Preliminary Work: Notes

→ Gasoline is toxic.

→ Inhaling vapours can cause irritation of the mucous membranes and eyes.

→ It can be carcinogenic. It represents a serious risk to health when inhaled, touched or swallowed over longer periods.

→ Only work on the fuel system in well-ventilated rooms.

→ Wear protective gloves that are fuel-resistant.

→ Wear a breathing mask with active charcoal filter; do not breathe in any fuel vapours.

→ Ensure that there is adequate ventilation and extract all fuel vapours.

→ Before opening the fuel lines or fuel hoses, relieve the fuel pressure.

→ Collect escaping fuel, absorb it if necessary with a suitable binding material and dispose of properly.

→ Pay attention to cleanliness when working on the fuel system.

→ Keep clear of ignition sources.

→ Do not smoke.

→ Disconnect battery.

→ Danger of fire due to naked flames and sparks, e.g. during welding or grinding work.

→ Danger of fire due to escaping fuel, e.g. on hot engine components or due to electrostatic charge. Allow engine to cool down.

→ Secure the vehicle, e.g. with a warning sign.

→ Change any clothing soaked with fuel immediately.

→ In case of fire, use CO2 or dry powder fire extinguishers.
