Abstract:The article takes the entire process of on-site operations in gas engineering as the research object, systematically identifies safety risks in various dimensions such as on-site management, personnel, materials and equipment, processes, special operations, and external environment, deeply analyzes the core causes of risk generation, and combines industry standards and engineering practice to construct a targeted prevention and control system, providing theoretical support and practical reference for gas construction enterprises to optimize on-site safety control and reduce accident rates.
