SECTION II – HEALTH HAZARD DATA

MATERIAL INFORMATION

Calcined petroleum coke is not considered to be hazardous as defined by OSHA’s Hazard Communication Standard 29 CFR 

1910.1200. Calcined petroleum coke is considered to be an inert material.

Calcined Petroleum Coke CAS NO. 64743 – 05 - 01

EXPOSURE LIMITS

OSHA: PEL = 15 mg/m3 as total dust; 5 mg/m3as respirable fraction

ACGIH: PEL = 10 mg/m3as total dust; 3 mg/m3as respirable fraction

SYMPTOMS OF OVEREXPOSURE

Route(s) of Entry: Inhalation, skin, and eye contact.

This product is nontoxic. The “nuisance dust” exposure values that are listed apply to any inert substance capable of producing 

airborne particulates. Excessive concentrations of calcined petroleum coke may reduce visibility, cause unpleasant deposits in the 

eye, ears, and nasal passages, or irritate the skin or mucous membranes by mechanical means. However, normal workplace 

exposure has not been determined to cause a significant health effect. Calcined petroleum coke, as with many petroleum products, 

may cause minor skin, eye, or lung irritation, but good hygienic practices can minimize these effects.

See Section VIII for additional health data.

Is product listed as Carcinogen or Potential Carcinogen by: NTP? No IARC? No OSHA? No

RECOMMENDED FIRST AID TREATMENT

Inhalation: Remove to fresh air. If breathing has stopped, administer artificial respiration and supply oxygen. If problems persist, 

seek medical attention.

Eye Contact: In case of contact, immediately flush eyes with plenty of water until irritation subsides. If irritation persists, seek 

medical attention.

Skin Contact: Normal skin contact is not known to cause a significant health effect. Particles should be periodically washed off of 

skin with soap and water.

Ingestion: If swallowed, do not induce vomiting. Immediately give water. Never give anything by mouth to an unconscious 

person. If symptoms develop, seek medical attention.

SPECIAL FIRE FIGHTING PROCEDURES Most reported coke fires have occurred when produced calcined coke is 

inadequately cooled and stored in a manner that allows the movement of air through the coke bed. Coke should be well quenched 

or cooled before it is stored in a pile out of doors or placed in silos or bins. Storage should be arranged to prevent movement of air 

through the coke. Should a fire occur, its locations and extent should be determined as quickly as possible. The best procedure is 

to dig out and remove the coke in the heated zone. The hot coke should be drenched with water as it is exposed. Because of the 

possibility of steam explosion, great care should be used introducing water into confined storage such as a silo. Whenever 

possible, bulk material in silos should be removed and material drenched in an open area. Products of combustion may contain 

carbon monoxide, carbon dioxide and sulfur dioxide. Do not enter permitted confined space or enclosed area without proper PPE.

There is no dust explosion hazard from calcined petroleum coke.

SECTION VI – SPILL OR LEAK PROCEDURES

STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED

Material is not toxic and can be picked up by sweeping, shoveling, or vacuuming. Provisions should be made to prevent washing, 

draining, or directing material to storm or sanitary sewers.

WASTE DISPOSAL METHOD

All Federal, State, and Local regulations regarding health and pollution must be followed for disposal of calcined petroleum coke.

SECTION VII – SPECIAL PROTECTION INFORMATION

RESPIRATORY PROTECTION (Specify type)

Select appropriate NIOSH-approved protection where necessary to maintain exposures below the acceptable limits in the Health 

Hazard Section. Proper respiratory selection should be determined by adequately trained personnel and based on the 

contaminant(s), the degree of potential exposure and published respirator protection factors.

VENTILATION

Dust should be controlled at point of operation.

PROTECTIVE GLOVES

None

EYE PROTECTION

None required. Recommend using dust goggles in areas of high dust concentrations.

OTHER PROTECTIVE EQUIPMENT

None

SECTION VIII – ADDITIONAL HEALTH DATA

Petroleum coke was found to be 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.

Petroleum coke was found not to be mutagenic in a rat in vivo Bone Marrow Cytogenetic test, a mouse Lymphoma assay, and an 

Ames Mutagenicity assay.
