Structural collapse班前安全会讲稿

它是什么

Walls, frames, floors, ceilings, shafts, platforms or temporary works that give way or move unexpectedly during construction, demolition or alteration.

要检查的控制措施，最有效的排在前面

1. Have an engineer assess the structure and the work sequence before demolition or alteration, and follow their written method.
2. Design and install temporary works, such as props, bracing, shoring and formwork, to the engineer's plan and have them checked before anyone works near them.
3. Do not remove, move or alter props, braces or load-bearing elements without engineering approval, and tag temporary works so tampering is obvious.
4. Set exclusion zones around structures at risk of collapse, and keep people and plant out of the fall zone.
5. Inspect structures and temporary works at the start of each shift and after wind, rain, impact or vibration, and stop work if anything has moved or cracked.
6. Limit loads on floors, roofs and platforms to their rated capacity, and keep stored materials and plant away from unsupported edges and walls.

给工人的问题

1. 今天这项工作中，哪里可能会遇到structural collapse？
2. 最有效的控制措施是：“Have an engineer assess the structure and the work sequence before demolition or alteration, and follow their written method”。我们这里能做到吗？如果不能，为什么？
3. 这个工地上有哪些针对structural collapse的控制措施缺失或不起作用？
4. 你会在什么情况下因为structural collapse停工？你会告诉谁？
5. 在这项工作中，我们怎么报告危险、险情或事故？
