Self-contained breathing apparatus. SECTION 9 PHYSICAL AND CHEMICAL PROPERTIES Appearance& Odor: Black viscous semi-solid.Asphalt or rotten egg odor. Substance Chemical Family: Petroleum Hydrocarbon Flash Point 560 IF [Closed Cup] Specific Gravity 1.018 @ 77 OF Stability Stable Viscosity 4100 poise @ 140 OF SECTION 10 REACTIVITY AND STABILITY Stability: Material is stable under normal conditions. Materials to Avoid: Do not allow molten material to contact water or liquids as this can cause violent eruptions, splatter hot material, or ignite flammable material. Avoid contact with strong oxidizing agents. Hazardous Decomposition Products: Thermal decomposition products are highly dependent on combustion conditions. A complex mixture of airborne solids, liquids and gases will evolve when this material undergoes pyrolysis or combustion. Carbon Monoxide, Carbon Dioxide, Hydrogen Sulfide, Miscellaneous Organic Material, Simple Hydrocarbons and other unidentified organic compounds may be formed upon combustion. SECTION 11 TOXICOLOGICAL INFORMATION Carcinogenicity Classification Chemical Name NTP IARC ACGIH OSHA Asphalt No Not Classifiable (3) No No Heavy Naphthenic Petroleum Distillates No Carcinogen (1) No No Carcinogenicity Certain asphalt fume condensates have been shown to cause tumors when repeatedly painted on the skin of laboratory mice.The relevance of these data to humans exposd to the fume itself is unknown.The International Agency for Research on Cancer has classified untreated mineral oils as Carcinogenic to Humans(Group 1). The component used in this product(Heavy Naphthenic Petroleum Distillate) meets the criteria for such an oil.A similar petroleum fraction also induced skin tumors in male mice in a long-term skin painting study. Epidemiology There is no evidence that human exposure to bitumen or its fumes in manufacturing processes or in road use results in any cancer risk.While there is some evidence of an increased risk of lung cancer among roofers, building insulators and mastic asphalt workers,concurrent or previous exposure to coal tar products has also taken place and may therefore have been responsible. Genotoxicity Two samples of vaccum residuum were found to be non-genotoxic(no genetic damage)in a live rat study and weakly genotoxic when metabolically activated in an in vitro(test tube)assay. Lungs Mice exposed to laboratory-generated asphalt fume for up to 21 months developed bronchitis along with inflammation and other signs of lung injury. SECTION 12 ECOLOGICAL INFORMATION Environmental Impact Summary: There is no ecological data available for this product.
