Remember that breathing carbon monoxide (which is odourless) is a health
hazard.
When operating on engines or other parts of vehicles
- Use proper clothing and act safely in order to avoid accidents.
- Before starting, make sure that the vehicle gearbox is in neutral (or
parking position in the case of vehicles with automatic transmission).
Apply the handbrake or parking brake on the vehicle under test. Check
that the wheels are locked.
- Protect your face, hands and feet and avoid contact with hot parts such
as spark plugs, exhaust pipes, radiators, and cooling system connectors.
- Do not smoke and do not use flames while working on the vehicle.
- Check that all electric connections are isolated and firm.
- Do not look directly into the carburettor inlet while the engine is running.
- Keep hands and hair away from moving parts.
- Do not wear ties, slack clothing, wrist jewellery and watches while
working on a vehicle, especially when the engine is running.
- Keep away from the fan. The cooling fan is controlled by a temperature
switch which operates according to the temperature of the coolant:
disconnect the fan cable whenever operating on a warm engine, so that
the fan does not suddenly start up after the engine has been turned off.
- Do not pour fuel directly into the carburettor to start the engine quickly.
- Do not open the radiator cap before both the temperature of the engine
and the pressure of the cooling system have decreased.
- Do not touch high voltage cables while the engine is on.
- Handle portable lamps with care and use safety models only.
- Wear safety goggles to protect your eyes from fuel, dust and metal.
- Remember that the catalytic converter can become extremely hot and
cause severe injury or fires.
Take care to ensure that there is no spilt oil or any rags, paper or other easily
flammable material near the catalytic converter.
When operating on car batteries, remember that:
Car batteries contain sulphuric acid and produce explosive gases. Therefore,
keep the following in mind:
- Always wear safety eyewear.
- Do not leave instruments on batteries because they could cause short
circuits.
- Before testing or charging, cover the battery inlets with a wet rag to
choke any explosive gases.
- Avoid sparks when connecting cables to the battery.
