A respirator is a means of protection against the ingress of dust, smoke or harmful gases into the respiratory system. At the moment, one of the most reliable means of protection.
First respirators
The first invention and use of a respirator was mentioned in 1799 by Alexander Humboldt - he worked as a mining engineer. The first official patent was registered in the USA in 1848. At first, respirators used workers to do dusty work, but later the World War broke out - then the German army first used chemical weapons on the resistance line. Since the soldiers were unprepared for this, more than 6,000 people died from suffocation in a matter of minutes, and those who survived were blinded. Heavy gas settled on the ground, and soldiers had to leave the trenches. Canadians were among the first to realize that it was necessary to use masks, and a bit later they began to use gas masks. At the moment, one of the best protective equipment at an affordable price is a 3M 8112 respirator. 8112 masks were created by 3M and are now considered one of the leaders in the Russian market.
Details on a respirator 3M 8112
The manufacture of 8100 series respirators began in Russia in 2008, and during this time many Russian companies have adopted protective masks from 3M. The device has a convenient cup-shaped shape, making it easy to put on and take off. A high-quality filter also has minimal resistance to breathing. The 3M 8112 respirator is lightweight and resistant to deformations, a long nose clip securely fixes it on the face, avoiding depressurization. Masks are made of gypsum, they allow you to work in different temperature conditions: from -30 to +70 degrees.
Anti-aerosol respirator 3M 8112
The 3M anti-aerosol respirator is designed as a half mask. It serves to limit the ingress of gases into the respiratory tract. Typically, such protective masks are used in engineering, chemical industry and petrochemistry, oil and gas industry, utilities, mining. 3M respirators fit snugly and perfectly perform their functions. The device is equipped with elastic bands for attaching the headband at four points, allowing to maintain tightness.
Using a protective mask, you should understand that the result of its work will directly depend on how it fits to your head. After you put on the mask, there should be no gaps through which harmful fumes can get. After a certain operating time, it is necessary to change the filter.
