There are many national regulations on the safety operation procedures of electricians, but they are still impossible to prevent, accidents still occur from time to time, and they are not eliminated because of preventive measures, and some accidents may be reduced because of proper prevention. The danger source of electricians mainly comes from electric shock, and there are individual arc short-circuit burns, and there is also the risk of falling from heights in external operations, and other injuries are relatively few.

High Voltage Electrical HazardIn the event of a short circuit fault or other type of failure, an electrician can suffer serious bodily injury or even death.
Appropriate measures:1Electricians must wear anti-static clothing and electrical safety tools designated by professionals when working;
2.When the electrician handles, maintains and installs electrical equipment, he or she should first find out the wiring status of the circuit breaker and check the status of the circuit;
3.In the process of work, it is necessary to strictly abide by the precautions for accident prevention and avoid contact with the high-voltage power supply as much as possible;
4.When high-voltage electrical equipment fails, it should be delayed to avoid dangerous areas and standardize circuit breaker equipment;
5.Do not manually open the circuit breaker anywhere to prevent fever from receiving electricity;
6.It is necessary to properly use and operate the tools and equipment used to handle high-voltage peripheral work.

The sources of danger for electricians are electric shock, electric shock, fire and **. In order to avoid safety accidents, the following measures should be taken:1
use of formal safety tools and protective equipment; 2.Use the correct way to do it; 3.Regular inspection and maintenance of equipment and tools; 4.
Reasonable lightning, waterproof, dustproof, sound insulation and ventilation measures should be taken in the working area.

1. The prevention and management of electrical safety matters mainly includes:
1. The installation of electrical equipment should meet the requirements of insulation and isolation, and the dismantling of electrical equipment should be completely clean. The metal shell of electrical equipment must be effectively grounded. Electrical workers should correctly use insulated safety tools such as gloves, shoes, pads, clamps, rods and electric detectors.
2. Strengthen the education of all employees to prevent electric shock accidents and improve the awareness of all employees to prevent electric shock; improve the system of safe electricity use; It is strictly forbidden for unlicensed personnel to engage in electrical work; Safety regulations should be strictly implemented when using electrical equipment.
2. Requirements: Protective grounding is to closely connect the conductive part of the voltage to the ground that may be dangerous in the case of a fault with the earth. As long as the size of the protective ground resistance is properly controlled, the voltage of the leakage equipment to the ground can be limited within a safe range.
Unless otherwise specified, all parts of the metal that may exhibit dangerous voltages due to insulation failure or other reasons shall be grounded.
Protective zero connection refers to the interconnection between the metal part of the electrical equipment that is not charged under normal conditions and the protective zero line of the power grid. This safety technical measure is used in three-phase four-wire distribution systems with a voltage of 380 volts and 220 volts directly to ground at the neutral point. The basic function of protection zero connection is that when a phase live part touches the equipment shell, a single relative short circuit of the relative zero line is formed through the equipment shell, and the short-circuit current promotes the overcurrent protection device on the line to act quickly, and the fault part is disconnected from the current to eliminate the danger of electric shock.
3. Suggestions: Do a good job of prevention in view of the high peak of electric shock accidents with seasonal characteristics.
