Main types of danger
Scalding
Do not remove the radiator cap or expansion tank until the engine is cold.
Immediately after the engine has stopped, the engine oil, transmission and steering fluids may also be very hot.
Burns
Any part of the engine is a risk of burns, especially the exhaust system. Brake discs and drums may become hot immediately after braking.
The fall of a raised car
When working under or next to a raised vehicle, always place strong blocks under the vehicle. or use a flyover or viewing hole.
Never work under a machine supported only by a jack!
Use caution when loosening or driving fasteners that are overtightened when this work is being done with the machine raised. It is recommended that the initial loosening and final tightening in such cases be carried out with the vehicle lowered.
Fire
Fuel is highly flammable; fuel vapors are explosive.
Do not allow fuel to come into contact with hot engine surfaces.
Do not smoke or use open flames near the vehicle while it is undergoing any repairs. Protect against sparks from electrical appliances or hand tools.
Fuel vapors are heavier than air, so do not work on the fuel system in a pit.
Another source of fire is an overload or short circuit in electrical wiring circuits. Be careful when repairing or replacing electrical equipment.
Have a fire extinguisher on hand suitable for extinguishing burning fuel and electrical wiring.
Electric shock
Ignition system high voltage wires can be dangerous, especially for people suffering from heart disease. Do not service the ignition system or adjacent units while the engine is running or the ignition is on.
Vapor or gas poisoning
Exhaust fumes are poisonous.; they usually contain carbon monoxide, which is rapidly fatal if inhaled. Never run the engine for extended periods in an enclosed area such as a closed garage.
Poisonous are also fuel vapors and various solvents used for cleaning, as well as for diluting paints.
Poisonous and irritating substances
Avoid skin contact with electrolyte, fuel. especially diesel. brake fluid, lubricants and antifreeze. If you need to pour liquid from one container to another, do not suck liquid from the hose with your mouth. If you accidentally swallow any liquid or get it in your eyes, seek medical attention immediately.
Prolonged contact with used engine oil can cause skin cancer. If necessary, wear rubber gloves or lubricate your hands with a protective cream. Change clothes that have been exposed to oil and do not carry oily rags in your pocket.
Air conditioner refrigerant can form poisonous gas when in contact with fire, including cigarettes. It can also cause skin burns.
Asbestos
Asbestos dust is a carcinogen: it can cause cancer if inhaled or swallowed. Asbestos is an integral part of some gaskets, as well as brake and friction linings. When working with such nodes, the presence of asbestos in them should be assumed.
Specific Hazards
Hydrofluoric acid
This highly toxic and corrosive substance is formed when certain types of synthetic rubber are heated above 400°C, from which some O-rings are made. cuffs, fuel hoses, etc. Rubber chars or turns into a solid containing hydrofluoric acid. This acid is very stable and does not decompose for years. When this acid gets on the skin, it is sometimes necessary to amputate the affected organ.
If you have to repair a car that has been damaged by fire or deal with parts removed from such a car. work in protective gloves, which must be destroyed after work.
Battery
The battery contains sulfuric acid, which is extremely harmful to skin, eyes and clothing. Be careful when filling and carrying the battery.
Hydrogen that can be released from the battery is explosive. Do not use open flame and avoid creating sparks near the battery. Be careful when connecting and disconnecting the charger and other portable cords.
Airbags
The airbag can cause injury if it deploys unexpectedly. Be careful when removing the steering wheel and dashboard. Follow the instructions for handling the pillow.
Diesel fuel equipment
The diesel fuel pump creates very high pressure. Be careful when working with the pump and nozzles.
Warning: Never expose your hand, face, or any other part of your body to the jet of fuel from the nozzle: fuel can penetrate the skin and cause dangerous consequences.
Remember, that...
Necessary:
- Protect your eyes when using power tools and when working under the machine.
- Use gloves or protective cream if necessary.
- If you're working alone, have someone check in from time to time to make sure you're all right.
- Keep loose clothing and long hair away from moving machine parts.
- Remove rings, watches, etc., before working on the vehicle, especially on wiring diagrams.
- Before using lifting and supporting devices, make sure that they have sufficient strength for the intended work.
It is forbidden:
- Don't try to lift it then. what is beyond your capabilities - call an assistant.
- Work slowly - take breaks.
- Do not use a defective tool - it may break and cause injury.
- Do not scatter tools on the floor around you - someone may trip over them. Wipe up spilled oil.
- Do not allow children and pets to play in or near the vehicle being worked on.
