    Tree Climber Crushed by Falling Tree Section
    New Jersey Fatality Assessment & Control Evaluation Project (NJ FACE)  ...
    2002/02/26 | Fatality Assessment and Control Evaluation Reports (FACE)
    On June 4, 2001, a 24-year-old tree trimmer was killed when the tree to which he was secured fractured beneath him and fell to the ground. Since he was tied to the tree with his lanyard, he fell with the broken section, and was crushed under it. NJ FACE staff concluded that, to prevent similar incidents, the following safety guidelines should be fo ...

    2002/02/26 | Fatality Assessment and Control Evaluation Reports (FACE)
    A 43-year-old city employee (victim) died after he was pinned between the hopper and the suction hose of a street sweeper. The sweeper design, known as a cross wind design uses a loop of air which results in less dust being returned to the environment. A large flexible suction hose connects one end of the sweeper's pickup head to the collection hop ...

    2002/02/25 | Mining Publications
    A NIOSH study on occupational deaths between 1980 and 1989 indicated that in the United States, mining had the highest average annual fatality rate (31.9 per 100,000 workers) of any other major industry. Since "lack of training" was often cited as the primary cause of accidents, NIOSH has been investigating new methods for effective training. One s ...

    2002/02/25 | Mining Publications
    A deep longwall coal mine was instrumented with a three-dimensional microseismic system in order to help determine the exact strata mechanics associated with the rock failure, redistribution of stress and the associated gob formation from the longwall. Overall, 5,000 well calibrated seismic events were recorded during the mining of the panel. Analy ...
