Abstract
Anthropometric variables for predicting the fit of half mask respirators were examined in 68 volunteers. Measurements included: biectoorbitale breadth, bizygomatic breadth, bigonal breadth, menton/nasion length, menton/subnasale length, subnasale/nasion length, biocular breadth, nasal root breadth, nose width, lip width, bitragion/menton arc, and bitragion/subnasale arc. The subjects were fit with a small, medium, or large size of a United States Safety Series 200 half mask respirator. Along with a manual fit check, a quantitative fit test was performed according to American Standards Institute method Z88.2-1980 which measured the amount of a fluorescent whitening agent that penetrated the respirator after exposure to the agent in a test chamber. Results showed that biocular breadth, menton/subnasale length, nasal root breadth, and nose width were significantly correlated with the degree of fit in most analyses. Menton/subnasale length was a significant predictor of fit in all analyses. The authors conclude that facial dimensions can be used to predict respirator fit factors for persons wearing the Safety Series 200 half mask respirator. The data suggest that facial dimensions other than those currently used may be more appropriate for half mask respirator fit factors.
