What are the regulatory requirements for the storage of butanone in China's List of Hazardous Chemicals?

REGULATIONS AND REQUIREMENTS ON STORAGE OF butanone in China's List of Hazardous Chemicals

Methyl Ethyl Ketone (MEK) is a chemical widely used in the manufacture of coatings, resins, adhesives and solvents and is classified as a hazardous chemical because of its flammability and volatility. According to China's "List of Hazardous Chemicals", butanone is listed as a flammable liquid hazardous chemical, and its storage and management have strict requirements. This paper will analyze the regulatory requirements for the storage of butanone in detail from the aspects of regulatory basis, classification characteristics and storage requirements.

1. legal basis and classification characteristics

according to China's List of Hazardous Chemicals, butanone is identified as a flammable liquid and belongs to the category of dangerous goods clearly defined in the Regulations on the Safety Management of Hazardous Chemicals. According to GB 13690-2009 "General Rules for Classification and Hazard Publicity of Chemicals", butanone is classified as a flammable liquid category 2 with a flash point below 23°C and a high fire risk.

The hazardous characteristics of butanone are mainly reflected in the following aspects:

1. flammability after the steam of butanone is mixed with air, it will burn violently in case of open flame or high temperature.
2. Volatile: Butanone will volatilize rapidly at room temperature to form flammable vapor, which increases the potential safety hazard during storage.
3. Environmental and health hazards butanone is irritating to the eyes and respiratory tract, and long-term exposure may cause damage to the nervous system and liver.

Regulatory requirements 2. the storage of butanone

in order to ensure the safety of the storage of butanone, the relevant Chinese regulations put forward strict requirements on the storage site, storage conditions and management measures. The following are the main regulatory requirements for the storage of butanone:

1. REQUIREMENTS FOR STORAGE PLACES Butanone must be stored in hazardous chemical warehouses that meet national standards. The warehouse shall be equipped with safety facilities such as explosion-proof, fire prevention and leakage prevention to ensure good ventilation and avoid direct sunlight and high temperature environment. The storage place should be away from fire and heat sources, and keep a safe distance from other flammable materials.

2. Requirements for storage containers The methyl ethyl ketone must be stored in a special container, such as an iron or aluminum container, and the container should be leak-proof to ensure a good seal. It is forbidden to use containers made of flammable or combustible materials to prevent accidents caused by accidental burning or leakage.

3. Requirements for storage environment The temperature of the storage environment of butanone should be controlled between 15°C and 25°C, and the relative humidity should not exceed 80%. Avoid placing butanone in high temperature, high humidity or strong oxidation environments to prevent chemical reactions or excessive vapor concentrations.

4. Safety protection measures The butanone storage site shall be equipped with fire extinguishers, explosion-proof lamps and other safety facilities, and a combustible gas detection and alarm device shall be installed to monitor the concentration of butanone vapor in the environment in real time. Obvious safety warning signs shall be set up in the storage area, and smoking and open flame shall be prohibited.

5. Emergency treatment measures The storage site shall develop a comprehensive emergency plan to ensure that effective measures can be taken quickly in the event of leakage or fire. The storage area shall be equipped with emergency materials, such as gas masks, protective clothing, etc., to ensure the safety of the staff.

Safety management of 3. butanone storage

in addition to the above regulatory requirements, the storage of butanone requires strict compliance with the following safety management measures:

1. regular inspection and maintenance The tightness and safety of the storage container shall be checked regularly to ensure that the container is free from leakage and damage. Regularly maintain safety facilities, such as gas detection alarm devices and fire extinguishing equipment, to ensure their normal operation.

2. Strict record and identification The stored butanone shall be clearly marked, and the records shall include information such as quantity, batch number and storage date. A sound management system should be established to ensure that the accounts are consistent and to avoid safety problems caused by management omissions.

3. Personnel training and emergency drills The staff of the storage site shall receive professional hazardous chemical safety training and be familiar with the nature of butanone, storage requirements and emergency treatment measures. Organize emergency drills regularly to improve employees' ability to respond to emergencies.

4. Summary

as an important hazardous chemical, butanone must strictly comply with the relevant requirements of China's Hazardous Chemicals List during storage. From the safety of the storage place, the sealing of the container to the temperature and humidity control of the environment, every link needs to be carefully managed. Only through standardized storage and strict management measures can we effectively reduce the safety risk in the storage of butanone and ensure the safety of personnel and the environment.

For practitioners in the chemical industry, being familiar with and strictly implementing the legal requirements for butanone storage is not only a compliance with laws and regulations, but also a manifestation of safe production and corporate responsibility. Through scientific and reasonable storage management, enterprises can minimize the possibility of accidents and improve the overall safety management level.
