Behind the active response to extreme weather in many places in China, what natural disasters will high temperature weather bring?

First of all, it will lead to disasters such as drought and flood. The risk of wind and hail disaster may lead to over-alert flood; Over-alert floods may occur in tributaries such as Luanhe River in the Pearl River Basin; Regional storms and floods may occur in some rivers in the middle and lower reaches and the Yi Shu Temple water system, and the risk of disasters such as mountain torrents, urban waterlogging, wind and hail is high in rainy areas such as the northeast and northwest of the Qinghai-Tibet Plateau.

Secondly, it will produce heatstroke, induce cardiovascular and cerebrovascular diseases and lead to death. For people with hypertension and cardiovascular and cerebrovascular diseases, sweating is inhibited, heat storage in the body increases, myocardial oxygen consumption increases, and the cardiovascular system is in a state of tension under high temperature, humidity, no wind and low pressure. The sweltering weather will also lead to vasodilation and increased blood viscosity, which is prone to symptoms such as cerebral hemorrhage, cerebral infarction and myocardial infarction, and may lead to death in severe cases. According to the investigation of cardiovascular and cerebrovascular diseases in Beijing, the sultry weather belongs to ischemic stroke.

Besides, it will lead to changeable weather. Strengthen the awareness of heatstroke prevention and cooling, fully understand the safety hazards of extreme weather, and actively do a good job in the deployment and prevention of high temperature weather. Prepare sufficient drinking water and heatstroke prevention and cooling drugs, and distribute heatstroke prevention and cooling drugs such as Ren Dan and herbal tea to various project departments. Reasonable arrangement of construction time, staggered construction, to avoid long-term outdoor work in high temperature period. The dormitory ensures the safe and normal operation of air conditioning and refrigeration equipment, actively investigates potential safety hazards, and it is strictly forbidden to use high-power electrical appliances in the dormitory without permission to avoid safety accidents caused by voltage overload operation.

It is necessary to establish and improve the heatstroke prevention and cooling system and strengthen the physical health examination of employees. Reasonably adjust the working hours of employees, scientifically determine the labor intensity, comprehensively improve the working conditions, carry out training on the hazards of high temperature weather and occupational health protection, and improve the working level of workers in high temperature weather. Emergency plans should be made in time for sudden diseases, and timely treatment should be organized to minimize the harm to workers' health caused by hot weather operations and better protect workers' health under the action of hot weather.
