In recent days, the weather in most parts of the country is not very clear. This is the legendary “ cockroach †. In such weather, it is difficult to avoid a bad mood. For travel, it will also have an impact. The most immediate impact is poor visibility, and the average speed will also drop, leading to traffic congestion. Today we come to the weather and talk about what to watch out for in the fog weather.
PM2.5 has become one of the numbers that people in China care about. What is PM2.5 ? PM2.5 means that the atmosphere contains particles smaller than or equal to 2.5 microns in diameter per cubic meter . This is essentially different from the usual fog! Fog is water and loquat is particulate matter. These particles are components of the Earth's atmospheric composition that contain a small amount of toxic and harmful substances, and have a long residence time in the atmosphere and a long transportation distance.
This particulate matter is also called lung-incorporated particulate matter. The surface is low in dust visibility, but the harm is not negligible. It has a great impact on human health and the quality of the atmospheric environment. The haze in the first two weeks has made the wards of major hospitals become overcrowded, so we must do a good job. Corresponding travel protection.
â— Reduce unnecessary outdoor activities
In this kind of weather, the tiny inhalable particles in the air will have a great negative impact on our respiratory system, especially for children and the elderly. It is recommended that if there is no special urgency, we should minimize it. Outdoor activities, also invited friends to remind the home used to exercise the father and mother, these days to suspend exercise, this air is not as good as not out. In addition, it reminds friends who are on the road to take a mask. This can properly reduce the harm caused to the human body by the air. Now it is popular on the Internet to use a “PM2.5 special mask †in accordance with the current weather conditions . The price is 5 - between 20 yuan
â— For the sake of our sky, please reduce the number of driving trips
The pollution source of this value of PM2.5 mainly comes from industrial production, automobile exhaust, construction, winter heating, coal burning, etc., resulting in the difficulty of the diffusion of harmful substances and a significant drop in air quality. Considering the great environment, we should try our best not to drive in this kind of weather so that we can reduce the air pollution. You may feel that this statement is a little empty. Indeed, from a personal point of view, driving can avoid crowds of people. But here we are talking about poor air quality, not flu, and even if you drive, you will come into contact with it. Air cannot escape from inhalable particles. But at the same time, car exhaust will exacerbate the accumulation of inhalable particles. We can only promote here. The relationship between individuals and society can only be realized by
â— If you have to drive before you go, we need to pay attention to the following items
If we must drive, then we must pay attention to some details, try to reduce the harm of external inhalable particles to us.
1 , try not to drive the window
In such hazy weather, open the windows as little as possible, and do not ventilate by driving windows during driving. Although the side windows and skylights have a negative pressure ventilation effect, it is not recommended here. This will also cause inhalable particles to be carried into the vehicle during driving.
2 , open the inner loop
In addition to the windows, the air-conditioning system is a direct connection with the outside world. Outside air will enter the car through it and affect the air quality in the vehicle. Therefore, in the hazy weather, it is recommended that you set the air conditioning as an internal circulation, which can effectively reduce the entry of inhalable particles. Inside the car For many models equipped with automatic air conditioning , the vehicle will default to the outer cycle when it starts. Do not forget to press the inner cycle switch button to switch it to the inner cycle. Of course, long-term circulation will cause the air in the car to circulate, and if the air in the car is not particularly bad, it is still better than the inhalable particles entering the car.
3 , check the air filter / air filter
After the haze weather has passed, in order to ensure the health of the engine and the people inside the vehicle, we should promptly clean up the air filter and the air-conditioning filter, so as to avoid too many tiny particles in silence caused by poor gas flow on the filter, causing the engine to be boring. " Children " and the air conditioning out of the normal phenomenon. In addition, some models currently on the market are not equipped with original air conditioning filters (there are reserved installation locations, but they are not equipped with filter cartridges). For such model editors, it is recommended that the owner of the vehicle go to a 4S shop or Auto City to purchase a filter cartridge. Significantly reduced inhalable particulate matter into the car.
4 , open the lights
In hazy weather, the visibility of the air will be very poor, and tiny particles floating in the air will obstruct the line of sight. In these days, the domestic road is inextricably linked with more congestion and reduced visibility. Therefore, for the safety of yourself and others, be sure to turn on the lights while driving. At least turn on the width light to indicate the location of other vehicles. If the visibility is very poor, turn on the front and rear fog lights.
5 , adjust the good attitude
Visibility is poor, and the speed is also slow. The traffic is more congested than before . The feeling of “ seeing the flowers in the fog †makes people unable to lift up their spirits and feel bad. In such a case, we must adjust their mentality, do not become impatient, which is very important, since they could not solve, do not unnecessarily anxious, according to the speakers and grab the line stopper such acts can only make the situation worse, The mood of other people is also not good, while increasing the risk of driving
