• Evaluation of Person-Wearable Methane Monitors
  1/1/2005 - Conference papers
  This paper describes test procedures used to evaluate performance of methane monitors that could be used underground for continuous personal monitoring of methane. The information in this report provides data that allow the reader to make side-by side c...
• NIOSH Research in Coal Dust and Explosions
  10/1/2004 - Conference papers
  The NIOSH mining research program at the Pittsburgh Research Laboratory (PRL) includes the areas of coal mine dust control and monitoring, and explosion prevention.
• Use of a Test Box to Measure Response Times for Machine-Mounted Monitors
  5/1/2004 - Conference papers
  This study describes how response times of machine-mounted methane monitors were measured by placing the methane sensor heads in a specially designed box where they were exposed to an atmosphere containing a constant concentration of methane.
• Fugitive Carbon-Based Gases: Blasting Related or Not
  2/1/2004 - Conference papers
  This paper discusses elements of a stray gas investigation and the analyses necessary to identify the source of a stray gas.
• CO Migration from Trench Blasting in Amherst, New York
  2/1/2004 - Conference papers
  A general overview of the blasting and CO monitoring of a highway construction project is presented and discussed. The use and effectiveness of residential type CO monitors and multi-gas monitors are discussed.
• Blasting-Related Carbon Monoxide Incident in Bristow, Virginia
  2/1/2004 - Conference papers
