Store fuels, lubricants and flammable substances in unbreakable containers on the floor or on shelves with flanges. If gasoline or solvent is spilled, do not turn on or off the light to avoid ignition from a spark between the switch contacts (switch off electric motors and heating devices immediately); ventilate the room. Cover any spilled oil with sand. Store oily rags separately, preferably in a metal box - fire hazard! Use weatherproof lighting to light the room, if possible (hermetically sealed) lamps, fluorescent lamps. It is also desirable to have a low-voltage network (up to 36 V) for work outdoors and on uninsulated floors, in pits, etc.
Use welding cylinders only with standard reducers. It is strictly forbidden to lubricate the oxygen cylinder valve or bring oily rags to it - this may cause an explosion.
When working with gas welding, glasses with dark lenses are required. For electric welding, a mask with a special light filter is needed. Glasses with transparent lenses or a mask are required when working with a cutting machine (grinder), an electric sharpener, and are desirable for drilling and metalwork.
When welding, stock up on a fire extinguisher (better with carbon dioxide). Before electric welding, disconnect all electronic control units from the vehicle's electrical system, and place the "ground" contact of the welding wire as close as possible to the welding site.
Make sure that current does not pass through the moving parts (bearings, ball joints) or threaded connections - they may be damaged.
When repairing electrical equipment circuits or when there is a risk of damage to them (welding, straightening near wire harnesses) disconnect the negative terminal of the battery.
Do not open the radiator cap on a hot engine - burns are possible. Do not disconnect on a running engine (and also with the ignition on) ignition system wires and devices - electric shock is possible. To avoid fire, do not disassemble the fuel system and its components and do not check the pressure in the fuel rail of the VAZ-21214 engine until the exhaust manifold has cooled down.
Keep your fingers away from rotating drives and engine cooling fan blades (all work with them should be carried out only when the electric motor power supply circuit is de-energized). When working near an aluminum radiator, be careful - its fins are very sharp. It is advisable to wear leather gloves or cover the radiator with a piece of cardboard or plywood.
When working in the engine compartment, thermal burns can be caused by the radiator, thermostat, cylinder head, exhaust manifold, downpipe, or spilled coolant (or jets of steam).
Do not use faulty tools: open-end wrenches with a "spread" mouth or crushed jaws, screwdrivers with a rounded or twisted slot, pliers with poorly secured plastic handles, hammers with an unfixed handle, etc. Wear gloves to protect your hands from cuts and bruises during "forceful" operations (leather is better). It is preferable to pull the key towards you rather than press it - this way there is less risk of injury.
When lifting a car, if possible, use diamond or hydraulic jacks instead of regular ones - they are more stable and reliable. When lifting or lowering a car (on a jack or lift), never be under it.
First make sure that the corresponding power elements of the body (floor reinforcements, thresholds) are strong enough. Use only the standard support points to lift the vehicle. It is prohibited to hang the vehicle on two or more jacks - use industrial stands. It is prohibited to load or unload the vehicle while it is on the jack (get into it, remove or install the engine, suspension springs, etc.), if there are people underneath it. When repairing a car with the engine removed (power unit) please note that the axle weight distribution has changed: when jacked up, such a vehicle may fall. Work only on a level, non-slip surface, and place stops under unjacked wheels.
When the engine is running, carbon monoxide is released - a poisonous gas without color or smell. You can get poisoned by it even in an open garage, so before starting the engine, ensure forced exhaust of exhaust gases outside the garage. If there is no such, the engine should be started for a short time, putting a section of hose on the exhaust pipe - while the exhaust system and its connection with the hose must be sealed!
Used motor and transmission oils contain carcinogenic compounds. Wipe oily hands with a rag, then wipe with a special "hand cleaner" (or sunflower oil) and wash with warm water and soap. Do not wash oily hands with hot water - harmful substances easily penetrate the skin! Wipe hands covered with gasoline with a clean rag and wash with soap.
Coolant and brake fluids can cause poisoning if ingested. If this happens, you should immediately induce vomiting, wash out the stomach, in case of severe poisoning take a saline laxative, and consult a doctor. If liquids get on your hands, wash them off with plenty of water.

Electrolyte on the skin causes burning and redness. Wash it off with plenty of cold water (you can't wash it off with soap!), then wash your hands with a solution of baking soda or ammonia. Remember that sulfuric acid, even in small concentrations, destroys organic fibers - take care of your clothes! When working with a battery (electrolyte is almost always present on its surface) wear goggles, protective clothing and rubber gloves.
Gasoline, oils, rubber products, plastics and brake fluid, lead batteries are processed in nature extremely slowly. Take care of the environment, take care of your health!
