2/1/2003 - Peer reviewed journal articlesA performance criterion is described that identifies sincere vs insincere group membership during functional evaluations of dynamic trunk motion performance. Examiners evaluated participants to quantify inter-rater and test-retest reliability.
1/1/2003 - Peer reviewed journal articlesNIOSH, in collaboration with the Mine Safety and Health Administration, the mining industry, and seal manufacturers, conducted a series of full- scale experiments to evaluate the explosion-resistant characteristics of several new seal designs for rapid ...
1/1/2003 - Peer reviewed journal articlesThis paper presents the results of testing of the Dynamic Component Program model with the ISC3 model of predicting dispersion of dust from haul trucks at two surface mine sites.
10/1/2002 - Peer reviewed journal articlesThis paper reports the results of a study performed to evaluate ergonomic exposures among operators of heavy construction equipment. It also provides recommendations for reducing ergonomic exposures such as vibration and postural stress.
The Use of Light Scattering and Ion Chamber Responses for the Detection of Fires in Diesel Contaminated Atmospheres6/1/2002 - Peer reviewed journal articlesExperiments were conducted to determine the optical scattering properties of diesel particulate matter (DPM) and various combustion aerosols from both flaming and smoldering combustion sources at discrete angles of 151 and 301 in the forward direction...
6/1/2002 - Peer reviewed journal articlesThe amount of airborne respirable dust generated from breakage of different coals varies widely. This research was conducted to identify the facets of airborne respirable dust liberation from the coal product.
Heavy Equipment Near Overhead Power Lines? New Safety Research May Save Your Life: New Safety Research May Save Your Life4/1/2002 - Peer reviewed journal articlesResearchers at the NIOSH Pittsburgh Research Laboratory are developing an overhead electric power line-contact alarm for mobile equipment.
4/1/2002 - Peer reviewed journal articlesThis study evaluated spinal loads associated with lifting and hanging heavy mining cable in a variety of postures.
Differential Pressure Response of 25-mm-Diameter Glass Fiber Filters Challenged with Coal and Limestone Dust Mixtures2/1/2002 - Peer reviewed journal articlesThis article summarized results of research conducted by the National Institute for Occupational Safety and Health (NIOSH) at its Pittsburgh Research Laboratory. The objective of this work was to determine the correlation between the mass (M) of respir...
Inaccuracy of Area Sampling for Measuring the Dust Exposure of Mining Machine Operators in Coal Mines2/1/2002 - Peer reviewed journal articlesThis study examines the accuracy of area sampling for measuring the dust exposure of mining machine operators at coal mine working faces. The work was prompted by the development of a prospective new type of dust sampling instrument called the machine-...
