Fit testing of tight-fitting respiratory protective facepieces has been in use for some years, but there are still widespread misconceptions and misunderstandings about what a fit test pass actually signifies. Various aspects frequently generate research papers, and there are three relevant ones in this issue (Han and Lee, 2005Go; Kuo et al., 2005Go; Vaughan and Rajan-Sithamparanadarajah, 2005Go). In this commentary we will try to place fit testing in context with respect to UK and international practice, and describe its relevance to achieving effective control of exposure by using respiratory protective devices (RPDs).


   FIT AND PROTECTION—WHAT IS THE DIFFERENCE?
 
To be sold within Europe, RPDs must be CE marked. This is usually achieved by complying with a harmonized European (CEN) standard. One of the tests that is applied to nearly all RPDs (except mouthpiece devices) is the measurement of total inward leakage (TIL), which comprises face seal leakage, filter penetration and exhalation valve . . .
