4、 Accident handling procedures

Once an environmental pollution accident occurs, the accident situation should be immediately reported to the company. The report content includes the time and location of the accident, a brief description of the accident, the type and number of pollution sources, nature, number of casualties, preliminary estimates of direct economic losses, and emergency measures taken.

After receiving the order, members of the expert group should immediately rush to the scene and provide necessary technical guidance for accident handling based on the type, number, and nature of the pollution source, to prevent the expansion and spread of the accident, and to prevent the occurrence of secondary hazards. We need to organize the safe transfer of important materials and equipment on site, especially flammable, explosive, toxic, and corrosive equipment and appliances.

Members of the on-site command team should organize personal protection based on the degree and scope of harm, terrain and weather conditions, and enter the site to implement emergency measures. It is necessary to quickly clarify the types and nature of pollution accidents, the quantity of pollutants, and the extent of pollution caused. After comprehensive analysis, a scientific pollution disposal plan should be proposed to the special command group in a timely manner. After approval, it should be quickly implemented according to the task division, emergency and disposal procedures and norms, and the handling process and situation should be reported to the command group in a timely manner.

1. On site pollution control

(1) Take effective measures immediately. Cut off pollution sources, isolate pollution areas, and prevent pollution from spreading;

(2) Timely report or evacuate personnel who may be affected by pollution hazards;

(3) Participate in the treatment of individuals at risk.

2. On site investigation and reporting

(1) Survey of pollution accident sites;

(2) Technical investigation and evidence collection;

(3) Environmental monitoring: It is generally required that water pollution be detected within 4 hours, and air pollution be detected within 2 hours to determine the types of pollutants and their potential hazards; Quantitatively detect the concentration, degree, and range of pollutants within 24 hours, and issue a monitoring report; And adopt pollution tracking and monitoring until the pollution accident is handled and the pollution report is lifted.

5、 On site protection

The accident scene must be strictly protected. Everyone participating in rescue and rescue must strictly protect the accident scene. When it is necessary to move objects on site due to rescue, signs, photos, detailed records, and on-site maps must be made, and the main traces and physical evidence on site must be properly preserved.

6、 Organize accident investigation and revise contingency plans

Conduct on-site investigation work, adhere to the principle of seeking truth from facts in accident investigation, and adhere to the "four no let go" principle in accident handling, that is, do not let go until the cause of the accident is identified, do not let go until the person responsible for the accident is dealt with, do not let go until employees are educated, and do not let go until corrective measures are implemented.
