Classification and Coding of Work Safety Accidents
1 Scope
This document specifies the classification and type coding of work safety accidents and describes the calculation methods for relative statistical indicators.
This document applies to the classification and statistical analysis of work safety accidents.
Note: "Work safety accidents" in this document are referred to as "accidents".

3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
First Induced Reason
In an accident where two or more causes exist simultaneously, the cause that first appears or provides the condition for other causes to function.
4 Accident Classification
4.1 Classification by Basic Accident Type
4.1.1 Classification Principles
The basic accident types are divided according to the following principles:
a)Based on the direct cause of the accident; the direct cause is analyzed according to 7.3 of GB 6442-2025;
b)b) For a single accident, determine the basic accident type according to the description in Table 1, based on the accident process and characteristics;
c) When an accident simultaneously exhibits characteristics of multiple accident types or occurs in a chain, classify the basic accident type successively based on the first induced reason that caused the accident and the severity of harm.
4.1.2 Basic Accident Types
The names and descriptions of basic accident types are shown in Table 1.

8 Burns and Scalds Accident caused by high-temperature substances, hot objects, or chemicals acting on the human body, resulting in casualties.
9 Fire Accident caused by uncontrolled combustion in time or space.
10 Falling from Height Accident caused by a fall during work at height.
11 Fall/Slip Accident caused by falling or tripping to a non-liquid or non-liquid-like substance reference level during non-work-at-height activities.
12 Collapse Accident caused by the collapse, toppling, or overturning of buildings, structures, stacked materials, etc., due to external forces, gravity, or environmental effects exceeding their strength limits or due to structural stability failure.
13 Water Hazard Accident caused by surface water or groundwater entering the production/work area uncontrollably due to inadequate water prevention and control measures.
14 Vessel Explosion Accident caused by explosion of various types of vessels due to quality defects, improper use, or improper maintenance.
15 Pipeline Explosion Accident caused by explosion of various types of pipelines due to quality defects, improper use, or improper maintenance.
16 Flammable Gas Explosion Accident caused by explosion when a flammable gas forms an explosive mixture with air (oxygen or other oxidizing gases) and encounters an ignition source.
17 Flammable Liquid Vapor Explosion Accident caused by explosion when vapor of a flammable liquid forms an explosive mixture with air (oxygen or other oxidizing gases) and encounters an ignition source.
18 Dust Explosion Accident caused by explosion when dust forms an explosive mixture with air (oxygen or other oxidizing gases) and encounters an ignition source.
19 Civil Explosive Explosion Accident caused by explosion of civil explosives during production, operation, storage, transportation, or use.
20 Fireworks and Firecrackers Explosion Accident caused by explosion of fireworks and firecrackers during production, operation, storage, transportation, or discharge.
21 Other Flammable Solid Explosion Accident caused by explosion of flammable solids other than dust, civil explosives, and fireworks and firecrackers.
22 High-Temperature Melt Explosion Accident caused by explosion when high-temperature melt encounters water.
23 Poisoning Accident of acute poisoning caused by ingestion through the digestive or respiratory system or skin contact with toxic substances.
