Spontaneous Ignition Temperature of Tracheal Tubes
註釋Operating room fires continue to be reported in the medical literature. To simulate operating room conditions, a high pressure spontaneous ignition apparatus was redesigned to allow for the determination of spontaneous ignition temperature of trachea! tubes in 100% oxygen at atmospheric pressure. Pure oxygen flowed through a test chamber at 100 cm3/min, and a temperature ramp rate of 10°C/min was used. Sample temperature, chamber temperature, chamber pressure and elapsed time were stored on-line by computer. The experimental ignition temperature was observed as a spike in sample temperature-time plot.
