Hazardous operations The term “hazardous operations” comes from the **Guidelines for the Identification and Rectification of Accident Hazards in Chemical Enterprises**, issued by the State Administration of Work Safety on August 7, 2012. Section 4.1.6(2) of these Guidelines stipulates that tasks such as hot work, entry into confined spaces, earthwork, temporary power usage, work at heights, line breaking, lifting operations, equipment maintenance, and plugging or removing blind flanges are nine types of tasks considered hazardous. II. Special Operations The term \"special operations\" comes from the \"Safety Regulations for Special Operations in Chemical Production Units.\" These regulations define as special operations those tasks that may arise during equipment maintenance in chemical production units, such as working with fire, entering confined spaces, removing or installing blind flanges, working at heights, lifting operations, using temporary electricity supplies, digging, and cutting off power supplies. Such operations can pose risks to the safety of the operators themselves, other people, as well as surrounding buildings, structures, equipment, and facilities. In other words, the so-called special operations include eight types: hot work, entry into confined spaces, blind flange removal and installation, work at heights, lifting operations, temporary electrical use, earthwork, and line breaking. III. The Eight Major Tasks: The term “Eight Major Tasks” is not strictly a technical term, but rather a general expression used for ease of memory. In 2013, the State Administration of Work Safety issued Order No. 64 – “Ten Provisions for Chemical (**Chemical) Enterprises to Ensure Production Safety,” followed by an “Interpretation of the Provisions,” in which the eight types of operations were mentioned for the first time. The eight types of operations mentioned here refer to lifting operations, hot work, excavation work, circuit interruption work, work at heights, equipment maintenance work, blind flange installation and removal work, and work in confined spaces, among others. Regarding the safety management of these eight types of operations, please study in detail the eight industry standards for work safety: AQ3021-2008, AQ3022-2008, AQ3023-2008, AQ3024-2008, AQ3025-2008, AQ3026-2008, AQ3027-2008, and AQ3028-2008. Whether it’s hazardous work, special work, or the eight types of work, they’re actually pretty much the same. The above provisions are all applicable to **chemical production units or chemical enterprises. In addition to chemical manufacturers and chemical enterprises, many companies in other industries also engage in highly dangerous tasks such as work in confined spaces and work at heights. Therefore, whether there are corresponding **standards or industry standards or not, we recommend that all of the aforementioned 8 or 9 types of operations be treated as \"hazardous operations\" and strictly managed to prevent accidents.
