3.2.4 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.
3.2.5 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 on skin, eyes and clothes, as it is a
•
corrosive and highly toxic compound.
