Health hazard determination report: HHE-79-106-635, Beth Israel Hospital Laboratory, Denver, Colorado.
NIOSH 1979 Dec; :1-6
Ethanol (64175), formaldehyde (50000), toluene (108883), and xylene (1330207) exposures were measured at the Beth Israel Hospital Laboratory (SIC-8062), Denver, Colorado, on June 14, 1979, in response to a request from hospital management on behalf of 13 employees. All workers were monitored for the particular solvent they worked with and were interviewed to determine if overexposure symptoms were present. Eleven breathing zone and general air samples were collected on organic vapor charcoal sampling tubes using vacuum pumps. Ethanol and formaldehyde were below the laboratory limit of detection in all samples, and below the 1,900 milligrams per cubic meter (mg/m3) threshold limit value and 1.2 mg/m3 OSHA standard, respectively. The highest concentrations of toluene and xylene reached 12 and 33mg/m3, respectively. The respective OSHA standards were 375 and 435mg/m3. No symptoms related to overexposure were reported. The author concludes that employees were not overexposed to any chemicals and recommends that all new employees be briefed on the toxicity of ethanol, formaldehyde, toluene, and xylene.
