Zusammenfassung:For the purpose of alerting an underground miner to life-threatening concentrations of carbon monoxide (CO) a miner's personal CO alarm prototype called PEMCOAL has been developed by the Bureau of Mines. The PEMCOAL unit is small enough to be carried on a miner's belt, has a flashlamp visual alarm, requires to calibration for use, and uses a disk sensor which changes color by reaction with CO. PEMCOAL was tested at concentrations of CO up to 1000 p.p.m., at temperatures from 5 degrees C to 40 degrees C, and with several potential mine gas interferents. The PEMCOAL alarm times are sufficiently fast to warn miners before they are exposed to hazardous quantities of CO.< >
