Safety FenceSafety Fence Height Standards

1. What is the use of safety fence? 2. What category does the safety guardrail belong to? 3. The vertical steel pipe of the safety fence must not be 4. What is the height of the safety fence at the construction site? What is the use of a safety fence that is higher than that?

The purpose of installing a safety fence is to limit the scope of activities of workers and prevent irrelevant personnel from accidentally entering and workers from causing dangerous access to live equipment during work. Therefore, when performing power outage work, if the safety distance to live parts is less than the following values: 0.1m for 0.4kv and 0.7m for 10kv, a temporary safety fence should be installed between the work site and the live parts. In fact, when the working range of maintenance, testing, adjustment and calibration is larger than 0.7m, temporary safety fences are generally set up on site. The function of the safety fences set up at this time is to prevent maintenance personnel from wandering around and making mistakes, or outsiders. Enter and approach live equipment.

What is the difference between using temporary safety fences for outdoor power outage maintenance equipment and indoor power outage maintenance equipment?

The difference between the use of temporary safety fences for outdoor and indoor power outage maintenance equipment is:

Outdoor: Use temporary safety fences to surround the power outage maintenance equipment (but a maintenance channel should be left). Hang signs on the safety fence with the signs facing inward.

Indoor: 1) Enclose the live operating equipment with a temporary safety fence, and hang a sign on the safety fence with the sign facing inward. For equipment maintenance behind the switchboard (screen), the mesh safety fence door or iron door behind the screen for maintenance should be opened, and the remaining panels running with power should be closed and locked.

2) There should be an iron door or a mesh safety fence behind the switchboard (screen). If there is no door, temporary safety fences should be installed on the left and right panels (screens). What category does the safety guardrail belong to

Safety guardrail belongs to the security category. Safety fences can be divided into soft fences and hard fences. The fences are divided into ordinary polypropylene high-strength wire mesh and polyester fences. Ordinary fences are calculated in meters. Generally, they are made 1 meter high, and the length is determined by the customer. , those higher than one meter can also be customized, ordinary fences (net rope diameter 3.5mm), polyester fences, fences generally need to be equipped with brackets.

The importance of safety guardrails

The insulated safety fence is a high-voltage resistant safety guardrail made of fiberglass to ensure the safety of workers at live work sites such as power plants. Made up of safety guardrails that serve as reminders, insulated safety fences include two types: sheet insulated safety fences and tubular insulated safety fences.

The installation of safety fences is one of the technical measures to ensure the safety of on-site workers. It is mainly used for electrical equipment maintenance, electrical experiments, power distribution maintenance, etc. in power plants and substations. The safety fence is used in conjunction with the warning (sign) sign. The fixing method is adopted according to the actual situation on site. It should be stable and reliable. It is produced by Shijiazhuang Zhongbao Electrical Appliances and Fittings Co., Ltd. The vertical steel pipes of the safety fence must not have cracks, deformations, corrosion and other defects to ensure the stability and safety of the safety fence. The vertical steel pipe of the safety fence should comply with relevant national standards. Its material should be hot-dip galvanized steel pipe. The surface should be free of burrs, stains and other defects. Its outer diameter should meet the design requirements, and it should be installed in accordance with the specified specifications to ensure safety. Fence stability and security. In addition, the vertical steel pipes of the safety fence should be inspected regularly to ensure the integrity of their appearance and internal structure, as well as the reliability and safety of the safety fence. What is the height of the safety fence at the construction site?

The main road sections in the urban area should be equipped with closed enclosure safety fences with a height of not less than 2.5 meters; general road sections should be equipped with closed enclosures with a height of not less than 1.8 meters. . The fence should be strong, stable, clean and beautiful, and public service advertisements and quality, safety and civilized construction slogans should be posted on the fence wall. The fence is equipped with a spray dust suppression system.

Extended information

The details of safe and civilized construction at the construction site are as follows:

1. Gate safety fence: The main entrance and exit of the construction site under construction should be equipped with gates and installed with personnel Face recognition, information-based real-name management system for worker information sharing; the color of the door is harmonious with the surrounding environment; the size of the door can be determined according to the actual situation on site, but it should meet the requirements for vehicle and personnel passage and fire protection; the door frame structure uses appropriate materials Made to ensure durability.

2. Construction site fence: Fences should be set up around the construction site under construction. The fences should be strong, stable, clean and beautiful. Closed fences with a height of not less than 2.5 meters should be set up on major urban sections. Blocks; general road sections should be equipped with closed fences with a height of not less than 1.8 meters. Public service advertisements and slogans promoting quality, safety and civilized construction should be posted on the retaining walls. The wall is equipped with a spray dust suppression system.

3. Surveillance system: Newly started housing construction projects with a contract price of 50 million and above must install a construction site video surveillance system. At least one high-definition camera with zoom and night vision functions must be installed at the entrance and exit of the construction site transport vehicles. The dome camera is required to cover the entrance and exit of the project construction site, the pool and the roads on both sides within a range of 30 meters each. The video surveillance system should share information with construction, administrative law enforcement and other departments.

4. Car washing platform and sedimentation tank: A car washing platform (trough), sedimentation tank and automatic vehicle washing facilities are provided at the entrance and exit of transport vehicles. There is a drainage ditch inside the car washing table (tank) to drain to the sedimentation tank. The car washing table (tank) must have a good drainage system, and drainage ditches are set up around it. The car washing table (tank) should be equipped with a concrete sedimentation tank to ensure smooth drainage and prevent random discharge. ; Ensure that transport vehicles must be mud-free and rinsed before leaving the field.

5. Construction waste disposal: Construction waste and domestic waste at the construction site should be stored in closed garbage stations for centralized classification. Throwing in the air is strictly prohibited and should be cleared and transported to the site in a timely manner. It is strictly prohibited to burn garbage and other types of waste at the construction site. Construction earthwork, slag and construction waste should be transported using closed transport vehicles, and should be driven according to the designated transport route and time, and dumped to a qualified disposal site.
