How to prevent electric shock

Common technical measures to prevent electric shock: insulation, screen protection, spacing, grounding, zeroing, installation of leakage protection devices and the use of safe voltage. In the premise of perfecting technical measures, but also strictly comply with the safety procedures, so as to avoid the occurrence of electrocution accidents to the maximum extent possible.

1. Learn about electrical safety and improve your ability to prevent electric shock. Pay attention to the electrical safety distance and do not enter the places where electrical danger signs have been marked. Do not move or touch electrical equipment, especially when the human body is sweating or when the hands and feet are wet, do not operate electrical equipment.

2. In case of electrical equipment failure, do not disassemble it yourself, but find an electrician with an electrician’s license to repair it. When the public power equipment or high-voltage lines fail, call the police to ask the power department to deal with it.

3. Construction according to the design specifications and codes of practice, to ensure the quality of installation. Do not use poor quality, worn out and damaged wires and electrical equipment.

4. Electrical equipment must have protection zero and protection grounding device. And often check to ensure its safety and reliability.

5. According to the line safety load capacity configuration equipment and wire, do not arbitrarily increase the load to prevent overcurrent heating and short circuit, leakage. Do not arbitrarily increase the specifications when replacing the line fuse, and do not use other metal wire instead.

6. When repairing electrical equipment and moving electrical equipment, completely disconnect the power and hang the safety sign of “No closing, someone is working” in a conspicuous position. Equipment and lines that have not experienced power are always considered to have power. The equipment with capacitor should be discharged first, and the movable equipment should be prevented from pulling off the wire.

7. The use of often in contact with the distribution box, switchboard, gate, button, socket, wire, etc. should be intact. Insulation aging, damaged to be replaced in a timely manner, so as to prevent electrocution Oh.

8. Machine tool work lights, portable temporary lighting, to use no more than 36 volts of safety voltage.

9. Thunderstorm should be far away from high-voltage poles, towers and lightning rods. Lightning rod should be intact, and regular testing.

10. the construction of the construction to avoid the protection distance of high-voltage lines. 2004 April 8, Guangdong Jieyang stone more than 20 people lifting iron frame when touching the air of 10,000 volts of high-voltage power lines, resulting in the death of 12 people. Such blood lessons must be borne in mind.

11. High-voltage lines fall to the ground to leave the grounding point of at least 20 meters, such as already within 20 meters, and foot or single-leg jump away from 20 meters to prevent cross-voltage electrocution.

12. When an electrical fire occurs, the power should be cut off immediately, with yellow sand, carbon dioxide fire extinguishers, do not use water or foam fire extinguishers.

If someone is found to be electrocuted, the first thing to do is to get the electrocuted person out of the power source as soon as possible.

Method of disconnection

• If the switch box is nearby, you can immediately pull down the gate or unplug it and disconnect the power.

• such as far from the switch, you should quickly use a well-insulated electrician’s pliers or a dry wooden handle sharp tool (knife, axe, spade, etc.) to cut the wire, or use a dry stick, bamboo pole, hard plastic pipe and other things to quickly pluck the wire away from the electrocution.

• If the scene is not any suitable insulator can be used, rescue workers can also use several layers of dry clothes will be wrapped hands, standing on a dry plank, pull the electrocution of the clothes, so that it is out of power.

• for high-voltage electrocution, should immediately notify the relevant departments to stop the power, or quickly pull down the switch, or by experienced people to take special measures to cut off the power.

B . Symptomatic treatment for electrocution, can be handled according to the following three cases

• for the electrocution after the consciousness, to have a person to take care of, observation, the situation is stable, before the normal activities; for mild coma or breathing weak, can be acupuncture or pinch people in, ten Xuan, Chung Quan and other points, and sent to the hospital for treatment.

• no breathing but heart beating after electrocution, should immediately use mouth-to-mouth artificial respiration; breathing but the heart stopped beating, should immediately carry out extrathoracic cardiac compression method for resuscitation.

(3) such as electrocution heartbeat and breathing have stopped, it is necessary to take measures such as artificial respiration and heart squeeze method alternately to resuscitate.
