8/1/2007 - Peer reviewed journal articlesThis article examines the spatial variability of dust concentrations within a coal miner’s breathing zone and the impact of sampling location at the cap lamp, nose, and lapel.
-
7/1/2007 - Peer reviewed journal articlesResearchers at NIOSH have long used stationary tapered element oscillating microbalances (TEOMs®) in laboratory settings. They have served to assess the mass concentration of laboratory-generated particulates in experimental dust chambers and ...

6/1/2006 - Conference papersThe results of a series of tests in an underground mine were used to evaluate several measurement methods that are currently used to characterize particulate matter emitted by diesel-powered equipment. This paper presents an overview of these techniques...

6/1/2006 - Peer reviewed journal articlesRecent advances in technology have enabled the development of a small, portable, data-logging particle monitor, modified from commercial smoke alarm technology, that can meet the needs of surveys in the developing world at reasonable cost.
-
6/1/2006 - Conference papersElemental carbon (EC) is used as a surrogate for regulating the exposure to diesel particulate matter (DPM) of underground metal/nonmetal miners. Currently, EC represents DPM well in underground mines. Some control technologies have been shown to possib...

The Effects of Water Spray Placement for Controlling Respirable Dust and Face Methane Concentrations4/1/2006 - Peer reviewed journal articlesA series of laboratory evaluations examined the impact of water spray pressure, curtain setback distance, and external and underboom spray use for controlling respirable dust levels and sulfur hexafluoride tracer gas concentrations around a continuous m...
-
1/1/2006 - Peer reviewed journal articlesSince 1982, standard calibration materials recommended for respirable crystalline silica analysis by the Mine Safety and Health Administration (MSHA) P7 Infrared Method and the NIOSH X-ray Diffraction (XRD) Analytical Method 7500 have undergone minor ch...
-
7/1/2005 - Conference papersThis manuscript will discuss five different research studies conducted by the National Institute for Occupational Safety and Health (NIOSH) which use ventilation in some application to lower workers' respirable dust exposures at surface and metal/nonmet...
