Project Scope

  • Develop performance standards, Standard Test Procedures (STP), Standard Operating Procedure (SOP) and acquire state-of-the-art test equipment and test facilities to support NIOSH-certification of CC-SCBA


  • Evaluate present technology
  • Propose new standards
    • Include CBRN Protection (Optional)
    • Include Fire Resistant Protection (Optional)
    • Eliminate obsolete performance requirements/designs
    • Incorporate new test technology
    • Incorporate the latest findings on human physiology needs


  • Eliminate obsolete requirements
  • Update or add STP and SOP for testing current, new, CBRN, and Fire Resistant performance requirements
  • Allow for flexibility for greater variety of CC-SCBA designs to be certified
  • Certified CBRN CC-SCBA with optional high heat and flame resistance properties
  • Availability of CC-SCBA for use in CBRN and high radiant heat and flame (If NIOSH limitation on CC-SCBA use in heat is repealed) environments
  • Final rule stated in Title 42 CFR Part 84, Subpart Q


  • Improve CC-SCBA performance and safety for traditional users as the mine rescue teams and for potential new users such as the military, first responder and fire service communities
