• CO Dispersion from a Coal Fire in a Mine Entry
  6/1/2006 - Conference papers
  Five mine fire experiments were conducted in a 2.08-m-high, 2.90-m-wide ventilated mine entry in NIOSH's Safety Research Coal Mine to determine the effect of the dispersion of carbon monoxide (CO) on mine fire detection.
• 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

• NIOSH Hazard ID 3 - Carbon Monoxide Poisoning and Death After the Use of Explosives in a Sewer Construction Project
  3/1/1998 - Hazards IDs
  In a recent incident, three cases of CO poisoning in a confined space, including one fatality, were caused by CO migrating through soil after nearby use of explosives during a municipal sewer project. This incident illustrates that CO from subsurface de...
• A 20-Liter Furnace Test Method to Determine the Combustion Gas Toxicity of Conveyor Belts
  1/1/1996 - Reports of Investigations
  Pittsburgh Research Center conducted experiments with mine conveyor belt samples in a 20-L furnace and in a laboratory fire tunnel to measure and compare the major toxic gas concentrations evolved during the combustion of the materials.
• Evaluation of Smoke Detectors for Mining Use
  1/1/1995 - Reports of Investigations
  The U.S. Bureau of Mines has constructed a smoke chamber and developed sensitivity tests for smoke detectors. Evaluation of six smoke detectors showed their potential for use as mine fire sensors or as part of a mine atmospheric monitoring system.
