Regardless of your readiness to perform a particular job and our enthusiasm, first of all we should think about ensuring safety. Insufficient attention to this issue can lead to an accident. Failure to observe some of the most basic precautions can cause serious injury. Remember, the possibility of an accident is always present, and no list can cover all possible sources of danger. The list given below is intended rather so that you know and always remember the possible dangers and take the necessary precautions when performing any work on the car.
What to do and what not to do
- Do not use the jack as the only support when working under the vehicle. Be sure to place reliable supports under the vehicle, positioning them under the recommended locations for lifting the vehicle and installing the jack.
- Do not attempt to loosen tightly tightened fasteners (for example, wheel nuts), when the car is supported by a jack. This may cause the jack to fall.
- Do not start the engine without making sure the transmission is in neutral (or parking position, if applicable), and apply the parking brake.
- Do not remove the radiator cap when the cooling system is hot. Allow the system to cool or cover the cap with a thick cloth and gradually release the pressure.
- Do not attempt to drain the engine oil until you are sure it has cooled enough to avoid scalding you.
- Do not touch any part of the engine or exhaust system until they have cooled sufficiently to avoid burns.
- Do not suck out toxic liquids such as gasoline, antifreeze, and brake fluid by mouth or allow them to come into prolonged contact with your skin.
- Avoid breathing dust from brake linings. It is potentially hazardous (see "Asbestos" below).
- Don't let spilled oil or grease splatter on the floor. Wipe up any traces before someone slips.
- Do not use wrenches with a "broken" jaw or other tools that may slip and cause injury
- Do not apply pressure to wrenches when loosening or tightening nuts or bolts. Try to pull the wrench toward you. If the situation requires turning the wrench away from you, apply pressure with an open hand to avoid injuring your knuckles if the wrench slips.
- Do not attempt to lift a heavy item alone. Ask someone to help you.
- Don't look for or use shortcuts but dangerous ways to get the job done.
- DO NOT allow children or animals near or in the vehicle while you are working on it.
Use eye protection when working with power tools such as drills, grinders, etc. and when working under a car. Make sure that loose items of clothing and long hair are kept away from moving parts.
Ensure that the characteristics of the lifting equipment used are appropriate for the nature of the work being performed.

Have someone supervise you periodically when working on your vehicle alone.
Work in a logical sequence and make sure all components are correctly assembled and properly tightened. Keep chemicals and operating fluids in containers with tightly tightened lids, out of the reach of children and pets. Remember that the safety of the vehicle affects our personal safety and the safety of others. If in doubt, seek professional advice.
Asbestos
Certain friction, insulating, sealing and other components such as brake linings, band brakes, clutch linings, torque converters, gaskets, etc. may contain asbestos. Be very careful to avoid inhaling dust from these components as it is hazardous to health. If in doubt, it is recommended to assume that they contain asbestos.
Fire
Always remember that gasoline is highly flammable. Never smoke or allow an open fire in the vicinity when working with the vehicle. But the danger isn't just limited to that. Sparking caused by a short circuit in an electrical target, contact of metal surfaces with each other, or even static electricity accumulated on the human body under certain conditions can ignite gasoline vapors, which in a confined space become very explosive. Under no circumstances should gasoline be used to clean the elements. Use an approved, safe solvent.
Before working on any fuel system or electrical system component, always disconnect the negative (-) battery cable. Never spill fuel on a hot engine or exhaust system component. It is highly recommended that you keep a fire extinguisher suitable for use on fuel fires and electrical fires in your garage or service station. Never attempt to extinguish fuel or electrical fires with water.
Couples
Some vapors are highly toxic and can quickly cause unconsciousness or even death if inhaled in any quantity. Gasoline vapors fall into this category, as do some cleaning solvent vapors. Draining or pouring such volatile liquids should be done in a well-ventilated area.
When using cleaning fluids and solvents, carefully read the instructions on the container. Never use materials from containers that are not labeled.
Never work on the engine in a confined space, such as a garage. Exhaust gases contain carbon monoxide, which is highly toxic. If you need to start the engine, be sure to do so outdoors, or at least make sure the rear of the car is out of the work area.
If you use a pit for work, never drain or transfer gasoline and never start the engine when the car is parked over the pit. Vapors, which are heavier than air, accumulate in the pit and can be fatal.
Battery
Never allow sparks or use the lamp without a protective cover when working near a battery. The battery normally produces some hydrogen gas, which is highly explosive.
Before working on the fuel or electrical system, be sure to disconnect the battery ground cable.
If possible, loosen the filler caps or remove the overall cap when charging the battery from an external power source (this does not apply to sealed or maintenance-free batteries). Do not force charge the battery - this may cause the battery to explode.
Be careful when adding water to the battery and when carrying the battery. The electrolyte, even diluted, is highly corrosive. Therefore, do not allow it to come into contact with clothing or skin under any circumstances.
Be sure to use eye protection when cleaning the battery to prevent corrosive substances from getting into your eyes.
Household electrical networks
When using power tools, portable lamps, etc. that operate from a household electrical network, be sure to ensure that the power cord plugs of the tool are correctly inserted into the socket and that the tool is properly grounded (if necessary). Do not use such devices in wet conditions and take care that sparks or overheating do not occur in the area around fuel or fuel vapors.
Voltage in the secondary circuit of the ignition system
When touching certain parts of the ignition system (for example, spark plug wires) when the engine is running or cranking, especially if the components are wet or the insulation is faulty, a serious electric shock may occur. In the case of an electronic ignition system, the voltage in the secondary circuit is slightly higher and can be fatal.
