Respiratory protective equipment (RPE), also called protective breathing equipment (PBE) in the US, [1] is a form of personal protective equipment designed to protect the wearer from a variety of airborne hazards in the form of a gas, fume, mist, dust or vapour. Respirators filter the air to remove harmful particles and alongside the breathing ...
Use of the TC-14G canister schedule or the TC-23C chemical cartridge schedule for a given respirator depends on whether "acid gas" is a designated contaminant, which is designated for gas mask canisters only, or if the manufacturer is obligated to list all designated contaminants supported by a given chemical cartridge.
Example of measurement of efficiency of the respirator (in the workplace). Description: (1) personal sampling pump, (2) the cassette and the filter for determining the concentration (in the breathing zone), (3) the sampling line (from the breathing zone), (4) the cassette and the filter to determine the concentration (under a mask), and (5) the sampling line (from the mask).
This full-face mask also protects the eyes, and has an inner orinasal mask to reduce dead space. Pink hard-case P100 particulate filter cartridges make their presence or absence conspicuous at a distance. Elastomeric respirators are examples of air-filtering respirators, in contrast to air-supplying respirators.
The advantages of this method – if harmful gases have warning properties at concentrations less than 1 PEL, the replacement will be produced on time (in most cases, at least); the application of this method does not require the use of special cartridges (more expensive) and accessories; replacement happens when one needs to do it – after ...
The European respirator standards refer to the filtering classification by EN 149, EN 14683, and EN 143, all European standards of testing and marking requirements for respirators. [1] FFP standard masks (where FFP stands for filtering facepiece) [2] cover the nose, mouth and chin and may have inhalation and/or exhalation valves. [1]

Filtering facepieces are typically simple, light, single-piece, half-face masks and employ the first three mechanical filter mechanisms in the list above to remove particulates from the air stream. The most common of these is the white, disposable standard N95 variety; another type is the Surgical N95 mask.
