University of Arizona Filter Study (Fire Fighter Overhaul and Wildland Operations) - FY07

NOTE: This page is archived for historical purposes and is no longer being maintained or updated.

Objective

  • Test respirator breakthrough for multi-contaminant cartridges in burn center, where contaminants better represent overhaul exposures
multi-contaminant cartridges diagram

Applicable Standards

  • 29 CFR 1910.134
  • NFPA Respirator Standard (New)

Key Partners

  • None

Stakeholders

  • Fire Fighters performing overall and wildland operations
  • Respirator manufacturers

Project Scope


  • Validate filter cartridge laboratory test method
  • Test air-purifying respirator (APR) cartridges for different combinations of burning materials
  • Evaluate effectiveness of APR's in overhaul and wildland operations

Milestones

  • 4Q FY07
    • Identify ambient concentrations by burnt materials
    • Determine contaminant breakthrough of commercial canisters
    • Recommend changes to respirator cartridges for use by fire-fighters

Outputs

  • Data to support establishment of a respirator standard by NFPA
  • Report of breakthrough contaminants
  • Listing of contaminant measures (e.g., CO, respirable particulates) indicating respirator ineffectiveness

Outcomes

  • Availability of appropriate cartridges for overhaul operations
  • Reduced chemical breakthrough
  • Reduced exposure risk while wearing APR's during overhaul
