In the course of this project, asphalt kegs were not broken into smaller pieces prior to loading into an asphalt kettle. To cause the larger pieces of asphalt to melt in a timely manner, the kettle operator increased the temperature of the kettle, which overheated the asphalt and increased the risk of a kettle fire. To reduce the risk of hot asphalt fires and injuries, identify trained and experienced installers who know how to properly handle and install hot asphalt. Alternative roof designs that use cold process materials may also be considered.
“Fire is only one of the risks associated with hot asphalt. Ensuring the asphalt is installed at the correct temperature is critical to the long-term roof performance. Asphalt that is not installed at the right temperature may result in poor adhesion within the inter-ply felts, potentially causing blisters and premature roof failure," according to Tom Irvine, RRC and Senior Consultant with Benchmark, Inc.
