• The Limiting Oxygen Concentration and Flammability Limits of Gases and Gas Mixtures
  6/1/2009 - Peer reviewed journal articles
  This paper presents data on the limiting (minimum) oxygen concentration in the presence of added N₂, methane, propane, ethylene, carbon monoxide, and hydrogen and some of their binary mixtures, and addresses flammable concentration limits.
• Review of the Phoenix of Natural Disasters: Community Resilience
  6/1/2009 - Peer reviewed journal articles
  This article is a review of the book The Phoenix of Natural Disasters: Community Resilience.
• Clearing the Air
  5/1/2009 - Peer reviewed journal articles
  NIOSH research on reducing heavy equipment operator exposure to dust is detailed in this report.
• A Technique for Estimating the Sound Power Level Radiated by Pneumatic Rock Drills and the Evaluation of a CSIR Prototype Rock Drill with Engineering Noise Controls
  5/1/2009 - Peer reviewed journal articles
  This report describes research by NIOSH to reduce the noise exposures of jackleg drill operators and to prevent additional cases of noise induced hearing loss (NIHL) by developing and evaluating low-cost retrofit noise controls for equipment.
• Analyzing Factors Influencing Struck-By Accidents of a Moving Mining Machine by Using Motion Capture and DHM Simulations
  4/1/2009 - Peer reviewed journal articles
  NIOSH researchers used motion analysis data and digital human models to evaluate factors that precipitate struck-by injuries in the operation of remote continuous mining machines.
• Field Evaluation of a Passive Diesel Particulate Filter at a Limestone Mine
  4/1/2009 - Peer reviewed journal articles
  In this study, the operators of a limestone mine retrofitted a loader used for clean-up operations with a passive DPF that was lightly catalyzed and used a fuel additive to initiate regeneration at low exhaust temperatures.
• Identifying Sources of Respirable Quartz and Silica Dust in Underground Coal Mines in Southern West Virginia, Western Virginia, and Eastern Kentucky
  4/1/2009 - Peer reviewed journal articles
  This paper discusses the geochemical analyses which were applied in an effort to identify the specific source rock of respirable quartz dust in coal mines.
• Assessment of Engineering Noise Controls at a Talc Processing Plant
  4/1/2009 - Peer reviewed journal articles
  This report describes an investigation by NIOSH researchers to quantify sound levels and to determine the amount of sound reduction provided by engineering noise controls installed in a talc processing plant.
• Laboratory Evaluation of Smoke Detectors for Use in Underground Mines
  4/1/2009 - Peer reviewed journal articles
  This report describes experiments, their results, and how these results apply to early-warning fire sensors capable of rapid and reliable detection of fires in atmospheres that could be contaminated by either airborne dust or diesel engine products.
• A Revised Conversion Factor Relating Respirable Dust Concentrations Measured by 10-mm Dorr-Oliver Nylon Cyclones Operated at 1.7 and 2.0 L Min^(-1)
  3/1/2009 - Peer reviewed journal articles
  The work presented in this paper focuses on providing a more accurate conversion multiplier than previously reported in the literature, using an independent direct comparison of the 2.0 L and 1.7 L min^(-1) Dorr-Oliver cyclones.
