1.1 Casualty accidents
refers to personal injury (hereinafter referred to as injury) and acute poisoning (hereinafter referred to as poisoning) occurring to enterprise employees during the production and labor process. 1.2 Lost working days
refers to the working time of the injured person who is disabled.
1.3 Temporary disabling injury
refers to the injury that temporarily prevents the injured and poisoned person from working in the original position. 1.4 Permanent partial disabling injury
refers to the injury that causes the irreversible loss of the functions of the limbs or certain organs of the injured and poisoned person. 1.5 Permanent total disability injury

3 Injury analysis
3.1 Injured part
GB6441—86
Refers to the injured part of the body (see Appendix A Table A1 for classification). 3.2 Nature of injury
Refers to the type of human injury. The principles of determination are: a: The physical condition at the time of injury should be taken as the main factor, and the possible sequelae after recovery should be comprehensively analyzed and determined; b. Multiple injuries should be classified according to the most serious injury. When it is impossible to determine, it should be identified as "multiple injuries" (see Appendix A Table A2 for classification). 3.3 Causal objects
Objects and substances that cause accidents are called causal objects (see Appendix A Table A3 for classification). 3.4 Harmful objects
refer to objects or substances that directly cause injuries and poisoning (see Appendix A Table A4 for classification). 3.5 Injury methods
refer to the methods in which harmful objects come into contact with the human body (see Appendix A Table A5 for classification). 3.6 Unsafe conditions
refer to material conditions that can lead to accidents (see Appendix A Table A6 for classification). 3.7 Unsafe behaviors
refer to human errors that can cause accidents (see Appendix A Table A7 for classification). 4 Classification of injury severity
4.1 Minor injury
refers to disabling injuries with a loss of working days less than 105 days. 4.2 Severe injury
refers to disabling injuries with a loss of working days equal to or exceeding 105 days as specified in the table in Appendix B. 4.3 Death
5 Classification of accident severity
5.1 Minor injury accident
refers to an accident with only minor injuries.
5.2 Severe injury accident
refers to an accident with severe injuries but no deaths.
5.3 Death accident
a. Major casualty accident
refers to an accident with 1 to 2 deaths in one accident. b.
Extremely major casualty accident
refers to an accident with 3 or more deaths (including 3) in one accident. 6
Calculation method of industrial accident
Applicable to enterprises and the calculation methods used when provinces, cities and counties report industrial accidents: 6.1 Mortality rate per thousand
Indicates the number of deaths caused by industrial accidents per thousand employees in a certain period. Calculated according to formula (1), mortality rate per thousand =
6.2 Serious injury rate per thousand
Number of deaths
Average number of employees
GB6441-86
Indicates the number of serious injuries caused by industrial accidents per thousand employees in a certain period. Calculated according to formula (2): Serious injury rate per thousand
Number of serious injuries
Average number of employees
Applicable to the calculation methods used for statistical analysis of accidents within industries and enterprises: 6.3 Injury frequency
（2）
Indicates the number of people injured by accidents per million working hours in a certain period. The number of injured refers to the sum of the number of minor injuries, serious injuries and deaths. Calculated according to formula (3): 5
Injury rate per million working hours (A)
6.4Injury severity rate
Number of injured persons
Actual total working hours
Indicates the number of lost working days caused by accidents per million working hours in a certain period. Calculated according to formula (4): Injury severity rate (B) = -Total lost working hours × 10 0Actual total working hours
6.5Average injury severity rate
Indicates the average lost working days per person injured. Calculated according to formula (5): Average injury severity rate (N) =
B, total lost working hours
Number of injured persons
The calculation methods applicable to industries and enterprises using tons and cubic meters of output as calculation units are: 6.6 The mortality rate calculated by product and output is calculated using formula (6) and formula (7): Mortality rate per million tons =
Number of deaths
Actual output (t)
Mortality rate per ten thousand meters of wood =
Number of deaths
Wood output (m3)×104.
