Military Gas Mask Filter
The Low Down On Particulate Respirators
Though an innocuous sight from hospitals to construction zones, particulate respirators are a prime example of technology honed by warfare and military applications, used for every day practical uses by civilians. Particulate respirators are straightforward face masks worn over the mouth and nose which use mechanical means to filter particulates – miniscule pieces of matter or debris caught in the air, for example saw dust, but also biological air-borne pollutants – out of the air before it is consumed.
Yet another form of protective equipment to, of course, satisfy your requires. In sterile environments like a hospital operating room, the alternative is intended: masks are worn to prevent liquid and aerosol dust from the wearer’s mouth from spreading infectious bacteria. In places like Japan, it isn’t even uncommon for regular people to wear the mask while sick in order to prevent spreading the cold. Wool is a commonly used material, as well as plastic, glass, or cellulose, though normally some combination of these materials is used. Particulate respirators are created to be disposable so the materials used are typically abundant and of very low cost.
Particulate respirators can trace their heritage as far back as World War One, when chemical warfare ended up being employed for the first time on a large scale. At the Second Battle of the Ypres, Germany became the first country to employ chemical weapons in this fashion, dumping 168 tons of chlorine gas the allied front lines, killing thousands in just minutes.
The British and French would eventually retaliate with gas attacks of their own, ending up in such appalling casualties on both sides that chemical warfare was subsequently prohibited by the Geneva Convention and is still illegal under the rules of international warfare to this day. Canadian troops were the first to devise a primitive defense against chlorine gas, discovering that urine soaked rags averted them from inhaling the gas.
The ammonia from the urine worked to counteract the chlorine, protecting their lungs from the searing consequences of the gas. This wasn’t the first time respirators had been designed. Leonardo Da Vinci even created a respiratory device to protect against another chemical weapon of his own invention. Other inventers and scientists had developed respiratory gadgets for usages in mining operations, but none were so simple as a piece of cloth treated to keep pollutants at bay.
The use of chemically treated materials for protective face masks was fantastic for applications in construction or repair, where workers are quite often confronted by dangerous gaseous substances.
Similarly, another common technique of air filtering was also designed in the course of wartime for military application. HEPA filters, a common fixture in almost any house hold air filter, were first developed as part of the Manhattan Project during World War Two. Because HEPA filters can filter 99.97% of all airborne particles .3 micrometers in diameter or larger, their use as a respirator to protect Manhattan Project researchers from inhaling harmful radioactive particles was highly effective. Today, HEPA filters are used for everything from air purifiers to vacuum cleaners.
