There is a safe passage at the construction site. What does it do?

The safe passage at the construction site usually refers to the "head protection shed" set up with scaffolding, safety nets and hard wooden boards at the entrance and exit of the building. The purpose is to prevent objects from falling from the upper part and injuring people. This kind of safety channel can sometimes be set up in areas where lifting is frequent.

1. A protective shed should be erected at the entrance to the main entrance of the building. The width of the shed is larger than that of the road entrance, and each end is 1m longer. The depth dimension should comply with the safety protection range for high-altitude operations.

The falling radius (R) is: when the height of the falling object is 2~5m, R is 3m; when the height of the falling object is 5~15m, R is 4m; when the height of the falling object is 15~15m When 30m, R is 5m; when the height of the falling object is greater than 30m, R is 6m.

2. If the distance between the inside (outside) road edge and the edge of the building (or external scaffolding) is less than the fall radius respectively, a safe passage should be set up.

Extended information:

The fire separation method between the safety passage and other areas is an important feature of the safety passage. The difference in separation methods directly affects the safety level of the safety passage and the use function of the commercial building.

According to the design principles of safe evacuation routes for people, when people are evacuating, each stage is safer than the next, and each step is safer than the next.

It is considered that a more appropriate method is to set up a safe passage between the evacuation stairwell and the outdoor safe area for evacuation in emergency situations. ?

In the event of a fire, people who are in an area with a long evacuation distance can first enter the safe passage and then evacuate from the safe passage to the outdoors; people who are evacuated from upstairs to the first floor can also pass through the safe passage. Evacuate safely to the outdoors.
