Performance Evaluation of the Puritan-Bennett Crew-Member Portable Protective Breathing Device as Prescribed by Portions of FAA (Federal Aviation Administration) Action Notice A-8150.2

摘要

This study was undertaken, on request, to evaluate the performance of the Puritan-Bennett portable crew protective breathing device for contaminant leaks. O2, CO2 levels, inhalation/exhalation pressure, and inhalation temperature tests were conducted in the facilities of the FAA Civil Aeromedical Institute (CAMI) in Oklahoma City, OK. (test chamber and altitude chamber). The duration and workload profile are described in FAA Action Notice A-8150.2. The test sequence followed an iterative process in which problems were identified, modifications made to correct deficiencies, and the device retested until problems could be solved. With adequate quality assurance, the final version of the Puritan-Bennett crewmember portable protective breathing device, as tested at CAMI, would meet the requirements of FAA's Action Notice A-8150.2 regarding contaminant leak protection, O2 concentration, CO2 concentration, inhalation/exhalation pressures and inhalation temperature.
