Go to the training center under the former Safety Supervision Bureau of Huizhou Local Safety Supervision Administration. Relevant information must be registered in a qualified training institution to participate in the training, because some personnel engaged in aerial work or climbing work directly go to the emergency management office or emergency management bureau to ask, but it is impossible, because this unit does not directly accept students' registration, and it needs safety education and training in the research and training center under the unit before entering the examination. Aerial work refers to any work that may fall from a height of more than 2m (including 2m) from the reference plane of falling height. Aerial work is a special kind of work, which has certain dangers.
