The test results are displayed as a numerical Fit Factor. The CBRN Mask Fit Tester does not require the use of aerosol test chambers or CS gas chambers to perform the mask fit evaluation. It can be used almost anywhere—at mask issue sites, training facilities, or even in the field.  \nThe fast, accurate fit testing with use of the CBRN Protection Assessment Test System helps verify that personnel are getting the ultimate protection from their masks. It also helps CBRN trainers to quickly identify and correct problems with the fit of a soldier’s mask. The numerical test results can be entered into the personnel files to serve as a permanent record of training. See why this system is already fully deployed by military organizations worldwide.  \nApplications  \n▪ Ability to fit test at mask issue sites, training facilities, or even in the field  \n▪ Fit testing of CBRN masks  \n▪ Design evaluation of CBRN masks  \nFeatures and Benefits  \n▪ Gives numerical indication of mask fit and mask integrity  \n▪ Verifies that personnel are getting the best possible protection from assigned mask  \n▪ Provides highly sensitive detection of mask leaks  \n▪ Real-Time Fit Check Mode helps training personnel to quickly identify and correct problems with mask fit  \n▪ Uses programmed exercises to simulate normal field activities  \n▪ Portable, easy-to-use unit operates almost anywhere  \n▪ Runs off AC mains power or battery pack (optional accessory)  \n▪ Includes effective self-test functions  \nHow Does It Compare With Earlier Mask Fit Test Methods?  \nWith other fit test methods, such as CS gas chambers, Bitrex®, saccharin, or irritant smoke tubes, the challenge agent concentration is uncontrolled and unmeasured. Sensitivity of the test subject to detect leakage during the test must be relied upon. For such reasons, there is tremendous variability in the PASS/FAIL evaluations using these other fit test methods. Because of this variability, most occupational health and safety regulations only allow their use when the required fit factor is less than 100. Modern CBRN masks are capable of fit factors of more than 10,000 . This leaves a testing gap of more than two orders of magnitude.  \nThe CBRN Mask Protection Assessment Test System can accurately measure fit factor ratios of 50,000 or even higher. This fit factor measurement is controlled automatically by the unit. It does not depend on the sensitivity of the test subject to CS gas, Bitrex, saccharin, or irritant smoke. The CBRN Mask Protection Assessment Test System uses microscopic particles which are naturally present in the surrounding air asthe challenge agent. The sensor inside the unit compares the particle concentration outside the mask with the concentration inside the mask and then calculates the fit factor. Since themask’s filter canister stops all particles, any particles which are detected inside the mask must have entered through a leak.  \nWhy Do You Need To FitTest?  \nModern CBRN masks are capable of a high degree of protection, but ONLY if they fit correctly and are donned properly. A mask that is capable of protection factors greater than 10,000 may only give a protection factor of 50 if it is incorrectly donned or isnot the optimum size. The CBRN Mask Protection Assessment Test System is extremely sensitive to mask leakage and can measure fit factors to 50,000 and higher. It is the quickest, easiest way to ensure your masks provide the maximum possible protection of personnel.  \n\n| CS Gas, Banana Oil Tests up to 100\u003Cbr>\u003Cbr>| Potential Protection From Your Existing Masks\u003Cbr>\u003Cbr>| Modern CBRN Masks Can Give FF >10,000\u003Cbr>\u003Cbr>|\n| --- | --- | --- |\n| \u003Cbr>Testing Gap |  |  |\n| \u003Cbr>0\u003Cbr>100 1,000 5,000 10,000 |  |  |\n\nHow ","cbCaioaKgkegDjev","https://ap.wps.com/l/cbCaioaKgkegDjev","pdf",606474,"English","# Applications\n## Fit testing and design evaluation\n# Features and Benefits\n## Numerical Fit Factor and leak detection\n# How Does It Compare With Earlier Mask Fit Test Methods?\n## Controlled challenge vs. uncontrolled methods\n# Why Do You Need To Fit Test?\n## Protection depends on correct fit\n# How Hard Is The System To Operate?\n## Start Test and real-time results\n# How the 8020M Works\n## Particle sampling and fit factor calculation","[{\"question\":\"What does the 8020M measure during a mask fit test?\",\"answer\":\"It measures the concentration ratio of naturally occurring microscopic dust particles outside versus inside the mask, then calculates a numerical Fit Factor that reflects fit and integrity.\"},{\"question\":\"How is the 8020M different from CS gas chambers or irritant-based methods?\",\"answer\":\"Earlier methods rely on uncontrolled and unmeasured challenge agent concentrations and the test subject’s ability to detect leaks, leading to variability in PASS/FAIL results.
