What is the warning level of heavy pollution weather?

The emergency warning of heavily polluted weather is divided into three levels from low to high, which are marked with yellow, orange and red respectively, and the red warning is the highest level. In addition to the requirements of the original early warning grading standards, it is also necessary to issue the yellow warning of heavy pollution weather in the Yangtze River Delta region issued by the Yangtze River Delta Regional Air Quality Forecast Center, and the orange warning and red warning of heavy pollution weather in the Yangtze River Delta region issued by the Ministry of Ecology and Environment.

Precautions:

For heavy polluted weather that often occurs in autumn and winter, it is necessary to prevent risks in advance, strengthen the responsibilities of relevant departments, improve the early warning and emergency response capabilities of urban air pollution, and achieve early detection, early reporting and early warning.

Timely emergency response preparation can alleviate the degree of air pollution to a certain extent and shorten the time of heavily polluted weather. Once the possibility of heavy pollution is found, it can effectively organize, respond quickly and control the pollution degree in time. If the monitoring and early warning mechanism is not perfect, it may cause air pollution.
