Health Hazard Evaluation Determination Report No. 75-102-304, Sellers and Marquis Roofing Company, A. J. Shirk Roofing Company, Western Roofing Company, and the Quality Roofing Company; A Joint Venture, Kansas City, Missouri

摘要

Exposures to toxic chemicals were investigated for the Sellers and Marquis, A. J. Shirk, Western, and Quality Roofing Companies, Kansas City, MO, during joint installation of roofing for a 46 acre warehouse in Lenexa, KS. The medical and environmental survey was conducted on September 4 and 18, 1975. Asphalt and coal tar pitch were suspected causes of worker reports of skin and eye irritations. Personal and area air samples and total particulates samples were collected and analyzed for particulate polycyclic organic matter (PPOM), coal tar pitch volatiles (CTPV), polycyclic aromatic hydrocarbons (PAH), benzo(a)pyrene (BaP), and benzo(e)pyrene (BeP). All asphalt and duct samples were below 2 milligrams per cubic meter (mg/CuM) and under the ACGTH recommended threshold limit value (TLV) of 5 mg/CuM for asphalt fumes and 10 mg/CuM for fibrous glass dust. Six workers out of 26 were exposed to potentially toxic concentrations of PPOM which exceeded the TLV of 0.20 mg/CuM. Exposure concentrations for 3 of 7 workers exceeded the standard. BaP and BeP were not detected. A total of 69 and 50% of the examined roofers reported skin photosensitivity and conjunctival symptoms. Examinations verified moderate or mild conjunctivitis, photosensitization, and generalized erythema among the workers.
