| Abstract |
The basic respirator equation states that the contaminant level inside a respirator (Cl) is the product of the contaminant level outside the respirator (Co) and the decimal fraction penetration (P). A probability model based on this relation accounts for between-wearer and within-wearer variability in both Co levels and P values. The assumptions underlying the model are consistent with current knowledge about the variability in Co levels and P values. The model provides the basis for assessing the probability of over-exposure to acute toxicants and to chronic toxicants among a respirator-wearing population. |
