Oil Fire Extinguished by Artificial Fog
Representatives of fire departments in Los Angeles County, Cal., witnessed a demonstration of a new device for extinguishing oil fires, at Sante Fe Springs, Cal. At the demonstration, an oil tank fire covering 180 square feet area was extinguished with three gallons of water in a short period of time.
The “Rapid” method consists of breaking up a solid stream of water into minute fog particles. In the process of absorbing heat from the fire, steam is generated in the space between the fire and the burning material, thus excluding the oxygen that is necessary to support combustion.
The fire chiefs attending the demonstration at Santa Fe Springs included Deputy Chief J. J. Davis, First Assistant County Fire Warden, Los Angeles County; Assistant Chief Norman C. Johnson, Los Angeles County Fire Department; Robert I., Dunlap, Chief of Fire Prevention, Los Angeles County; Battalion Chief A. Heizman, Los Angeles County Fire Department, and Captain Glenn C. Griswold, Los Angeles County Fire Department, Santa Fe Division.
