What are the basic requirements for electrical safety work?

There are many basic requirements for electrical safety work. To summarize, they mainly include the following aspects:

1. Compliance with rules, regulations and procedures

Fair rules and regulations It is summarized from people's long-term production practice and is an effective measure to ensure safe production. Safety operating procedures, electrical installation procedures, operation management and maintenance inspection systems and other rules and regulations are directly related to safety.

According to different types of work, various safety operating procedures should be established. Such as substation duty safety operation regulations, internal and external line maintenance and inspection safety operation regulations, electrical equipment maintenance safety operation regulations, electrical experiment safety operation regulations, non-professional electricians' handheld power tool safety operation regulations, electric welding safety operation regulations, and electric furnace safety operation regulations , safety operating procedures for crane drivers, etc.

When installing electrical circuits and electrical equipment, you must strictly follow the installation and control procedures, and comply with the requirements of the installation and control procedures during acceptance. This is one of the basic conditions to ensure that the circuits and equipment work in good and safe conditions. one.

According to the characteristics of the environment, an appropriate operation management system and maintenance inspection system should be established. Since equipment defects themselves are potential unsafe factors, equipment damage (such as insulation damage) is often an important cause of personal accidents. Equipment accidents may be accompanied by serious personal accidents (such as electrical equipment catching fire, oil switches exploding), so the operation of the equipment It is very important to manage and maintain inspection systems. Strict implementation of these systems can eliminate hidden dangers and promote the continuous development of production. Operation management and maintenance inspection should pay attention to the principles of combining regularity with regularity, and combining professional teams with production workers.

For certain electrical equipment, a responsibility system for dedicated management should be established. Switchgear, temporary lines, temporary equipment and other equipment that are prone to accidents should be managed by dedicated personnel. Especially for temporary equipment, it is best to clearly stipulate installation requirements, length limits, service life and other items based on the on-site conditions.

The inspection of some items should be carried out without power; some are also allowed to be carried out with power on, and there should be clear regulations on this. In order to ensure the safety of inspection work, especially high-voltage inspection work, necessary safety work systems must be established, such as work ticket systems, work supervision systems, etc.

2. Staffing and safety education

Should be based on the composition and status of the electrical equipment in this part, the composition and quality of the electrical professional staff in this part, and the use of this part. Electrical characteristics and operation characteristics, establish corresponding management institutions, and determine management personnel and management methods. In order to do a good job in electrical safety management, the safety management department, power department (or power department) and other departments must cooperate with each other and arrange dedicated personnel to be responsible for this work. Full-time management personnel should have certain electrical knowledge and electrical safety knowledge, and should formulate safety measure plans based on the actual situation, so that safety work can be carried out in a planned manner and the level of electrical safety can be continuously improved.

New employees entering the factory must receive three-level safety education at the factory, workshop, and production team level. General employees should understand general knowledge about electricity and safe use of electricity; general production workers who use electrical equipment should understand relevant safety regulations in addition to general knowledge; electricians working independently should also understand the installation, use, maintenance, and installation of electrical equipment. Safety requirements during the inspection process, be familiar with electrician safety operating procedures, know how to extinguish electrical fires, and master electric shock first aid skills. Electrical workers must abide by professional ethics, be loyal to professional responsibilities, abide by professional disciplines, unite and cooperate, and provide safe services. To do electrical work, you also need to pass exams and obtain certificates. To meet the above requirements, we need to persist in mass and regular safety education work, such as using broadcasts, pictures, slogans, reports, training classes and other publicity and education methods. At the same time, exchange activities should be carried out in depth to promote the advanced safety organizational measures and safety technical measures of each unit.

3. Safety inspection and establishment of archives

It is best to conduct mass electrical safety inspections once a quarter, and solve problems in a timely manner. Pay special attention to safety before and during the rainy season. examine.

Electrical safety inspection includes checking whether the insulation of electrical equipment is damaged, whether the insulation resistance is qualified, whether the exposed live parts of the equipment have protective facilities; whether the protective zero connection or protective grounding is correct and reliable, and whether the protective device is Comply with the requirements; whether the voltage of portable lamps and local lighting is safe voltage or whether other safety measures have been taken; whether safety appliances and electrical fire-extinguishing equipment are complete; whether the installation of electrical equipment is qualified and whether the installation location is reasonable; whether the system is sound, etc. We must insist on inspections of important electrical equipment such as transformers and make necessary records; we must adhere to principles and meticulousness in the acceptance of newly installed equipment, especially self-made equipment; we must regularly measure the insulation resistance of electrical equipment in use; The grounding resistance of various grounding devices should be measured regularly; safety appliances, lightning arresters, transformer oil and other protective electrical appliances should also be regularly inspected and measured or withstand voltage tests should be conducted.

In order to facilitate work and inspection, high-voltage system diagrams, low-voltage wiring diagrams, plant-wide discharge lines and cable layout diagrams and other drawings, instructions, and record materials should be established. Separate data should be established for important equipment, such as technical specifications, factory test records, installation and commissioning records, etc. Records of each inspection and test should be kept as data for verification. Records of equipment accidents and personal accidents should also be retained as records.
