Alcance y aplicabilidad

GB 6442-2025 establishes the technical specifications for the investigation of work safety accidents. It applies to all production safety accident investigations within the People's Republic of China, covering procedures from initial scene examination to final report compilation. This standard is mandatory for all organizations and regulatory bodies involved in accident investigation and compliance auditing.

Requisitos técnicos

The standard mandates a structured approach to accident investigation, encompassing overall requirements, scene investigation, and evidence collection. It requires investigators to preserve the accident scene, identify hazards, and use appropriate personal protective equipment. Investigators must follow strict protocols for documenting scene conditions, extracting physical evidence, and conducting inquiry interviews. Regarding evidence collection, the standard specifies requirements for gathering documentary evidence, physical evidence, and electronic data. It emphasizes the need for chain-of-custody documentation, proper sealing of evidence, and verification of original records. All collected evidence must maintain its integrity without any unauthorized deletion or modification. For accident analysis, the standard outlines methods to determine the direct economic loss and evaluate emergency rescue operations. It requires the identification of direct causes (unsafe conditions and behaviors) and indirect causes (design flaws and management defects). Investigators must classify the accident nature and assign responsibilities based on the causal analysis. Finally, the standard sets forth the requirements for compiling the accident investigation report. The report must accurately detail the accident's basic information, sequence of events, causes, nature, and responsibilities, along with targeted corrective and preventive measures.

Métodos de ensayo

The standard outlines several analytical methods for determining accident causes, including Fault Tree Analysis (accident tree analysis), Event Tree Analysis, the Exclusion Method, Simulation Testing, and Scientific Demonstration. It also details procedures for technical identification and expert evaluations to analyze equipment failures or material defects. These methodologies ensure a rigorous, evidence-based approach to identifying the root causes of the accident.

Preguntas frecuentes
