• A Performance Evaluation of Two Overhead Power Line Proximity Warning Devices
  11/1/2008 - Information Circulars
  The results of NIOSH's test of two commercially available proximity warning devices (PWDs) are presented. PWDs warn personnel if mobile equipment moves within some preselected minimum distance of an energized overhead electrical power line.
• The Status of Mine Fire Research in the United States
  9/1/2008 - Conference papers
  This paper summarizes recent accomplishments in a research program that is addressing mine fire prevention, detection, management, and suppression, and provides an overview of the next phase of the NIOSH mine fire research program.
• Technology News 455 - Roof Hazard Alert Modules
  5/1/1997 - Technology News
  The new permissible-type, intrinsically safe design modules described here represent an engineering intervention strategy toward improving miners' ability to recognize and avoid the hazardous zone of unsupported mine roof.
• Fire Detection for Conveyor Belt Entries
  1/1/1991 - Reports of Investigations
  This report details the results of a series of large-scale experiments where small coal fires were used to ignite the conveyor belt at specific air velocities, and showed conditions required for early detection of conveyor belt entry fires.
• Evaluation of Smoke and Gas Sensor Responses for Fires of Common Mine Combustibles
  3/1/2015 - Peer reviewed journal articles
  An article detailing experiments conducted to evaluate the response characteristics of commercially available gas, smoke and flame sensors to fires of common combustible mine materials.
• Intelligent Proximity Detection to Improve Miner Safety
  9/28/2012 - News articles
  NIOSH is developing a prototype intelligent system that provides enhanced protection by continuously monitoring miners’ positions in relation to the machine and established safety zones.
• Rapid Detection and Suppression of Mining Equipment Cab Fires
  4/1/2010 - Peer reviewed journal articles
  This paper discusses large-scale experiments conducted by NIOSH to evaluate the effectiveness of optical flame detectors, photoelectric smoke detectors, and combined ionization/photoelectric smoke detectors for detecting mining equipment cab fires.
• In-Mine Evaluation of Smart Mine Fire Sensor
  12/1/2008 - Peer reviewed journal articles
  This paper describes the in-mine evaluation of a smart mine fire sensor system and discusses recommendations for improving the system.
• 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.
• 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...
