The Department of Defense DoD is one of the largest consumers of aqueous film-forming foam AFFF for suppressing liquid-fuel Class B fires. However, concentrated AFFF solutions are likely to create a variety of problems for system piping, to include corrosion. In turn, the corrosion damage can result in system failure or a type of false fire discharge of foaming agent. To demonstrate a pipe lining to arrest pitting corrosion and extend system life, a two-part epoxy pipe lining material was applied in situ to the AFFF fire-suppression system of an aircraft maintenance hangar at Fort Drum, NY. The AFFF system under test, however, was decommissioned and replaced at the end of the study due to the failure of auxiliary equipment not related to the coating process. Thus, it was not possible to calculate an actual return on investment ROI for the tested system the ROI for this project is zero. Because the system was decommissioned, researchers could not evaluate the projects key metric for success and so, the coating lining material could not be recommended at this time for DoD-wide implementation on AFFF distribution or fire-suppression sprinkler systems.
