![]() ![]() They also protect against higher concentrations of dangerous chemicals. These use their own air tank to supply clean air, so you don’t need to worry about filters. Self-Contained Breathing Apparatus (SCBA) is the respirator commonly used by firefighters. When the user inhales, air is pulled through the filter. The cartridge may have a filter to remove particles (such as a biological weapon), charcoal (to remove certain chemicals), both, or other parts. This respirator includes a facepiece or mask, and a filter/cartridge (if the filter is in a metal shell it is called a “canister”). Even if you can’t see the particles, there may be too many in the air for this respirator to provide adequate protection.Ĭhemical Cartridge/Gas Mask respirator Gas masks are also known as “air-purifying respirators” because they filter or clean chemical gases and possibly particles out of the air as you breathe. Particulate respirators are “air-purifying respirators” because they clean particles out of the air as you breathe. The commonly known “N-95” filtering facepiece respirator is one type of particulate respirator, often used in hospital to protect against infectious agents. They do not protect against chemicals, gases, or vapors, and are intended only for low hazard levels. These respirators only protect against particles. Particulate respirator The particulate respirator is the simplest, least expensive, and least protective of the respirator types available. There are several different types of respirators, as described below.

Some escape respirators come in a package that must remain sealed until use, so you need to be trained using a special “practice” version. Sometimes you can practice using your own respirator. Every respirator contaminated with hazardous chemicals should be decontaminated and disposed of properly.Īll respirators require training to be properly used. Some respirators prevent the user from talking while others have speaking capabilities. Others use a nose clip and mouthpiece, which is clenched between your teeth, similar to a snorkel. Some respirators require testing to ensure a tight fit to the face, and should not be used with facial hair.
