• Recommendations for Evaluating & Implementing Proximity Warning Systems on Surface Mining Equipment
  6/1/2007 - Reports of Investigations
  NIOSH studied technology and methods that could reduce accidents involving surface mining equipment. These proximity warning systems included radar, sonar, GPS, radio transceiver tags, and combinations of radar and cameras.
• 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.
• Recommendations for Testing Radar-Based Collision Warning Systems on Heavy Equipment
  5/1/2002 - Reports of Investigations
  This report discusses several different test procedures and test targets and recommends methods to determine how effective a radar system will be in detecting a person near heavy equipment.
• Test Results of Collision Warning Systems on Off-Highway Dump Trucks: Phase 2
  2/1/2001 - Reports of Investigations
