Respirators are worn by millions of U.S. workers.  They are classified as either air filtering or air supplying.  Examples of air filtering respirators include:  N95 (disposable), half-face, full-face, and powered air-purifying (PAPR).  These types of respirators are used to remove particles and/or gases and vapors from breathable air.  PAPRs are unique in that loose-fitting ones do not require fit-testing before use.  All other respirators require fit-testing to ensure that a proper seal exists between the respirator and face.  Supplied air respirators include SCBA and airline respirators.  These also require annual fit-testing to wear safely.

A surgical mask is not a respirator.  It does not form a seal against the face, and therefore does not offer protection from inhaled particles/vapors/gases.  A surgical mask is used to prevent infectious diseases that are transmitted through respiratory droplets.
