  • Counting Coin and Paper Currency Were Reported Health Problems Related to the Work Environment
    Counting Coin and Paper Currency: Were Reported Health Problems Related to the Work Environment?
    Delaney, Lisa J. ;
    Kiefer, Max
    2002/06/01 | National Institute for Occupational Safety and Health (NIOSH)
    Measured exposures to nickel, copper, and zinc during currency counting activities were below applicable exposure criteria, and did not show an inhalation hazard for the sampled employees. The surface sampling results indicate that additional cleaning in the coin-counting room is warranted to make sure that metal dust does not accumulate. Exposure ...

    2002/06/01 | National Institute for Occupational Safety and Health (NIOSH)
    Occupational exposure is a known risk for chronic obstructive lung disease (COPD). The contribution of employment in industries to COPD was established for the U.S. population using the third National Health Nutrition Examination Survey (NHANES III) data. Race/ethnic- and sex-specific weighted prevalence, prevalence odds ratios and attributable fra ...

    Deddens J ;
    Jones, Richard
    2002/06/01 | National Institute for Occupational Safety and Health (NIOSH)
    Employees who are monitored for lead exposure must routinely have a venipuncture sample taken, which is both uncomfortable and normally collects more blood than needed for analysis. Capillary sampling is less invasive but introduces the possibility of surface contamination. The objective of this study was to compare venous and capillary (earlobe) b ...

    Airborne Microbial Ecology in an Underground Coal Mine
    Cocalis, Joseph C. ;
    Martin, Jennifer E.
    2002/06/01 | National Institute for Occupational Safety and Health (NIOSH)
    Underground coal mines may be an environment with exposures to airborne fungi and bacteria. The environments are often water-laden due to dust-suppression systems, ground water seepage and/or high relative humidities. We investigated the airborne microbial ecology at the longwall face of an underground coal mine. Samples for bacteria and fungi in a ...

    2002/06/01 | National Institute for Occupational Safety and Health (NIOSH)
    New 42 CFR 84 electrostatic non-powered, air-purifying respirator filters, approved for use in conjunction with organic vapor cartridges, were tested for filter efficiency degradation resulting from organic vapor exposures. N-, R-, and P-series filters were exposed to saturated organic vapors for varying amounts of time to determine a worst-case de ...

    Statistical Analysis of the Benzene Soluble Fraction in Field Blanks Used in NIOSH Method 5042
    Olsen, Larry D. ;
    Shulman S
    2002/06/01 | National Institute for Occupational Safety and Health (NIOSH)
    During the development of NIOSH Method 5042, an anomaly was noticed in the field blank data. Three of 60 field blanks had a higher than expected benzene soluble fraction. Since this event may occur with field samples, these results were not excluded when the data were evaluated. Although these events were observed with syringe-type clarification un ...

    2002/06/01 | National Institute for Occupational Safety and Health (NIOSH)
    Although the literature on the relationship between work and the family has grown substantially over the past 20 years, it is based primarily on studies conducted with white, middle-class workers. Thus, it is questionable whether findings can be generalized to nonwhite populations. This paper addresses the situation by utilizing a diverse sample. S ...

    Chemical protective clothing and gloves used for adequate protection are usually too expensive to be considered disposable. Decontamination is therefore essential before protective clothing is reused. The objective of (TWA) permissible exposure limit (PEL) for C1O2 of 0.1 ppm and a short term (15 minute) exposure limit (STEL) of 0.3 ppm. In order t ...

    FIock refers to short fibers which are applied to a surface to produce a velvet-like finish. We have previously reported on dust levels and aerosol characteristics in a plant where nylon flock fibers are produced and applied to fabric backing material. High dust levels were recorded and microscopic analysis was used to identify a variety of particl ...

    Christiani, David C.
    2002/06/01 | National Institute for Occupational Safety and Health (NIOSH)
    In a 2-year longitudinal study of boilermaker construction workers, we found a significant association between working at oil-fired, coal-fired, and gas-fired industries during the past year and reduced lung function. In the present study, we investigated whether chronic bronchitis, asthma, or baseline methacholine airway responsiveness can explain ...

    Miller DB ;

    2002/06/01 | National Institute for Occupational Safety and Health (NIOSH)
    Disruptions in homeostasis (ie, stress) place demands on the body that are met by the activation of 2 systems, the hypothalamic-pituitary-adrenal (HPA) axis and the sympathetic nervous system (SNS). Stressor-induced activation of the HPA axis and the SNS results in a series of neural and endocrine adaptations known as the "stress response" or "stre ...

    The purpose of this study was to quantify, in real-time, variations in muscle performance during 150 stretch-shortening contractions. The analysis of the dynamic muscle response was used to predict the onset of muscle injury. The isometric performance recovery and tissue response after exposure levels of 30 and 70 repetitions, respectively, indicat ...
