Explosives storage refers to store gunpowder and explosives, ammunition and explosive. It includes chemical reagent repository used for storing explosives class reagents (e.g. m-diazo phenols, picric acid, etc.). Explosives warehouse type fire chemical product pool, some ammunition plant raw materials library, material supply sector of blasting equipment and mine independent or joint set of explosive, chemical reagents pool of explosives class reagents and large blasting of temporary total explosive class reagents and large blasting of temporary total explosive library and detonators library, etc. Explosives storage under heat, electrical energy, solar energy, and other external energy by combustion and explosion-prone, and explosion powerful, enabling a range of people, animals, architecture, bridges, a tremendous damage or injury. It is therefore necessary to strengthen the explosives warehouse fire management. First, fire risk 1, open fires and fire-induced warehouse explosion. 2. explosives are strong friction, impact, vibration violent reactions, release a large amount of heat and gases, causing the warehouse fire and explosion. 3, excess, obsolete stocks which explosives-caking, moisture, produce an explosion. 4. nature incompatible with explosives mixture of storage, transportation and packaging is damaged. Debris, mixed with human causes. Breaking II, explosion-proof measures 1. explosives warehouse fire safety requirements (1) library site selection ① as explosives explosion of seismic waves, shock waves, shock-liquid, explosive debris, spread to a large extent, the explosion of high temperature will cause a fire, so the explosives warehouse library access must be selected in a far away from cities and Outback open area. Mountain and hilly areas, mining cave built library or use the existing natural terrain for barrier. ② Library site is an important road around. Bridges, ports, airports, important buildings and residential areas must maintain adequate safety distance. At present, domestic on explosives warehouse and surrounding buildings of air shock wave safety distance requirements to the explosives safety equipment factory design and of the explosion safety regulations as a basis for selection. ③ selecting Library site, to prevent explosion pressure relief negative, resulting in losses, you should avoid narrow gully, set at the foot of the mountain or in the Alpine valleys; to avoid affected by earthquake, flood, landslide and debris flow threat should avoid seismic zone. Dry river, near the seasonal rivers and soil loose or vegetation bad security zones within the region; shall not be an additional buildings and other facilities that are not allowed to conduct blasting operations. (2) no excess stockpiling explosives total warehouse area single explosives warehouse allows maximum deposit charge, under the civil explosives factory design security code to perform specific provisions. Use units of storage capacity, to meet the requirements for the three months to consider, according to the surrounding environment make the appropriate changes. (3) rational arrangement of the Treasury as explosives have a characteristic — provides a space for explosive, adjacent Office of explosives will be followed by an explosion, namely "anti-explosive", so the Treasury and treasury stock must be under the charge and inventory of drugs, security facilities to determine the minimum safe distance, anti-explosive or because of improper results from ask chain-type explosions. (4) the Treasury building should be consistent with the requirements of the Treasury should be a single-layer ① building, constructed with rectangular plane. Walls, columns, beams and roof, the use of nonflammable materials. Black powder, nitroglycerine warehouse with brick, light fragile roof. Explosives, ammunition, explosive and fuze warehouse with brick, concrete roof. ② Gunpowder and explosives warehouse should be can't happen spark ground; electrostatic sensitive and explosive library should be used in cement mortar on the secondary ground based conductive rubber. ③ storehouse door yishe double fan doors, door opening to the outside, a width of not less than 1.5 m, no threshold, should not be used hanging doors, side door or doors, need to set the external doors and loading and unloading terminals, both inside and outside the two-story gate towards consistent. Security number of the export of no less than two, to any point within the library to a safety export of distance not greater than 15 meters. Area of less than 220 square metres of warehouse, you can export a security to ensure that any point within a warehouse to a safe distance not greater than exports of 30 m. Windows should be set and the anthem or slats, sunny window to set sun visor or painted on glass, since the paint or frosted glass. Vents to prevent blocking protection, barbed wire, mice and other small animals into the Treasury. ④ store powder absorbs drugs, black powder. Explosive warehouse, indoor walls, floors should be floated should smooth, solid, moisture-proof, anti-corrosion and without cracks. ⑤ the Treasury should maintain good ventilation, suitable temperature. Especially in the hot season, should take appropriate cooling measures. ③ warehouse to half underground warehouse for the best, the library should have ventilation to the ground. (5) setting non-nurse nurses embankment embankment to a certain extent, can serve to block explosion flame, shock wave, explosive debris around the