    Impact of Control Parameters on Shearer-Generated Dust Levels
    Colinet, Jay F. ;
    Prokop AE
    2001/02/01 | Mining Publications
    Previous research on continuous mining operations has shown that significant interactions exist between dust-control parameter application and the resulting respirable dust levels. However, simply increasing the level of the controls does not guarantee a reduction in respirable dust levels. Full-scale laboratory tests are being conducted to provide ...

    Harris JR
    2001/02/01 | National Institute for Occupational Safety and Health (NIOSH)
    In the U.S., approximately 132 agricultural tractor overturn fatalities occur per year. The use of rollover protective structures (ROPS), along with seat belts, is the best-known method for preventing these fatalities. However, one impediment to ROPS use is low-clearance situations, such as orchards and animal confinement buildings. To address the ...
