How to grade high-altitude work?

1. Classification of work at heights: 1. When the working height is 2 meters to 5 meters, it is called first-class high-altitude operation.

2. When the working height exceeds 5m to15m, it is called secondary aerial work.

3. When the working height exceeds15m to 30m, it is called three-level aerial work.

4. When the working height exceeds 30 meters, it is called ultra-high work. Second, aerial work is divided into special aerial work and general aerial work.

1, special aerial work category:

When the gust wind force is level 6 (wind speed is10.8m/s) or above, work at the height with strong wind;

Working at heights with different temperatures in high or low temperature environment;

Working at high altitude during snowfall on snowy days;

Working high above the ground in rainy days;

Outdoor artificial lighting is completely used for aerial work at night;

Work at charged heights when approaching or contacting charged bodies;
