Question 131: 10 CFR 20.1703 (a) (3) (iii) requires that
respirators be tested for operability immediately prior to
each use. How is this to be done?
Answer: This requirement is not new. It is essentially
the same as the requirement in 10 CFR 20.103 (c) (2). For
guidance on respirator operability tests (fit checks), see:
(1) Regulatory Position C.4.C in Regulatory Guide 8.15,
(2) Section 8.5.2.3 in NUREG-0041, and (3) Section 7.4 and
Appendix A7 in ANSI Z88.2-1980. (Reference: 10 CFR
20.1703).
