During the high-altitude installation and operation of the grid structure, in order to ensure the safety of high-altitude operations, the editor of Jiangsu Huahai Steel Structure believes that three basic protection measures must be taken, referred to as "three treasures" protection. Here is a brief introduction to the "three treasures".

One Safety helmet
All personnel entering the installation site must wear safety helmets correctly. Safety helmets need to be checked frequently. If there are any abnormal damages, cracks, etc., they should be immediately taken back out of use. Each company should inspect and test the safety helmets in use every year in accordance with the standards, and resolutely discard those that do not meet the requirements.
Safety helmets should be used correctly according to the requirements when in use, and high-strength safety helmets with special requirements must be worn when working at high altitudes.
Second Seat belt
Safety belts must be worn when working at a height above 2m without a working platform or formal scaffolding. The various parts on the seat belt shall not be dismantled or replaced at will. The seat belt should be worn as required, and the fixed point of the seat belt should be absolutely safe, and care should be taken not to affect the operator's working range of activities.
Third Safety net
The safety net is an important protective measure for high-altitude operations to ensure safety.
Anyone using a safety net at the installation site must meet the following requirements:
The specifications and materials of the safety net must comply with the national standards of GB5725<Safety Net> and GB1690919 "Dense Mesh Safety Net", and the number of meshes per 100c㎡ area of the dense mesh safety net shall not be less than 2000 meshes. The scaffolding and material lifting frame should be protected by vertical nets.
