[Focus on Safety Production Month] Beijing Emergency Management Bureau Issues Summer Safety Tips for Hazardous Chemicals

　　The increase in high temperatures, thunderstorms, and heavy rain in summer is also a period prone to frequent and severe hazardous chemical safety accidents. To ensure safe production of hazardous chemicals in summer and prevent safety accidents, the Beijing Emergency Management Bureau issues the following safety tips:

　　Part.1

　　Deeply understand the extreme importance of safety production work, firmly establish the concept of safe development, enhance safety awareness, fully implement the main responsibility of enterprises for safety production, strictly enforce all safety management rules and job safety operation procedures, strengthen safety risk control and hidden danger investigation and management, and promptly eliminate safety risks and hazards.

　　Part.2

　　Hazardous chemical production enterprises and chemical enterprises should strengthen process control management during production, strictly prohibit production beyond temperature, pressure, load, and design capacity limits, closely monitor the operating conditions of heat exchange equipment, the operation of cooling water, and abnormal changes in temperature, liquid level, and pressure of main equipment, and anticipate and eliminate safety risks in advance.

　　Part.3

　　Strengthen safety management of hazardous chemical storage, ensure normal operation of safety equipment and facilities such as ventilation, monitoring, control, alarms, anti-static, explosion-proof, and lightning protection. It is strictly forbidden to store hazardous chemicals with mutually incompatible chemical properties together. Toxic chemicals and substances that self-catalyze or react chemically with water must not be stored in damp or leaking warehouses and should have waterproof and moisture-proof measures. Flammable and explosive hazardous chemicals must be stored in cool, ventilated, and dry environments.

　 　Part.4

　　Strengthen safety management of major hazard source tank areas, implement the safety responsibility system for major hazard sources, ensure that cooling spray systems, fire extinguishing systems, emergency shut-off facilities, and alarm devices are intact and effective, guarantee normal use of tank area drainage facilities, and strictly prohibit equipment and facilities from operating with defects.

　　Part.5

　　With increased load in cold storage during summer, ammonia-related refrigeration enterprises should strengthen safety inspections of liquid ammonia sites, check whether storage tank pipelines, valves, pumps, cooling spray devices, toxic gas monitoring, alarms, ventilation, emergency shut-off, and other equipment and facilities are operating normally to prevent leaks and spills.

　　Part.6

　　Schools, research institutions, and technology R&D enterprises using hazardous chemicals should strengthen laboratory hazardous chemical safety management. Experiment personnel must be familiar with the physical and chemical properties of hazardous chemicals and emergency response measures, strictly follow laboratory safety operation procedures, correctly wear personal protective equipment, and ensure reasonable procurement, scientific storage, standardized use, and timely disposal of hazardous chemicals.

　　Part.7

　　Gas cylinder operators and users should classify and store gas cylinders by their hazardous characteristics and zones, ensure storage locations are not near heat sources, prevent exposure to sunlight, rain, and water intrusion, and take anti-tilt measures. Lying down of cylinders is strictly prohibited. Gas cylinder accessories should be complete, and opening or closing cylinder valves should be done by hand or with special tools.

　　Part.8

　　Special attention should be given to management of hot work and special operations such as maintenance and repair, strictly implementing the national standard "Safety Specifications for Special Operations of Hazardous Chemicals," minimizing the frequency of hot work. Before operations, approval procedures must be strictly followed, safety risk identification and analysis conducted, risk control measures implemented, and dedicated personnel assigned for on-site supervision. During high temperatures, outdoor work should be reasonably scheduled to avoid working during peak heat periods as much as possible.

　　Part.9

　　Strictly follow safety operation procedures when loading, unloading, and handling hazardous chemicals. During high temperature periods, avoid transportation and handling of flammable and explosive hazardous chemicals. Stop hazardous chemical loading and unloading operations during thunderstorms. During transportation of hazardous chemicals, operations such as repackaging, filling, and tank transfer are strictly prohibited.

　　Part.10

　　Strengthen risk prevention and control of key hazardous chemical locations during the flood season, focusing on windproof, rainproof, and lightning protection facilities of open and semi-open warehouses to ensure they are in good condition. Conduct inspections of water accumulation areas, low-lying areas, underground facilities, and drainage facilities to promptly eliminate safety hazards.

　　Part.11

　　Enhance emergency duty, improve emergency material reserves, conduct emergency plan drills, increase safety inspections, ensure rapid emergency response and implementation of countermeasures in case of emergencies. Closely monitor weather forecasts, disaster warnings, and other information. In case of production safety accidents and emergencies, handle promptly, conduct scientific rescue, and report to relevant departments as required.
