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 too hot.
Burns
Any part of the engine is a risk of burns, especially the exhaust system. Brake parts may become hot immediately after braking.
The fall of a raised car
When working under or near a raised vehicle, always securely chock it under or use a trestle or pit.
Never work under a vehicle supported only by a jack!
Be careful when loosening or screwing fasteners that are tightened to a high torque if this work is carried out on a raised vehicle. In such cases, it is recommended that the initial release and final tightening be done with the vehicle lowered.
Fire
Fuel is highly flammable and its vapors are explosive.
Avoid spilling fuel onto hot engine surfaces.
Do not smoke or use open flames near the vehicle being repaired. Take precautions 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.
The sources of fire may be an overload or short circuit in the wiring. 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 high voltage wires can be dangerous, especially for people with heart problems.
Do not service the ignition system or adjacent units while the engine is running or the ignition is on.
Mains voltage is also dangerous. Make sure. that any mains powered equipment has a reliable earth connection. High voltage locations must be protected by residual current interrupters.
Vapor or gas poisoning
Exhaust fumes are poisonous. They contain carbon monoxide, which is fatal if inhaled. Do not allow the engine to run for a long time indoors.
Fumes from fuels and solvents used for cleaning and for thinning paints are also poisonous.
Poisonous and irritating substances
Avoid skin contact with electrolyte, fuel, especially diesel, brake fluid, grease and antifreeze. When pouring liquid from one container to another, do not suck liquid from the hose. If you accidentally swallow any liquid or get it in your eyes, contact your doctor immediately.
Prolonged contact with used engine oil can cause skin cancer. Work in 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.
Hydrofluoric acid
This highly toxic and corrosive substance is formed when certain types of synthetic rubbers are heated above 400°C, which are used to make some o-rings, cuffs, fuel hoses, etc. The rubber chars or turns into a solid substance containing fluoric acid. This acid is very stable and does not decompose for years. When it gets on the skin, sometimes it is necessary to remove the affected areas.
If you have to repair a vehicle that has been damaged by a fire, or handle parts removed from such a vehicle, wear protective gloves that 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 may cause injury if it deploys unexpectedly. Be careful when removing the steering wheel and bezel. 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.
Attention! Never put your hand or any other part of your body under the jet of fuel from the nozzle; Skin contact with fuel can be hazardous.
Need to know
Protect your eyes when using power tools and when working under a vehicle.
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 vehicle parts.
Remove rings, watches, etc. before working on the vehicle, especially wiring diagrams.
Before using lifting and supporting devices, make sure that they have sufficient safety margin.
It is forbidden
Do not try to lift what is beyond your capabilities - call an assistant.
Work slowly - take breaks.
Do not use a defective tool as it may break and cause injury.
Do not scatter the tool on the floor around you - someone may trip on it. Wipe up spilled oil immediately.
Do not allow children and pets to play in or near the vehicle being worked on.
