1. Avoid running the engine for a long time in an unventilated garage.

The exhaust gas from the engine contains carbon monoxide, which is a poisonous gas that is invisible and inaudible. Long-term exposure to low-concentration carbon monoxide gas can cause headaches, shortness of breath, nausea and vomiting, weakness and dizziness, mental confusion and even brain damage. If the engine is started in the garage, the door of the garage should be opened or the exhaust device should be opened so that the exhaust gas can be discharged from the garage at any time. Even if you are working in the open, do not stay for a long time near the exhaust pipe of the working engine.

 

2. Avoid using mouth suction pipe.

Gasoline is not only flammable and explosive, but also toxic. Especially leaded gasoline can damage the human nervous system, digestive tract and kidneys. In addition, gasoline also contains a high concentration of sulfide. Because hydrogen sulfide is also toxic, if gasoline is inhaled into the stomach, it will cause poisoning or death. In case of inhalation, force yourself to vomit and go to the hospital for treatment in time.

 

3. Avoid getting carburetor cleaning agent.

Most carburetor cleaners contain methyl chloride, aromatics and ethanol. These substances have certain toxicity. Therefore, these substances are very dangerous if they are inhaled into the nose or splashed on the skin and eyes. .

 

4.avoid mechanical damage.

The maintenance of a car is related to all aspects. When performing maintenance operations, clear work signs should be set to prevent other people from being injured by misoperation. When starting the car, pay attention to the gear position of the transmission to prevent the car from accidentally moving and hurting people. When working under the hood, other people should be allowed to leave the cab to prevent the sudden rotation of the engine or the action of other people's control mechanism, which may cause accidental injury. If you need to work under the car, you should set up obvious signs and cover the car with a car cover. When using a jack to support the truck, the jack should be placed steadily. Before driving, you should prepare driving tools (driving stool). It is forbidden to use fragile objects such as bricks. When installing the assembly, never try to test the screw holes, keyholes, etc. with your hands to avoid breaking your fingers. When testing the engine, do not work under the car.

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

 

6. Avoid burns.

The engine that has just been turned off, because the temperature of the engine's various parts (water tank, exhaust pipe, power steering fluid tank, spark plug, etc.) are relatively high, you must be careful to touch it to prevent burns. If the engine temperature is high, never remove the water tank cap or release the water switch to prevent burns.

When the engine is running, pay attention to the hands, clothing and tools must be kept away from the rotating fan and fan drive belt (it is best to remove the wearing ring, watch, tie and other items). During the test run, the conditions of all parts of the car should be able to ensure safe parking and effective steering. The car for road test must have a clear test sign. During the test drive, personnel must ride safely and proceed on a dedicated test track.

 

9. Avoid not paying attention to the cleaning of the workplace.

When closing the engine cover or other assembly covers, check whether the tools, rags, and removed parts are forgotten, and can only be closed after confirming that they are correct.
