There must be a portable fire extinguisher and a first aid kit in the room.
When the engine is running (especially at launch) carbon monoxide is released (carbon monoxide) - poisonous gas without color and smell. A life-threatening concentration of carbon monoxide can form even when the garage door is open, so before starting the engine, ensure the forced removal of exhaust gases outside the garage. In the absence of forced exhaust, you can start the engine for a short time by putting a piece of hose on the exhaust pipe, which is brought outside the garage. In this case, the exhaust system and its connection to the hose must be tight. When repairing electrical circuits and electrical equipment of the car, disconnect the wire terminal from «negative» battery outlet.
Before disconnecting the pipelines of the fuel system during maintenance and repair, it is necessary to relieve the fuel pressure in the system.
To protect hands from cuts and bruises during «power» operations wear gloves (better leather). Wear goggles to protect your eyes when using power tools (better special, with side shields).
Do not use a defective tool: open end wrenches with «revealed» gaps or crumpled jaws, screwdrivers with a rounded, twisted blade or incorrectly sharpened, pliers with loose plastic handles, hammers with a loose handle, etc.
When hanging the car with a jack, work should be carried out on a flat horizontal platform. Apply the parking brake, and put stops under the wheels. When installing a jack under the threshold, use only the places specified by the manufacturer. Use only a properly functioning jack.
Do not work under a vehicle that is only jacked up. For insurance, use a factory-made stand.
Before installing the stand, first make sure that the corresponding load-bearing elements of the body (floor reinforcements, thresholds) strong enough.
Do not jack up the vehicle on two or more jacks, use factory-made jack stands and jack stands.
It is forbidden to load or unload the vehicle while it is on a jack (get into it, remove or install the engine). When repairing a car with a dismantled engine (power unit) keep in mind that the weight distribution along the axes changes: when hanging on a jack, such a car may fall.
Used oils contain carcinogenic compounds. If oil gets on your hands, wipe them with a rag, and then wipe with a special «hand cleaner» (or sunflower oil) and wash with warm soapy water.
Do not wash your hands with hot water, as this allows harmful substances to easily penetrate the skin.
If you get gasoline on your hands, also wipe them off with a clean rag and then wash with soap and water.
The coolant of the engine cooling system (antifreeze) contains ethylene glycol, which is poisonous if ingested and, to a lesser extent, if it comes into contact with the skin.
The electrolyte in contact with the skin causes burning, redness. If electrolyte comes into contact with hands or eyes, wash it off first with plenty of cold water. Then the hands can be washed with a solution of baking soda or ammonia (from the car kit).
