Lessons Learned - Firex Deluge Valve Configurations
Year: 1991
Abstract: Description of Driving Event:
The remote manual arming and firing valves are in the "on" position when perpendicular to the water lines, which is not the industry norm for hydraulic systems. This contributed to the OPF GSE technicians believing they were closing the valves by positioning them perpendicular to the water line when, in fact, they were opening the valves. This misinterpretation resulted in the activation of zones 1,2,3,4, and 5 of the bay 2 Firex deluge system.
