EMERGENCY OVERVIEW
WARNING.
May form combustible dust concentrations in air

POTENTIAL HEALTH EFFECTS FROM OVEREXPOSURE

Inhalation:
Excessive dust from powdered material (>5 mg/kg) may cause mild respiratory irritation.
Ingestion:
Not likely to be toxic by ingestion.
Skin contact:
None expected from acute exposure.
Eye contact:
Dust may be a mechanical irritant.

Component Information:

4. FIRST AID MEASURES

Eye contact:
Flush eyes with large amounts of tepid water for at least 15 minutes. If symptoms
or irritation occur, call a physician.

Skin contact:
Wash with soap and large amounts of water. If symptoms or irritation occur, call a
physician.
Ingestion:
Ingestion not likely. If large amounts are swallowed, immediately call a physician.
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.

5. FIRE FIGHTING MEASURES

MSDS ID NO.: 0109MAR019 Product name: Marathon Petroleum Coke Page 2 of 7

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
(AFFF/ATC) can be used. Fire fighting should be
attempted only by those who are adequately trained and
equipped with proper protective equipment.
Specific hazards: May form combustible dust concentrations in the air. Fine
dust dispersed in sufficient concentrations in the air, and in
the presence of an ignition source is a potential dust
explosion hazard. Non-sparking tools/equipment should be
considered when a potentially combustible dust
environment exists.
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 water sources.

Flash point: >200 F

Autoignition temperature: No data available.
Flammable limits in air - lower (%): No data available.
Flammable limits in air - upper (%): No data available.

NFPA rating:
Health: 1
Flammability: 1
Instability: 1

6. ACCIDENTAL RELEASE MEASURES

Personal precautions: Dust deposits dispersed into the atmosphere in sufficient concentration may form
an explosive mixture. Advise authorities and National Response Center
(800-424-8802) if the product has entered a water course or sewer. Notify local
health and pollution control agencies, if appropriate.

7. HANDLING AND STORAGE

Handling:
Refer to applicable EPA, OSHA, NFPA and consistent state and local requirements. Contact with hot product may
cause burns. Avoid breathing dust. Avoid contact with eyes. Wash thoroughly after handling. Use good personal
hygiene practices and wear appropriate personal protective equipment (See Section# 8). Do not wear contaminated
clothing or shoes.

Storage:
To avoid the combustible dust hazard, minimize dust generation and accumulation. Routine housekeeping should be
instituted to ensure that dusts do not accumulate on surfaces. Dry powders can build static electricity charges when
subjected to the friction of transfer and mixing operations and cause an electrical spark. Provide adequate
precautions, such as electrical grounding and bonding, or nonreactive atmospheres. When stored indoors keep in a
cool, well-ventilated area. Do not expose to heat, open flames, strong oxidizers or other sources of ignition. Petroleum
Coke may be stored outdoors with proper provisions for containment.

 8. EXPOSURE CONTROLS / PERSONAL PROTECTION
PERSONAL PROTECTIVE EQUIPMENT

Engineering measures: Local or general exhaust required in an enclosed area or when there is inadequate
ventilation.

Respiratory protection: Not required under normal conditions and adequate ventilation. Use dust/ fume
respirator if use generates excessive dust/fume or concentrations exceed
permissible limits.

Skin and body protection: Gloves.

Eye protection: Dust goggles if use produces excessive dust/fume concentrations.

Toxicology Information:
Petroleum coke did not affect fertility or reproductive performance in pregnant
female rats exposed to up to 300 mg/m3, 6 hours/day for 28 days although some
portal-of-entry toxicity (inflamation, discolored lungs and increased lung weight)
was observed. 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. ECOTOXICOLOGICAL INFORMATION

Mobility:
No data available.

Ecotoxicity:
Aquatic Toxicity: No data available.

Bioaccummulation:
No data available.

Persistance/Biodegradation:
The 48 and 96 hour LL50s for a water accommodated fraction (WAF) of petroleum
coke are >1000 mg/l in both daphnia and fathead minnows, respectively. Coke did
not produce any adverse effects on fresh water algae at WAF concentrations of
>1000 mg/l. Earthworms and seedlings (corn, radish & soybean) were unaffected
by the prensence of concentrations of 1000 mg/kg coke in the soil.
