Definition of special equipment: 1. Special equipment refers to devices and facilities that are related to life safety and pose a high level of risk. Two basic characteristics: one is that it relates to life safety ； Second, it poses a high level of risk. Internationally, it is referred to as “equipment with potential hazards,” “hazardous equipment,” or “equipment with specific hazards.” 2. Principles for inclusion in the **monitoring scope: First, causing harm to a group ； Second, it causes harm to others ； Third, it has a significant social impact. There are 8 types of special equipment that fall under China’s safety supervision regime: 3 types of pressure-bearing equipment, namely boilers, pressure vessels, and pressure pipelines ； ▲Five types in the mechanical and electrical category, namely elevators, lifting machinery, passenger cable cars, amusement facilities, and motor vehicles used on sites (factories). Elevators refer to mechanical and electrical devices that are powered and use a cabin moving along rigid guides or steps moving along fixed tracks to lift or transport people and goods horizontally; these include passenger (cargo) elevators, escalators, and moving walkways. Passenger ropeways refer to electromechanical devices that are power-driven and use flexible ropes to pull carriers such as cabins for transporting passengers. They include aerial tramways, cable cars, and tow ropeways for passenger transport. Large-scale amusement rides refer to facilities used for commercial purposes to carry passengers for entertainment. They are defined as large-scale manned amusement rides whose maximum designed operating linear speed is greater than or equal to 2 m/s, or whose operating height above the ground is greater than or equal to 2 m. Special equipment includes its attached safety accessories, safety protection devices, and facilities related to those safety protection devices. The necessity of safety supervision for special equipment ▲ Boilers, pressure vessels, and pressure pipelines are special pieces of equipment that are widely used in production and daily life; they pose an explosion hazard. ▲Elevators, lifting machinery, passenger cable cars, amusement machines and facilities, and industrial motor vehicles, as special equipment designed for carrying people, can often lead to injury accidents if they malfunction. Under the main supervision system, for the design, manufacturing, installation, maintenance, and modification of special equipment, it is necessary to obtain a license in accordance with the Regulations on the Safety Supervision of Special Equipment before engaging in such activities. Before putting special equipment into use or within 30 days after its deployment, the entity using such equipment shall register it with the department responsible for the safety supervision and management of special equipment. The registration mark shall be placed or attached in a prominent position on such special equipment. The users of special equipment shall, in accordance with the regular inspection requirements specified in the safety technical regulations, submit a request for regular inspection to the special equipment inspection and testing agency one month before the expiration of the valid period for which the safety inspection was approved. Special equipment must be inspected regularly; those who use special equipment that has not undergone regular inspection or has failed such inspections shall be fined up to 20,000 yuan. A fine of 20,000 to 200,000 yuan shall be imposed on those who use pressure vessels that have not undergone regular inspections or have failed such inspections to store hazardous chemicals. The safety accessories, safety protection devices, and measurement and control devices of special equipment must be inspected regularly in accordance with relevant requirements. Personnel engaged in work with special equipment must, in accordance with **relevant regulations**, pass the assessment conducted by the authorities responsible for the safety supervision of special equipment and obtain a certificate for special equipment operators in a standardized format before they can carry out such work or take on related management duties.
