Gas masks were inspired by wild boar.
through research and experiments, scientists found that wild boar especially likes to use its powerful long mouth to arch the soil to find the roots of plants and some small animals in the field. When they smell a strong irritating smell, they often arch to avoid it. When the Germans attacked the allied forces with poison gas, the clever wild boar put his nose and mouth into the soil and escaped the disaster. After further scientific analysis, it is concluded that the soft soil particles adsorb and filter the poisonous gas because the wild boar arches the ground with its mouth, so that they are spared.
The scientists of the two countries got inspiration from it. According to the principle that soil can filter poison, they selected charcoal which can not only adsorb toxic substances, but also make the air smooth, and soon designed and manufactured the first batch of gas masks in the world that imitated the shape of wild boar's mouth.
Extended information:
As personal protective equipment, gas masks are used to provide effective protection for people's respiratory organs, eyes and facial skin. The mask consists of a mask, an airway and a canister. The mask can be directly connected with the canister or canister, which is called direct connection. Or use the airway to connect with the canister and the canister, which is called catheter type.
according to the protection requirements, various types of canisters can be selected for gas masks, which are used in chemical industry, warehouses, scientific research and various toxic and harmful working environments. The gas mask is mainly composed of filter element, mask body, eye window, expiratory communication device and headband, which have their own responsibilities and can cooperate tacitly at the same time.
People working in toxic and harmful gas environment are using gas masks as protection; However, the structure of general civilian gas masks is not as complicated as that of military, and the indexes are not as strict as that of military. For civil chemical protection, more appearances are designed to meet the needs of different people.
