ENGLISH 5 / 35 CHAP. 3 - SAFETY CONDITIONS
OPA-100
RISK OF
INJURIES
There are mobile parts in stationary or running engines (belts and so forth) that can
cause serious injury hands and arms. Amongst the various engine components, pay
the greatest attention to electric fans since they can start operating unexpectedly even
when the engine is off.
SAFETY MEASURES
- Never place your hands near moving parts whilst the engine is running
- If you must work near electric fans, first allow the engine to cool and remove the
fan plug from the motor.
- Keep the connection cables of test instruments well away from the moving parts
of the engine.
RISK OF BURNS
Some of the engine components (eg. exhaust gas manifolds) can become very hot, as
can some of the sensors. Take great care to avoid touching these components.
SAFETY MEASURES
- Wear protective gloves.
- Allow the engine and any self-contained accessory heaters to cool down.
- Do not route the connection cables of test instruments over or near hot parts.
- Do not keep the engine running after the tests.
DANGER OF FIRE OR EXPLOSION
There could be a risk of fire outbreak or explosion when work is carried out on the fuel
system (fuel pump, injectors and carburettor, etc.) due to the fuels used and/or the
vapours they create.
SAFETY MEASURES
- Disconnect the ignition system.
- Allow the engine to cool.
- Do not use naked flames or components that produce sparks.
- Do not smoke.
- Clean up any spilt fuel.
- Operate exhaust extraction fans in closed rooms.
