Safety rules for mechanics cover all aspects from «no smoking near petrol» before «use the right tool for the job». In order not to endanger your health, you should develop the skills to perform work safely and observe all possible precautions.
Necessary
Have a fire extinguisher and a first aid kit near the workplace.
Wear safety goggles when cutting, drilling, grinding or when using the lifting arms. If you wear glasses to improve your vision, then they must be made of tempered glass so that they can also be used as safety glasses or you need to wear safety glasses over your regular glasses.
Protect your eyes when working with the battery. Batteries contain sulfuric acid. If sulfuric acid comes into contact with your skin, wash the area with water or a mixture of water and baking soda and seek medical attention immediately.
Use safety stands during any work under the machine. Jacks are used to lift cars; safety stands are used to keep the car in a raised state until you want to lower it.
In all cases, when the car is not raised on stands, it is necessary to place blocks under the wheels and apply the parking brake.
Ensure adequate ventilation when using any chemicals. Asbestos dust resulting from worn brake linings is carcinogenic.
Disconnect the ground wire from the battery when working on the electrical system.
Follow instructions when handling materials that are potentially hazardous to health. Both brake fluid and antifreeze are poisonous, they can cause poisoning of the body.
Keep the instrument in good order. Loose hammer heads, mushroom-shaped punches and chisels, frayed or poorly grounded electrical wires, excessively worn screwdrivers, set open-ended wrenches, cracked heads, slipping ratchet mechanisms, or faulty light bulb sockets can cause accidents.
Use a tool of the size and name that is necessary for this work.
Whenever possible, pull the wrench handle towards you instead of pushing it away from you.
Make sure that the adjustable wrenches fit snugly on the nut or bolt and the force is applied to them so that the edge is in contact with the fixed jaw of the wrench.
The wrenches or heads must fit the nut or bolt and sit on them without distortion.
Apply the parking brake and block the wheels if the work requires the engine to be turned on.
Not recommended
Turn on the engine in the garage or where there is no ventilation. Carbon monoxide is poisonous! Early symptoms of carbon monoxide poisoning include headache, irritability, blurred vision (blurry outlines or inability to concentrate) and/or drowsiness. If any of these symptoms occur to you or your helpers, stop work immediately and go outside for fresh air. Ventilate the area thoroughly before returning to the vehicle.
Wear a tie or other loose clothing when working near rotating parts. Short sleeves are much safer than long sleeves. Long hair is best kept under a headdress.
Use pockets as a tool box. If dropped or struck against an object, the screwdriver may injure the body. Even a handkerchief sticking out of the back pocket can wrap around a spinning shaft, pulley, or fan.
Smoke when working near gasoline cleaning solutions or other flammable materials.
Smoke when working near the battery. When the battery is being charged, explosive gas is released from the battery.
Wash your hands with gasoline.
