Abstract The Connecticut Department of Health Services (DHS) responded to health complaints associated with urea-formaldehyde foam insulation (UFFI) between 1977 and 1983 with free air tests. As a result of investigation of health complaints in over 500 houses, UFFI was banned in Connecticut in 1981. However, a review of recent data obtained from private laboratories indicated that formaldehyde levels in the air of homes insulated with UFFI had dropped considerably since the time of installation and prompted this current study. This study was conducted to test the supposition that formaldehyde levels had dropped significantly since the late 1970s in homes that were insulated with UFFI during that time. Formaldehyde levels were measured in 30 homes, which had been tested by the DHS in the past, and were found to have had “high” levels. In addition, ten control non-UFFI homes were tested to establish background levels. The results of this study indicate that the formaldehyde levels in the “high” UFFI houses...

Abstract The allocation of resources to protect worker's health were not based on industrial hygiene data mainly due to the unavailability of air level records and the difficulty of retrospective estimation of those levels. A method utilizing chest X-ray findings (as a biological indicator of exposure), smoking history, and job history is presented for the identification of high asbestos risk work areas (shops). The study population included 6183 shipyard workers employed in a West Coast shipyard. The prevalence rate for chest X-ray abnormalities consistent with asbestos exposure (pleural plaques) was 13.2 percent, ranging from 3.9 percent to 23.9 percent in 23 shops. Ratios of age-adjusted prevalence per 100 person-years were computed using the shop having the lowest prevalence for comparison. Workers employed in shops with prevalence ratios greater than 4.0 included the boilermakers, pipefitters, insulators, riggers, and electrician mechanics. Workers in high exposure shops who smoked were found to have...

Abstract The high degree of potential toxicity associated with the use of arsenic and phosphorus compounds requires special safety considerations during the design and operation of chemical vapor deposition (CVD) reactors used for the production of photonic materials. As the use of photonic materials becomes more widespread with the growth of the optical communication industry, CVD reactors used for the growth of photonic materials (e.g., indium-gallium-arsenide-phosphide) must include sophisticated safety and environmental control systems. The control systems used at AT&T-Microelectronics are described in this article. The exhaust system is designed to prevent exposure to any of the toxic source chemicals used in the reactor. The vent scrubbing system traps arsenic-contaminated reaction products before they reach the outside environment. Safety control logic takes control of the reactor from the resident microprocessor during maintenance and emergency conditions to ensure that safe operating conditions a...

Abstract The recently developed passive colorimetric dosimeter tubes potentially offer great advantages of compactness, convenience, and simplicity in environmental evaluation of a wide variety of toxic gases and vapors. These devices do not require pumps but operate on diffusion principles to produce stain lengths proportional to time-weighted average concentrations that can be read immediately at the site. The purpose of this study was to evaluate the performance of colorimetric passive dosimeter tubes for carbon monoxide under dry and humid conditions. A flow dilution system using 2.58 percent carbon monoxide in air from a cylinder was used to provide 25, 50, 100, and 400 ppm of carbon monoxide at relative humidities of 20 percent and 82 percent and at a temperature of 26°C. Tubes from three manufacturers (Gastec/Sensidyne, Draeger, and MSA) were exposed for periods up to six hours, and the stain lengths were read (independently) by two observers at quarter- and half-hour intervals, depending upon the ...
