Dangerous goods warehouse

Dangerous goods stores, storage and storage of dangerous goods such as flammable, explosive, toxic, and hazardous materials. According to the nature of subordination and use, it can be divided into two categories, A and B. Category A is a dangerous goods storehouse of commercial warehousing, transportation, and material management departments, and Class B is a dangerous goods storehouse for the company's own use. Among them, dangerous goods storehouses in category A have large reserves and many varieties, so they are dangerous. According to the scale can be divided into three categories: an area of ​​more than 9,000 square meters for large dangerous goods library, an area of ​​550 to 9000 square meters for the medium dangerous goods warehouse, 550 square meters below the small dangerous goods library. According to the structure of dangerous goods stores, it is divided into above-ground dangerous goods stores, underground dangerous goods stores and semi-underground dangerous goods stores.

Location and Structure of Dangerous Goods Stores Dangerous goods stores are classified according to their hazardous characteristics. When selecting a site, the government should select the appropriate construction site according to the overall municipal layout. Generally, a relatively empty area should be selected, away from residential areas and water supply sites. , main traffic routes, farmland, rivers, lakes, etc., are in the downwind position of the local long-term main wind direction. If it is necessary to be in the urban area, the distance between large and medium-sized warehouses of Category A and large-scale warehouses of Category B and residential areas and public facilities should be greater than 150 meters, and the distance between the large-scale and medium-sized warehouses and residential areas and public facilities should be greater than 100 meters and the distance from the highway should be greater than 50 meters. The distance between the large warehouses in the reservoir area is 20 to 40 meters, and the size of the small warehouses is 10 to 40 meters. Flammable commodities should be placed in low-lying areas, and barrels of flammable liquids should be placed in the warehouse. Dangerous goods warehouses should adopt proper building structures according to the types and characteristics of dangerous goods and obtain corresponding permits. At the same time set the appropriate monitoring, ventilation, sun protection, temperature control, fire prevention, fire fighting, explosion-proof, pressure relief, anti-virus, neutralization, moisture, lightning, anti-static, anti-corrosion, anti-leakage or isolation and other safety facilities and equipment.

Management of dangerous goods library 1. establish a strict and perfect management system to ensure the safe storage of dangerous goods, warehouse needs in accordance with the provisions of the laws and regulations of dangerous goods management, according to the characteristics of the particular circumstances of the warehouse and the storage of dangerous goods, to develop Strict warehousing management system for dangerous goods, safety operation procedures, and specific implementation to the responsible person. The warehouse also fulfills the legal and administrative obligations of registration, filing, and reporting in accordance with regulations and requirements of regulatory agencies.

2. Strictly put in the storage system When dangerous goods are put into storage, the warehouse management personnel shall strictly check, carefully check the name of the goods, signs, check the packaging, count the number, and carefully register, and the key dangerous goods shall be implemented with the double receiving and dispatching system. When dangerous goods are delivered to the warehouse, in addition to careful checking of product names, signs, and numbers, warehouse managers must also carefully register the shippers and record the flow of dangerous goods in detail.

3. Select the proper way to store cargo and stacking of dangerous goods, the number must comply with the relevant provisions of the country, choose the appropriate storage location, proper arrangements for appropriate ventilation, shade, water, moisture, temperature-controlled conditions, according to the nature of dangerous goods And the size of stacking rakes and rakes that are reasonably determined by the packaging must be reasonably spaced, and no stacking or other items placed around the fire equipment and distribution boxes should be allowed.

4. Safekeeping and loading and unloading operations During the storage and loading and unloading operations, we must strictly abide by the relevant regulations and operating procedures, reasonably select the loading and unloading apparatus, and properly handle the resumption of operations if the packaging does not meet the operational requirements. The custodial personnel should regularly inspect the variety, quantity and related facilities of dangerous goods, clean the storage yard in time, carry out necessary disinfection treatment, and strictly limit the entry of miscellaneous personnel.

5. Thorough emergency treatment and waste treatment measures When the dangerous goods store encounters an emergency, there must be measures to arrange and handle the command personnel in an emergency, including reporting conditions, on-site emergency treatment, personnel evacuation, blockade of the site, personnel division, etc. . Emergency handling commanders should have relevant professional knowledge and be able to master operational skills.

Warehouses should regularly organize employees to conduct emergency drills. New employees should be trained when they are on duty.

Appropriate disposal measures shall be taken for discarded dangerous goods, packaging containers, etc., such as storage, destruction, neutralization, burying, and other innocent treatment, and hidden dangers shall not be left. The disposal plan should go to the relevant department for record and accept supervision. When a highly toxic dangerous article is stolen, lost or misused, it shall immediately report it to the public security department.

Requirement for safekeeping of dangerous goods storage The storage of dangerous goods is a major area of ​​major security accidents. Therefore, it is imperative to establish and improve effective safety supervision measures for dangerous goods and popularize public safety awareness.

First of all, in the relevant national standards, it is pointed out that the level of security precautions (including technical protection level) should correspond to the risk level of the storage site [site] and be divided into three levels, followed by the first, second and third levels from high to low. Level 1 policing precautions are required for the following risk grades, first level (inclusive). The secondary security precautions requirement applies to the secondary (inclusive) or higher risk level, and the three-level security precautions requirement applies to the three-level risk level. Prevention requirements in which the entity, into place (part) of security doors should meet the requirements of GB17565, the anti-theft security level B (or more); anti-theft locks should meet the requirements GA / T73's; security safes should be consistent with GBl0409 The request. For technical protection requirements, technical prevention areas and areas should be set up with video surveillance systems, intrusion alarm systems, and entrance and exit control systems, which should meet the requirements of GB50348.

Secondly, as a tool to prevent accidents and remove hidden dangers, security products have played an important role in current safety production. At present, hazardous source monitoring, video surveillance, tracking and positioning, disaster prevention and early warning, emergency rescue technologies, and product input and application in security products can all be used in explosion protection, chemical defense, radiation protection, collapse prevention, and traffic accident prevention. To the important role. Emergency safety monitoring and control system, video surveillance systems can, intelligent automated production monitoring equipment organically integrated systems and data acquisition, monitoring and information to achieve data acquisition hazard, dangerous goods, to achieve automatic alarm and alarm handling and dangerous Event reporting function. Also installed in the central region of the hazard security systems, such as an infrared device, possible areas of danger detection, if it is found there is danger, alarm system, then reuse of explosives detectors on-site verification, can effectively avoid Major safety accidents occurred.
