2. Post Certification  Steps that continue after respirator is granted NIOSH Approval.  Ensure that respirator continues to be produced according to NIOSH criteria.  Post Certification activities include:  Product Audits  Site Audits  Certified Product Investigation Process (CPIP)  Long Term Field Evaluation (LTFE)  Fire Fighter Fatality/Injury SCPA Evaluation Program (FFFIP)

3. Product Audits  Purchase units commercially to test and ensure performance to applicable criteria.  Typically filtering facepiece units.  Verify performance of all units through default to test program.  Shelf life testing:  Verify performance up through expiration date.

4. Product Audit Testing  Tests conducted on filtering facepiece respirators:  Respirator Performance  Filter efficiency and leakage (for valve)  Quality assurance evaluation  Check labeling, user instructions, visual inspection  NIOSH submits report to Approval Holder  Pass or Fail

5. Product Audit Outcome  If unit passes testing  No action required by Approval Holder.  Approval Holder can continue to manufacture and control quality of product to NIOSH approval criteria.  If unit fails testing  Certified Product Investigation Process (CPIP) is initiated and NIOSH sends letter to open investigation.  Approval Holder must identify cause of failure and provide resolution.

6. Site Audits  WHERE:  All manufacturing site locations, including approval holder subcontractors.  WHEN:  Typically every 2 years (every year in some cases).  WHO:  NIOSH or Contract representative.  HOW:  Evaluate against Title 42, Code of Federal Regulations, Part 84 (42 CFR 84) & NIOSH Approved Quality Control Plan at facility.

7. Site Audit Report Outcome  Following the Site Audit, NIOSH sends a report documenting to the Approval Holder.  Overall result of Site Audit:  Acceptable – No corrective actions required.  Provisionally Acceptable – Production of respirators may continue while the required corrective actions are implemented.  Not Acceptable – Failure to promptly complete corrective actions may result in Stop Sale and/or Revocation of NIOSH approvals.

8. Site Audit Process – Follow-up  Approval Holder provides NIOSH with documentation to show corrective actions have been completed.  At next site audit visit, NIOSH will verify that corrective actions were put into place.

9. Certified Product Investigation Program (CPIP)  PURPOSE:  To ensure the quality of NIOSH approved respiratory units by promptly investigating and resolving reports of product nonconformance issues.

10. Examples of Nonconformance Issues  Performance failure  Failure to maintain quality control requirements  Misleading advertising  Manufacturing under a private label without prior approval from NIOSH

11. When is a CPIP Needed?  When an approved NIOSH respirator is in nonconformance with the specified requirements in Title 42, Code of Federal Regulations, Part 84 (42 CFR 84).

12. CPIP Goals  Maintain quality of NIOSH approved units.  Investigate Internal, External and Self- Reported issues.  Document findings of the approval holder’s investigation and their corrective actions.  Address inventory units, field units and future production.

13. Possible Follow-Up Actions  User Notices  Stop Sales  Recalls  NIOSH Applications to make changes to:  QA Manual  Production Process  Engineering Design  Request to voluntarily rescind Approval Numbers

14. CPIP Closing  Has approval holder properly identified the cause of the nonconformance?  Has approval holder developed effective corrective actions to resolve nonconformance?  Has approval holder successfully addressed inventory units, field units and future production?  When NIOSH determines investigation can be closed, Approval Holder receives closing letter.

15. Long Term Field Evaluations (LTFE)  Purpose:  To evaluate long term field performance of self-contained self-rescuers (SCSR) units certified by NIOSH.  Method  Randomly selected units are collected from mines and are tested on the Automated Breathing and Metabolic Simulator.

16. LTFE  Outcomes:  Comparisons are made between deployed units and new units.  If a nonconformance to 42 CFR Part 84 is identified, a CPIP is opened.  Results of the LTFE testing are reported to mine operators, MSHA, and Manufacturers.

17. Fire Fighter Fatality/Injury SCBA Evaluation Program Overview (FFFIP)  Purpose:  To determine the conformance of SCBA involved in fire fighter injuries or fatalities to the NIOSH approval requirements found in Title 42, Code of Federal Regulations, Part 84  Inspection  Testing  To provide information resulting in the reduction of firefighter injuries and fatalities

18. FFFIP  History:  Evaluations have been conducted as part of respirator certification program since 1972  Congress included language in FY1998 budget directing NIOSH to investigate firefighter fatalities  Average of 7 SCBA investigations annually since FY1998

21. FFFIP: Inspection  Condition of major components  Approved configuration  Identifying information  Suitability for testing

22. FFFIP: Air Sampling and Testing  Air Sampling  Sample taken if air remaining in cylinder  Tested against CGA G-7.1  Dewpoint: OSHA 29 CFR 1910.134(i)(4)(iii) requires ≤ -50°F, NFPA 1500 standard requires ≤ -65°F  Testing  7 tests are performed if SCBA unit is suitable.  6 NIOSH, 1 NFPA  May replace cylinder and/or facepiece for testing depending on damage.

23. NIOSH Tests Performed  Rated Service Time Test/ Positive Pressure Test  How long can SCBA provide air?  Does SCBA maintain positive pressure in facepiece?  Gas Flow Test  Continuous airflow provided by SCBA while still keeping positive facepiece pressure.  Requirement is 200 lpm at full rated pressure and at 500 psig.

24. NIOSH Tests Performed  Remaining Service Life Indicator Test (Low-Air Alarm)  RSLI provides user with warning of air exhaustion  Must alarm at 20-25% or 23-27% of service life (pressure)  Six runs performed, average determines pass or fail

25. NIOSH Test Performed  Static Pressure Test / Exhalation Resistance Test  Static pressure is facepiece pressure at zero flow condition (≤ 1.5”H 2 O)  Exhalation resistance is facepiece pressure at 85 lpm continuous flow (≤ 2”H 2 O above static)

26. NFPA Air Flow Performance Test  NFPA 1981 breathing machine  Test parameters 103 lpm, 30 breaths/minute  Facepiece Pressure must remain between 0 and 3.5”H 2 O

27. FFFIP: Outputs  Report of inspection and testing results  Report provided to entity that submitted unit and SCBA manufacturer  Results provided to NIOSH - DSR or DSHEFS (if involved)  Field problem investigation initiated if warranted

28. FFFIP: Key Findings  Few evaluations result in a Field Problem Investigation  < 5%, based on sample from last five years  Maintenance, maintenance, maintenance  Most common test failure is remaining service life indicator (usually set high)
