    Quiet Death on the Lake-Outdoor Boat-Related Carbon Monoxide Poisonings Recognized at Lake Powell
    Baron R ;
    Mccammon J
    2002/05/01 | National Institute for Occupational Safety and Health (NIOSH)
    The rapid fatal poisoning of two brothers (aged 8 and 11) who were swimming at the back of their family's houseboat on Lake Powell led to a Federal investigation of fatal and non-fatal boat-related carbon monoxide (CO) poisonings. The boys' deaths, occurring in August 2000, were the eighth and ninth fatal boat-related CO poisonings occurring on Lak ...

    Worker Health Chartbook, 2000: Fatal Injury
    National Institute for Occupational Safety and Health
    2002/05/01 | NIOSH Numbered Publications
    Current occupational safety surveillance data reveal staggering human and economic losses associated with fatal occupational injury - about 17 workers were fatally injured on the job each day during 1997. Understanding and preventing such losses require focused efforts to quantify and track occupational fatalities and their associated conditions. M ...

    Improving the Use of Mixing Factors for Dilution Ventilation Design
    Bennett JS ;
    Feigley CE
    2002/05/01 | National Institute for Occupational Safety and Health (NIOSH)
    In specifying dilution ventilation flow rate, a safety factor, K, is often used to provide a margin of safety and to compensate for uncertainties and health impact severity. In current practice, the selection of K is very subjective. Here the component of K accounting for imperfect mixing, Km, was studied to develop more effective and efficient des ...

    2002/05/01 | National Institute for Occupational Safety and Health (NIOSH)
    We studied the effects of removing small airborne particles in an office building without unusual contaminant sources or occupant complaints. We conducted a double-blind crossover study of enhanced particle filtration in an office building in the Midwest United States in 1993. We replaced standard particle filters, in separate ventilation systems o ...

    2002/05/01 | National Institute for Occupational Safety and Health (NIOSH)
    From 1990 to 2000, a total of 111 carbon monoxide (CO) poisonings occurred on Lake Powell near the Arizona and Utah border. Seventy-four of the poisonings occurred on houseboats, and 64 were attributable to generator exhaust alone. Seven of the 74 houseboat-related CO poisonings resulted in death. Although many of the reported CO poisonings occurre ...

    The present study investigated the differential requirement of ROS in UV-induced activation of these pathways. Exposure of the mouse epidermal C141 cells to UV radiation led to generation of ROS as measured by electron spin resonance (ESR) and by H2O2 and O2. fluorescence staining assay. Treatment of cells with UV radiation or H2O2 also markedly ac ...

    2002/05/01 | National Institute for Occupational Safety and Health (NIOSH)
    NIOSH researchers evaluated the ability of fifth-generation dry-cleaning machines to control occupational exposure to perchloroethylene (PERC). Use of these machines is mandated in some countries; however, less than 1 percent of all U.S. shops have them. A study was conducted at a U.S. dry-cleaning shop where two fifth-generation machines were used ...

    Cognitive-Behavioral Approaches to Farm Community Safety Education: A Conceptual Analysis
    Cole H
    2002/05/01 | National Institute for Occupational Safety and Health (NIOSH)
    For many years, farm health and safety education efforts have focused on the presentation of safety rules and guidelines. This method of instruction tends to ignore the contingencies that influence the actual behavior of farmers. Consequently, while most farmers understand the safety instruction messages they receive, they frequently continue to en ...

    Stimulation of macrophages has been shown to activate all three families of mitogen activated protein kinases (MAPKs). However, variable results are reported in the literature with respect to the particular kinases activated with any given stimulus. In this study, the role of activation of MAPKs was examined in the production of inflammatory mediat ...