destructive effect of adjacent buildings and withstand explosion on the role of threat to the Treasury, and can greatly reduce the security gaps, and help to save space. On the dike height generally should not be lower than the Treasury eaves, preferably above the roof 1.5 meters; its upper width not less than 1 m, width according to soil still lower (generally from 45 degrees). Earth dike shook line and warehouse walls should be left between 2 ~ 3 metres distance, and drains. (6) to protect the safety of power supply facilities ① warehouse shall not be arbitrarily set up over electrical lines, the warehouse itself and all the electrical equipment shall be eligible products. ② library within the electrical lines shall use pin mounted cables laid along the ground, or copper-core rubber insulation wire wear iron pipe installation, in the entrance separate earthing. ③ the use of overhead line power supply, with the introduction of client should pick the lightning rod, and shall be not less than 50 metres in length of the cable into the Treasury. ④ wire insulation strength not less than 500 Volt, not allowed to pass through the embankment against nurses. Must pass through, you should take to ensure the security and ease of maintenance measures. ⑤ Treasury may use explosion-proof lamps, or the library outside of the lamp and mounted on a wall niche within the Treasury. Small warehouse or night little cargo warehouse, it is best not to pack light. Occasionally at night and leaving goods available torch lighting,You may not use the mobile electric lighting. ③ area within the communications equipment of its conductor insulation strength not less than 250 Volt. (7) installing the necessary lighting equipment ① explosives warehouse must take proper measures to protect against lightning, Thunder and lightning induced directly. Lightning waves of incursions. ② to prevent direct lightning strike, usually in the storeroom fitted around lightning. Warehouse sections must be located within the scope of protection of a lightning rod. ③ Stockpiling detonator, RDX and TNT, explosive and other high power of explosives and a warehouse of explosives should be set and lightning strikes back, lightning lightning protection and lightning protection system of electric wave invasion. (8) equipped with appropriate fire-fighting facilities ① explosives warehouse should set the necessary fire equipment, fire water tank and fire water pipe. Fire water tank to maintain a sufficient amount of water, a large area of water conservation in 100 ~ 200 m ', a smaller area of water conservation in 50-70 m '. Fire water pipe fire water consumption by 20 liter/sec. Fire-fighting equipment should be managed by hand, periodically check to ensure that full use at any time. ② warehouses around the weeds should often hidden for the eradication, elimination of fire danger, fire belt wide weeds trees should also be regularly cleared. (9) the measures enacted strict custody ① explosives warehouse must be equipped with the warehouse owner. Allied custody personnel and the necessary security forces. According to the size of the warehouse or building dedicated fire fire brigade, strengthen the masses obligations daily fire inspection and fire fighting training, just in case. ② establish and improve a set of security system. Such as warehousing registration system, security, censorship, "double" (double custody. Dual-lock, double this reconciliation, double shipping, twin receiving) system, inventory reconciliation from system and security operation system, and so on. ③ piling up explosives should be firm, neat, easy handling. Tank marking of explosives should be facing you, easier to see. ④ explosive box stacking height of not more than 2 meters, each heap not exceeding 770 cartons; detonator container stacking height not exceeding 1.6 meters, each heap must not exceed 300 box. ⑤ the door of the channel width of not less than 1.5 m, stacking and wall distance not less than 0.6 m, stacking is not less distance between ask 1.3 m. (10) the classification system should be stored under various ① explosion sensitivity, classification zhuanku stockpiles. ② all explosives is strictly forbidden and oxidants, spontaneous items. Acid. Alkali. Salt, flammable or combustible materials, metal powder, steel material equivalent library storage. ③ Lui Hg, Pb, the duplication of nitriding diazo-Dinitrobenzene. Detonators, and so a high sensitivity, detonating explosives and explosive devices shall not, in search of detonating cord storage with the library. ④ failure, bad explosive materials and semi-finished products, as well as non-conforming product. Rejects not conforming with the library storage. 2. the storage of explosive substances reagents of fire safety requirements (1) number in 100 grams and is soluble in water of explosives reagents can be stored in a steel Cabinet; quantity of 500 grams is soluble in water of reagents may not separate set storage room, storage of goods can be placed with other reagents with, but should remain: m spacing; quantity of 500 grams, separate storage. (2) storage room, a storage cabinet it is best to set the bottom end, could not be located in or near the warehouse for dangerous goods. Storage room temperature not exceeding 30 ' C, name, specifications, labels and beware of falling off. (3) the custody officer should be regular checks on reagents found that packaging is unqualified, the expired storage. Name unknown, should take appropriate measures in a timely manner.
