Compliance overview
Scope and applicability
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.
Technical requirements
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.
Testing methods
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.
FAQs
What types of accidents and industries does GB 6442-2025 apply to?
This standard regulates the investigation procedures for work safety accidents (production safety accidents) within China. It applies to all industries and facilities required to conduct formal accident investigations, covering both general and simplified procedures.
What are the main investigation procedures defined in GB 6442-2025?
The standard outlines two main procedures: the general procedure (involving full scene investigation, evidence collection, analysis, and reporting) and the simplified procedure (applicable for less complex incidents, requiring a minimum of two investigators and streamlined reporting).
Does GB 6442-2025 reference other standards for accident evaluation?
It references several key standards, including GB 6721 for calculating direct economic losses and AQ 9012 for evaluating emergency rescue operations, ensuring a comprehensive assessment of the incident.
