What is the height of enterprise guardrails required by the National Work Safety Law?

In our actual operation, when the height of the platform, passage, and workplace is less than 2 meters from the datum, the height of the industrial fence should be no less than 0.9m. When the height from the base level is greater than or equal to 2 meters and less than 20 meters, the height of the industrial protective fence should be 1.05m. When the height from the base level is greater than or equal to 20 meters, the height of the industrial fence should not be less than 1.2m.

According to Gb4053.3-2009 "Steel Straight Ladders, Steel Inclined Ladders, Industrial Guardrails" 5.2 Fence height:

1. When the height from the reference plane is less than 2 meters, the protective railings The height shall not be less than 900mm;

2. When the height of the platform, passage and working place is greater than 2 meters and less than 20 meters from the reference plane, the height of the protective railings shall not be less than 1050mm;

3 , when the height from the base level is not less than 20 meters, the height of the platform, passage and workplace protective railings shall not be less than 1200mm.

Note: Some fences are fully enclosed, such as robot workplaces, robot fences, etc. The height of these fences must be customized according to the height and working range of the robot or manipulator.

Extended information:

Maximize the role of the safety guardrail:

1. Platform guardrail height (the upper plane of the handrail is from the ground): 900mm-1200mm;

2. The vertical spacing of guardrail columns is _1200mm, and the vertical spacing of glass guardrail columns is _1000mm;

3. The vertical spacing of guardrail poles is _110mm;

4. The balance distance between the handrail and the upper crossbar is _110mm, and the balance distance between the lower crossbar and the ground is _110mm;

5. Pipe wall requirements: handrails and columns_1.4mm; crossbars_1.2mm; vertical poles_ 1.0mm;

6. Profile finish: Aksu outdoor powder high-temperature electrostatic powder spraying or oxidation electrophoresis coloring production process is used, and the color is designed according to the project;

7. Production process: Adopt Classic buckle rapid assembly production process, no need for welding, wire connection and corner code connection;

8. Technical requirements for glass guardrails: Use tempered laminated safety glass with a thickness of 12mm and an embedded depth of 12mm. The four sides of the glass are made of three Inlaid with EPDM tape;

9. Construction and installation technical requirements: The handrails and wall facades are fixed with aluminum die-cast internal expansion bolts, and the columns and the ground are fixed with internal expansion bolts of aluminum connectors.
