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.
A powered air-purifying respirator (PAPR) is a type of respirator used to safeguard workers against contaminated air. PAPRs consist of a headgear-and-fan assembly that takes ambient air contaminated with one or more type of pollutant or pathogen , actively removes (filters) a sufficient proportion of these hazards, and then delivers the clean ...
The respiratory protective devices (RPD) can protect workers only if their protective properties are adequate to the conditions in the workplace.Therefore, specialists have developed criteria for the selection of proper, adequate respirators, including the Assigned Protection Factors (APF) - the decrease of the concentration of harmful substances in the inhaled air, which (is expected) to be ...
Respirator assigned protection factors were also to be updated, along with chemical cartridge requirements. [ 20 ] [ 21 ] On July 10, 1995, in response to respirators exhibiting "low initial efficiency levels", new 42 CFR 84 standards, including the N95 standard, were enforced under a three-year transition period, [ 22 ] ending on July 10, 1998 ...
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 ...
Respirators range from cheaper, single-use, disposable masks to reusable models with replaceable cartridges. There are two main categories: the air-purifying respirator, which forces contaminated air through a filtering element, and the air-supplied respirator, in which an alternate supply of fresh air is delivered. Within each category ...

Elastomeric respirators are examples of air-filtering respirators, in contrast to air-supplying respirators. Air-supplying respirators are usually positive-pressure, so they leak outwards, and thus offer better protection. They are more complex and heavier, but less bulky about the head, and can be worn for longer. [1]
