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.
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.
