What's the protection against sand and dust
Eyes
The eye is often the most vulnerable in the sand and dust weather, and if the eye feels alien, it can be washed in a timely manner with fresh water and medical attention should the situation be severe。
Respiratory
When sand and dust weather occurs, air soot and dust particles on their surface are condensed with various toxic and hazardous substances, ranging in diameter from 0. 5 to 5 micrometres, which can be deposited directly through respiratory deposition into human lungs, thus causing respiratory disease. Therefore, enhanced protection measures are important。
Skin
Water rehydration and proper sunscreening are the primary tasks for skin protection in dust and sand weather. The use of wet skin protection is appropriate and too oily to absorb sand。
Therefore, it is recommended that sand and dust weather be kept to a minimum, e. G., when out to wear masks, glasses, veils, etc。
Dust weather guide
Close the windows, shut the out-of-air-conditioning cycle and switch to the inner cycle to prevent sand from entering the vehicle, affecting the driver's sight。
Attention should be paid to the use of the light, which should turn on the headlights, the contour lamps and increase the visibility of the vehicle itself。
Keep your distance, keep an eye on the road, use more horns and be ready to park。
