MSHA Altair Gas Monitors

Working in a coal mine subjects personnel to a harsh environment where the average mine height is approximately 42 inches, there is no light, the surfaces are wet and slippery, and the average temperature is approximately 55 degrees. The environment may contain methane and other harmful gasses. Mine Safety and Health Administration (MSHA) must be prepared to monitor the working environment of the mines in order to determine if the concentration of harmful or noxious gasses is being effectively controlled by the measures utilized by the mine operator. The unit used to measure these gasses underground must be MSHA approved as intrinsically safe. Daily bump testing using a calibration station is required to ensure the unit is properly calibrated. Moreover, space and weight concerns are of par
