High fall accident prevention measures

Safety helmets, safety belts and safety nets are safety “three treasures”. At the job site, personnel should: 1 wear safety helmets for workers entering the job site; 2 high-altitude workers must wear seat belts; 3 safety nets must be provided below the high-altitude operation points.

2. "Protection, entrance, wellhead" protection

The frontier, the hole, the wellhead guardrail, and the protective cover are all installed in most of the operation sites, but there are problems such as insufficient standardization, easy movement or poor effect. Therefore, it is necessary to do all kinds of protection of the edge and the wellhead at the job site. At the same time, it is recommended that some high-rise fall protection facilities should be specially researched and produced. For the protective cover of the hole, some sizes for different hole sizes can be developed. The "safety cover" can neither be moved nor clearly marked. Such safety facilities are very beneficial for preventing falling from high places.

3. Put the nine lanes off

(1) Material is closed, and materials (such as boards, crepe steel, etc.) are selected in strict accordance with the specified quality and specifications.

(9) Inspection and inspection. After all kinds of shelves are set up, it is necessary to check and confirm that the safety is qualified before operation.

4. Surface roof maintenance safety measures

Walking on ceilings and light roofs is very dangerous to walk. Therefore, before operating and walking on the ceiling and light roof, a safety net must be placed under the cushioning board.

Ladder
