Although asphalt skin painting studies on animals have shown tumor development, no association between human exposure to asphalt and cancer has been scientifically established. Thermal decomposition products are highly dependent on the combustion conditions. A complex mixture of airborne solids, liquid, particulates and gases will evolve when this material undergoes pyrolysis or combustion. Carbon monoxide and other unidentified organic and inorganic compounds may be formed upon combustion. May contain hydrogen sulfide, a toxic gas.
Material Is a mechanical irritant for skin, eyes and upper respiratory system.
Crystalline silica can cause silicosis, a noncancerous lung disease caused by excessive exposure to crystalline silica. Inhalation of dust or fibers form this product is not likely to occur due to intended use and the product form. When combining the results of three international mortality studies of fiber glass manufacturing workers, no statistically increased risks for malignant respiratory disease are found. Use adequate ventilation to keep the airborne concentrations of this material below the exposure standard. Snug fitting long pants and long sleeves and boots are recommended to prevent contact with hot material.
