    An Evaluation of an Engineering Control to Prevent Carbon Monoxide Poisonings of Individuals on Houseboats
    Dunn, Kevin H. ;
    Earnest, Gary S.
    2001/03/01 | Engineering and Physical Hazards Survey Reports
    During the period of 1990 to 2000, 111 carbon monoxide (CO) poisoning cases occurred on Lake Powell near the border of Arizona and Utah. Seventy-four of the poisonings occurred on houseboats, and 64 of these poisonings were attributable to generator exhaust alone. Seven of the 74 houseboat-related CO poisonings resulted in death. Many of the CO poi ...

    Karol MH ;
    Lange RW
    2001/03/01 | National Institute for Occupational Safety and Health (NIOSH)
    Diisocyanates are the most frequent cause of chemically-induced occupational asthma. Chemically-induced asthma differs from occupational asthma caused by high molecular weight allergens, in that specific antibodies are rarely found in the sera of patients with chemically-induced asthma. To investigate the role of anitbodies in the pathogenesis of t ...

    2001/03/01 | National Institute for Occupational Safety and Health (NIOSH)
    Metal working fluids (MWFs) are widely used in industry for metal cutting, drillings, shaping, lubricating, and milling. Many occupational health concerns have arisen for workers exposed to MWFs. It has been reported earlier that occupational exposure to MWFs causes allergic and irritant contact dermatitis. Previously, we have shown that dermal exp ...

    2001/03/01 | National Institute for Occupational Safety and Health (NIOSH)
    Phenolic compounds are known to cause skin rashes, burns and ulceration, dermal inflammation and necrosis, irritant and allergic contact dermatitis, eczematous "black-spot" dermatitis, leukoderma and cancer promotion. In many cases, the mechanisms underlying these toxic effects are unknown. Enzymatic oxidation of phenols is an effective metabolic p ...

  • A Chromatographic Method for Determination of 3Amino5Mercapto12 4Triazole in Biological Fluids
    A Chromatographic Method for Determination of 3-Amino-5-Mercapto-1,2, 4-Triazole in Biological Fluids
    Depree GJ ;
    Siegel, Paul D.
    2001/03/01 | National Institute for Occupational Safety and Health (NIOSH)
    The chemical, 3-amino-5-mercapto-1,2,4-triazole (AMT) is used in the manufacture of the pesticide, flumetsulam. Analysis of AMT in biological fluids requires a sensitive and selective analytical method. Direct quantitation of AMT using HPLC coupled with UV detection was found to be unsuitable due to poor sensitivity and retention of AMT on reverse ...

    Technology News 487: Sweeping Compound Application Reduces Dust from Soiled Floors Within Enclosed Operator Cabs
    National Institute for Occupational Safety and Health
    2001/03/01 | Mining Publications
    Enclosed operator cabs are widely used on mobile excavation equipment in the mining and construction industries. They protect the operator from bad weather, noise, and airborne dusts. The inside cab environment usually must be kept at very low dust concentrations because of quartz dust generated from the excavation of silica-bearing rock. For cabs ...

    2001/03/01 | Mining Publications
    Many types of heavy equipment are used in mining, construction, and agriculture. Most have enclosed cabs to protect the equipment operator from excessive dust and noise exposure. When the equipment is new, controls are normally implemented into the cab to keep these exposures at acceptable levels. However, as this equipment becomes older, many comp ...

    2001/03/01 | Mining Publications
    Ore passes are underground conduits for the gravity transport of broken ore, waste rock, and fill from one level of a mine to a lower level. Inclination of ore passes typically ranges from vertical to 30 degrees (Pariseau 1966), and cross sections may be square, rectangular, or circular. Historically, cross-sectional areas were generally less than ...
