According to the requirements of the national standard "Safety Regulations for Working at Heights", the work at heights should be stopped in windy weather above level 5, and reliable anti-skid and cold-proof measures should be taken for the work at heights in bad weather such as rain and snow. In case of strong wind above level 5 (inclusive), the hoisting operation of large formwork should be stopped; The hoisting operation of tower crane must be stopped in strong winds above level 6, and the demolition operation shall not be carried out in rain, snow, fog and wind above level 4.

Any operation carried out at a height more than 2m (including 2m) from the reference plane of the falling height that may fall is called aerial work. There are 1 1 kinds of objective factors that directly lead to falling during aerial work. Here are six common situations:

1, the wind speed is above 5 (the wind speed is 8, and the freight yard returns to 0m/s).

2, GBT4200-2008 provisions of secondary or above high temperature operation.

3, the average temperature is less than or equal to 5 degrees Celsius working environment.
