In the chemical industry, hazardous material storage cabinets are commonly seen; they help protect workers from harm. But do you know how to use these hazardous material storage cabinets? Let’s find out together with Weiwei. What is a hazardous chemical storage cabinet? Cabinets used for storing hazardous chemicals such as flammable liquids, combustible liquids, corrosive liquids, toxic substances, and compressed gas cylinders, including cabinets for storing flammable liquids, combustible liquids, corrosive liquids, toxic substances, and compressed gas cylinders. How many types of hazardous chemical storage cabinets are there? Purpose of flammable liquid storage cabinets: Used for storing flammable chemicals. They have a double-layer fire-resistant steel structure, are equipped with anti-static grounding wires and ventilation holes, and can prevent fires and explosions. Common flammable chemicals in laboratories include alcohol, propanol, gasoline, phosphorus-containing compounds, naphthalene and its analogs, sodium amide, diazanilbenzene, and other flammable liquids. http://p8.itc.cn/images01/20201117/88c4b16a807c41fc99e2042c78ffb085.png Purpose of the flammable liquid storage cabinet: It is used for storing flammable chemicals. It features a double-layer fire-resistant steel structure that effectively isolates heat sources, and it has ventilation holes on the sides to facilitate air circulation. Common flammable chemicals in laboratories include dimethyl ether, ethylene oxide, acetaldehyde, ammonia, hydrogen sulfide, carbon disulfide, methane, ethane, ethylene, etc. Purpose of corrosive liquid storage cabinets: Used for storing mildly corrosive chemicals. They feature a unique galvanized sheet coating that provides corrosion resistance and prevents leaks, with ventilation holes on the sides to facilitate air circulation. Commonly used weakly corrosive chemicals in laboratories: These chemicals are solids or liquids that can burn human tissue and cause damage to materials such as metals; they mainly include acids and bases, such as sodium hydroxide, sodium sulfide, sodium acetate, hydrochloric acid, etc. http://p5.itc.cn/images01/20201117/b649da2ac88148078d76b3c65efb77ca.png A storage cabinet for toxic substances is a container used to store such substances. (e.g.: potassium cyanide, sodium cyanide, potassium gold cyanide, malononitrile, phenol, etc.). A compressed gas cylinder storage cabinet is a cabinet used for storing compressed gas cylinders. (Countries such as: hydrogen, nitrogen, argon, etc.) Storage cabinets for flammable gas cylinders should be equipped with automatically interlocked forced exhaust fans; the exhaust ducts must lead outside, and they should be made of metal and grounded. It is also recommended to arrange storage cabinets for flammable and combustible liquid chemicals in this manner. Requirements for on-site safety management of hazardous chemical storage cabinets 1. The user entity shall select storage cabinets that meet the requirements based on the nature and quantity of the hazardous chemicals to be stored. 2. Hazardous chemical storage cabinets or cabinets should be installed separately, away from sources of fire, heat, electricity, and environments where sparks may be generated; no miscellaneous items should be placed within a 1-m radius around them ； When multiple storage cabinets containing hazardous chemicals with similar properties are grouped together, the distance between adjacent storage cabinets should not be less than 150 mm. 3. In the event of leakage or seepage from the packaging containers of hazardous chemicals, it should be dealt with promptly, and they should not be kept in the hazardous chemicals storage cabinets any longer. 4. The anti-static grounding devices for the storage cabinets of flammable and combustible liquids must be in proper working condition; the grounding resistance value of these anti-static devices should be less than 100Ω. Other requirements regarding static electricity protection shall comply with the standards specified in GB 121585. 5. In accordance with the requirements of GB15603, hazardous chemicals should not be stored together with chemicals that are incompatible with them. Special note: Flammable liquids must not be stored in the same hazardous materials cabinet as oxidizers, self-igniting solids, or items that are flammable when exposed to moisture. 6. Hazardous chemical manufacturing enterprises shall, in accordance with the requirements of the Regulations on the Safety Management of Hazardous Chemicals, provide safety data sheets that correspond to the hazardous chemicals they produce, and shall attach or affix safety labels corresponding to the hazardous chemicals inside the packaging to the packaging of such chemicals (including outer packaging). The information contained in the Chemical Safety Data Sheet and the Chemical Safety Label must comply with the requirements of **standards. 7. Operators shall wear appropriate personal protective equipment in accordance with the requirements of GB/T 29510, and relevant records shall be kept when obtaining hazardous chemicals. 8. The storage area for hazardous chemical cabinets shall be equipped with appropriate fire-fighting equipment in accordance with GB 50140. 9. When storing highly toxic hazardous chemicals, it is necessary to comply with the relevant provisions of laws and regulations such as the Regulations on the Safety Management of Hazardous Chemicals (Decree No. 591 of the State Council) and the Measures for the Administration of Licenses for the Purchase and Road Transport of Highly Toxic Chemicals (Decree No. 77 of the Ministry of Public Security). Requirements for the management system of hazardous chemical storage cabinets: 1. The entity using the cabinets shall establish a safety management system for such cabinets. 2. The entity using the cabinets shall develop safety operation procedures for them. 3. Emergency response: (1) The entity using the cabinets shall prepare on-site response plans and emergency cards for handling hazardous chemical storage cabinets in accordance with the requirements of GB/T29639. (2) The user unit shall organize relevant personnel to conduct emergency drills at least once every six months, and keep records of these drills. http://p8.itc.cn/images01/20201117/cb41b05c49d54b30a669b7cd7a049785.png4. Managers require that those in charge of hazardous chemical storage cabinets receive safety training, possess knowledge on the safe use of such chemicals and the ability to handle emergencies related to them; they can only take up their duties after passing an assessment conducted by the entity using these chemicals. 5. Safety inspection and maintenance of hazardous chemicals storage cabinets (1) The user entity should conduct regular safety inspections and maintenance of hazardous chemicals storage cabinets. The inspection items should include, but are not limited to: ① The cabinet’s exterior should be in good condition and free from rust. ②The anti-static grounding device is secure, free from rust, and has clear and complete markings. ③The ventilation openings are in good condition and unobstructed, with clear and complete markings. ④The items are neatly arranged, and the packaging is intact with no damage or leaks. ⑤Calibration of the accuracy of gas concentration detection probes. ⑥The drainage tray is free from damage and leakage. (2) When repairing hazardous chemical storage cabinets, the hazardous chemicals inside must be removed before proceeding with the repairs, and appropriate repair records should be kept. When using hazardous chemicals, it is essential to pay attention to safety measures, ensure that labels are in place, and address any damage or issues promptly before attempting repairs, in order to prevent accidents.
