Marathon Slow Cure Asphalt

SECTION 2: Hazards identification

EMERGENCY OVERVIEW DANGER! HOT PRODUCT CAN CAUSE BURNS TO SKIN CONTAINS HYDROGEN SULFIDE GAS. MAY BE FATAL IF INHALED GAS MAY EVOLVE FROM THIS MATERIAL AND ACCUMULATE IN CONFINED SPACES. FUMES FROM HOT PRODUCT CAN CAUSE IRRITATION TO THE EYES, SKIN AND RESPIRATORY SYSTEM WATER CONTACT CAN CAUSE VIOLENT ERUPTION OF HOT ASPHALT SUSPECT CANCER HAZARD POTENTIAL REPRODUCTIVE HAZARD SEE TOXICOLOGICAL INFORMATION SECTION FOR MORE INFORMATION COMBUSTIBLE LIQUID STABLE Inhalation: May release hydrogen sulfide gas which is highly toxic. Hydrogen sulfide can cause respiratory paralysis and death, depending on the concentration and duration of exposure. Do not rely on ability to smell vapors, since loss of smell rapidly occurs. Effects of overexposure include irritation of the nose and throat, nausea, vomiting, diarrhea, abdominal pain and signs of nervous system depression (e.g. headache, drowsiness, dizziness, loss of coordination and fatigue), irregular heartbeats, pulmonary edema, weakness and convulsions. Fumes or vapors from the heated material may be irritating to the respiratory tract. Overexposure to this material may cause systemic damage including target organ effects listed under

TOXICOLOGICAL INFORMATION

Ingestion: Contact with hot material may cause thermal burns. If swallowed at ambient temperature no significant adverse effects are expected. May cause irritation of the mouth, throat and gastrointestinal tract. Ingestion of large amounts may cause gastrointestinal blockage. Skin contact: Contact with hot material may cause thermal burns. Contact may cause reddening, itching and inflammation. Skin contact may cause harmful effects in other parts of the body. Eye contact: Exposure to hot material can cause thermal burns. Vapors may cause eye irritation and sensitivity to light. Effects may become more serious with repeated or prolonged contact. Carcinogenic Evaluation: Product information: Name IARC NTP ACGIH - OSHA - Select Carcinogens: Marathon Slow Cure Asphalt NE Mixture Notes: The International Agency for Research on Cancer (IARC) has determined that there is sufficient evidence for the carcinogenicity of extracts of steam-refined bitumens (asphalts), air-refined bitumens and pooled mixtures of steam- and air-refined bitumens in experimental animals. IARC has determined that there is inadequate evidence that bitumens alone are carcinogenic to humans. Component Information: Name IARC NTP ACGIH - OSHA - Select Carcinogens: Asphalt Supplement 7 [1987], Reasonably Anticipated To A4 - Not Classifiable as a Present 8052-42-4 Monograph 35 [1985] Be A Human Carcinogen Human Carcinogen (fume, (extracts of steam-refined coal tar-free) and air-refined) Naphthalene Monograph 82 [2002] Reasonably Anticipated To A4 - Not Classifiable as a Present 91-20-3 Be A Human Carcinogen Human Carcinogen male rat-clear evidence; female rat-clear evidence; male mice-no evidence; female mice-some evidence Notes: The International Agency for Research on Cancer (IARC) has determined that there is inadequate evidence for the carcinogenicity of diesel fuel/fuel oil in humans. IARC determined that there was limited evidence for the carcinogenicity of marine diesel fuel in animals. Distillate (light) diesel fuels were not classifiable as to their carcinogeniicty to humans (Group 3A) The International Agency for Research on Cancer (IARC) has determined that there is sufficient evidence for the carcinogenicity of untreated vacuum distillates, acid- treated oils, and aromatic oils, including extracts from solvent treatment of distillates and the high boiling fraction of catalytically cracked oils in animals. The International Agency for Research on Cancer (IARC) has determined that there is sufficient evidence for the carcinogenicity of residual (heavy) fuel oil in animals. The International Agency for Research on Cancer (IARC) and the Environmental Protection Agency (EPA) have determined that naphthalene is a possible human carcinogen.
