MPR Associates, Inc. — Department of Homeland Security SBIR Phase I: Currently, SCBA lenses are made from high-heat polycarbonate with a maximum service temper

Description

Currently, SCBA lenses are made from high-heat polycarbonate with a maximum service temperature rating of 275 deg F to 383 deg F. However, first responders may encounter temperatures due to fire reaching 1000 deg F to 1400 deg F at face level with a heat flux density of about 2.2 W/sq-cm. Developing a more durable, high-heat resistant lens will significantly improve firefighter safety and enable firefighters to function effectively in more severe environments than with current SCBAs. MPR Associates, Inc. will work with Scott Health and Safety to identify candidate test materials based on the material`s ability to provide increased durability, clarity, resistance to impacts, and improved heat resistance. A test plan and test procedures will be developed based on current and future (i.e., planned) industry accepted standards (e.g., NIOSH, NFPA, EN). Testing will emphasize the ability of test materials to withstand the extreme heat generated by compartmentalized fires. Commercialization of a high temperature face piece will take advantage of the economy of scale due to the potentially large government and commercial customer base, thus providing a viable improvement for DHS and other users of SCBAs. The improved face piece also could be back-fit to SCBAs currently in use.
