Asphalt Saturated Roll Roofing Products

Appearance/Odor

Dark mat with an asphalt odor Under normal conditions of use, this product is not expected to create any unusual emergency hazards. Inhalation of excessive amounts of dust from the product may cause temporary upper respiratory irritation and/or congestion—remove affected individuals to fresh air. NOTE: Hydrogen sulfide (H2S), an extremely toxic gas, may be emitted from heated asphalt and may accumulate in storage tanks and other confined spaces. At low concentrations, H2S is irritating to the eyes, nose and throat, and at high concentrations (>500ppm) can cause rapid unconsciousness and death. The odor of H2S cannot be used as an indicator of exposure, because the gas causes rapid olfactory fatigue, which deadens the sense of smell. Use this product only under well-ventilated working conditions. Skin irritation may be treated by gently washing affected area with soap and warm water. Flushing eyes with large amounts of water may treat eye irritation. If irritation persists, contact a physician. In the event of fire, follow normal fire fighting procedures to prevent inhalation of smoke and gases. 1
