Respirator and surgical mask efficacy from cough aerosols

Objective

  • Determine efficacy of FFR and surgical masks when exposed to aerosols generated by a cough simulator
Cough Generation testing device diagram

Applicable Standards

  • Polices and procedures

Key Partners

  • HELD - NPPTL Collaboration
  • NIOSH/CDC/DHHS
  • Other Federal Agencies (OSHA/EPA/FDA)

Stakeholders

  • Safety Professionals
  • Other Government Agencies
  • Other Research Organizations

Project Scope


  • Controlled studies are needed to address the efficacy of surgical masks and FFR use in preventing transmission of influenza and provide healthcare recommendations

Milestones

  • Part 1 (NPPTL lead) Measure filtration performance of surgical masks and FFR (FY2008-2009)
  • Part 2 (HELD lead) Close proximity simulation experiments (FY2009-FY2010)
  • Part 3 (HELD lead) Examination room simulation experiments (FY2010-FY2011)

Outputs

  • Establish greater understanding of surgical mask and FFR efficacy when exposed to cough aerosols
  • Research based recommendations for effective respiratory protection strategies in healthcare settings
  • Technology Transfer will primarily be through technical presentations and peer reviewed publications

Outcomes

  • Improved worker respiratory protection as a result of updated guidelines/recommendations for use of FFR and surgical masks
