    2001/08/01 | Fatality Assessment and Control Evaluation Reports (FACE)
    During February 1999, a 62-year-old self-employed tree trimmer died after falling 35 feet from the bucket of a boom truck and landing on the frozen ground. The 2-piece hydraulic lift arm was in an extended vertical position when a hydraulic safety valve on the main hydraulic cylinder snapped off, causing the lift arm to collapse and the bucket to i ...

    A machine malfunction, a momentary lapse in concentration, a misjudgment of the weight of the box. Every day, about 450 Minnesotans are hurt at work or become ill from an occupational-related cause, according to recent Minnesota Department of Labor and Industry (MNDLl)-figures. Workplace injuries are expensive. Compensation amounted to an estimated ...

    Many of the job processes being performed today in ship construction, repair and recycling yards do not differ significantly from those same processes as performed fifty years ago. The complexity of vessels may have increased dramatically in the past fifty years but many of the job processes have not kept pace with changes in technology. Due in par ...

    Kuempel, Eileen D.
    2001/08/01 | National Institute for Occupational Safety and Health (NIOSH)
    The objective of this study is to investigate the sources of variability and uncertainty in a previously developed human lung dosimetry model. That three-compartment model describes the retention and clearance kinetics of respirable particles in the gas-exchange region of the lungs. It was calibrated using exposure histories and lung dust burden da ...

    2001/08/01 | National Institute for Occupational Safety and Health (NIOSH)
    The timing of a stressful event with respect to antigen exposure affects the development of the immune response. We have reported that restraint applied to a naive mouse prior to sensitization (day 1) decreased chemical-induced changes in ear swelling and lymphocytosis and restraint applied during sensitization (days 1 and 2) or prior to challenge ...

    2001/08/01 | National Institute for Occupational Safety and Health (NIOSH)
    There are at least three mechanisms by which alveolar macrophages play a critical role in protecting the lung from bacterial or viral infections: production of inflammatory cytokines that recruit and activate lung phagocytes, production of antimicrobial reactive oxidant species, and production of interferon (an antiviral agent). In this article we ...

    2001/08/01 | National Institute for Occupational Safety and Health (NIOSH)
    Biomechanical stability of the lumbar spine is an important factor in the etiology and control of low-back disorders. A principle component of biomechanical stability is the musculoskeletal stiffening generated by preparatory muscle coactivation. The goal of this investigation was to quantify preparatory behavior, evaluating trunk muscle activity i ...
