The fire hazard of production should be classified into categories A, B, C, D, and E based on the properties and quantities of substances used or generated in production, and should comply with the provisions of Table 3.1.1.

The fire hazard of stored items should be classified into categories A, B, C, D, and E based on factors such as the nature of the stored items and the quantity of combustibles in the stored items, and should comply with the provisions of Table 3.1.3.

Table 3.1.1 Classification of Fire Hazards in Production

Production fires

The fire hazard characteristics of the production using or producing the following substances in the hazard category

A liquid with a flash point of less than 28 ℃;

Gas with a lower explosive limit of less than 10%;

Substances that can decompose on their own at room temperature or oxidize in air, leading to rapid spontaneous combustion or explosion;

Substances that can produce flammable gases and cause combustion or explosion when exposed to water or water vapor in the air at room temperature;

5. Strong oxidants that can easily cause combustion or explosion when exposed to acid, heat, impact, friction, catalysis, or flammable inorganic substances such as organic matter or sulfur;

Substances that can cause combustion or explosion when impacted, rubbed, or in contact with oxidants or organic matter;

Production where the operating temperature is greater than or equal to the spontaneous combustion point of the substance itself in a sealed equipment.

Liquid with a flash point greater than or equal to 28 ℃ but less than 60 ℃;

Gas with a lower explosive limit greater than or equal to 10%;

3. Oxidants that do not belong to Class A;

4. Chemical flammable hazardous solids that do not belong to Class A;

5 Combustion supporting gases;

Dust, fibers, and liquid droplets with a flash point greater than or equal to 60 ℃ that can form explosive mixtures with air in a floating state.

Liquid with a flash point greater than or equal to 60 ℃;

2 combustible solids.

The production of non combustible materials that often generate strong radiation heat, sparks, or flames at high temperatures or melting states;

2. Various productions that use gases, liquids, or solids as fuel or burn gases or liquids for other purposes;

Production of difficult to burn substances for use or processing at room temperature.

Production of non combustible substances used or processed at room temperature.

Table 3.1.3 Classification of Fire Hazards for Stored Items

Fire for storing items

Fire hazard characteristics of stored items in disaster hazard categories

A liquid with a flash point of less than 28 ℃;

2. Gases with a lower explosive limit of less than 10%, as well as solid substances that can produce gases with a lower explosive limit of less than 10% under the action of water or water vapor in the air;

Substances that can decompose on their own at room temperature or oxidize in air, leading to rapid spontaneous combustion or explosion;

Substances that can produce flammable gases and cause combustion or explosion when exposed to water or water vapor in the air at room temperature;

5. Strong oxidants that can easily cause combustion or explosion when exposed to acid, heat, impact, friction, or flammable inorganic substances such as organic matter or sulfur;

Substances that can cause combustion or explosion when impacted, rubbed, or in contact with oxidants or organic matter.

Liquid with a flash point greater than or equal to 28 ℃ but less than 60 ℃;

Gas with a lower explosive limit greater than or equal to 10%;

3. Oxidants that do not belong to Class A;

4. Chemical flammable hazardous solids that do not belong to Class A;

5 Combustion supporting gases;

6. Items that can slowly oxidize when in contact with air at room temperature, accumulate heat without dissipating, and cause spontaneous combustion.

Liquid with a flash point greater than or equal to 60 ℃;

2 combustible solids.

Difficult to burn items.

Non combustible items.
