4/1/2005 - Peer reviewed journal articlesDiscusses a study that used a CFD program (fire dynamics simulator) based on large eddy simulations (LES) to model floor-level fires in a ventilated tunnel. The CFD results are compared with two simple theories of critical ventilation.
4/1/2005 - Peer reviewed journal articlesA diesel particulate matter analyzer capable of direct, real-time measurement of engine exhaust particulate is necessary to effectively institute source control technology currently being used on diesel equipment and to ensure that the control measures ...
3/1/2005 - Peer reviewed journal articlesThis paper highlights some of the widely used standards for accurate flammability and ignitability data for chemicals, complemented with hypothetical but relevant examples describing the testing strategy, interpretation, and application of the results.
3/1/2005 - Peer reviewed journal articlesA major focus of ground control research presently being conducted by the Spokane Research Laboratory of the National Institute for Occupational Safety and Health (NIOSH) is to incorporate weak rock masses (such as are associated with operations in the ...
This study's objective was to simulate the postures and loads experienced by the lumbar spine during repetitive lifting of weights in different torso flexion postures, and to analyze the fatigue failure response of lumbosacral motion segments.
This field study encouraged coal miners in WV and PA to engage in hearing protection behaviors. Responses from 307 coal miners showed that positive or neutral messages generated more self-reported hearing protection behaviors than negative messages.
This publication details a series of explosive detonation experiments conducted in NIOSH's Bruceton and Lake Lynn Experimental Mines to evaluate low-level (<6 psig) detonation wave propagation behavior in single- and multiple-entry configurations.
Investigates the ability of the SKC DPM cassette to collect diesel particulate matter while segregating ore dust from the sample.
Physical Limitations and Musculoskeletal Complaints Associated With Work in Unusual or Restricted Postures: A Literature ReviewThis paper argues that workers who adopt unusual or restricted postures appear to be at higher risk of musculoskeletal complaints and often exhibit reduced strength and lifting capacity.
Reducing Enclosed Cab Drill Operator's Respirable Dust Exposure with Effective Filtration and Pressurization TechniquesDiscusses a cooperative research effort to lower respirable dust levels in an enclosed cab on an older surface drill at a silica sand operation. A number of modifications were incorporated into the drill's filtration and pressurization system, as well a...
