Safety measures for working at height

1. The facilities and equipment in high-altitude operations must be inspected before construction to confirm that they are in good condition before they can be put into use.

2. Climbing and hanging personnel must pass professional technical training and professional examinations, hold a certificate to work, and must undergo regular physical examinations.

3. Safety technical facilities for high altitude operations during construction. When defects and hidden dangers are found, they must be resolved in time; when personal safety is endangered, operations must be stopped.

4. All objects that may fall in the construction site should be removed or fixed first.

5. The materials used in high-altitude operations should be stacked steadily without obstructing passage, loading and unloading. Handy tools should be placed in the tool bag.

6. All workers entering the construction site must wear safety helmets correctly according to regulations.

Grid installation

① When installing the steel grid, the setting of temporary pivots should be taken seriously. The fulcrum and the elevation of the fulcrum should be arranged before installation. The temporary fulcrum should not only make the grid support uniform force and the rods, but also pay attention to the stability of the foundation (scaffolding) of the temporary fulcrum and pay close attention to the normal condition of the fulcrum.

② It is better to use a jack for the support of the temporary fulcrum, so as to ensure the gradual adjustment during the installation process. However, the adjustment of the temporary fulcrum should not only be the adjustment of a certain point, but also consider the uniform force of the surrounding grid frame to prevent individual rods from being deformed or even damaged due to local adjustment.

③ When removing temporary fulcrums, it should be noted that several groups of fulcrums should be lowered synchronously. During the descent, the range of descent should not be too large. It should be gradually divided into sections and stepped down proportionally, or the support should be removed by equal-step descent with each step not greater than 100mm This is conducive to the overall stability, so that the rods will not be deformed, the supports are lowered more uniformly, and the bolts or welding points are also protected.
