• Technology News 528 - Recirculation Filter Is Key to Improving Dust Control in Enclosed Cabs
  10/1/2007 - Technology News
  NIOSH has investigated various cab filtration system factors on a basic HVAC system in the laboratory to evaluate their effects on overall cab dust protection performance.
• Closing the Door to Dust When Adding Drill Steels: Uni-directional Cab Filtration and Pressurization System Tested
  10/1/2007 - Peer reviewed journal articles
  During a recent NIOSH field evaluation of a newly designed filtration and pressurization system for an enclosed cab of a surface drill, it was determined that the drill operator's respirable-dust exposure was significantly increased during time periods ...
• In-Cab Noise Reduction on an Air-Rotary Drill Rig
  5/1/2007 - Peer reviewed journal articles
  This paper summarizes a NIOSH investigation of engineering noise controls to reduce sound levels in cabs on air-rotary drill rigs. Results revealed that some drillers are exposed to A-weighted sound levels exceeding 85 dB even though a cab is used.
• Improving Silica Dust Controls for Metal/Nonmetal Mining Operations in the United States
  4/1/2007 - Conference papers
  NIOSH researchers are improving protection provided by enclosed cabs on mining equipment, reducing dust generation from surface drills, reducing dust levels in iron ore operations, and developing a new method to clean dust from soiled clothes.
• Effectiveness of Various Concentrations of an Inert Gas Mixture for Preventing and Suppressing Mining Equipment Cab Fires: Development of a Dual-Cab Fire Inerting System
  3/1/2007 - Peer reviewed journal articles
  NIOSH conducted large-scale experiments to evaluate the effectiveness and safety of various concentrations of an inert gas mixture for preventing and suppressing cab fires. This has led to the choice of an optimum gas mixture concentration.
• A New Concept for Leak Testing Environmental Enclosure Filtration Systems
  11/1/2006 - Peer reviewed journal articles
  A method (patent pending) has been developed to determine the quality of environmental cab filtration systems. It utilizes specially configured filter cartridges to remove carbon dioxide from the ambient air with the environmental cab's air filtration s...
