A respirator is a device designed to protect the wearer from inhaling hazardous atmospheres including lead fumes, vapors, gases and particulate matter such as dusts and airborne pathogens such as viruses.
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 ...

PAPRs can provide an assigned protection factor between 25 and 1000 depending on the type, as compared to an N95 mask's assigned protection factor of 10. [ 2 ] [ 3 ] When comparing various makes and models of PAPR, the supporting documentation from each of the respective manufacturers should be consulted in order to confirm the APF value of ...
Face shields provide additional protection and are worn over the standard eyewear; they also provide protection from impact, chemical, and blood-borne hazards. [ 14 ] Full-facepiece respirators are considered the best form of eye protection when respiratory protection is needed as well, but may be less effective against potential impact hazards ...
It effectively stops powdered chemicals. This mask can also serve as protection against respiratory viruses such as avian influenza or severe acute respiratory syndrome associated with the coronavirus (SARS), as well as against the bacteria of pneumonic plague and tuberculosis. [10] It is similar to the US-standard N95 respirator. [6]
They are not intended to provide protection from most airborne hazards. [ 2 ] [ 3 ] The European FFP1 mask , the lowest-grade standard available in the jurisdiction, is an example of a dust mask, being only certified to remove ~80% of dusts and mists.
