SECTION 2: Hazards identification

NFPA Rating Emergency Overview Under United States Regulations (29 CFR 1900.1200 - Hazard Communication Standard) the products listed above are exempt as articles under stated normal conditions of use. In Canada, these products are considered manufactured articles under the Workplace Hazardous Materials Information System (WHMIS) and are exempt. Under normal conditions of use the products listed in this MSDS are not expected to pose a physical hazard or health risk to humans. These products do not contain any form of asbestos materials. The component exposure limits and other information in this document are provided for circumstances such as heating (above 250°F), burning, cutting, sanding and/or gr inding when there is a potential for exposure to these components. If heated, this product may cause temporary irritation to the upper respiratory system. Avoid inhalation of fumes as temporary irritation may occur. Mechanical irritation may occur. Wear appropriate personal protective equipment as described in Section 8. GHS Temporary respiratory irritation may occur. Avoid breathing vapors/fumes. Contaminated work clothing should not be allowed out of the workplace. Wash thoroughly after handling. Wear protective gloves and NIOSH approved respirator if exposed to dust or if material is heated. NFPA/HMIS RATINGS: Degree of Hazard Health Fire Reactivity 0 - Minimal (Insignificant) 1 - Slight

Potential health effects

Under normal conditions of use these products are not expected to cause a physical hazard or health risk to humans. INHALATION: ACUTE (IMMEDIATE): Temporary irritation of nose and throat may occur. CHRONIC (DELAYED): This product contains crystalline silica which is listed by IARC as a suspect carcinogen. Silicosis (pulmonary fibrosis or severe lung scarring) may occur if exposed to high levels or repeated encounters with dust. Exposure to airborne particles that exceed the limits listed may cause lung cancer. This product also contains petroleum asphalt. If heated, there is limited evidence that derivatives of asphalt fumes may cause carcinogenic effects in animals. There is inadequate evidence to support that asphalt fumes alone are carcinogenic to humans. SKIN: ACUTE (IMMEDIATE): Mechanical irritation of the skin may occur. Drying of skin and dermatitis may occur following prolonged exposures. CHRONIC (DELAYED): No data available EYE: ACUTE (IMMEDIATE): Mechanical irritation of the eyes may occur. CHRONIC (DELAYED): No data available INGESTION: ACUTE (IMMEDIATE): Ingestion of this product is unlikely. CHRONIC (DELAYED): No data available MUTAGENIC EFFECTS: No information available for the product. CARCINOGENIC EFFECTS: When used under normal conditions, this product is not considered a carcinogen. This product contains petroleum asphalt. Asphalt fumes arise from hot asphalt. Asphalt fumes (CAS # 8052-42-4): In 1985/87, IARC (International Agency for Research on Cancer) concluded the following: (a) Bitumens are not classifiable as to their carcinogenicity to humans (Group 3). (b) Extracts of steam- and air-refined bitumens are possibly carcinogenic to humans (Group 2B). IARC found that evidence for carcinogenicity from animal studies was: inadequate for undiluted air-refined bitumens; limited for steam-refined and cracking residue bitumens; sufficient for extracts of steam-refined and air-refined bitumen. IARC found that human evidence for carcinogenicity of asphalt fumes was inadequate. Studies of roofers indicated an excess of cancers; however, IARC concluded that, since roofers may be exposed also to coal-tar pitches and other materials, "the excess cancer risk cannot be attributed specifically to bitumens." In 1994, a published review of 20 epidemiology studies of asphalt workers and roofers agreed with IARC, that current human evidence is inadequate for the carcinogenicity of asphalt fumes in humans. Trace amounts of polynuclear aromatic hydrocarbons (PAHs) may be present in some asphalts and can be released upon excessive heating, which results in thermal cracking of the asphalt compounds. Some of these PAHs have been identified as having the potential to induce carcinogenic and reproductive health effects. This product contains crystalline silica. IARC Monographs on Evaluation of Carcinogenic Risk of Chemicals to Humans (Monograph 68, 1997) concludes that there is sufficient evidence for the carcinogenicity of crystalline to humans, IARC (Group I). Crystalline Silica is classified as a Known Carcinogen according to the NTP. REPRODUCTIVE EFFECTS: No information available for the product.
