Abstract: Accidents in confined space operations have always been one of the easily overlooked but
frequent production accidents. This article deeply summarizes and draws lessons from limited space safety
accidents in recent years, combined with the characteristics of limited space operations: starting from
establishing a limited space safety management system, improving the safety literacy and management
concept of enterprises from top to bottom; Simultaneously analyzing the characteristics of the front, middle,
and back operations in confined spaces, and combining them with the characteristics and stages of
accidents, corresponding approval, supervision, and operation requirements were made for the entire
process; Clarified the emergency rescue requirements in case of accidents and selected scientifically
effective labor protection equipment; Mandatory requirements have been made for selection and
equipment, filling the last gap in the process of confined space operations and effectively reducing the
accident rate in confined spaces.
Key words: confined space; safety management system; approval guardianship; protective equipment
