    Lim SY ;
    Murphy, Lawrence R.
    1999/09/01 | National Institute for Occupational Safety and Health (NIOSH)
    Certain organizational factors appear to play a crucial role in promoting both employee health and well-being, and organizational effectiveness. The consistent predictors of health and performance outcomes from this study form the core of a model of healthy work organizations. Future work will consist of validating the healthy work organization mod ...

    Niu T
    1999/09/01 | National Institute for Occupational Safety and Health (NIOSH)
    Background: Serum paraoxonase has been associated with the metabolism of organophosphate pesticides in humans. Molecular analysis of the human paraoxonase gene (PON1) has revealed that Arg192 homozygotes have a greater detoxifying capability than Gln192 homozygotes. We examined the effects of PON1 genotypes on male reproductive outcomes and its int ...

    Castranova, Vincent
    1999/09/01 | National Institute for Occupational Safety and Health (NIOSH)
    The blasting process changed the trace metal content of all blasted particles. Blasting generally increased the relative proportion of iron in blasted materials. This iron was apparently derived from the steel plates that were being blasted. Blasting also resulted in the generation of particles with an average diameter on one micro-m. Both fresh an ...

    1999/09/01 | National Institute for Occupational Safety and Health (NIOSH)
    Although chance effects could be excluded only for the confusion scale and environmental stuffiness, enhanced particle filtration in this building was associated with small improvements in 10 of the 13 worker outcome measures. Findings of only slight beneficial effects from removing small airborne particles in this building may not apply to buildin ...

  • Risks of Fatal Injuries to Farm Workers 55Years of Age and Older
    Risks of Fatal Injuries to Farm Workers 55-Years of Age and Older
    Casini, Virgil J. ;
    Cianfrocco R
    1999/09/01 | National Institute for Occupational Safety and Health (NIOSH)
    The results of this analysis confirm previous studies that have shown older workers to be at the highest risk for occupational injuries within the agricultural production industry (Purschwitz and Field, 1986: Murphy, 1990; Myers and Hard, 1995). The identification of farm tractors as the leading cause of these fatalities has also been previously re ...

    1999/09/01 | Health Hazard Evaluation Reports (HHE)
    On January 16, 1998, the National Institute for Occupational Safety and Health (NIOSH) received a request for a health hazard evaluation (HHE) from employees working at the U.S. Postal Service Vehicle Maintenance Facility located in Chicago, Illinois. The request stated that employees were experiencing headaches, sneezing, coughing, unspecified res ...

    1999/09/01 | Mining Publications
    High-impedance arcing faults are difficult to detect with conventional switchgear, and the presence of these faults in coal mine power systems represents a significant fire hazard. Research was performed to identify plausible techniques that would discriminate between the high-impedance arcing faults and legitimate load currents on the dc trolley s ...

    Safety Climate Dimensions Associated with Occupational Exposure to Blood-Borne Pathogens in Nurses
    DeJoy DM ;
    Gershon RRM
    1999/09/01 | National Institute for Occupational Safety and Health (NIOSH)
    These findings are consistent with those from previous research (DeJoy et al., 1995; Gershos et al.,; Murphy et al., 1996) and additionally suggest that safety climate plays a larger role in a nurse's compliance with universal precautions (UP) than it does in accidents/injuries. This may be partly due to the relatively low base rate associated with ...

  • Occupational Injury Fatalities Among Older Workers in the United States 19801994
    Occupational Injury Fatalities Among Older Workers in the United States, 1980–1994
    Kisner, Suzanne M. ;
    Pratt, Stephanie G.
    1999/09/01 | National Institute for Occupational Safety and Health (NIOSH)
    The elevated fatality rates among older workers are more striking if full- and part-time status is considered. In 1990, workers aged 65 and older in non-agricultural industries worked an average of 29 hours a week, whereas workers aged 20 to 64 worked an average of 37-41 hours a week (BLS, 1991). If decreased exposure time were taken into account, ...
