Car maintenance taboo:

1, avoid running the engine for a long time in an unventilated garage. The exhaust gas from the engine contains carbon monoxide, which is an invisible and odorless poisonous gas. Don't stay near the exhaust pipe of the working engine for a long time, even if you work in the open air.

2. Avoid sucking the tubing with your mouth. Gasoline is not only flammable and explosive, but also toxic. Especially leaded gasoline, will damage people's nervous system, digestive tract and kidneys. In addition, gasoline also contains high concentration of sulfide, because hydrogen sulfide is also toxic, if inhaled gasoline, it will lead to poisoning or death. In case of inhalation, force yourself to vomit and go to the hospital for treatment in time.

3. Avoid using carburetor cleaner. Carburetor cleaning agents mostly contain methyl chloride, aromatic hydrocarbons and ethanol, which are toxic to some extent, so it is very dangerous for these substances to be inhaled into the nose or splashed on the skin and eyes.

4. Avoid mechanical injury. The maintenance of a car is related to all aspects. During maintenance operations, obvious operation signs should be set to prevent others from being injured due to misoperation.

5, avoid fire. When maintaining cars, it is often necessary to use flammable and explosive materials such as oil and cleaning agents. Don't forget the fire-fighting measures at this time, and prepare a fire extinguisher just in case. Don't smoke near the fuel tank and battery, because combustible gas escaping from the fuel tank and hydrogen escaping from the battery can be easily ignited.

6. Avoid burns. The engine that has just turned off must be handled carefully to prevent burns caused by relatively high temperatures in various parts of the engine (water tank, exhaust pipe, power steering fluid tank, spark plug, etc.). ). If the engine temperature is high, do not remove the water tank cover or loosen the drain switch to avoid burns.

7. Avoid damaging the car. Brake fluid is harmful to automobile paint film (including leather shoes paint film) and can quickly dissolve paint film. Brake fluid is harmful to eyes. If it spills into eyes, it must be washed with clear water immediately.

8. Do not pay attention to the protection of rotating parts and automobile road test.

9. Do not pay attention to the cleanliness of the workplace. When closing the engine cover or other assembly covers, check whether tools, rags, removed parts and other items are forgotten, and then close them after confirmation.
