How to travel safely in extreme weather?

Hello! No matter what kind of weather you travel in, you must ensure safety! Extreme weather can be divided into: extreme high temperature, extreme low temperature, extreme drought and extreme precipitation. I don't know what kind of extreme weather you mean. I take extreme high temperature as an example: how to ensure the safety of travel.

1. Open the window for ventilation before entering the car.

Please don't turn on the air conditioner when entering the exposure car. You should first lower all the windows or open the doors, then turn on the big fan to speed up the air circulation, and then close the windows and turn on the air conditioner after three or four minutes, so that the cooling effect is better. In addition, due to the low boiling point of formaldehyde, its release at high temperature is 20% to 30% higher than usual, which makes the formaldehyde in the exposed car increase greatly. Opening the window first can avoid inhaling carcinogenic gases such as formaldehyde and benzene. When parking, you can also lower the glass doors of the four windows by 2~3 cm, and the windows with gaps can dissipate some heat. If it's not troublesome, you can also use a sunshade curtain or a sunshade car cover, which can reduce the temperature inside the car from 8℃ to 10℃.

It is not advisable to turn on the air conditioner for a long time.

Vehicles equipped with air conditioning have better sealing performance. Most people will feel dizzy and tired after staying in this environment for a few hours, and their memory will also decline. That's because when the engine is idling, gasoline will not burn completely and carbon monoxide will be produced. At the same time, the people in the car exhaled a lot of carbon dioxide, which drastically reduced the oxygen in the car; On the other hand, using the air conditioner for a long time after getting on the bus will make the condenser pressure too high and cause losses to the refrigeration system. If the temperature inside the car has reached a comfortable temperature, you can turn off the air conditioner first and then turn it on later. In addition, when the car is idling, it is best not to turn on the air conditioner for a long time, let alone sleep in the car, which may be dangerous. Therefore, the working state of the air conditioner should be properly adjusted, or the window should be opened for ventilation every once in a while.

3. Check and clean the air conditioner frequently.

Air conditioning is the most frequently used component of cars in summer, and it is also the most prone to failure. If the air conditioner of your car doesn't work, please be sure to check whether the air conditioner is short of fluorine, leaking air and freezing lubricating oil. In addition, there are too many accessories on the condenser, the compressor drive belt is loose, and there is too much or too little refrigerant. It's the reason why the air conditioner doesn't cool. Unclean air conditioning systems can also easily infect drivers and passengers with respiratory diseases.

4, driving sunglasses color should not be too dark.

"In summer, the sun shines directly, and the strong light is easy to open your eyes. Many drivers like to wear sunglasses to drive. " The traffic police suggested that you can wear sunglasses, but you should choose light-colored sunglasses.

5. Never drive with slippers.

In hot weather, many drivers even like to put on slippers to drive, which is convenient and cool. The police reminded that "it is dangerous to drive with slippers, which is a traffic violation and is not allowed."
