CLASSIFICATION OF RESPIRATORY PROTECTIVE DEVICES, THEIR LIMITATIONS, AND PRECAUTIONS IN THEIR USE
Respiratory protective devices fall into two broad groupings on the basis of their mode of functioning : atmosphere-supplying respirators ; and air-purifying respirators.
A more detailed classification, along with a brief description and the limitations of the various types of respirators follows :
