29 CFR 1910.134 states that a written, formal Respiratory Protection Program (RPP) be established in any organization where respiratory protection is required. Although the requirements for training of personnel administering the fit tests are somewhat vague, the implication is that the Administrator of the RPP is responsible for the criteria for training the person who actually conducts the fit tests.

29 CFR 1910.134 describes in detail the requirements for who must be fit tested.

A Quantitative Fit Test can best be defined as one which does not depend on the ability of the test subject to detect a challenge agent, nor does it depend on the truthfulness of reporting the sensing of the challenge agents and is therefore completely objective. Further, a Quantitative Fit Test provides defensible metrics and automatically captures results into a secure database for future reference.
