  • A Method for Reducing Adaptor Misalignment When Testing Gloves Using ISO 10819
    A Method for Reducing Adaptor Misalignment When Testing Gloves Using ISO 10819
    Dong, Ren G. ;
    Han B
    2002/04/01 | National Institute for Occupational Safety and Health (NIOSH)
    International standard ISO 10819 was established in order to quantify the vibration attenuation characteristics of anti-vibration gloves. One problem that exists with the standard is possible misalignment of the palm adaptor that is placed underneath the test glove. If the adaptor becomes misaligned, the measured glove transmissibility will be lowe ...

    Heavy Equipment Near Overhead Power Lines? New Safety Research May Save Your Life
    Cawley, James C. ;
    Homce, Gerald T.
    2002/04/01 | Mining Publications
    The mining industry has a relatively small number of electrical injuries, compared to industries such as construction or agriculture, due to the small total employment in mining. Mining does, however, have one of the highest occupational electrocution rates of any U.S. industry, at 2.8 for every 100,000 workers per year. This is approximately four ...

    2002/04/01 | Grant Final Reports
    Environmental health policy in the United Sates is shifting from the paradigm of control to that of prevention. Under the control paradigm, harmful substances are dealt with only after their production or acquisition. In contrast, the prevention paradigm seeks to change the processes by which goods or services are produced in order to achieve the s ...

    The objective of this research was to determine the spatial distributions of childhood lead poisoning and soil lead contamination in urban Tijuana. The Bocco-Sanchez model of point-source emissions was evaluated in terms of validity and reliability. We compared the model's predicted vulnerable populations with observed cases of childhood lead poiso ...

    2002/04/01 | National Institute for Occupational Safety and Health (NIOSH)
    Our earlier studies have shown that the electrostatic collection technique, a potentially "gentle" bioaerosol collection method, allows for efficient collection of airborne bacteria, but sensitive bacteria such as Pseudomonasfluorescens (P.fluorescens) lose their culturability during collection. We hypothesized that excessive stress was imposed on ...

    Shi X
    2002/04/01 | National Institute for Occupational Safety and Health (NIOSH)
    Epidemiological and animal studies suggest that several metals and metal-containing compounds are potent mutagens and carcinogens. These metals include chromium, arsenic, vanadium, nickel, and others. During the last two decades, chemical and cellular studies have contributed enormously to our understanding of the mechanisms of metal-induced pathop ...

    2002/04/01 | National Institute for Occupational Safety and Health (NIOSH)
    The prevalence of depression is increased in certain chronic conditions but has not been well studied in asthma. We estimated the prevalence of depressive symptoms (DEP _SX) among a group of adults with asthma. We analyzed cross-sectional data from an ongoing study of adults with asthma surveyed by telephone (n=439). The CES-D (score range 0-60) wa ...

    Prolonged exposure to hand-transmitted vibration can cause debilitating neural and vascular dysfunction in humans. It is unclear whether the pathophysiology involves simultaneous or sequential injury of arteries and nerves. The mechanism of vibration injury was investigated in a rat tail model, containing arteries and nerves structurally similar to ...

    To examine the effect of exposure to gassings of ozone, chlorine dioxide, or sulphur dioxide on rhinitis onset among pulp mill workers. Workers from two sulphate pulp mills (n=I04) and two control paper mills, which had no gassing events (n=68), were included in the study. Rhinitis was self- reported and defined as ever having, since age 15, nasal ...

    2002/04/01 | Mining Publications
    The new MSHA diesel rules have stone mine operators looking hard at possible upgrades to their ventilation systems. There are existing methods to reduce diesel engine emissions (MSHA, 2001)(Head, 2001b), but many operators will decide that a ventilation upgrade is necessary as well. NIOSH has several stone mine ventilation projects underway, but in ...

    Hidden within the pastoral setting of rural America are the struggles of farm families who must cope with a decreasing economy, increasing technology, and one of the highest injury rates of any industry. Wives of farmers often juggle household responsibilities, hold an off-farm job, and work on the farm. Too often, wives are first on the scene of a ...

    2002/04/01 | National Institute for Occupational Safety and Health (NIOSH)
    Exposure to ozone (O3), a major air pollutant in urban areas, induces airway hyperresponsiveness mediated partly by the release of tachykinins from nerve terminals of intrinsic airway ganglia (Wu et. al., J. Appl. Physiol. 91:371-378, 2001). The purpose of this study was to investigate the possible involvement of intrinsic airway neurons in O3-indu ...
