After a safety accident occurs in a chemical material production enterprise, a series of emergency response measures need to be taken quickly and orderly to minimize casualties, property losses, and environmental damage. The following are general emergency response steps:

Accident alarm and emergency response

Immediately report to the police: In the event of a safety accident, on-site personnel should immediately dial the emergency alarm number within the company and the local emergency number (119, 120, etc.) to clearly report key information such as the time, location, type, and degree of harm of the accident.

Activate emergency plan: Upon receiving an alarm, the enterprise emergency command center immediately activates the corresponding emergency plan, and according to the responsibilities and procedures specified in the plan, notifies all emergency rescue teams to quickly assemble and rush to the scene of the accident.

Information notification: Timely report the accident situation to enterprise employees, surrounding units, and residents, inform them of possible dangers and precautions, and remind everyone to take preventive measures. At the same time, report the accident situation to the superior supervisory department and relevant regulatory departments to ensure smooth information flow.

On site rescue and disposal

Personnel rescue: Under the premise of ensuring their own safety, rescue personnel quickly enter the scene of the accident, search and rescue trapped personnel, provide emergency medical treatment to the injured, and promptly send them to nearby hospitals for further treatment. For personnel exposed to toxic gases, chemicals, and other hazards, targeted detoxification, decontamination, and other treatments should be carried out.

Disposal of fire, explosion and other accidents: In case of fire or explosion, the fire brigade shall immediately carry out fire fighting and explosion-proof work, and select appropriate extinguishing agents and methods according to the nature of hazardous substances and fire characteristics at the accident site, such as using foam extinguishers to extinguish oil fires, using carbon dioxide extinguishers to extinguish electrical fires, etc. At the same time, it is necessary to prevent the spread of fire and the occurrence of secondary explosions, and to transfer or isolate the surrounding flammable and explosive materials.

Disposal of leakage accidents: For chemical material leakage accidents, the first step is to cut off the leakage source, such as closing valves, stopping equipment operation, etc. Then, based on the properties of the leaked substance, corresponding measures such as plugging, adsorption, and neutralization should be taken to prevent the spread of the leaked substance. For example, for liquid leakage, sandbags, embankments, etc. can be used for containment, and then adsorption materials can be used for adsorption; For gas leaks, it is necessary to strengthen ventilation and reduce gas concentration. During the disposal process, attention should be paid to avoiding the pollution of soil, water and other environments caused by leaked materials.

Isolation and alert of hazardous areas: Set up alert areas around the accident site, set up warning lines, prevent unrelated personnel and vehicles from entering, prevent the accident from escalating and causing unnecessary casualties. At the same time, it is necessary to set up reasonable entrances and exits to ensure that rescue vehicles and personnel can enter and exit smoothly.

Environmental monitoring and protection

Environmental monitoring: Immediately organize professional environmental monitoring personnel to conduct real-time monitoring of the accident site and surrounding environment, including air quality, water quality, soil, etc. Focus on monitoring the concentration and diffusion range of leaked chemical substances and their derivatives in the accident, provide data support for emergency response, and timely grasp the pollution situation of the environment.

Pollution control and cleanup: Based on environmental monitoring results, effective pollution control measures are taken, such as intercepting and purifying polluted water bodies, covering, excavating, and repairing polluted soil. Waste and leaked materials at the accident site should be classified, collected, and disposed of to prevent secondary pollution.

Accident Investigation and Recovery

Accident investigation: After the basic completion of emergency response work, an accident investigation team composed of the enterprise's safety management department, technical experts, relevant regulatory departments, etc. will be established to conduct a comprehensive investigation into the cause, process, and responsibility of the accident. Collect evidence and materials from the accident scene, inquire with relevant personnel, analyze the direct and indirect causes of the accident, determine the responsibility for the accident, and propose corrective measures and suggestions.

Resumption of production: Develop a plan for resuming production while ensuring safety, repair and replace equipment and facilities damaged in accidents, evaluate and adjust production processes, and provide retraining and safety education to employees. During the process of resuming production, strict safety inspections and debugging must be carried out to ensure that all safety measures are implemented properly. Only after passing the acceptance inspection by relevant departments can production be officially resumed.

Summary and improvement: Conduct a comprehensive summary of the emergency response process for accidents, analyze the effectiveness and shortcomings of emergency plans, summarize the experience and lessons learned in emergency rescue work, revise and improve emergency plans, and enhance the enterprise's emergency management level and ability to respond to emergencies.
