Abstract
To improve the fire safety of spring bed mattress, a cooling frame including cooling material (water) was made and a cooling frame was installed under the bed mattress or between the bed mattress and bed mattress base; fire tests (real scale) were conducted with or without a cooling frame. Similar fire behavior was observed at the beginning of the test (approximately 3 minutes). Subsequently, rapid fire growth in the mattress without a cooling frame, but with a cooling frame, the decline progressed without growth. The flame spread on the top surface of the bed mattress was similar in the semicircular direction, and the average flame speed velocity was analyzed at approximately 0.005 m/s. The maximum flame height was found to be approximately 2.7 m without a cooling frame, and approximately 1.8 m with a cooling frame installed. In addition, the maximum heat release rate was measured to be approximately 740 kW without a cooling frame, and approximately 400 kW with a cooling frame installed. As a result, the flame height and heat release rate were reduced when the bed mattress was fired through the installed cooling frame.
