This research project was initiated to assess the risk associated using the US Navy SCBA composite cylinders (DOT FRP-1 and CFFC) beyond their 15 year service life to a maximum of 30 year of service from the original manufacturing date of the cylinder. This research project was developed by PHMSA, Hazardous Materials Engineering and Research Division and requested the US Navy to implement the project. The US Navy and their technical team and contractor has competed the project.

Mechanical (performance), nondestructive testing (NDT) data and conclusion of this research project have been used as part of technical information for evaluating Navy's application for special permit (SP 15720). For technical question, contact Mr. Mark Toughiry, 202-366-4545.
