SECTION 2: Hazards identification

Emergency Overview: Warning Statements WARNING! MAY CAUSE SLIGHT IRRITATION. MAY BE HARMFUL IF IN CONTACT WITH OR ABSORBED THROUGH THE SKIN.

Contains

Asphalt CAS# 8052-42-4, CAS# 64742-93-4, heavy paraffinic extract, and carbon black CAS #1333-86-4. … Repeated skin contact with Rubberized asphalt adhesive in this product may result in slight irritation. Prolonged or repeated skin contact with the Unprocessed naphthenic oils contained in the Rubberized asphalt in this product may, without washing, cause an increased risk of skin cancer, liver damage, blood effects and effects on the unborn based on tests with laboratory animals. Skin cleansing studies with aromatic oils show that the toxic effects are not likely to occur in humans if good personal hygiene practices are used. … Eye contact with oil residue on hands may result in irritation. … Read and understand all Health and Safety information on the product Label and Material Safety Data Sheet before use. SYMPTOMS/EFFECTS OF OVEREXPOSURE: Acute: Excessive inhalation of fumes from hot compound can cause nausea and respiratory irritation. Chronic: Due to the aromatic and polynuclear aromatic compounds in this product, extended contact could theoretically cause cancer although specific data for this product has not been established. Skin contact, breathing of mists, fumes or vapors should be reduced to a minimum to avoid any ill effects. 2 of 7 Skin and Eye: SKIN: Prolonged or repeated contact with the Unprocessed napthenic oils in this product may produce serious toxic effects including skin cancer. Animal tests indicate that prolonged and repeated skin contact to the oils in this product may produce local skin tumors. EYE: Eye contact with oil residue may result in irritation. Ingestion: There are no known health effects due to ingestion. Due to the physical nature of this product, ingestion is unlikely. Wash hands completely before eating. Carcinogenicity Information: Heavy paraffinic extract: This product contains 5-15% of a heavy paraffinic extract which has been shown to cause cancer in laboratory animals. It is classified by IARC as a positive human carcinogen, group 1. Petroleum Asphalt: In March 1987 the International Agency for Research on Cancer (IARC) classified bitumens (such as the petroleum asphalt in this product) as a Group 3 material, “not classifiable as to its carcinogenicity to humans”. This classification was made based on inadequate evidence for the carcinogenicity of undiluted air-refined bitumens in experimental animals and inadequate evidence that bitumens alone are carcinogenic to humans. However, Asphalt does contain a small amount of Polycyclic aromatic hydrocarbons which have been shown to cause cancer and respiratory damage in animals. NIOSH recently conducted mouse skin painting studies using selected fractions of Asphalt fume condensate. Skin application of the condensate fractions resulted in skin tumors in laboratory mice. Laboratory animals exposed to repeated applications of Asphalt materials for their entire lifetime have developed skin tumors primarily at the site of application. The Asphalt material was not washed off between exposures. Intermittent or occasional skin contact with petroleum Asphalts is not expected to have serious health effects as long as good personal hygiene measures, such as those outlined in this Material Safety Data Sheet, are followed. No carcinogenic effects were observed during lifetime inhalation studies with laboratory animals; although lung damage in the test animals was observed. Findings included bronchitis, pneumonitis and abscess formation, among others, similar to problems caused by other non-specific irritants. Carbon Black: There is sufficient evidence in experimental animals for the carcinogenicity of carbon black. Carbon black is possibly carcinogenic to humans (group 2B). 3 of 7
