Respiratory protective devices. Selection, use and maintenance. Fit-testing procedures | Status: Current, Under review

1 Scope 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’s face and the respiratory interface (RI). A complete RPD programme is defined in ISO/TS 16975‑1. This document specifies requirements for conducting RPD fit testing and includes

• — qualifications/competences of fit-test operators,
• — specific fit-testing procedures,
• — interpretation of fit-test results, and
• — record keeping.

A fit test is not required for escape-only RPD.
