Which areas require LOTO lockout tagout?

According to GB/T 33579-2017 “Mechanical Safety – Methods for Hazard Energy Control – Lockout/Tagout”; GB 30871-2022 “Safety Specifications for Special Operations in Hazardous Chemical Enterprises”; the following places require the implementation of LOTO lockout tagout:
“Chemical Hazardous Materials Enterprises” – Hot Work Operations: During hot work operations, relevant equipment and pipelines need to be isolated from energy to prevent the accidental release of flammable gases or liquids and other hazardous energy, ensuring the safety of the operation. – Confined Space Operations: Before entering confined space operations, the potential hazardous energy sources must be isolated and controlled, such as cutting off power supply, closing valves, etc., and through lockout tagout to prevent accidental startup or release. – Equipment Maintenance Operations: When maintaining hazardous chemical production equipment, the energy sources of the equipment need to be isolated and locked to ensure the safety during the maintenance process.
“Mechanical Manufacturing and Processing Industry” – Equipment Installation, Modification and Repair: During the installation, modification or repair of mechanical equipment, the hazardous energy sources of the equipment need to be isolated and locked to prevent the accidental startup or energy release of the equipment, ensuring the safety of the operators. – Equipment Inspection, Testing and Maintenance: When inspecting, testing or maintaining mechanical equipment, if it is necessary to contact the hazardous parts of the equipment or enter the equipment interior, LOTO lockout tagout must be implemented to ensure the equipment is in a safe state. – Equipment Cleaning and Disassembly: During the cleaning or disassembly of mechanical equipment, the energy sources of the equipment need to be isolated and controlled to prevent the equipment from accidentally starting or releasing energy during the cleaning process.
“Other Industries” – Operations involving hazardous energy: In any operation involving hazardous energy, such as electrical operations, maintenance of hydraulic and pneumatic equipment, etc., LOTO lockout tagout must be implemented to prevent the accidental release of hazardous energy and ensure the safety of the operators. – Operations requiring the removal of equipment protective covers or entering dangerous areas: When operators need to remove the protective covers of equipment or have their entire body or part enter the operation points or dangerous areas of the equipment, LOTO lockout tagout must be implemented.
