    2001/11/01 | National Institute for Occupational Safety and Health (NIOSH)
    Studies have suggested that occupational disease and injury are under-recognized by clinicians. To estimate the frequency of occupational factors in disease and injury, 108 patients in a general (not occupational) health care facility were interviewed about the frequency and types of workplace-health interactions. Thirty-nine percent reported possi ...

    2001/11/01 | Mining Publications
    Falls of ground continue to be one of the most serious causes of injury to U.S. miners. Of the 256 fatal injuries that occurred in mining between 1996 and 1998, 59 (23%) were caused by falls of round (Table 23.1). Falls of ground affect some sectors of the mining industry more severely than others. For instance, nearly 40% of the 98 coal mine fatal ...

    Cell growth arrest is an important mechanism in maintaining genomic stability and integrity in response to environmental stress. Using human lung epithelial cell line, A649, the present study investigates the role of reactive oxygen species (R08) and ERK and p38 protein kinase in vanadate-induced cell growth arrest. Exposure of the cells to vanadat ...

    Lightning Propagation Through the Earth and Its Potential for Methane Ignitions in Abandoned Areas of Underground Coal Mines
    Fisher, Thomas J. ;
    Novak T
    2001/11/01 | Mining Publications
    Strong circumstantial evidence suggests that lightning has initiated methane explosions in abandoned and sealed areas of underground coal mines. The Mine Safety and Health Administration (MSHA) investigated several of these occurrences within recent years. The investigated explosions occurred at significant depths, ranging from 500 ft to 1200 ft. D ...

    The Use of Reverse Diffusion to Validate the Performance of Diffusive Samplers
    Schweder M ;
    Underhill D
    2001/11/01 | National Institute for Occupational Safety and Health (NIOSH)
    A number of different protocols have been put forth for measuring reverse diffusion from diffusive samplers. The basic concept is that reverse diffusion tests, depending as they do on basic laws of mass transfer, are not independent of one another, but may give general information about the limits to the possible change that can occur if the condit ...

    Hexamethylene diisocyanate (HDI) is used widely to manufacture polyurethanes for paints and coatings. It is an irritant and a chemical asthmagen. The U.S. Occupational Safety and Health Administration time-weighted average permissible exposure limit is 5 ppb and the ceiling limit is 20 ppb. We sought to develop a sensitive and specific immuno-bioas ...
