  • Sampling efficiencies of three personal aerosol samplers within and beyond the inhalable particle size range
    Sampling efficiencies of three personal aerosol samplers within and beyond the inhalable particle size range
    Aizenberg V ;
    Baron, Paul A.
    2001/06/02 | National Institute for Occupational Safety and Health (NIOSH)
    A Simplified Test Protocol previously developed for the performance evaluation of personal inhalable aerosol samplers was used in a specially designed compact close-loop open-section wind tunnel. Traditional wind tunnels usually cannot handle particles larger than about 100 micrometers because rapid particle sedimentation makes it virtually impossi ...

    Measurement and control of airborne microorganisms using electrostatic methods
    Baron, Paul A. ;
    Gorny R
    2001/06/02 | National Institute for Occupational Safety and Health (NIOSH)
    Most of the widely used bioaerosol sampling devices employ collection techniques that are known to reduce viability of sampled microorganisms. An electrostatic collection method, where airborne particles are electrically charged and then removed from the air by electrostatic forces, has the potential for being a "gentle" collection technique. Our t ...

  • An exposure evaluation of lead from wave soldering operations during the manufacture of circuit boards
    An exposure evaluation of lead from wave soldering operations during the manufacture of circuit boards
    King, Bradley S.
    2001/06/02 | National Institute for Occupational Safety and Health (NIOSH)
    Background: NIOSH conducted a health hazard evaluation (HHE) in response to an employee request concerning potential lead exposure at a circuit board production facility. At this facility, a 60% tin/40% lead solder is used in wave solder machines to secure electronic components to the wafer boards. In particular, two processes of concern were ident ...

    Background: In September 1999, the National Institute for Occupational Safety and Health (NIOSH) conducted a health hazard evaluation at a magazine printing company to assess exposures to resin acids during lithography printing and bindery processes. Workers reported symptoms consistent with occupational contact dermatitis, respiratory irritation, ...

  • An Evaluation of Retrofit Engineering Control Interventions to Reduce Perchloroethylene Exposures in Commercial DryCleaning Shops 2001
    An Evaluation of Retrofit Engineering Control Interventions to Reduce Perchloroethylene Exposures in Commercial Dry-Cleaning Shops [2001]
    Earnest, Gary S. ;
    Ewers, Lynda M.
    2001/06/02 | National Institute for Occupational Safety and Health (NIOSH)
    Air sampling and real-time monitoring were used to evaluate the ability of engineering controls retrofitted on two existing dry-cleaning machines to reduce worker exposures to perchloroethylene. In one dry-cleaning shop, a refrigerated condenser was installed on a machine having a water-cooled condenser to further reduce the machine air temperature ...

    Dust exposures in manual harvest of California citrus and grapes
    Lawson R ;
    Lee K
    2001/06/02 | National Institute for Occupational Safety and Health (NIOSH)
    Agricultural workers are exposed to high dust levels. Although organic compounds of particulates have been a center of focus, it has been suggested that the inorganic fraction may be just as important for agricultural exposure in relatively dry climates, such as in California. Workers performing manual harvest of citrus and grapes in California wer ...

    Control of exposures to crystalline silica in stone monument manufacturing
    Blade, Leo M. ;
    Kurimo, Robert W.
    2001/06/02 | National Institute for Occupational Safety and Health (NIOSH)
    National Institute for Occupational Safety and Health (NIOSH) researchers conducted a field survey at a small manufacturer of stone monuments (mainly cemetery markers) to characterize workers' exposures to respirable crystalline silica and to evaluate exposure control methods. These exposures result from the use of abrasive blasting for engraving a ...

  • Laboratory evaluation of ventilated shrouds for mortar grinding
    Laboratory evaluation of ventilated shrouds for mortar grinding
    Heitbrink, William A. ;
    Watkins D
    2001/06/02 | National Institute for Occupational Safety and Health (NIOSH)
    As brick buildings age, mortar deteriorates and needs to be replaced. Before replacing the mortar, the existing mortar is removed to a depth of 1.5 to 3 cm. Typically, an 11-cm diameter grinder, operated at 10,000-12,000 rpm, is used to remove mortar, causing worker exposures to respirable crystalline silica concentrations as high as 10 mg/m3. Also ...

    O'Brien, Dennis M. ;

    2001/06/02 | National Institute for Occupational Safety and Health (NIOSH)
    Most OSHA health standards require that "initial monitoring" of worker exposures be conducted to determine the frequency of further exposure monitoring, to select appropriate respiratory protection, and to determine the need for engineering controls. In 1999, the OSHA Metalworking Fluids Standards Advisory Committee (MWF-SAC) recommended that an al ...

    Boeniger, Mark F. ;
    Carreon T
    2001/06/02 | National Institute for Occupational Safety and Health (NIOSH)
    Background: Skin exposures to pesticides in agriculture are considered to be the primary route of worker contact. However, there remains a paucity of data about how to quantify and interpret sampling results. A preliminary range finding and method evaluation survey was recently performed in California in preparation for a larger study to determine ...

    2001/06/02 | Mining Publications
    Silica exposure levels in the meta/nonmetal mining industry indicate that the bag stacker is one of the highest exposure job functions for the entire industry. Malvern Minerals Company implemented two major components at their silica sand operation in an effort to lower their bag stacker's respirable dust exposure. The first component was a semi-au ...

    Miller, William E.
    2001/06/02 | National Institute for Occupational Safety and Health (NIOSH)
    A lack of information about the amount of quartz dust generated from sawing masonry makes it difficult for masonry contractors to determine if a silicosis hazard exists at their work-sites and what level of dust control or personal protection is needed. Estimating concentrations during all possible worksite conditions is unrealistic. The approach t ...

    2001/06/02 | National Institute for Occupational Safety and Health (NIOSH)
    Thousands of military personnel and tens of thousands of civilian workers perform jet fuel tank entry procedures. Before entering the confined space of a jet fuel tank, OSHA regulations (29CFR I910.146) require the internal atmosphere be tested with a calibrated, direct-reading instrument for oxygen content, flammable gases and vapors, and potentia ...

  • Lessons learned from the EPAOSHA chemical advisory skin exposure to molten 24dichlorophenol 24DCP can cause rapid death
    Lessons learned from the EPA/OSHA chemical advisory: "skin exposure to molten 2,4-dichlorophenol (2,4-DCP) can cause rapid death.
    Gillen, Matthew
    2001/06/02 | National Institute for Occupational Safety and Health (NIOSH)
    EPA and OSHA, with assistance from NIOSH, issued a Chemical Advisory on February 15, 2000, to raise awareness that the molten form of 2,4- Dichlorophenol (2,4-DCP) could cause worker fatalities after minimal skin exposure. The need for the advisory was initially triggered by notification of a worker fatality under Section 8(e) of the Toxic Substanc ...
