1.jpg There are many specialized terms in the field of safe production; it seems like you’ve heard of them all, but you may not necessarily understand them all. Take the term “hazardous work” for example – many people still don’t understand it! Today, we will introduce to you those so-called “hazardous works”. I. Hazardous Operations The term “hazardous operations” comes from the **Guidelines for the Identification and Rectification of Accident Hazards in Hazardous Chemical Enterprises**, issued by the State Administration of Work Safety on August 7, 2012. Section 4.1.6(2) of these Guidelines stipulates that activities 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 operations that are considered hazardous. II. Special Operations The term “special operations” comes from the \"Safety Regulations for Special Operations in Chemical Production Units.\" According to these regulations, operations such as hot work, entry into confined spaces, removal or installation of blind flanges, work at heights, lifting operations, temporary use of electricity, excavation, and disconnection of circuits, which may occur during equipment maintenance in chemical production units, and that could pose a risk to the safety of the operators themselves, other people, as well as surrounding buildings, structures, equipment, and facilities, are considered special operations. 　　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 power usage, earthwork, and line cutting. III. The Eight Major Tasks The term “Eight Major Tasks” is not a technical term in the strict sense, 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 (Hazardous Chemicals) 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.
