(6) Armored liquids in barrels and bottles should not be arranged in the open air.

2. The fire resistance rating, number of floors and building area of the dangerous goods warehouse

(1) The fire resistance rating, number of floors, and building area of hazardous chemical warehouses shall meet the requirements of the design code for hazardous chemical warehouses.

① The fire resistance rating of high-rise warehouses, high-bay warehouses and silos should not be lower than Class II; steel silos can be used for silos with Class II fire resistance. The warehouse for storing special valuables should have a fire resistance rating of Class I.

② For independently built ammonium nitrate warehouses, calcium carbide warehouses, polyethylene warehouses, urea warehouses, coal blending warehouses, and transit warehouses in stations, wharfs, and airports, the building area may be increased by 1.00 times as specified in this table, but the fire resistance rating shall not lower than level two.

③For warehouses equipped with automatic fire extinguishing equipment, the construction area may be increased by 1.00 times according to the provisions in this table. 

④The storage area for barreled oil products in the oil depot can be implemented according to the current national standard "Code for Design of Oil Depots".

⑤ The maximum permissible building area of the fire compartment of the coal homogenization storage can be 12000m2, but the fire resistance rating should not be lower than Class II.

(2) For cold storage with Class I and II fire resistance, the maximum permissible building area and fire separation area of each warehouse can be implemented in accordance with the relevant provisions of the "Code for Design of Cold Storage".

3. Safety requirements for storage of hazardous chemical substances

The chemical dangerous goods warehouse is a place for storing flammable, explosive and other chemical dangerous goods. The location of the warehouse must be appropriate, the building must meet the requirements of the code, and scientific management should be done to ensure its storage and safekeeping.
