2. Lower explosion limit less than 10 % of the gas

3. Substances that can decompose by themselves at room temperature or oxidize in the air and can cause rapid spontaneous combustion or explosion

4. Under the action of water or water vapor in the air at room temperature , substances that can produce flammable gases and cause combustion or explosion

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

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

Class B material warehouse

1. Liquids with a flash point greater than or equal to 28°C but less than 60°C

< p>2. Gases with a lower explosion limit greater than or equal to 10%

3. Oxidants that do not belong to Class A

4. Chemically flammable and dangerous solids that do not belong to Class A

5. Combustion-supporting gas
