• The Role of ASTM E27 Methods in Hazard Assessment: Part II - Flammability and Ignitability
  3/1/2005 - Peer reviewed journal articles
  This 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.
• Empirical Approaches for Opening Design in Weak Rock Masses
  3/1/2005 - Peer reviewed journal articles
  A 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 ...
• Torso Flexion Loads and Fatigue Failure Mode of Human Lumbosacral Motion Segments
  1/1/2005 - Peer reviewed journal articles
  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.
• Using Persuasive Messages to Encourage Voluntary Hearing Protection Among Coal Miners
  1/1/2005 - Peer reviewed journal articles
  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.
• Detonation Wave Propagation in Underground Mine Entries
  1/1/2005 - Peer reviewed journal articles
  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.
• Sampling Results of the Improved SKC® Diesel Particulate Matter Cassette
  1/1/2005 - Peer reviewed journal articles
  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 Review
  1/1/2005 - Peer reviewed journal articles
  This 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 Techniques
  1/1/2005 - Peer reviewed journal articles
  Discusses 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...
• Assessment of Noise Controls Commonly Used on Jumbo Drills and Bolters in Western United States Underground Metal Mines
  1/1/2005 - Peer reviewed journal articles
  The noise-control treatments most commonly observed on drills and bolters during this study were evaluated on machines at underground metal mines to determine the amount of noise reduction achieved by each control.
• Noise and Vibration Reduction of a Vibrating Screen
  1/1/2005 - Peer reviewed journal articles
  This paper reports on a cooperative study on vibrating screen noise conducted at a coal preparation plant. Rubber isolators were found to reduce sound levels by 1 dB and amped side plates reduced vibration levels on the screen sides by 1 to 7 dB(A).
