Real-time diesel particulate monitor for underground mines.

The standard method for determining diesel particulate matter (DPM) exposures in underground metal/ nonmetal mines provides the average exposure concentration for an entire working shift, and several weeks might pass before results are obtained. The main problem with this approach is that it only indicates that an overexposure has occurred rather than providing the ability to prevent an overexp...

Evaluation of a wearable monitor for measuring real-time diesel particulate matter concentrations in several underground mines.

The standard method for determining diesel particulate matter (DPM) exposures in underground metal/nonmetal mines provides the average exposure concentration for an entire working shift, and it can take weeks to obtain results. This approach is problematic because, although it reports that an overexposure has occurred, it fails to provide critical information about cause or prevention. Converse...

Near real time monitoring of diesel particulate matter in underground mines

Studies have linked long-term inhalation of diesel exhaust with adverse health effects such as cardiovascular disease, cardiopulmonary disease, and lung cancer. Diesel exhaust levels in underground mines can approach 100 times the environmental level and are therefore monitored closely in the mining industry. Elemental carbon (EC) (a product of diesel combustion commonly referred to as “soot”) ...

Using Laser Absorption Techniques to Monitor Diesel Particulate Matter Exposure in Underground Stone Mines

Underground miners are exposed to some of the highest levels of diesel particulate matter (DPM) in the United States. Therefore, it is important to monitor the exposure of miners to DPM, but it can be difficult because of the complex composition of DPM and the number of interferences. Currently, elemental carbon (EC) is used as a surrogate because it makes up a significant fraction of the DPM a...

A real-time, wearable elemental carbon monitor for use in underground mines

ICx Technologies is currently fielding a real-time, wearable elemental carbon monitor designed to determine real-time diesel particulate levels in mines. Diesel particulates are composed primarily of elemental and organic carbon and have been found to present a health hazard. Diesel particulate levels can be particularly high in underground mines. The Mine Safety and Health Administration (MSHA...
