Specifications for storage and preservation of combustible and explosive goods
Some standard content:
GB179141999
This standard is formulated to regulate the storage management of flammable and explosive items in hazardous chemicals and ensure the safety of flammable and explosive items during storage.
This standard is based on the "Regulations on the Management of Hazardous Chemicals" issued by the State Council and the "Technical Specifications for Commodity Storage and Maintenance" Volume 7 formulated by the State Bureau of Domestic Trade, and combines more than 40 years of practical experience and experimental research results in the storage of such commodities to make specific provisions for the reasonable and safe storage of flammable and explosive items.
Appendix A and Appendix B of this standard are both recommended appendices. This standard was proposed by the State Bureau of Domestic Trade. Drafting unit of this standard: Beijing Commercial Storage and Transportation Company. The main drafters of this standard are Meng Hao, Gong Xiufen, Wu Fengqin, Yu Yuhong, and Zhang Guirong. 1 Scope

6 Protection technology
6 1 Temperature and humidity management
6 1.1 A temperature and humidity meter is set up in the warehouse (a self-recording temperature and humidity meter can be set up in key warehouses), and observation and recording are carried out at the specified time. 6.1.2 According to the different properties of the goods, a humidity management method combining sealing, ventilation and moisture absorption in the warehouse is adopted to strictly control and maintain the temperature in the warehouse to meet the requirements of Table 1. 6.2 Inspection in warehouse
6.2.1 Safety inspection
Carry out safety inspection inside and outside the warehouse every day, check whether flammable materials are cleaned, the firmness of the goods stack and abnormal phenomena, etc. 6.2.2 Quality inspection
According to the nature of the goods, regular inspection of quality in warehouse mainly based on sensory perception is carried out, and 1-2 pieces of each product are randomly inspected, mainly to check the changes of the goods themselves, the changes of the commodity containers, seals, packaging and pads during the storage period. 6.2-2.1 Explosives: Generally, it is not suitable to unpack for inspection + mainly check the outer packaging. Explosive chemicals can be unpacked for inspection. 6.2.2.2 Compressed gas liquefied gas: Use a weighing scale to check its weight. Check whether the cylinder is leaking. Use a balloon to tie the bottle mouth tightly; you can also use a cotton ball to apply dilute hydrochloric acid solution (for nitrogen) or dilute nitrogen water (for nitrogen and chlorine) to the bottle mouth. If there is a lot of smoke, it will immediately produce gas. 6.2.2.3 For flammable liquids, check whether the seal is tight, whether there is volatilization or leakage, and whether there is discoloration, deterioration and precipitation. 6.2.2.4 For flammable solids: check whether there is dissolution (melting), sublimation, discoloration and deterioration. 6.2.2.5 Self-igniting articles and flammable articles that are easily ignited when wet: check whether there is volatilization, condensation, moisture absorption and dissolution. The stabilizer containing stabilizer should be sufficient, otherwise it should be replenished immediately.
6-2.2.6 Oxidizers and organic peroxides: check whether the package seal is tight, whether there is moisture absorption and dissolution, discoloration and deterioration; organic peroxides and stabilizers containing stabilizers should be sufficient, and the seal is tight and effective. GB 17914 —1999
6.2.2.7 Commodities measured by weight should be sampled for weight inspection to control the storage consumption of commodities. 6-2.2.8 After each quality inspection, obvious marks should be made on the outer packaging and records should be kept. 6.2.3 Problem handling of inspection results
6.2.3.1 Record the inspection results item by item and mark them on the outer packaging of the goods. 6.2.3.2 For problems found during the inspection, fill out the notification form for problematic goods in time to notify the stockholder. If the problem is serious or endangers safety, report and notify the stockholder immediately and take emergency measures. 6.2.3.3 For goods with expiration dates, the stockholder should be notified one month before the expiration date. 6.2.3.4 For goods that have exceeded the storage period or have not been shipped out for a long time, a reminder form for goods in stock should be filled out and transferred to the stockholder. 7 Safe operation
7.1 Operators should wear work clothes, gloves, masks and other necessary protective equipment. During operation, they should be handled with care to prevent friction and impact. 7.2 Tools that can produce sparks shall not be used in any operation. The operation site shall be kept away from heat and fire sources. 7.3 Anti-static work clothes shall be worn when handling flammable liquids, and spiked shoes are prohibited. Large barrels shall not flow directly on cement floors. Vehicles entering and leaving the warehouse must wear protective shields, and exhaust gas should not be directly aimed at the warehouse door. 7.4 Barrels of various oxidants must not roll on the cement floor. 7.5 No sorting or modification is allowed in the warehouse. Unpacking, barreling, acceptance and quality inspection must be carried out outside the warehouse. B Storage period
Determined according to the production date and validity period of various commodities. 9 Out of the warehouse
First in first out in the order of production date and batch number. 10 Emergency handling
10.1 See Appendix B (Standard Appendix) for fire extinguishing methods. 10.2 Various items will produce different degrees of toxic gases and toxic smoke during the combustion process. When extinguishing fires and rescuing, you should stand in the upwind direction and wear a gas mask or self-rescue respirator. 10.3 If you find symptoms of poisoning such as hooding, vomiting, breathing difficulties, blue face, etc., leave the scene immediately, move to a place with fresh air or give artificial respiration, and send to hospital for treatment in serious cases.

Min District District District District District District District District District District District District District District District District District District District District District District "Classification" refers to the storage of hazardous chemicals in different areas according to their classification. If there are not many items or the warehouse is insufficient, they can be stored separately because their properties do not conflict with each other; "Disinfection" refers to the storage of two items that do not conflict with each other but are stored in different ways if conditions permit: peroxides such as sodium nitrite should not be stored together with non-oxidizing agents; nitric acid materials such as sodium nitrite with reducing properties should not be stored together with other inorganic oxidizing agents. Where mixed goods are stored, a distance of more than 1m must be left between the stacks and the cargo handles, and the packaging containers must be intact to prevent the two items from coming into contact.
