Respirator Selection: Up to 5 milligram per cubic meter: Any air-purifying half-mask respirator with organic vapor cartridge(s) in combination with an N95, R95, or P95 filter. Pohanish, in Sittig's Handbook of Toxic and Hazardous Chemicals and Carcinogens (Seventh Edition), 2017 It will be apparent that, although respirators are the most convenient form of RPE and have many legitimate applications, they also have some serious drawbacks and the circumstances in which they are used should be carefully considered. The purifying element should be replaced after use or after the elapse of a certain time according to a specified policy. It is essential that respirators be kept in good condition and not held too long in stock otherwise, the air-purifying element and/or the facepiece may deteriorate.

Some toxic gases are irritant to the face and for these full face protection should be used. Respirators should not generally be used against gases which have a high odor threshold or no odor at all, since odor is the only warning of failure of the respirator. There are a number of toxic gases for which a respirator is quite unsuitable. The element is designed to protect against a particular chemical or group of chemicals and should not be used for other substances. Alternatively, it may act as a catalyst: carbon monoxide is oxidized catalytically to carbon dioxide. The purifying element may work in several ways. In the former case, they are commonly referred to as ‘gas masks.’ A respirator intended for one type of application should not be used for another. Respirators are produced for military, fire fighting, and industrial uses. A person breathing air with an oxygen concentration of less than about 16% may manage to do light work for a few minutes, but is likely to exhibit symptoms ranging from labored breathing to unconsciousness or death. The concentration of oxygen in normal air is approximately 21%. It will not sustain breathing in an asphyxiating atmosphere. The filters available for respirators are of three types: (1) filters for particular gases and vapors only, (2) filters for dusts and other particulate materials, and (3) combination filters for particular gases and vapors and for dusts and other particulates.Īs already stated, the air-purifying respirator differs fundamentally from the air-supplied RPE in that it is not itself a source of air and is therefore of little use unless breathable air can be drawn through it from the surrounding atmosphere.

Thus, half-mask and full face mask respirators may be of the PI, P2, or P3 specification. A powered respirator has a fan to assist the flow of air through the filter.Įach type of respirator is available in three performance classifications. A full face mask respirator does cover the whole face the wartime ‘gas mask’ is of this type. The disposable facepiece or the half-mask respirator fits over the nose but does not cover the whole face. FIT MASK is a half-mask according to EN 140 filters 87 and 987 are manufactured according to EN 14387 and EN 143 standards.In Lees' Loss Prevention in the Process Industries (Fourth Edition), 2012 25.16.4 Air-Purifying Respirators
