Quantitative respirator fit testing allows users to eliminate the guesswork and subjectivity associated with qualitative testing methods (Saccharin and Bitrex). Quantitative instruments such as the PortaCount Fit Tester provide users with objective and numeric data that accurately describes respirator fit.
Studies also show that quantitative fit testing achieves higher Simulated Workplace Protection Factors (SWPF) than qualitative methods for N95 filtering facepieces.* Not only does quantitative testing make people safer but fit test administrators no longer have to rely on a person’s senses and self-reported feedback to determine if a mask fits.
The PortaCount® Respirator Fit Tester Model 8048 is the only quantitative instrument that works for any type or brand of N95 filtering facepiece. Simplify your fit test program with one consistent, objective and automated testing experience across any respirator.
FitCheck® Mode gives users and staff the ability to see in real-time how respirator fit changes throughout donning and adjustment. This allows users to quickly evaluate respirator fit and efficiently match masks to even the hardest-to-fit staff. Real-time measurements also improve training by showing staff how to achieve the best fit with their mask, reducing failed fit tests and increasing staff safety.
Animated fit test steps guide staff through the proper movements for each test exercise, better identifying respirators that fit poorly. Animations free fit test administrators from the need to coach staff through the fit test, ensuring consistency and allowing time to multitask for increased productivity.
OSHA's New Modified CNC Protocols
The respirator fit testing process is now faster and more streamlined. The modified CNC protocols enable fewer, shorter fit test exercises. Instead of eight exercises, the new rules require four. Total fit test time is reduced from 7:15 minutes to 2:29.
