METHOD OF HANDLING OIL FIRES DEMONSTRATED BY PRACTICAL TEST
Andyco Foam Generator Using Foam Powder and Water Puts Out Fire in One and One-Half Minutes
A VERY satisfactory oil fire test was conducted at Wilming Delaware, on December 18, 1925, before the Flammable Liquids Committee of the National Fire Protection Association and representative of several oil companies.
The arrangement for extinguishing the fire with Amdyco continuous foam generators and Amdyco Foam Powder were as follows:
Chief W. J. Lutz of the Wilmington Fire Department was in charge of the demonstration and provided a pumper used to raise the water pressure from the hydrant to 150 pounds after which the water was sent through 450 feet of 2 1/2 inch hose to a twoway gate. From this gate two 50-foot sections connected the line two standard Amdyco Continuous Foam Generators operating at a water pressure of approximately 80 pounds per square inch. The foam line from each generator consisted of 100 feet of standard 2 1/2 inch rubber lined fire hose equipped with nozzle.
The nozzle men on the first line were Lieutenant Revis and Firemen E. Gibson and C. Wallace; and on the second line, Lieutenant Byrne and Firemen Greaves, Mutschler, Lux and Harkness. Assisting Firemen T. P. Plummer and W. G. Ray attended the two Amdyco Continuous Foam Generators.
It was the desire of the Amdyco Company to have men other than their organization men run these tests to demonstrate that the apparatus is simply operated and that no special training or knowledge is necessary.
A pit measuring between 40 and 50 feet in diameter was partly filled with water and on which was discharged 2,720 gallons of crude oil, gasoline and kerosene in proportions corresponding to Pennsylvania crude oil. The oils which went into the mixture included 15% gasoline, United States Navy specification: 15% kerosene, 44 gravity, 140 Hash; 15% gas oil. 36 gravity, 200 flash; 55% heavy fuel oil, 15 gravity, 275 flash.
The oil was ignited and allowed to burn for 10 minutes before the signal to commence the test was given. In one minute and ten seconds after Chief William J. Lutz gave the order to generate foam, the fire was under control, and in one minute and thirty seconds was completely extinguished.
It was remarked at the demonstration that inasmuch as this was the first time these firemen had ever handled the Amdyco Foam Powder and the Amdyco Continuous Foam Generator, it spoke well for the simplicity of the system.
After extinguishing the tire a Super-Generator was operated discharging foam through four sections of 6-inch pipe. This pipe may be seen in one of the photographs herewith and was installed for demonstrating the practicability of connecting the Amdyco Continuous Foam Generator to permanent piping for conveying foam to tanks.
A brief description of the Amdyco Continuous Foam Generator may be of interest. While at this test the Amdyco Continuous Foam Generator was operated at a water pressure of 80 pounds per square inch, it will operate through a range of 35 pounds to over 150 pounds. Amdyco Foam Powder fed into the hopper of the generator is drawn into the water jet resulting in a chemical action producing a foam of any desired consistency in the foam lines by adjustment. One pound of Amdyco Foam Powder when mixed in the proper way with one gallon of water will produce foam in excess of the product of a gallon of combined solutions as used in the two solution foam system.
Amdyco Foam Powder is supplied in hermetically sealed tins of convenient size with covers specially devised for immediate easy removal. This keeps the powder absolutely dry. The powder is not affected by frost.
It was the consensus of opinion that the test was one of the most severe ever staged in the history of oil fire prevention to determine the effectiveness of the extinguishing apparatus.
