Towel magic: in the case of fire towel variable gas mask

Towels are our most common household items. What can it do? Wipe your hands, wipe your face, remove dirt and sweat? Don't underestimate this Towel that seems to have only a clean function. In the fire, the inconspicuous little towel can even play a role as a gas mask. Most fires cause casualties because of the inhalation of large amounts of smoke during the escape process. It can be seen that in the fire escape, anti-smoking and anti-virus is a key.

The gas mask is mainly composed of a filter element, a cover body, an eye window, an exhalation communication device, and a headband. The filter element in the gas mask is the most loyal and important guardian on the gas mask, and efficiently removes harmful aerosol particles into the fire scene. Towels can also filter carbon monoxide in the air because of its strong ability to remove smoke, reducing damage to the human respiratory tract. Therefore, when the citizens take refuge in the fire smoke, they can use a towel to cover their mouths and noses, strive for escape time, and find a safe exit and quickly rush out of the fire.

It is reported that the more the number of folded layers of towels, the better the effect of removing smoke. When a fire occurs, it is limited to 8 layers. At this time, the smoke removal rate is about 60%. Moreover, the smoke removal rate increases with time, and after using the 20% off towel for 3 to 4 minutes, the smoke removal rate is 100%. With different humidity towels, the smoke removal rate varies. The higher the water content, the higher the smoke removal rate and the increase of the air resistance. 10%-30% carbon monoxide can be filtered out with a dry towel of 8 fold, and 10%-40% of the wet towel can be filtered by 8 fold. The carbon monoxide, when the water content reaches 3.3 times that of the towel, the gas permeability resistance increases, and the patient's endurance time is about 1 minute and 20 seconds. For towels that are not dense, try to increase the number of layers. At the same time, it is more conducive to self-help to cover your mouth and nose and make the protection area larger. You can't take the towel off the mouth and nose for a moment in the smoke, even if you only take a breath, it will make breathing difficult.
