glasses or goggles when
starting the truck with booster cables.
• When starting from another truck, do not allow
the two trucks to touch.
• Connect the positive (+) cable first when
installing booster cables. Disconnect the ground
or negative (-) cable first during removal.
• If any tool touches between the positive (+)
terminal and the chassis, it will cause sparks.
Always be cautious when using tools near the
battery.
• Connect the batteries in parallel: positive to
positive and negative to negative.
• When connecting the ground cable to the frame
of the truck to be started, connect it as far as
possible from the battery.
