【Hot attention from Chemical Machinery Equipment Network ] On November 9, a fire broke out in a chemical plant in Quzhou, Zhejiang.
The burning produced a large amount of dense smoke, which spread over the sky with the wind.
Subsequently, this incident quickly appeared on the hot search and aroused concerns among netizens about the threat of toxic gases to the environment and human health.
After the accident, firefighting, emergency response, and environmental protection quickly rushed to the scene for emergency rescue and emergency monitoring.
Although there are no casualties or trapped people, there is no clear result about the pollution that netizens are more concerned about.

Although there are no casualties or trapped people, there is no clear result about the pollution that netizens are more concerned about.
Many chemical raw materials are flammable, so chemical plants are a high incidence of explosion and fire accidents.
This year alone, there have been more than one chemical plant accidents in my country, such as a fire accident at a chemical plant in Lianyungang, Jiangsu on April 21, and an explosion at a chemical plant in Tianmen, Hubei Province on September 28.
However, most of the chemical raw materials are toxic, which can easily pollute the surrounding environment after an accident and endanger the health of nearby residents.

Environmental emergencies such as fires or explosions in chemical plants often cause huge damage to the ecological environment in a short period of time and cause more serious social impacts.
Therefore, both enterprises and institutions and all levels of * need to prepare for environmental emergencies.
Incident emergency plan.
Among them, emergency monitoring has a very important position in the plan, and it is the prerequisite and basis for the follow-up control, mitigation and even elimination of the hazards of sudden environmental accidents.

Incident emergency plan.
Among them, emergency monitoring has a very important position in the plan, and it is the prerequisite and basis for the follow-up control, mitigation and even elimination of the hazards of sudden environmental accidents.
When an environmental emergency occurs, the environmental monitoring department needs to conduct a preliminary assessment of the pollution situation, that is, the process of determining the types of pollutants, monitoring items, and the scope of pollution.
The chemical plant that caught fire this time is mainly engaged in organic silicon materials.
In the production and processing process, toxic raw materials such as methyl chloride are used, and toxic wastes are also generated.
After arriving at the scene, the environmental monitoring department needs to determine what harmful substances are in the dense smoke produced by the fire, and where the scope of the pollution spread is mainly.
Then follow the on-site monitoring to determine the concentration of pollutants and their changing trends.

Then follow the on-site monitoring to determine the concentration of pollutants and their changing trends.
Pollutants and monitoring items need to select major pollution factors and characteristic pollutants as monitoring items.
During monitoring, in order to quickly determine the types of pollutants, the degree and scope of pollution, and the development trend of pollution, on-site rapid monitoring methods are usually used for monitoring, such as test strips and portableMonitoring equipment .
Commonly used emergency monitoring equipment includes portable Fourier infrared gas analyzer, portable integrated flue gas analyzer, portable GC-MS combined instrument and atmospheric emergency monitoring vehicle.
At the same time, the surrounding air automatic monitoring station, water quality automatic monitoring station and other fixed environmental monitoring stations can also provide auxiliary data.
Some samples need to be sent to the laboratory for analysis.
However, laboratory analysis also needs to follow an emergency monitoring plan.

In addition to considering the spread of pollution, the sampling points for emergency monitoring also need to pay special attention to the human living environment within the pollution range, such as drinking water sources for residents, air quality in densely populated areas, and farmland soils.
Harmful substances in dense smoke will not only pollute the atmosphere, but also affect soil and water bodies.
Harmful substances in dense smoke will not only pollute the atmosphere, but also affect soil and water bodies.
According to reports, the chemical plant where the fire broke out as early as 2013 had an explosion and caused a fire, but due to the timely extinguishment, the surrounding atmosphere and water environment were not affected by testing.
The scale of the accident is larger, and it has been proved that the combustion material is mainly chlorosilane, and the combustion products are toxic.
What kind of impact it will have on the environment and the lives of residents still needs to wait for the preliminary test results of the environmental monitoring department.

Emergency management of environmental emergencies has always adhered to the principle of putting prevention first and combining prevention with emergency response.
Although emergency monitoring can help relevant departments control pollution and protect the safety of residents, it is better to do preventive work than to remedy it afterwards.
Production safety should not just shout slogans, but also need to be truly implemented.
