Frequency of Fit Testing - FY06

NOTE: This page is archived for historical purposes and is no longer being maintained or updated.
Current Information can be found at: Frequency of Fit Testing - FY07

Objective

  • The goals of this project are to quantify the benefit of annual fit testing and assess causative factors affecting the temporal changes in respirator fit. Specific aims are to: (1) determine the percentage of fit test failure resulting in a new model and/or size; (2) identify differences between filtering facepieces and elastomeric respirators; and (3) investigate the effect of weight change, face change, and other factors on temporal changes in respirator fit.

Applicable Standards

  • 29 CFR 1910.134
  • ISO TC94 SC 15

Key Partners

  • OSHA, California-OSHA, ISEA
  • Lawrence Livermore National Laboratory
  • Society for Healthcare Epidemiology in America (SHEA)

Stakeholders

  • OSHA
  • MSHA
  • ANSI
  • AIHA
  • ISO
  • Respirator Users

Project Scope

  • A field study will be conducted to gather annual fit testing records to determine the percentage of fit test failure resulting in a new model and/or size. Differences between filtering facepieces and elastomeric respirators will be investigated.
  • A laboratory study will be conducted to assess causative factors affecting temporal changes in respirator fit. The possible causative factors include: weight gain or loss, face size change, 3-D scans and nose shape change, wrinkling and scarring, medical procedures, BMI, percent body fat, height, age and gender.

Milestones

  • Develop a field study protocol
  • Develop a lab study protocol

Outputs

  • None for FY06

Outcomes

  • None for FY06
