This document specifies guidance on how to conduct fit testing of tight-fitting respiratory protective device (RPD) and on appropriate methods to be used. Fit testing is only one element of a complete RPD programme. The intention of fit testing is to evaluate the effectiveness of the seal between the wearer\u2019s face and the respiratory interface (RI). A complete RPD programme is defined in ISO\/TS 16975\u20111 .<\/p>\n
This document specifies requirements for conducting RPD fit testing and includes<\/p>\n
qualifications\/competences of fit-test operators,<\/p>\n<\/li>\n
specific fit-testing procedures,<\/p>\n<\/li>\n
interpretation of fit-test results, and<\/p>\n<\/li>\n
record keeping.<\/p>\n<\/li>\n<\/ul>\n
A fit test is not required for escape-only RPD.<\/p>\n
