List of Hazardous Chemicals Subject to Priority Management (First Batch)

The List of Hazardous Chemicals Subject to Priority Management (First Batch) was released on June 21, 2011. It was compiled through comprehensive consideration of factors including chemical accidents occurring domestically since 2002, domestic chemical production patterns, key regulated chemical varieties both domestically and internationally, inherent hazardous properties of chemicals, and major chemical accidents worldwide. The first batch includes a total of 60 hazardous chemicals.
In addition to the listed hazardous chemicals, the following categories of hazardous chemicals at 20°C and standard atmospheric pressure (101.3 kPa) are also subject to priority management:
1. Flammable Gases Category 1 (gases with a lower explosive limit ≤13% or an explosive limit range ≥12%);
2. Flammable liquids, Class 1 (liquids with a closed-cup flash point < 23°C and an initial boiling point ≤ 35°C);
3. Self-igniting liquids, Class 1 (liquids that ignite within 5 minutes of contact with air);
4. Self-igniting solids, Class 1 (solids that ignite within 5 minutes of contact with air);
5. Substances that emit flammable gases when in contact with water, Category 1 (any substance or mixture that reacts violently with water at ambient temperature to produce gases that typically exhibit a tendency to self-ignite, or releases flammable gases at a rate equal to or greater than 10 liters per kilogram of substance per minute);
6. Phosgene and other phosgene-type chemicals.
To implement the requirements of the List, the Safety Measures and Emergency Response Principles for the First Batch of Hazardous Chemicals Subject to Priority Management was also issued. These principles outline safety measures and emergency response protocols for each hazardous chemical in the List of Hazardous Chemicals Subject to Priority Management (First Batch) across five aspects: special warnings, physical and chemical properties, hazard information, safety measures, and emergency response principles.

Hazardous chemicals in the List of Hazardous Chemicals Subject to Priority Management (First Batch) shall be subject to more targeted safety supervision requirements:
1. Production and storage facilities involving key-supervised hazardous chemicals shall, in principle, be designed by Class A-qualified chemical industry design units.
2. Enterprises engaged in the production, storage, use, or operation of key-supervised hazardous chemicals shall be prioritized for inclusion in the annual enforcement inspection plans of local safety supervision departments at all levels for key supervision.
3. Enterprises producing or storing key regulated hazardous chemicals shall equip themselves with fully functional automated control systems tailored to their specific processes, and strictly manage processes and equipment. Production and storage facilities at enterprises where the quantity of key regulated hazardous chemicals used constitutes a major hazard source shall be equipped with automated control systems to enable real-time monitoring of critical parameters such as temperature, pressure, and liquid level.
4. Enterprises producing key-monitored hazardous chemicals shall develop comprehensive and operationally feasible emergency response plans for hazardous chemical accidents in accordance with relevant regulations and product characteristics. They shall be equipped with necessary emergency rescue equipment and devices, enhance emergency drills, and improve emergency response capabilities.
