Marathon No. 2 Heating Oil

SECTION 2: Hazards identification

EMERGENCY OVERVIEW CAUTION! VAPORS, FUMES, OR MISTS MAY CAUSE RESPIRATORY TRACT IRRITATION MAY BE HARMFUL OR FATAL IF SWALLOWED MAY CAUSE LUNG DAMAGE OVEREXPOSURE MAY CAUSE CNS DEPRESSION MAY CAUSE CANCER BASED ON ANIMAL DATA REPEATED SKIN CONTACT HAS PRODUCED SYSTEMIC TOXICITY IN LABORATORY ANIMALS. SEE TOXICOLOGICAL INFORMATION SECTION FOR MORE INFORMATION COMBUSTIBLE LIQUID AND VAPOR VAPOR MAY CAUSE FLASH FIRE MATERIAL MAY ACCUMULATE STATIC CHARGE STABLE Inhalation: Breathing high concentrations may be harmful. May cause central nervous system depression or effects. Symptoms may include headache, excitation, euphoria, dizziness, incoordination, drowsiness, light-headedness, blurred vision, fatigue, tremors, convulsions, loss of consciousness, coma, respiratory arrest and death, depending on the concentration and duration of exposure. Overexposure to this material may cause systemic damage including target organ effects listed under

TOXICOLOGICAL INFORMATION

Ingestion: Swallowing this material may be harmful. May cause irritation of the mouth, throat and gastrointestinal tract. Symptoms may include salivation, pain, nausea, vomiting and diarrhea. Aspiration into lungs may cause chemical pneumonia and lung damage. Exposure may also cause central nervous system symptoms similar to those listed under "Inhalation" (see Inhalation section). Skin contact: Contact may cause reddening, itching and inflammation. Effects may become more serious with repeated or prolonged contact. Skin contact may cause harmful effects in other parts of the body. Eye contact: Contact may cause pain and severe reddening and inflammation of the conjunctiva. Effects may become more serious with repeated or prolonged contact. Carcinogenic Evaluation: Product information: Name IARC NTP ACGIH - OSHA - Select Carcinogens: Marathon No. 2 Heating Oil NE 68476-30-2 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 carcinogenicity to humans (Group 3A). IARC has determined that there is sufficient evidence for the carcinogenicity in experimental animals of diesel engine exhaust and extracts of diesel engine exhaust particles. IARC determined that there is only limited evidence for the carcinogenicity in humans of diesel engine exhaust. However, IARC's overall evaluation has resulted in the IARC designation of diesel engine exhaust as probably carcinogenic to humans (Group 2A) because of the presence of certain engine exhaust components. The International Agency for Research on Cancer (IARC) has also determined that there is sufficient evidence for the carcinogenicity in experimental animals of light and heavy vacuum distillates, of light and heavy catalytically cracked distillates and of cracked residues (including heavy thermocracked distillates/residues) derived from the refining of crude oil. Component Information: Name IARC NTP ACGIH - OSHA - Select Carcinogens: 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) and the Environmental Protection Agency (EPA) have determined that naphthalene is a possible human carcinogen.
