### 4. FIRST AID MEASURES

INHALATION: If adverse effects occur, remove to uncontamin ated area. Give artific ial respiration if not breathing. If breathing is difficult, oxygen should be administered by qua lified personnel. Get immediate
medical attention.

SKIN CONTACT: For thermal burns, cool affected areas as quickly as possible by drenching or immersing in water. Wash skin with soap and water for at l east 15 minutes, or use a wa terless handcleaner, while removing contaminated clothing and shoes. Get immediate medical attention, if needed.EYE CONTACT: Immediately flush eyes with plenty of water for at least 15 minutes. Get medical attention, if needed.

INGESTION: DO NOT induce vomiting. If a large amount is sw allowed, get medical attention. Do not give anything by mouth to unconscious or c onvulsive person. If vomiting occurs, keep head lower than hips to help prevent aspiration.



### 5. FIRE FIGHTING MEASURES

FIRE AND EXPLOSION HAZARDS: During fire conditions, vapors a nd decomposition products may be released, forming flammable/explosive mi xtures in air. Containers may rupt ure or explode if exposed to heat.

EXTINGUISHING MEDIA: regular dry chemical, carbon di oxide, regular foam, water spray

FIRE FIGHTING: Avoid inhalation of material or combustion by-products. St ay upwind and keep out of low areas. Use extinguishing agents a ppropriate for surrounding fire. Flood with fine water spray. Directly spraying water or foam onto hot burning product may cause frothing. For fires in carg o or storage area: Cool
containers with water from unmanned hose holder or monito r nozzles until well after fire is out. If this is impossible then take the following precautions: Keep unn ecessary people away, isolat e hazard area and deny entry. Withdraw immediately in case of rising sound from venting safety de vice or any discoloration of tanks
due to fire.

FIRE FIGHTING PROTECTIVE EQUIPMENT: Full fire fighting turn-out gear (bunker gear).

SENSITIVITY TO MECHANICAL IMPACT: No

SENSITIVITY TO STATIC DISCHARGE: Yes (dust)

FLASH POINT: >374 F (>190 C) (PMCC) AUTOIGNITION: >750 F (>399 C) FLAMMABILITY CLASS (OSHA): IIIB



### 6. ACCIDENTAL RELEASE MEASURES

WATER RELEASE: Subject to California Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65). Keep out of water supplies and sewers.

OCCUPATIONAL RELEASE: Stop leak if possible without personal risk. Small spills: Absorb with sand or other non-combustible material. Collect spilled material in appropr iate container for disposal. In Ca nada, report releases to provincial authorities, municipal author ities, or both, as required. Due to the concentration of Benzo(a)pyrene and the CERCLA (40 CFR 302.4) reportable qua ntity of 1 pound, the release of 70 pounds (6 gallons) of this product requires National Response Center notification.

### 7. HANDLING AND STORAGE

STORAGE: Store and handle in accordance with all current regulations and standards. Label all containers. Keep container in a well-v entilated place. Keep away from heat, sparks and flame. Protect from physical damage. Notify State Emergency Res ponse Commission for storage or use at amounts greater than or equal to the TPQ (U.S. EPA SARA Section 302). SARA Section 303 requires facilities storing a material with a TPQ to participate in local emergenc y response planning (U.S. EPA 40 CFR 355.30).

HANDLING: Avoid breathing vapors of heated materials. Avoid contact with ey es, skin and clothing. When using, do not eat, drink or smoke. Wash exposed ar eas thoroughly with soap an d water, or a waterless handcleaner, after skin contact a nd before eating, drinking, using t obacco products, or restrooms. Use protective skin cream on exposed skin before and during work shift. To reduce sun sensitivity a sun-blocking lotion (SPF 15+) can also be applie d prior to application of a prot ective cream. Contaminated clothing
should be removed and laundered before reuse.

### 11. TOXICOLOGICAL INFORMATION

CARBON PITCH LIQUID: CARCINOGEN STATUS: OSHA: No, NTP: Yes, IARC: Yes, (S ee below for additional information on component carcinogen status) TARGET ORGANS: respiratory tract system, sk in, eyes, bladder, scrotum MEDICAL CONDITIONS AGG RAVATED BY EXPOSURE: respiratory disorders, skin disorders, central nervous system disorders (i.e. headache, drowsiness, dizziness, loss of coordination) ADDITIONAL DATA: This product is coal tar pitch. Volume 35 of the IARC monograph states that there is sufficient evidence that coal tar pitches are car cinogenic in humans. IARC's conclusion is based upon studies suggesting an association betw een skin cancer and chronic occupa tional dermal exposure to coal tar pitches and upon other historical st udies and anecdotal reports showi ng an association between dermal exposure to coal tar pitch and scrotal can cer in the absence of good hygiene practices.Epidemiological studies of aluminum reduction workers showed an excess risk of developing bladder cancer for workers with chronic inhalation overexposure to co al tar pitch vola tiles in excess of the recommended permissible exposure level. Studies also suggest an association between lung cancer and ch ronic inhalation overexposure to coal tar pitch volatile s in excess of the recommended perm issible exposure level. A recent animal study may suggest an associ ation between lung cancer and pulmona ry deposition of particulate matter originating from coal tar pitches. It is not anticipate d, however, that use of this product in liquid form will create a respirable dust.
