You can make fit testing easier and increase your confidence in the test results by using the PORTACOUNT Plus Respirator Fit Tester. Anyother way is the hard way!  \nThe PORTACOUNT Plus is the easy,  \nhassle-free way to reliably fit test a variety of respirator types. The PORTACOUNT not only eliminates  \nthe guesswork found with other testing methods, it also reduces the  \namount of work associated with fit  \ntesting in general. Plus, with the convenient FitPlus™ software that comes with each instrument, you can streamline the fit testing process even further by letting your computer do the work.  \nThe PORTACOUNT makes a direct measurement of respirator fit factors. There are no error-inducing assumptions made to calculate “equivalent” fit factors. The measurement is made while the person simultaneously performs dynamic moving and/or breathing exercises designed to stress the respirator seal  \nin ways that simulate anticipated workplace motions.  \nEliminate the guesswork  \nThe PORTACOUNT eliminates the human variables associated with qualitative methods. Variations in sensitivity to the challenge chemical or lack of cooperation can’t influence the test results because the employee makes no decisions. And, unlike other methods, the PORTACOUNT results are immediate and unambiguous. The PORTACOUNT Plus performs the fit test and delivers a “pass” or “fail.” It’s that easy.  \nThe PORTACOUNT won’t let you measure respirator fit incorrectly because the entire process is automated. Once the fittest is started, the PORTACOUNT goes through a programmed sequence. There is no opportunity to take shortcuts or skip critical steps. Compare that to qualitative methods like saccharin, Bitrex®, banana oil, and irritant smoke that involve tedious manual procedures. These procedures are often done incorrectly, thereby invalidating the fit test.  \nOSHA accepted  \nThe PORTACOUNT has been accepted by OSHA for compliance with all fit testing regulations since 1988. Recent standards, including the new OSHA respiratory protection standard 29CFR1910.134, specifically recognize the PORTACOUNT and provide specific protocols.  \nFit test any tight-fitting respirator  \nThe PORTACOUNT can be used to fit test almost any tight-fitting respirator including elastomeric half-and full-face masks, PAPRs, SCBA, and even disposable (filtering-facepiece) respirators.  \nPositive-pressure masks must be temporarily converted to negative-pressure mode per regulatory requirements prior to fit testing. Series-95 disposable masks require use of the N95-Companion™ accessory.  \nFit test in the employee’s own mask  \nYou can fit test with conventional probed test masks or use a fit test adapter to test people in their own respirator. Fit test adapters allow you to eliminate hygienic concerns associated with sharing a test mask and also facilitate simultaneous integrity testing of the respirator itself. Fittest adapters are available for most popular respirators. They can be obtained through TSI or directly from your respirator manufacturer.  \nEasy to use  \nThe PORTACOUNT Plus eliminates the awkward fit test hoods and chemical exposure concerns associated with other fit test methods. It uses the microscopic particles that exist in ambient air to measure the fit factor directly. The PORTACOUNT measures the concentration of these particles around the person’s head and then measures the concentration of those particles that leak into the respirator. The ratio of these two numbers is the fit factor. A fit factor of 100, for example, means that the air inside the respirator is 100 times cleaner than the air outside. The PORTACOUNT measures a fit factor for each of the fit test exercises and then computes an overall fit factor for the entire test, along with a pass or fail indication.  \nUnlimited fit te","cbCaivpO19ux4TE9","https://ap.wps.com/l/cbCaivpO19ux4TE9","pdf",943350,"English","# Key Benefits\n## Automated, Direct Fit Factor Measurement\n## Eliminate Guesswork and Human Variables\n# Compliance and Compatibility\n## OSHA-accepted Fit Testing\n## Fit Testing for Multiple Respirator Types\n## N95 Disposable Testing with N95-Companion\n# Fit Testing Workflow\n## FitPlus™ Software for Streamlined Process\n## Use with Own Mask and Adapters\n## Unlimited Fit Testing for Full-Face Masks","[{\"question\":\"How does the PORTACOUNT Plus measure respirator fit factors?\",\"answer\":\"It directly measures fit factors by using microscopic ambient air particles and calculating the ratio of particle concentration around the head versus inside the respirator during dynamic exercises.\"},{\"question\":\"What kind of results does the PORTACOUNT Plus provide?\",\"answer\":\"It performs the fit test and delivers an unambiguous “pass” or “fail” indication, with results available immediately.\"},{\"question\":\"Can the PORTACOUNT Plus be used for N95 disposable respirators?\",\"answer\":\"Yes.
