  • Preventing Tractor Rollover Fatalities Performance of the NIOSH AutoROPS
    Preventing Tractor Rollover Fatalities: Performance of the NIOSH AutoROPS
    Etherton, John R. ;
    Harris JR
    2001/09/01 | National Institute for Occupational Safety and Health (NIOSH)
    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. One impediment to ROPS use, however, is low clearance situations, such as orchards and animal confinement buildings. To address the need for ROP ...

    Roy D ;
    Thomas RD
    2001/09/01 | National Institute for Occupational Safety and Health (NIOSH)
    We have previously demonstrated that diethylstilbestrol is metabolized to diethylstilbestrol reactive metabolites by mitochondrial enzymes in vitro. In vitro, these reactive intermediates bind to mitochondrial DNA. Here we have investigated the in vivo formation of diethylstilbestrol adducts with mitochondrial DNA and the nature of mitochondrial DN ...

    Public health approaches to occupational injury prevention: do they work
    Smith GS
    2001/09/01 | National Institute for Occupational Safety and Health (NIOSH)
    Occupational injuries represent a considerable part of the injury burden to society, affecting people in the most productive years of their lives. Globally, almost 1000 workers are killed by injuries every day, and about six of every 1000 workers will be fatally injured at work during a 40 year work life span.(1) Non-fatal injuries are an even more ...
