Evaluation of irritant smoke qualitative fitting test for respirators
The results of a qualitative fit test, utilizing an irritant smoke, were compared to the results of a quantitative fit test, utilizing an oil mist aerosol, for both half-mask and full facepiece respirators. For a respirator wearer combination having a fit factor less than 10, as determined by the quantitative test, the point estimate of the probability of that combination's not being rejected by the irritant smoke qualitative test was found to be 0.00 with 95% confidence that this statistic will not exceed 0.08. For a respirator wearer combination having a fit factor less than 100, the point estimate of the probability of that combination's not being rejected by the qualitative test was found to be 0.04 with 95% confidence that this statistic will not exceed 0.08. The point estimate of the probability of rejecting a fit factor greater than or equal to 10 was found to be 0.58, with 95% confidence that this statistic will not exceed 0.65. The point estimate of the probability of rejecting a fit factor greater than or equal to 100 was found to be 0.30, with 95% confidence that this statistic will not exceed 0.39.
