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

China's "hazardous chemicals directory" of propylene oxide storage regulations

Propylene is an important hazardous chemical, widely used in chemical, pharmaceutical, textile and other industries. Due to its flammable, toxic and potentially carcinogenic properties, China has strict regulatory requirements for its storage and management. This paper will analyze the relevant regulatory requirements for the storage of propylene oxide in detail from the perspective of the List of Hazardous Chemicals, and provide suggestions for relevant enterprises.

1. PROPYLENE OXYPROPYLENE: BASIC PROPERTIES AND HAZARDOUS CHARACTERISTICS

Propylene oxide is a colorless liquid with the properties of an ether, which is flammable and easily oxidized. It is volatile at room temperature, miscible with water, and produces a pungent odor. According to the Directory of Hazardous Chemicals, propylene oxide is classified as a flammable liquid (Category 1) and a toxic substance. Propylene oxide is also classified as a carcinogen, and long-term exposure may pose a serious threat to human health.

Understanding the hazardous properties of propylene oxide is the first step towards compliant storage and a prerequisite for safe production.

2. Propylene Oxide Storage Regulatory Requirements

According to China's "List of Hazardous Chemicals" and relevant laws and regulations, the storage of propylene oxide must meet the following requirements:

1. Storage site requirements Propylene oxide should be stored in a special warehouse for hazardous chemicals, which must be equipped with explosion-proof, fire-proof, leak-proof and other safety facilities. The storage place should be away from fire sources, heat sources and oxidants, ensure good ventilation and avoid direct sunlight.

2. Storage Container Requirements Propylene oxide must be stored in corrosion-resistant, leak-proof containers, such as iron or aluminum containers, and ensure that the container is well sealed. Storage containers should be labeled with hazardous chemicals in accordance with national standards, clearly marked with "flammable liquid", "toxic substances" and other warning information.

3. Storage Limit and Partition Management According to the List of Hazardous Chemicals, the storage amount of propylene oxide shall be strictly controlled and shall not exceed the limit stipulated by relevant laws and regulations. The storage site shall be managed by zones according to the characteristics of hazardous chemicals to ensure that they are stored separately from other hazardous materials (such as strong oxidants, acids, etc.) to avoid chemical reactions.

4. Safety monitoring and emergency measures The place where propylene oxide is stored shall be equipped with a gas detector to monitor the concentration of propylene oxide in real time. In the event of leakage or overflow, emergency measures should be taken immediately, such as the use of explosion-proof exhaust fans for ventilation, and handled by professionals to ensure the safety of surrounding personnel.

3. Propylene Oxide Storage Compliance Recommendations

In order to ensure the compliance of propylene oxide storage, enterprises can start from the following aspects:

1. Establish a sound management system Enterprises should develop a management system for the storage of propylene oxide, clarify the storage process, safe operation procedures and emergency disposal plans, and regularly train managers and operators.

2. Regular safety inspection The storage site should be subject to regular safety inspections, including equipment maintenance, container tightness checks, and emergency plan drills. Rectify problems in time to ensure that the storage environment always meets the requirements of laws and regulations.

3. Use of professional equipment The place where propylene oxide is stored shall be equipped with professional safety equipment, such as explosion-proof lamps and fire extinguishing equipment. Enterprises should regularly maintain and update the equipment to ensure that it is in good working condition.

4. Compliance with environmental and health requirements Propylene oxide shall also be stored in accordance with environmental and occupational health requirements to avoid environmental and employee health hazards. Enterprises should take effective ventilation measures and provide personal protective equipment for employees exposed to propylene oxide.

4. summary and prospect

Propylene oxide is an important hazardous chemical, and its compliance during storage is directly related to the safety of enterprises and the public safety of society. The List of Hazardous Chemicals puts forward clear requirements for the storage of propylene oxide. Enterprises must strictly abide by these regulations and ensure the safety of the storage process from the aspects of storage places, containers, limits and emergency management.

As society pays more attention to the management of hazardous chemicals, the storage requirements for propylene oxide may become more stringent in the future. Enterprises should continue to pay attention to the updates of laws and regulations, and actively adopt advanced technology and management methods to ensure compliance and continuously improve the level of safety production.

The storage of propylene oxide is not only a legal red line, but also a corporate commitment to social responsibility. Only by strictly complying with the requirements of laws and regulations can the sustainable development of the enterprise be realized in ensuring the safety of employees and the public.
