Safety Precautions:
•
Always make sure that the vehicle is in neutral gear (or that it is set in parking
position in case of a vehicle equipped with automatic transmission).
•
Always activate the hand brake or parking brake on the vehicle.
•
Always block the wheels on the vehicle with the specific mechanical blocks.
•
Make sure the device is stable, on a flat surface and the wheels are locked with
the specific brakes.
2.2.4 Hazards Caused by Moving Parts
Vehicle engines include parts that move, both while running and not
running (eg: the cooling fan is controlled by a thermal switch in
connection with the coolant temperature and become activated even
when the vehicle is off), that can injure the operator.
Safety Precautions:
•
Keep hands away from moving parts.
•
Disconnect the engine cooling fan each time the engine you are working on is
still hot. This will avoid the fan from becoming activated unexpectedly even when
the engine is off.
•
Do not wear ties, loose clothes, wrist jewellery or watches when working on a
vehicle.
•
Keep connection cables, probes and similar devices away from the moving parts
of the engine.
2.2.5 Risk of Burning or Scalding
The parts that are exposed to high temperatures in engines that are
moving or have just stopped could burn the operator.
Remember that catalytic mufflers reach very high temperatures, able
to cause serious burns or even start fires.
Acid in the vehicle batteries is another potential hazard.
Safety Precautions:
•
Protect your face, hands, and feet by using suitable protection.
•
Avoid contact with hot surfaces, such as spark plugs, exhaust pipes, radiators
and connections within the cooling system.
•
Make sure there are no oil stains, rags, paper or other inflammable material near
the muffler.
•
Avoid splashing electrolyte onto your skin, eyes and clothes, as it is a corrosive
and highly toxic compound.
