Qualified personnel are permitted to perform duties. Simultaneously, safety education for construction workers should be conducted, and staff should be trained on safety operation procedures. They should familiarize themselves with the completed drawings of the building or structure to be demolished, understanding the structural, constructional, and electrical and equipment pipeline conditions. The site supervisor should provide a detailed briefing to the workers involved in the demolition, based on the construction organization design and safety technical regulations.

3. Prior to the demolition project, clear out materials and equipment within the collapse area; disconnect or relocate main utilities such as electrical lines, gas pipes, water pipes, and heating equipment from the building's branches; inspect surrounding dilapidated buildings and reinforce temporarily if necessary; issue public safety announcements to the surrounding community; set off-limit barriers and warning signs around the demolition danger zone; assign personnel to supervise and prohibit unauthorized personnel from entering the construction site.

The demolition of buildings housing chemical hazardous materials requires participation and review by the fire and safety departments, formulation of safety plans, and approval before the implementation of the demolition project.

5. When preparing for controlled blasting demolition, it is imperative to strictly follow the "Blasting Safety Regulations" and undergo blasting design. This includes precise calculations of the blast point, explosive material, dosage, and the爆破 procedure to ensure the safety of surrounding buildings and personnel. Develop technical and safety measures for the blasting demolition work and submit them for approval by superior authorities and the public security department. For buildings that rely on their own weight to collapse, strict calculations must be made to ensure safety. In the calculations, in addition to considering the weight, the degree of instability of the unexploded parts under the influence of wind in adverse directions should also be taken into account.
