    Reducing Respirator Fit-Test Errors: A Multi-Donning Approach
    Campbell, David D. ;
    Coffey, Christopher C.
    2002/06/01 | Mining Publications
    Because fit-testing is the only assurance that an individual has an adequately protecting respirator, the error rates of current fit-tests are of concern. Previous laboratory studies with filtering-facepiece respirators have found significant fit-test error rates. The alpha error (failing a respirator/subject combination that should pass) ranged fr ...

    2002/06/01 | National Institute for Occupational Safety and Health (NIOSH)
    To aid in the process of characterizing corn dust exposures on farms and in elevators in northeastern Colorado, several parameters were examined. Total dust and respirable dust samples were collected and evaluated. Potentially dangerous dust components evaluated were respirable silica, endotoxin, and mycotoxin levels. Many of the total dust samples ...

    Henneberger, Paul K.
    2002/06/01 | National Institute for Occupational Safety and Health (NIOSH)
    A survey of beryllium contamination on workers' hands and inside their personal vehicles at a machine shop where workers had developed chronic beryllium disease (CBD) showed that they were likely to have carried beryllium on their bodies and clothes into their homes. These take-home beryllium exposures could potentially not only increase the worker ...

    2002/06/01 | National Institute for Occupational Safety and Health (NIOSH)
    Surface and skin decontamination and use of nitrile gloves may be important interventional measures in reducing isocyanate skin exposures in auto body shops, but their effectiveness needs to be evaluated before recommendation for larger scale interventions is made. This pilot study was designed to assess such effectiveness. Three auto body shops wi ...
