Health Hazard Evaluation Report, HETA-83-210-1887, Roofing Construction, Houston, Texas

摘要

An evaluation was made of possible hazardous working conditions at roofing sites in Houston, Texas. Roofing systems evaluated included: tear off and application of a coal tar pitch system; tear off and application of a petroleum asphalt system; and application of a single ply modified asphalt system (Koppers). Personal exposures to hazardous materials were highest in the coal tar pitch operation with 85 hydrocarbons (PNAs). Medical evaluation indicated eye and skin irritation and lesions in workers. The author concludes that workers were exposed to potentially hazardous concentrations of coal tar pitch and petroleum asphalt roofing sites. The author recommends specific measures to reduce exposures, including better personal hygiene, use of personal protective equipment, staying upwind of dust and fumes, wetting roofs before tear off, use of sunscreens and avoiding work during the hours of greatest sun intensity.
