Evaluation of the Range Queen Kitchen Range Fire Extinguishing Device.

摘要

A full-scale performance evaluation of the Range Queen kitchen range fire extinguishing device was conducted. Test conditions were selected to be typical of field situations. A full-scale mock-up of a typical military family housing kitchen was constructed specifically for this test series. The kitchen mock-up consisted of a range with an externally vented hood, both upper and lower cabinets with a counter top, and a partial ceiling. Tests were conducted using both electric and gas ranges. Six different cooking vessels were used for the tests. Tests were conducted using both vegetable oil and peanut oil as the fuel. Oil depths varied from 1/2 inch to 2 inches, depending on pay type. Range Queen extinguisher performance was found to be a function of several variables, including: range type (gas, electric), characteristics of the cooking vessel (geometry, size, material), burner size, burner location (front, rear), quantity of oil, cause of ignition, and extinguisher placement. More than 130 range-top fire tests were conducted to characterize the influence of each of these variables.
