First Air-Foam Sprinkler Installed in Airline Hangar
“Automatic” Sprinkler Corporation of America recently installed the world’s first air-foam sprinkler system in a commercial airline hangar, it is claimed. In a six-minute acceptance test in Canadian Pacific Airline’s 36,000-square-foot Vancouver hangar, 450 of the system’s 600 foam-water sprinkler heads were used to discharge 220,000 gallons of air foam, covering the whole area with a 6-inch-thick blanket of foam which remained until washed away with fire hoses.
Although not mandatory for minimum building protection under N.F.P.A. standards, the air-foam installation was made because the hangar often contains as many as three $3.5 million Bristol Britannias carrying up to 16,000 gallons of fuel each.
“Automatic” has available a 15-minute, color, sound film, showing the actual operation of a 60,000-gpm mechanical foam-water system. The film also portrays the advantages of such a system applicable in the chemical, utility, aircraft and general manufacturing industries where the use of flammable liquids present special hazards. Requests for viewing, and inquiries concerning the film, should be directed to R. J. Buchanan, manager special hazards, the “Automatic” Sprinkler Corporation of America, Youngstown, Ohio.
