I. What height is considered high-altitude work
The answer to the question "How high is considered truly high?" varies from person to person. However, for high-altitude work, there are strict regulations. High-altitude work, also known as high-altitude operations, is defined in the "National Standard of the People's Republic of China GB/T3608-2008" as "Any operation carried out at a height of 2 meters or more (including 2 meters) above the reference level where there is a possibility of falling" All are referred to as high-altitude work. "
Ii. Reference Plane for Fall Height
This is a rather professional term. The horizontal plane of the landing point of the fall is called the reference plane of the fall height. In high-altitude operations, the lowest point where the operation position may fall is the landing point of that operation position.
Iii. Special high-altitude operations include the following categories
High-altitude work carried out when the gust force exceeds level six (wind speed 10.8m/s) is called strong wind high-altitude work.
2. High-altitude work carried out in high-temperature or low-temperature environments is called high-altitude work at abnormal temperatures.
3. High-altitude work carried out during snowfall is called high-altitude work on snowy days.
4. High-altitude work carried out during rainfall is called high-altitude work in rainy days.
5. High-altitude work carried out outdoors with artificial lighting is called night-time high-altitude work.
6. High-altitude work carried out under conditions of proximity or contact with live objects is collectively referred to as high-altitude work with live electricity.
7. High-altitude operations carried out without a foothold or without a reliable foothold are collectively referred to as suspended high-altitude operations.
8. High-altitude operations carried out to rescue various sudden disasters and accidents are called rescue high-altitude operations.
