Roofing Tar and Hot Asphalt Application (Coal Tar Pitch Volatiles) — household safety profile
Severe riskHot-applied roofing materials: coal tar pitch (built-up roofing) and oxidized asphalt (modified bitumen).
What is this product?
Hot-applied roofing materials: coal tar pitch (built-up roofing) and oxidized asphalt (modified bitumen). Coal tar pitch volatiles (CTPV) are IARC Group 1 carcinogens — roofers have elevated lung and skin cancer rates. Asphalt fumes are less carcinogenic but still irritating. Kettle/tanker heating to 200-300C generates maximum fume exposure. NIOSH: roofers are among the most PAH-exposed occupational groups.
