Work with a voltage of up to 1000V should be carried out with a tool with securely insulated handles. Insulation should be carried out in the form of a cover and a non-removable coating based on moisture-resistant, oil-resistant, gasoline-resistant and electrical insulation material. According to the existing rules, the length of the handle insulation should be at least 100 mm, and the insulation of screwdrivers should end at a distance of no more than 10 mm to the end of the blade.

Before you start working with a power tool, you should make sure that: you can punch holes and furrows in walls, ceilings with electrical wiring, perform other work that can damage the insulation coating of cables (install the same water pipes) only after disconnecting them from power sources. If a soldering iron is used during operation, make sure that it is always in the working area of the hood in its working condition. It is impossible to shake off the remains of solder during soldering and its excess is removed on a special stand. During breaks, the electric soldering iron is placed on a special stand with metal brackets.

Risk of electric shock

There are 2 types of electric shock (electric injury and electric shock):

1. Electric shock affects the entire human body, but it does not cause burns, but leads to cardiac arrest.

2. Electrical injury is a lesion of the external parts of the body. It is expressed in the metallization of the skin, in burns and "electric signs".

If a person is electrocuted, you need to take measures to save him as soon as possible. First of all, the person should be released from the action of the current. In order to do this, you need to turn off the electricity or try to throw the wire to the side. Important: when providing first aid to the victim before the ambulance arrives, you should remember about your own safety. Your clothes should be dry, and it is better to put a board under your feet. You should wear rubber gloves on your hands. Otherwise, the rescuer himself will need help.

Repair of electrical appliances should be carried out only after studying the instructions. If some points are unclear or not detailed enough, it is recommended to postpone the repair or call a professional master.
