Any product that is used improperly or has substandard quality may pose risks. To avoid these hazards, both manufacturers and users should actively learn about the characteristics of related accidents. The special equipment referred to in the "Regulations on Safety Supervision of Special Equipment" (2009) refers to boilers, pressure vessels, pressure pipelines, elevators, lifting machinery, passenger ropeways, large amusement facilities, and on-site specialized motor vehicles that involve life safety and are highly dangerous.

　　The danger faced by personnel: on-site personnel within the scope of the lifting operation are located in a large metal structure moving area, and ground personnel are always in a danger zone where heavy objects may fall. The normal operation of crane drivers, dismantling and dismantling of cranes, maintenance and repair of high-altitude equipment, and safety inspections all require personnel to face the dangers of high-altitude operations.

　　The time characteristics of general accidents: Accidents may occur at various stages during the product's "lifespan" period, such as electric hoists, chain hoists, and other widely used lifting products during their handling functions, as well as various operating modes in various stages of maintenance, disassembly, transportation, installation, adjustment, and safety inspection. Among them, the most accidents occur during lifting and handling operations and the disassembly and assembly of special equipment. Accidents may occur not only in their abnormal working conditions, but also in normal working conditions.

　　Standardize the use of each type of protective equipment according to its usage requirements. When using special equipment, it must be worn carefully and fully throughout the entire contact time. Workers should make full use of the self-protection of personal protective equipment to reduce the harm brought by the maintenance process.
