The goals are to strengthen scientific basis on which NIOSH policies and recommendations for respiratory protection depend, and to develop a validated, complete respirator performance test for high APF respirators to be incorporated into the NIOSH certification program. The specific aims of this project are: (1) compare fit factors from six quantitative fit test methods to Freon exposure dose; and (2) validate performance tests as a condition of certification.
