Using Handheld Infrared Imagers to Locate Miners in Smoke-Filled Mine Openings
Two infrared imagers, both with a 3- to 5-micrometers spectral range, have been tested in a smoke-filled opening to determine their capability to 'see through smoke.' A mine opening 75 meters long was filled with coal smoke. A fire in a smoke generator and two men were used as targets. The men were detected and identified at 75 meters. Tests were discontinued on the fire because the instruments were saturated with the fire at 25 meters indicating that fire could be detected at much greater distances. Because of their ability to 'see through smoke,' infrared imagers appear to be useful tools during rescue operations in smoke-filled mines.
