4. FIRST AID MEASURES
Inhalation: If affected, move person to fresh air. If breathing is difficult, administer oxygen. If not
breathing or if no heartbeat, give artificial respiration or cardiopulmonary
resuscitation (CPR). Immediately call a physician. If symptoms or irritation occur with
any exposure, call a physician.
Skin contact: Wash with soap and large amounts of water. If symptoms or irritation occur, call a
Ingestion: Ingestion not likely. If large amounts are swallowed, immediately call a physician.
Eye contact: Flush eyes with large amounts of tepid water for at least 15 minutes. If symptoms or
irritation occur, call a physician.
Medical conditions aggravated by No data available.
5. FIRE FIGHTING MEASURES
Suitable extinguishing media: For small fires, Class B fire extinguishing media such as
CO2, dry chemical, foam (AFFF/ATC) or water spray can be
used. For large fires, water spray, fog or foam (AFFT/ATC)
can be used. Fire fighting should be attempted only by those
who are adequately trained and equipped with proper
Specific hazards: This product is neither a flammable nor combustible
material, but will burn when heated to extremely high
MSDS ID NO.: 0109MAR019 Product name: Marathon Petroleum Coke Special protective equipment for firefighters: Avoid using straight water streams. Water spray and foam
(AFFF/ATC) must be applied carefully to avoid frothing and
from as far a distance as possible. Keep surrounding area
cool with water spray from a distance and prevent further
ignition of combustible material. Avoid excessive water
spray application. Keep run-off water out of sewers and

Marathon Petroleum Coke 64741-79-3 No data available No data available No data available
Non-carcinogenic in mice in chronic skin painting studies with coke dust. Petroleum coke was found not to be
carcinogenic in monkeys and rats in a two-year inhalation study at concentrations up to 30 mg/m3. Chronic inflammatory
changes similar to those produced by non-specific respiratory irritants were observed in some rats at the highest
exposure level. Chronic skin painting studies of coke dust in mice did not produce evidence of carcinogenicity. Petroleum
coke (delayed process and fluid process) was found not to be mutagenic in a rat in vivo bone marrow cytogenetic test, a
mouse lymphoma assay and an Ames mutagenicity assay.
12. ECOLOGICAL INFORMATION
Ecotoxicity effects: This product is not expected to cause any acute or chronic toxicity to aquatic
organisms due to its extremely low water solubility.
