The so-called aerial work refers to the work carried out by people at a height based on a certain position. The national standard GB/T 3608-2008 "Classification of Work at Heights" stipulates: "Any work at heights more than 2m (including 2m) from the reference plane of falling height that may fall is called work at heights." According to this regulation, 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.
