Classification of battery fire hazards

The fire hazard of production shall be classified into Class A, B, C, D, and E according to factors such as the nature and quantity of the substances used or produced in production.

The fire hazard of stored items shall be classified into Class A, B, C, D, and E according to the nature of the stored items and the amount of combustibles in the stored items.

Production fire

Fire hazard characteristics for the production or use of hazardous substances in the production of the following substances

A 1 liquid with a flash point less than 28 ° C;

2 gas with a lower explosion limit of less than 10%;

3 substances that can decompose at their own temperature or oxidize in the air to cause rapid spontaneous combustion or explosion;

4 Substances that can produce combustible gases and cause combustion or explosion under the action of water or vapor in air at room temperature;

5 acid, heat, impact, friction, catalysis, and flammable inorganic substances such as organic matter or sulfur, a strong oxidant that easily causes burning or explosion;

6 Substances that can cause burning or explosion when exposed to impact, friction or contact with oxidants or organic matter;

7 The operating temperature in the closed equipment is greater than or equal to the production of the self-ignition point of the substance itself.

a liquid having a flash point greater than or equal to 28 ° C but less than 60 ° C;

2 gas with a lower explosion limit of 10% or more;

3 oxidants that are not classified as Class A;

4 Chemical flammable hazardous solids that are not classified as Category A;

5 combustion gas;

6 Floating dust, fiber, and liquid droplets with a flash point of 60 ° C or higher that can form an explosive mixture with air.

B 1 liquid having a flash point of 60 ° C or higher;

2 flammable solids

C 1 processes non-combustible materials and often produces strong radiant heat, sparks or flames at high temperatures or in molten state;

2 using gas, liquid, solid as fuel or burning gas or liquid for various other uses;

3 Use or process the production of difficult-to-burn substances at normal temperature.

D The use or processing of non-combustible materials at room temperature

Fire hazard characteristics of stored items in fire hazard categories

A 1 liquid with a flash point less than 28 ° C;

2 Gas with a lower explosion limit of less than 10%, and by the action of water or water vapor, can produce a solid substance with a lower explosion limit of less than 10% gas;

3 substances that can decompose at their own temperature or oxidize in the air to cause rapid spontaneous combustion or explosion;

4 substances that are exposed to water or steam in the air at normal temperature, can produce flammable gases and cause combustion or explosion;

5 in the presence of acid, heat, impact, friction and flammable inorganic substances such as organic matter or sulfur, a strong oxidant that easily causes burning or explosion;

6 Substances that can cause burning or explosion when exposed to impact, friction or contact with oxidants or organic matter

B 1 liquid having a flash point greater than or equal to 28 ° C but less than 60 ° C;

2 gas with a lower explosion limit of 10% or more;

3 oxidants that are not classified as Class A;

4 Chemical flammable hazardous solids that are not classified as Category A;

5 combustion gas;

6 Contact with air at normal temperature can slowly oxidize, and the accumulated heat does not cause spontaneous combustion.

C 1 liquid having a flash point of 60 ° C or higher;

2 flammable solids

D items difficult to burn

E Non-burning items
