Working at heights more than 2m (including 2m) from the reference plane of falling height that may fall is called working at heights.
First, the national standard GB/T 3608-2008 "Classification of Work at Height" stipulates that:
1. "Any high-altitude operation that is more than 2m (including 2m) from the reference plane of falling height is called high-altitude operation."
2. According to the above regulations, the scope of aerial work in the construction industry is quite extensive. When working in a building, if working on a shelf more than 2m, it belongs to aerial work.
Second, the operation level is high
1, when the height of aerial work is 2-5m, it is called level I aerial work.
2. When the height of high-altitude operation is above 5m to 15m, it is called secondary high-altitude operation.
3. When the height of high-altitude operation is above 15m to 30m, it is called three-level high-altitude operation.
4. When the working height is above 30m, it is called ultra-high operation.
Third, comprehensive prevention and control of falling accidents.
(1) Regular safety publicity and education and safety technical training should be given to personnel engaged in high-altitude operations, so that they can master the laws and hazards of falling accidents from high places, firmly establish safety ideas and have the ability to prevent and control accidents, and strictly enforce safety laws and regulations. When they find themselves or others' abnormal behaviors of illegal operation, or abnormal objects and protective measures related to aerial work, they should replace them in time to meet safety requirements, so as to prevent and control heights.
(2) The physical condition of workers working at heights shall meet the safety requirements. For example, people who are not suitable for aerial work such as hypertension, heart disease, anemia and epilepsy are not allowed to work at altitude; Stop aerial work for those who are tired, depressed and depressed; It is forbidden to work high above the ground after drinking.
