  • Report of Investigations 9653 Economics of Safety at Surface Mine Spoil Piles
    Report of Investigations 9653: Economics of Safety at Surface Mine Spoil Piles
    Camm, Thomas W.
    2000/07/01 | NIOSH Numbered Publications
    This study was done to evaluate the costs of various dumping operations at waste and spoil piles. It has been the theorized that accidents associated with dumping operations might be reduced by short-dumping rather than edge-dumping, but many operators have been reluctant to use short-dumping because they believe it is not as cost effective as edge ...

  • Occupational Injury in Migrant Hispanic FarmWorker Families
    Occupational Injury in Migrant Hispanic Farm-Worker Families
    Beaumont, James J. ;
    Carroll DJ
    2000/06/30 | Grant Final Reports
    The agriculture industry is among the most hazardous industries in the United States. California hosts approximately 700,000 hired farm workers, who perform the majority of field production labor. In spite of the large size of this population and its economic importance for California, few data are available addressing its injury risk. We conducted ...

    Physical Versus Biological Hydrocarbon Removal During Air Sparging and Soil Vapor Extraction
    Aelion CM ;
    Kirtland BC
    2000/06/28 | National Institute for Occupational Safety and Health (NIOSH)
    Although physical removal of contaminants may account for the majority of mass of petroleum hydrocarbons (PH) removed using air sparging and soil vapor extraction (AS/SVE), biological processes contribute to mass removal both during system operation and during system shutdown. Biodegradation rates are difficult to measure during active AS/SVE due t ...

    Using Existing Workers’ Compensation Medical Claims Data to Improve Workplace Safety
    Peele PB ;
    Stockman CK
    2000/06/25 | National Institute for Occupational Safety and Health (NIOSH)
    Research Objective: When medical claims for injured workers are processed, a claims level workers' compensation database is created. Few, if any, employers currently take advantage of the existence of these data. Many would like to tap into these already existing databases to monitor the safety of their workplace, but lack the analytical techniques ...

    2000/06/25 | National Institute for Occupational Safety and Health (NIOSH)
    RESEARCH OBJECTIVE: Prior investigations of how primary care physicians (PCP's) address work status of their patients have focused on disability claims, and have not addressed the larger scope of work-related issues that arise in primary care practice. This study was conducted to evaluate the extent of these practices and opportunities for improvem ...

    2000/06/22 | National Institute for Occupational Safety and Health (NIOSH)
    Malignant mesothelioma is known to be associated with asbestos exposure. However, the mechanism of mesothelial carcinogenesis in relation to the activation of proto-oncogenes or inactivation of tumor suppressor genes remains unclear. In this study, the PCR-Primer Introduced Restriction Site (PCR-PIRS) assay was employed to examine mutations in the ...

  • Occupational Fatalities Associated with 24Dichlorophenol 24DCP Exposure 19801998
    Occupational Fatalities Associated with 2,4-Dichlorophenol (2,4-DCP) Exposure, 1980–1998
    National Institute for Occupational Safety and Health
    2000/06/16 | Weekly Report: Morbidity and Mortality Weekly Report (MMWR)
    2,4-Dichlorophenol (2,4-DCP) is a feedstock chemical primarily used to produce the herbicide 2,4-dichloropheoxyacetic acid (2,4-D). In October 1998, the U.S. Environmental Protection Agency (EPA) was notified of the death of a worker acutely exposed to 2,4-DCP. Follow-up investigation by EPA, the Occupational Safety and Health Administration (OSHA) ...

    Thalidomide has been shown to have antiinflammatory and, more recently, immunomodulating properties, which are beneficial for the treatment of an ever-increasing list of immune related diseases. Although considerable knowledge regarding thalidomide's antiinflammatory properties has been acquired, relatively little is known about its immunomodulatin ...
