How to apply for NIOSH Respirator Approval

As announced at the November 16, 2016 meeting for all manufacturers, Conformity Verification and Standards Development Branch is releasing SAF V9 for optional use. When using SAF V9, you will no longer need to have Java installed on your PC to fill out applications. While SAF V9 will require some additional information in applications for new approvals, we believe the overall process will be improved offering benefits in greater accuracy and quicker processing in some circumstances. SAF V8 is still the official version of the application software, but if you wish to try SAF V9, please contact the Records Room and let us know you would like to try a copy of SAF V9. We are soliciting comments on all aspects of its operation, so we encourage you to share your observations with us.

Standards for Respirators with Chemical, Biological, Radiological, and Nuclear Protection

Standards for Respirators without Chemical, Biological, Radiological, and Nuclear Protection

Standards Under Development

  • Powered Air-Purifying Respirators
    A comprehensive standard for certifying Powered Air-Purifying Respirators (PAPRs) is under development. Information submitted to the dockets 008, 008A, and 010 will be considered in the context of development of conceptual standards for PAPRs, as well as updating equipment performance requirements to improve respirator user safety and health.

Lists of approval projects that are currently being processed, indicating the dates that processing steps were begun and completed.

Only projects that succeeded in granting approvals are included among these averages. The times shown in the table represent the average number of days the projects spent in processing. Individual projects may have resulted in the issuance of multiple approvals. Unless otherwise noted, the times listed exclude the longest 10 percent of projects in each category.
