According to the "safety management system" engineering equipment:
1, the first article stipulates that: all kinds of equipment and instruments shall not be overloaded and run with disease, and to achieve the correct use, frequent maintenance, regular maintenance, does not meet the safety requirements of the obsolete equipment, should be planned to update and transformation.
2, Article 2: Electrical equipment and lines should be in line with the relevant national safety regulations. Electrical equipment should be fusible insurance and leakage protection, insulation must be good, and have reliable grounding or zero protection measures; generate a large number of vapors, corrosive gases or dust workplaces, should be used in closed-type electrical equipment;
There is a danger of flammability and explosiveness of the workplace, should be equipped with explosion-proof electrical equipment; wet places and mobile electrical equipment, should be used to safe voltage. Electrical equipment must meet the safety technical requirements of the appropriate level of protection.
3, Article 3 states: the layout of the workplace should be reasonable, keep clean and tidy. Toxic and harmful operations, there must be safety measures.
4, Article IV provides: high temperature, low temperature, humidity, lightning, static electricity and other hazards of the workplace, must take appropriate and effective safety measures.
Two, according to the "Safety Management System" telecommunications lines:
1, Article 1 states: the design, construction and maintenance of telecommunications lines shall comply with the Ministry of Posts and Telecommunications safety and technical regulations. All staff engaged in the construction and maintenance of telecommunication lines and other staff, shall strictly implement the "safety and technical regulations for telecommunication lines".
2. Article 2 stipulates that the construction unit of telecommunication lines must organize construction in accordance with safe construction procedures. Overhead lines, antennas, underground and flat-bottomed cables, underground pipelines and other telecommunications construction projects and the construction environment must accordingly take safety measures. Construction tools and instruments should be qualified, sensitive, safe and reliable. Work at height tools and protective equipment, must be provided by professional manufacturers and management, and often check, regular identification.
3, Article 3 provides that: telecommunications line maintenance to prevent electric shock, falling from a height and fall accidents, line maintenance must first check the solid condition of the root of the line before the pole, the circuit of the power test to confirm the safety of the operation is allowed. Operation should pay close attention to the impact of power lines on communication lines and operational safety, and work in strict accordance with the operating procedures. Not allowed to hire or retain retired workers as line erection work.

Common Standards for Electrical Equipment:
1, Safe voltage standard:
Safe voltage is the voltage without any protective equipment, the human body comes into contact with the various parts of the body's tissues, such as skin, heart, nerves, etc. without any damage. It is often difficult to determine a maximum safe voltage that is perfectly suitable for the human body.
China's regulations 36, 24, 12V three voltage levels for the safety of voltage levels for use in different places. In areas where there is a risk of high-voltage shock, the safe voltage is 36 V. In areas where there is no risk of high-voltage shock, the safe voltage is 24 V. When working in humidity, conductive dust, high temperature and metal containers, 12 V is the safe voltage.
Safe voltage regulations are from the overall consideration, for some special circumstances, some people may not be absolutely safe. It can be seen, even in the provisions of the safe voltage work, but also not careless.
2, the safety distance standard:
Safety distance refers to a variety of working conditions, the charged conductor and the surrounding grounding body, the ground, the different phases of the charged conductor as well as the minimum distance between the staff must be maintained.
The size of the safety distance is closely related to the characteristics of the discharge applied to the conductor and the voltage level. For lightning overvoltage, the safety distance should be decided according to the characteristics of the lightning arrester. For operational overvoltage, the safety distance is decided according to the overvoltage multiplier that may occur in the power grid.
The maximum permissible operating voltage of the power grid can be disregarded because its value will not exceed 110%. The safety distance in various situations in which the electrician's professional regulations provide for action is the credentials that electrician designers, operation and maintenance personnel must comply with in their work.
