• Flammability of Gas Mixtures Containing Volatile Organic Compounds and Hydrogen
  5/1/2000 - Peer reviewed journal articles
  An experimental program was conducted to evaluate the accuracy of some current methods for predicting the flammability of gas mixtures containing hydrogen and flammable or nonflammable volatile organic compounds (VOCs) in air.
• Flammability of Methane, Propane, and Hydrogen Gases
  5/1/2000 - Peer reviewed journal articles
  This paper reports the results of flammability studies for methane, propane, hydrogen, and deuterium gases in air conducted by the Pittsburgh Research Laboratory.
• Factors Affecting ANFO Fumes Production
  2/1/2000 - Conference papers
  Study of toxic fumes produced by the detonation of various ammonium nitrate/fuel oil (ANFO) mixtures and several cap-sensitive explosives.
• Performance Comparison of Rescue Breathing Apparatus
  10/1/1999 - Reports of Investigations
  A performance comparison of 14 rescue breathing apparatus was undertaken as an assessment of past and present worldwide technology. Rescue breathing apparatus are self-contained, closed-circuit breathing apparatus used for entry into areas having atmosp...
• Prediction of Longwall Methane Emissions: An Evaluation of the Influence of Mining Practices on Gas Emissions and Methane Control Systems
  10/1/1999 - Reports of Investigations
  An analysis of the consequences of increasing longwall panel dimensions, particularly face width, in gassy coalbeds. Continuous longwall face emission monitoring studies were conducted at two adjacent mines operating in the Pocahontas No. 3 Coalbed, whe...
• Proposal for Certification Tests and Standards for Closed-Circuit Breathing Apparatus
  8/1/1999 - Information Circulars
  In this report, recommendations are made to (1) replace the present regulations for certification of closed-circuit breathing apparatus with quantitative tests specifying metabolic work rate rather than activity, (2) continuously monitor relevant physio...
• Comparison of Methane Concentrations at a Simulated Coal Mine Face During Bolting
  4/1/1999 - Peer reviewed journal articles
  An evaluation of strategies for monitoring methane levels during roof bolting in an extended cut entry.
• In-depth Survey Report: Control Technology for Environmental Enclosures - The Effect of Wind Speed Upon Aerosol Penetration Into an Enclosure at Clean Air Filter, Defiance, IA
  2/1/1999 - NIOSH/USBM numbered publications
  The effect of wind speed upon aerosol penetration into an idealized enclosure was studied.
• 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...
• Measuring the Gas Content of Coal: A Review
  2/1/1998 - Peer reviewed journal articles
  Coalbed gas content measurements are commonly used in mine safety as well as coalbed methane resource assessment and recovery applications. Gas content determination techniques generally fall into two categories: (1) direct methods which actually measu...
