Page 87: Appendix B Theory Of Operation
Appendix B Theory of Operation How the PortaCount Pro Respirator Fit Tester Works ® The PortaCount Pro fit tester measures respirator fit by comparing the concentration of microscopic particles outside the respirator to the concentration of particles that have leaked into the respirator. The ratio of these two concentrations is called a fit factor. -
Page 88: How The Portacount Pro Fit Tester Counts Particles
How the PortaCount Pro Fit Tester Counts Particles The PortaCount Pro fit tester is based on a miniature, continuous-flow Condensation Nucleus Counter (CNC), also known as a Condensation Particle Counter (CPC). A CNC takes particles that are too small to be easily detected, grows them to a larger, easily detectable size, and then counts them. - Page 89 The PortaCount Pro sensor consists of a saturator, condenser, and optical elements. The saturator is lined with an alcohol-soaked wick. A thermoelectric device is mounted between the saturator and condenser which cools the condenser and heats the saturator. After passing through the saturator, the aerosol (now saturated with alcohol vapor) enters the condenser tube.
- Page 90 (This page intentionally left blank) Appendix B...
-
Page 91: Appendix C Calculating Fit Factor
Appendix C Calculating Fit Factor Fit factor is defined as the particle concentration outside the respirator divided by the particle concentration inside the respirator. ® Because ambient concentration can vary over time, the PortaCount Pro Respirator Fit Tester calculates the fit factor by taking the average of the ambient concentrations measured before and after the respirator sample and then dividing by the concentration measured in the respirator. - Page 92 The following equation is used to calculate the overall fit factor in the PortaCount Pro fit tester: Overall where: FF = fit factor for test cycle number of test cycles (exercises). Disclaimer: The measurement provided by the PortaCount Pro Respirator Fit Tester is an assessment of respirator fit during a fit test only.
-
Page 93: Appendix D Calculating Particle Concentration
Appendix D Calculating Particle Concentration Particle concentration is calculated by counting the number of particles passing through the sensor in a given period of time. Since the flow rate is known (5.83 cm /sec), the particle concentration can be determined. In 1-Second Count Mode the equation is: ... - Page 94 (This page intentionally left blank) Appendix D...

Page 95: Appendix E Timing In Fit Test Mode
Appendix E Timing in Fit Test Mode Test Sequence ® When performing a fit test, PortaCount Pro Respirator Fit Tester automatically samples both the ambient air and the particles inside the respirator. An internal switching valve automatically switches between the two sampling ports. In each test cycle, (exercise) both an ambient sample and a respirator sample are taken. - Page 96 (This page intentionally left blank) Appendix E...

Page 97: Appendix F Using The Portacount Pro Respirator Fit Tester To Fit Test Positive Pressure Respirators
Appendix F ® Using the PortaCount Pro Respirator Fit Tester to Fit Test Positive Pressure Respirators On January 8, 1998, OSHA released the long-awaited revision to the Respiratory Protection Standard 29CFR1910.134. It replaces the standard with the same name and number that was released in 1971. This new revision has far reaching impact on a large number of existing OSHA standards in that it replaces certain provisions related to respirator use. - Page 98 Loose fitting respirators usually employ a hood that fits over a person's head and loosely seals around the neck. The quality of the seal is not dependent on a close physical match with the wearer's body. Since there is no "seal" to test, there is no requirement to do a fit test.
- Page 99 significantly lower than actual. Most PAPRs have a blower motor on the clean side of the filter. Most of these motors generate small particles that the PortaCount fit tester can easily measure. Likewise, air from SCBA tanks, and from compressors, contains significant numbers of particles.
