Why should a wet towel cover your nose and mouth when you are in a fire or a fire?
As fire occurs, most of the smoke is concentrated in the upper space, so in the escape process, you should try to keep your body close to the ground, crawl or bend forward.
As fire smoke has high temperature and high toxicity, once inhaled, it is easy to cause burns or poisoning of the respiratory system, so the wet towel is used to cover the nose and mouth during the evacuation, so as to play a role of cooling and filtering.
