In recent days, there have been strong snowfalls in Inner Mongolia, Northeast China, North China and other places, including heavy snow to heavy snow in Shenyang, Dalian, Anshan, Jinzhou and other places. According to the data released by the meteorological department of Liaoning Province, from 8:00 on the 6th to 4:00 p.m. on the 9th, the average precipitation of 62 meteorological stations in Liaoning was 41 mm. The maximum snowfall and the maximum hourly snowfall appeared at Anshan Station, 80.3 mm and 10.6 mm respectively. In such extreme weather, in some cities such as Anshan, Liaoning Province, local residents still go to work as usual and encounter various difficulties and even accidents on their way to work. Due to the blizzard, the buses in Anshan were shut down. People dressed in all kinds of cotton padded clothes and down jackets lined up in the street to face the blizzard and walked slowly forward. Some hats were blown away, some "glided" and others fell... Some employees walked for three and a half hours to arrive at the company for work. It was almost noon at this time. In fact, in extreme weather conditions, people should not go to work or work at home for the sake of health, life safety and work efficiency. Online work during the epidemic is already an acceptable way of work for all parties. Unfortunately, the current national regulations do not specify that work can be stopped in snowstorm weather. The emergency notice on strengthening the safety protection of important urban infrastructure issued by the national development and Reform Commission points out that in case of extreme weather and other extraordinary circumstances, we should resolutely and immediately start the highest level response, such as suspension of school, suspension of work, suspension of business and suspension of work. However, the notice is only a guiding opinion, not mandatory, and does not specify what is extreme weather. At present, only some cities in the south, such as the guidelines for public defense against meteorological disasters in Shenzhen (for Trial Implementation), have relevant specific measures. However, extreme weather is not just storms and rainstorms. Extreme weather events refer to rare meteorological events in history that occur in a certain area within a certain period of time, and the probability of occurrence is usually less than 5% or 10%, including rainstorm, typhoon, strong cold wave, Blizzard, hail, tornado, dust storm, heavy fog, long-term drought, etc. At present, the wind can stop work and the rain can stop work. Under the snowstorm, all localities can also adjust and treat flexibly according to the local actual situation, so as to protect workers. There are four kinds of blizzard warning signals: blue, yellow, orange and red. The red warning standard of Blizzard is that the snowfall will reach more than 15mm within 6 hours, or it has reached more than 15mm and the snowfall continues, which may or has had a great impact on traffic or agriculture and animal husbandry. The red warning of Blizzard only requires suspension of classes and business (except for special industries) when necessary. However, from the perspective of facts and logic, Blizzard extreme weather will also cause great harm. In this blizzard, the average precipitation recorded by 62 meteorological stations in Liaoning is 41 mm (snowfall is converted into rainfall). The maximum snowfall and the maximum hourly snowfall appear in Anshan Station, 80.3 mm and 10.6 mm respectively, which has reached the standard of heavy Blizzard and extra heavy blizzard, and other risk factors are added, such as strong wind, freezing, etc. Before the arrival of Blizzard, Anshan City started the blizzard level III early warning. With the continuous intensification of cooling, the early warning level was upgraded twice and finally upgraded to level I (especially serious) early warning. However, in addition to the suspension of primary and secondary schools, the suspension of the whole city has not been implemented. The Blizzard has also been handled flexibly in some places according to the environmental characteristics. For example, Jilin Changchun issued a number of emergency measures. On November 8, classes in primary and secondary schools and kindergartens in the urban compulsory education stage were suspended, and classes in senior high schools were not suspended; In addition to the organs, enterprises and institutions that directly guarantee the operation of the city, the organs and institutions implement a flexible work system; The production of coal mines was suspended from 0:00 to 16:00 on the 8th... This means that in the case of Blizzard and heavy blizzard, most workers can not go to work except for those who maintain the operation of the city, which is the respect and protection of health and life. According to the actual situation, in addition to typhoon and rainstorm, extreme weather should also include blizzard, hail, tornado, dust storm, fog and strong cold wave. The state should unify standards and classify these extreme weather into the scope of work stoppage and work stoppage. All localities can also protect the health and life safety of more people in a wider range according to the local actual situation. (Xinhua News Agency)
