Orange high temperature warning! The highest temperature in many places can reach above 37℃. How to deal with the "burning" test?

The Central Meteorological Observatory continued to issue an orange high temperature warning at 06:00 on August 5:

It is predicted that during the day on August 5, high temperatures above 35°C will occur in western Inner Mongolia, the Junggar Basin and southern Xinjiang Basin in Xinjiang, Hexi in Gansu, southern Henan, Anhui, southern Shandong, Jiangsu, Shanghai, most of Hubei, Hunan, Jiangxi, Zhejiang, most of Fujian, central and eastern Guangxi, Guangdong, and most of Hainan Island.

Among them, the highest temperature in parts of western Inner Mongolia, the Junggar Basin and southern Xinjiang Basin in Xinjiang, most of Anhui, most of Jiangsu, most of Shanghai, eastern Hubei, most of Hunan, Jiangxi, Zhejiang, most of Fujian, central and northern Guangdong, and northeastern Guangxi is above 37°C, and the temperature in some local areas such as the Turpan Basin in Xinjiang, southern Anhui, and central and western Zhejiang can reach above 40°C.

There are three levels of high temperature warning signals, represented by yellow, orange and red . The standard for the yellow high temperature warning signal is: the maximum daily temperature will be above 35℃ for three consecutive days. The standard for the orange high temperature warning signal is: the maximum temperature will rise to above 37℃ within 24 hours. The standard for the red high temperature warning signal is: the maximum temperature will rise to above 40℃ within 24 hours.

Hot weather, especially weather with high temperature, high humidity and strong heat radiation that lasts for several days, can cause a series of physiological function changes in the human body, including temperature regulation, water and salt metabolism, circulatory system, digestive system, nervous system, and urinary system.

First, high temperatures can dilate blood vessels in the skin, increase blood flow, increase basal metabolic rate, increase cardiac activity, and lead to faster heart rate and higher blood pressure. These changes will increase the burden on the cardiovascular system. High temperatures can also cause the body to sweat profusely, causing rapid loss of body fluids, resulting in blood concentration, and further increasing the burden on the circulatory system. Once the body is unable to adapt, causing normal physiological functions to be disrupted, it may cause abnormally high body temperature, leading to heat stroke, and may also lead to the deterioration of other chronic diseases such as cardiovascular and cerebrovascular diseases.

Being in a high temperature environment for a long time may also cause the body to metabolize too quickly, resulting in symptoms of hypokalemia or dehydration, and a decrease in one's physical immunity.

How to take measures to prevent heatstroke?

If you have heat stroke, what should you do first aid?

What mistakes should be avoided?

You need to know this heatstroke prevention guide!

In addition, when driving in hot weather, you must be careful to prevent the vehicle from " spontaneously igniting " or " exploding ". Before driving, check whether the high-voltage circuit is short-circuited, leaking, or loose; check whether the carburetor is backfiring, whether the oil line is leaking, whether the exhaust pipe is exploding, whether the tire pressure is too high, etc., to ensure that the vehicle is in good condition.

Summer has always been a high incidence period for poisoning and suffocation accidents in confined space operations . Personnel performing special operations such as aerial operations should take good safety precautions and never give up wearing protective clothing due to hot weather. Confined space operations must be ventilated first, then tested, and then operated to prevent accidents involving poisoning and suffocation. Focus on investigating and actively managing safety risks in production facilities, warehouses, and tank areas involving dangerous chemicals that are flammable and explosive, flammable when wet, and decompose at high temperatures.
