A brief analysis of the story of how gas masks were invented and their principles.
2022-02-17
Gas maskIt was inspired by the wild boar during World War I. The German army and the British and French allied forces fought over Belgium using chemical gas. At that time, more than 5,730 Cl₂ bottles were set up, releasing green smoke that drifted towards the allied positions with the wind, totaling about 180 tons of Cl₂, resulting in 50,000 soldier deaths and large areas of wildlife around, but miraculously, the wild boars in this area survived.
Therefore, scientists found that the nose of a wild boar is 50 times more sensitive than that of a dog. If there are irritating odors, they soften the soil through rooting, adsorbing some gases, and developed based on the shape of the pig's mouth.Gas maskThe first oneGas maskwas invented by Russian chemist Jeklinsky in 1912.
Gas maskThe principle
ModernGas maskis mainly divided into filtering and isolating types. The filtering type mainly relies on the anti-toxic carbon in the elements, which has a looser structure than activated carbon and can adsorb more toxic gases. Some also have a layer of filter paper or toxic enzyme. The isolating type mainly provides oxygen, mostly used underwater, in hypoxic high altitudes, or in sealed chambers.
Gas maskis an innovative direct protection device that can effectively protect a person's respiratory system, eyes, and facial skin during chemical, biological, radioactive contamination, or other severe pollution. It can also be used in various fields such as military, civil defense, industry, agriculture, warehouses, and scientific research. The mask is soft and suitable, with good elasticity in the straps, adjustable to ensure comfortable and sealed wearing. The large triangular lens is made of optical plastic, with a special surface treatment, providing a wide field of view, excellent optics, and impact resistance.
So,Gas maskhow to wear it?Gas maskIntroduction to the usage of
WearGas maskto reduce the damage of polluted air to the respiratory system and lungs. For personal safety, workers in environments with low concentrations of harmful gases and dust should wear gas masks to ensure life safety.
Because filtering typeGas maskis the most common on the market, here is a brief introduction to the usage of the filtering type.
First, before wearing, confirm whether the appearance and performance ofGas maskare good. For example, the appearance should not be cracked, deformed, the headband should have normal elasticity, the filter box and cloth should be clean and within the shelf life, and not contaminated.
When wearing, the first step is to cover the mask over the mouth corners, fix it on the face, and pull the head strap to the neck. The second step is to pull the lower strap to the back of the neck and hold it. The third step is to carefully check the connection points and the exhalation and inhalation valves to ensure no air flows between the face and the mask.
The above method is for reference only, as the materials and structures of different brands and modelsGas maskhave some differences. Therefore, for first-time users or those without experience, it is important to read the manual or consult customer service representatives. After all, life safety is more important than anything!
