Always keep the passage to the exit free.
When the engine is running (especially on warm-ups) carbon monoxide is released (SO) - poisonous gas without color and smell. Get poisoned with carbon monoxide (carbon monoxide) it is possible even in an open garage, therefore, before starting the engine, ensure that exhaust gases are removed outside the garage. For example, with a hose, putting it on the exhaust pipe. In the absence of forced ventilation, the engine can only be started for a short time. In this case, the exhaust system and its connection to the hose must be tight!
When repairing the engine power system, be careful: gasoline can get on the hot exhaust manifold and cause a fire. Don't turn on (and don't turn off) electrical appliances of the car, if gasoline is spilled nearby - a slipped spark (even when removed «negative» battery terminals) may cause an explosion.
Keep a bucket of water and a fire extinguisher handy while welding (better carbon dioxide). Before doing this, disconnect all electronic control units and the battery from the vehicle's on-board network, and «mass» Place the welding wire contact as close as possible to the welding point. Ensure that current does not pass through moving parts (bearings, ball bearings) or threaded connections - they can be damaged.
When repairing circuits of electrical equipment or at the risk of damage to them (welding, straightening near wiring harnesses) disconnect the terminal «minus» battery.
When servicing the non-contact ignition system, do not touch the high voltage wires while the engine is running or starting.
When checking the ignition system «for a spark» fix the high voltage wire near «masses» tape, clothespin, but do not hold it with your hands. If you want to turn off one of the cylinders while the engine is running, close the high-voltage output to the «mass». In this case, the shunt wire must first be securely fastened to «mass», and then bring it to the tip of the high-voltage wire (better not to touch it with your hands).
If you prefer to disconnect the high voltage wires to disable the cylinders (and this can lead to burnout of the insulation of the ignition coil, runner and distributor cap), then it is better to disconnect them not from the candles, but from the ignition distributor - this way there is much less chance of getting an electric shock.
Wear gloves to protect your hands while working (better leather). Wear safety goggles with side shields to protect your eyes.
Carry out electrical work in tight clothing (better than canvas), by buttoning up the sleeves and collar.
If possible, use rhombic or hydraulic jacks instead of standard ones - they are more stable and reliable. Do not use a defective tool: open end wrenches with «revealed» gaps or crumpled jaws, screwdrivers with a rounded, twisted slot or incorrectly sharpened, pliers with loose plastic handles, hammers with a loose handle, etc.
Before raising the vehicle on a jack or lift, make sure that the appropriate load-bearing elements of the body (floor reinforcements, thresholds) strong enough. Use only standard support points to lift the vehicle. It is forbidden to hang the car on two or more jacks - use serviceable stands of industrial production («tripod») and secure wheel chocks.
It is forbidden to load or unload the car on the jack, get into it, remove or install the engine if there are people under the car. When repairing a car with the engine or axle removed, keep in mind that the axle weight distribution has changed. When hanging on a jack, such a car may fall. Work only on a flat, non-slippery area, place reliable stops under the wheels that are not jacked up.
Oils, especially used ones, with regular contact with them, contribute to the occurrence of skin diseases, incl. oncological. If oil gets on your hands, wipe them with a rag, and then wipe with a special preparation for cleaning hands (or sunflower oil) and wash with warm water and soap or dishwashing detergent. Do not wash your hands with hot water, because. while harmful substances easily penetrate the skin. If you get gasoline, kerosene or diesel fuel on your hands, wipe them off with a clean cloth and then wash with soap and water.
When working with a battery (electrolyte is almost always present on its surface) be sure to wear goggles and protective clothing, incl. latex gloves.
The electrolyte in contact with the skin causes redness, burning. If electrolyte comes into contact with hands or eyes, wash it off with plenty of cold water (do not wash with soap!), then hands should be washed with a solution of baking soda or ammonia.
Remember that sulfuric acid, even in small concentrations, destroys organic fibers - take care of your clothes.
in coolant (antifreeze) contains ethylene glycol, which is poisonous if ingested and (less) upon contact with the skin. In case of poisoning with antifreeze, you should immediately induce vomiting, rinse the stomach, and in case of severe poisoning, take a saline laxative, consult a doctor. In case of contact with hands, wash with plenty of soap and water. The same applies to brake fluid.
Do not open the cooling system caps on a hot engine.
Gasoline, diesel fuel, oils, brake fluid are almost not recycled naturally. Brake fluid contains toxic glycol ethers; oils - spent mineral and organic additives, soot, resins, wear products. Lead batteries, in addition to lead, contain antimony and other elements that form highly toxic compounds for living organisms that remain in the soil for a long time. Leave used materials at recycling points.
