  • Occupational Slip Trip and FallRelated Injuries Can the Contribution of Slipperiness Be Isolated
    Occupational Slip, Trip, and Fall-Related Injuries – Can the Contribution of Slipperiness Be Isolated?
    Collins JW ;
    Courtney TK
    2001/10/20 | National Institute for Occupational Safety and Health (NIOSH)
    To determine if the contribution of slipperiness to occupational slip, trip and fall (STF)-related injuries could be isolated from injury surveillance systems in the USA, the UK and Sweden, six governmental systems and one industrial system were consulted. The systems varied in their capture approaches and the degree of documentation of exposure to ...

    2001/10/20 | National Institute for Occupational Safety and Health (NIOSH)
    Exposure to tetrachloroethylene (TCE) occurs in a number of occupational settings such as during dry-cleaning and metal degreasing. Phenotypic and genotypic changes during carcinogenesis may be demonstrated by the cell transformation and tumorigenesis assays and by molecular analyses. To study the carcinogenic potential of TCE, BALB/c-3T3 cells wer ...

    On July 30, 2001, a 47-year-old male tree feller (the victim) died of injuries sustained when he was pinned to the ground by the tree he was felling. The victim was felling trees on terrain with a 40% slope. He was in the process of felling a poplar, which was approximately 20 inches in diameter at breast height (DBH) and 100 feet tall. It was loca ...

    Pulmonary waveform generators consisting of motor driven piston pumps are commonly used to test respiratory function equipment. Gas compression within these generators can produce significant distortion of the output flow-time profile when testing peak expiratory flow (PEF) meters. The waveform generator with load (PEF meter connected at the genera ...

    Frazer D ;
    Friend KA
    2001/10/04 | National Institute for Occupational Safety and Health (NIOSH)
    When an excised lung is slowly ventilated, not all gas entering the lung during inflation can be removed during the following lung deflation. In order to develop a realistic model of the gas trapping process, it is important to determine the mechanical characteristics of the region of the lung where gas trapping takes place. In this study, excised ...
