    Rautiainen, Risto
    2002/05/01 | National Institute for Occupational Safety and Health (NIOSH)
    This study aimed to describe costs and lost time from injuries and occupational diseases, and to measure the effect of a no-claims bonus intervention using Finnish farmers' workers' compensation data. During 1996, there were 10,092 injuries (7.37/100 workers) and 830 occupational diseases (0.61/100 workers) in a population of 137,002 persons in agr ...

    2002/05/01 | National Institute for Occupational Safety and Health (NIOSH)
    Silicosis and coal workers' pneumoconiosis are complex multifactorial lung diseases whose etiopathogenesis are not well defined. It is generally accepted that fibrotic lung disorders are mediated by macrophage-derived cytokines and growth factors. There is evidence showing a crucial role for tumor necrosis factor-a (TNF-alpha) and interleukin-1 (IL ...

    The Impact of Maintenance and Design for Ventilation Systems
    Estill, Cheryl F. ;
    Hall, Ronald M.
    2002/05/01 | National Institute for Occupational Safety and Health (NIOSH)
    Ventilation systems need to be designed to include access for cleaning and preventive maintenance. Without such access, the exhaust volume will deteriorate. Because of access difficulties and the many demands on their time, plant managers are sometimes errant in performing proper preventive maintenance. Three surveys measuring workers' exposures to ...

    Physiologic Monitoring in Extreme Environments: Application of Micro-Sensors and Embedded Processors to Predict Heat Stress in Fire Fighters
    Bogucki, Sandy ;
    Kolka M
    2002/05/01 | National Institute for Occupational Safety and Health (NIOSH)
    Interior structural firefighting involves heavy physical exertion under extreme environmental conditions. Personal protective clothing and equipment impose 50 lbs of weight on fire fighters and impede the evaporative cooling mechanisms normally responsible for thermoregulation during exercise. The intense heat of the fire ground further exacerbates ...

    2002/05/01 | National Institute for Occupational Safety and Health (NIOSH)
    Gulf War veterans were given pyridostigmine bromide (PB) tablets to enhance the therapeutic effect of antidotes to nerve agents in the event of exposure. The goal of this research is to examine whether combined exposure to PB and sarin (agent GB) is more neurotoxic to sensitive surrogate animals, mice and chickens, than if given separately. Scoping ...

    Boeniger, Mark F. ;
    Klingner TD
    2002/05/01 | National Institute for Occupational Safety and Health (NIOSH)
    Issuing gloves to workers is the most common approach to protecting against skin contact with hazardous chemicals. Typically, glove materials are selected and duration of wear is estimated based on comparisons of laboratory test data. Those who select the glove materials often fail to verify their selections by testing the glove during actual use. ...

    Ruest M
    2002/05/01 | Mining Publications
    Many mines in Canada, the United States and South Africa are reaching the hoisting limit. Very little payload will be possible without compromising safety due to the excessive weight. It has been suggested (DeLorme, 2000) that one of the most attractive concepts to enable deeper hoisting is to reduce the allowable factor of safety in the wire rope. ...

    2002/05/01 | National Institute for Occupational Safety and Health (NIOSH)
    Free radical reactions are believed to play an important role in the mechanism of Cr(VI)-induced carcinogenesis. Most studies concerning the role of free radical reactions have been limited to soluble Cr(VI). Various studies have shown that solubility is an important factor contributing to the carcinogenic potential of Cr(VI) compounds. Here, we re ...

    Farming is the second most hazardous occupation in the U.S. The high mortality rate is due in large part to farm equipment hazards, particularly tractor overturns. Injuries and deaths associated with tractor overturns could be prevented with the use of a rollover protective structure (ROPS). In spite of the known dangers associated with overturn in ...

    A new instrumented cable bolt has been developed by NIOSH at the Spokane Research Laboratory in Spokane WA. Although various instruments are available to measure load distribution and magnitude along a grouted cable, this concept is innovative in that it uses strain gauge technology internal to the cable for the load-measuring sensor. The instrumen ...
