### SECTION II – HEALTH HAZARD DATA

MATERIAL INFORMATION

Calcined petroleum coke is not consider ed 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 – 100% CAS NO. 64743 – 05 - 01

EXPOSURE LIMITS

OSHA: PEL = 15 mg/m 3 as total dust; 5 mg/m 3 as respirable fraction

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

SYMPTOMS OF OVEREXPOSURE

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

This product is nontoxic. The “nuisance dust” exposure values that are listed apply to any inert substance capable of producin g 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 mechan ical means. Howeve r, normal workplace exposure has not been determined to cause a significant health effect. Calcined petroleum coke, as with many petroleum product s, 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 p ersist,

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 signifi cant health effect. Particles should be periodically washed o ff of skin with soap and water.

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

p erson. If s y m p toms develo p, seek medical attention.

SPECIAL FIRE FIGHT ING 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 ou t of doors or placed in silos or bins. St orage should be arranged to prevent movemen t of air through the coke. Should a fire occur, its locations and extent should be determined as quickly as possible. The best procedu re 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 th e possibility of steam explosion, great care should be used introdu cing 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 perm itted confined space or enclos ed area without proper PPE. There is no dust explosion hazard from calcined petroleum coke.

UNUSUAL FIRE AND EXPLOSION HAZARDS May burn if exposed to temperatures greater 1290 o F (700 o C).

## 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 co ke.



## SECTION VII – SPECIAL PR OTECTION INFORMATION

RESPIRATORY PROTECTION (Specify type)

Select appropriate NI OSH-approved protection where necessa ry to maintain exposures below th e acceptable limits in the Health Hazard Section. Proper respiratory sel ection should be determined by adequate ly trained personnel and based on the

contaminant ( s ), the de g ree of p otential ex p osure and p ublished res p irator p rotection fac t ors.

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 – ADDITION AL 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/m 3 . Chronic inflammatory changes similar to those produ ced 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.
