Asphalt Fume Exposures During the Application of Hot Asphalt to Roofs

This document represents a collaborative effort of the National Institute for Occupational Safety and Health (NIOSH), the National Roofing Contractors Association (NRCA), the Asphalt Roofing Manufacturers Association (ARMA), the Asphalt Institute (AI), and the United Union of Roofers, Waterproofers, and Allied Workers (UURWAW) to reduce worker exposures to asphalt fumes during the application of hot asphalt to roofs. The document describes the application of hot asphalt to roofs, identifies steps in the process that may involve worker exposure to asphalt fumes, and identifies current engineering controls and work practices used to reduce exposures.
