Give artificial respiration if not breathing. If breathing is difficult, oxygen should be administered by qualified personnel. Get immediate medical attention. Skin For contact with molten product, do not remove contaminated clothing. For thermal burns, cool affected areas as quickly as possible by drenching or immersing in water. Get medical attention. If dust or fumes from molten material contact the skin, remove contaminated clothing. Wash all affected skin areas with warm soapy water. Skin contact causes photosensitization which can last for hours after exposure. Keep out of direct sunlight for the next two to three days to avoid sunburn to the photosensitized skin areas. Use a broad spectrum blockout cream to protect against UV alpha ray exposure. Get medical attention, if needed. Eyes 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 swallowed, get medical attention. Do not give anything by mouth to unconscious or convulsive person. If vomiting occurs, keep head lower than hips to help prevent aspiration. * * * Section 5 - FIRE FIGHTING MEASURES * * * See Section 9 for Flammability Properties NFPA Ratings: Health= 2 Fire= 1 Reactivity= 0 Hazard Scale: 0 = Minimal 1 = Slight 2 = Moderate 3 = Serious 4 = Severe Flammable Properties During fire conditions, vapors and decomposition products may be released, forming flammable/explosive mixtures in air. Containers may rupture or explode if exposed to heat. Page 2 of 15 Issue Date 11/15/12 Revision

3 Sensitivity to Mechanical Impact No Sensitivity to Static Discharge No Extinguishing Media regular dry chemical, carbon dioxide, regular foam, water spray Unsuitable Extinguishing Media Do not use high-pressure water streams. Protective Equipment and Precautions for Firefighters Wear full protective fire fighting gear including self contained breathing apparatus (SCBA) for protection against possible exposure. Fire Fighting Measures Avoid inhalation of material or combustion by-products. Stay upwind and keep out of low areas. Use extinguishing agents appropriate for surrounding fire. Flood with fine water spray. Directly spraying water or foam onto hot burning product may cause frothing. For fires in cargo or storage area: Cool containers with water from unmanned hose holder or monitor nozzles until well after fire is out. If this is impossible then take the following precautions: Keep unnecessary people away, isolate hazard area and deny entry. Withdraw immediately in case of rising sound from venting safety device or any discoloration of tanks due to fire. When the solid material is heated (as in a fire) it will melt and begin to flow. Molten material may be cooled and solidified using a water fog or fine water spray. Thermal Decomposition Products Combustion Products: oxides of carbon, oxides of nitrogen, oxides of sulfur, polynuclear aromatic hydrocarbons * * * Section 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 Spill / Release Stop leak if possible without personal risk. To prevent liquid from flowing into drains, completely contain spilled material with dikes, sandbags, etc. Allow spilled material to cool and solidify before attempting to clean up. Shovel solidified material into containers for recycle if clean or disposal if contaminated. The solid or solidified spillage should be cleaned up as quickly as possible. Spilled material in a traffic area will break down with mechanical contact (eg. vehicle tires) and become a wind borne dust. Solid material spillage may be wet down with a fine water spray to suppress dust during cleanup. Collect spilled material in appropriate container for disposal. In Canada, report releases to provincial authorities, municipal authorities, or both, as required. Due to the concentration of Benzo(a)pyrene and the CERCLA (40 CFR 302.4) reportable quantity of 1 pound, the release of 60 pounds (5.3 gallons) of this product requires National Response Center notification. * * * Section 7 - HANDLING AND STORAGE * * * Handling Procedures Avoid breathing vapors of heated materials. Avoid contact with eyes, skin and clothing. When using, do not eat, drink or smoke. Wash exposed areas thoroughly with soap and water, or a waterless handcleaner, after skin contact and before eating, drinking, using tobacco 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 applied prior to application of a protective cream. Contaminated clothing should be removed and laundered before reuse. Contaminated work clothing should not be allowed out of the workplace unless laundered or decontaminated.

4 Storage Procedures Store and handle in accordance with all current regulations and standards. Label all containers. Keep container in a well-ventilated place. Keep away from heat, sparks and flame. Protect from physical damage. Notify State Emergency Response 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 emergency response planning (U.S. EPA 40 CFR 355 Part B). * * * Section 8 - EXPOSURE CONTROLS / PERSONAL PROTECTION * * * Exposure Guidelines Component Exposure Limits HIGH-TEMP.

Protective Material Types protective skin creams, chemical resistant material, heat resistant material Respiratory Protection If the applicable TLVs and/or PELs are exceeded, use canister or cartridge respirators, which are MSHA/NIOSHapproved, with organic vapor cartridges. Use a positive-pressure air-supplied respirator if there is any potential for an uncontrolled release, exposure levels are not known, or any other circumstances where air-purifying respirators may not provide adequate protection.

9 Medical Conditions Aggravated by Exposure Based on Product and Component Information respiratory disorders, skin disorders, central nervous system disorders (i.e. headache, drowsiness, dizziness, loss of coordination) Additional Information (Product) This product is coal tar pitch. Volume 35 of the IARC monograph states that there is sufficient evidence that coal tar pitches are carcinogenic in humans. IARC's conclusion is based upon studies suggesting an association between skin cancer and chronic occupational dermal exposure to coal tar pitches and upon other historical studies and anecdotal reports showing an association between dermal exposure to coal tar pitch and scrotal cancer 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 coal tar pitch volatiles in excess of the recommended permissible exposure level. Studies also suggest an association between lung cancer and chronic inhalation overexposure to coal tar pitch volatiles in excess of the recommended permissible exposure level. A recent animal study may suggest an association between lung cancer and pulmonary deposition of particulate matter originating from coal tar pitches. It is not anticipated, however, that use of this product in liquid form will create a respirable dust. * * * Section 12 - ECOLOGICAL INFORMATION * * * Component Analysis - Aquatic Toxicity PYRENE ( ) Invertebrate: 48 Hr EC50 water flea: 1.8 mg/l 1,2-BENZPHENANTHRENE ( ) Invertebrate: 2 Hr EC50 water flea: 1.9 mg/l 1,2-BENZANTHRACENE ( ) Invertebrate: 96 Hr LC50 Daphnia magna: 0.01 mg/l [Static]; 48 Hr EC50 Daphnia magna: mg/l ANTHRACENE ( ) Fish: 96 Hr LC50 Lepomis macrochirus: mg/l [flow-through]; 96 Hr LC50 Lepomis macrochirus: mg/l [static] Algae: 22 Hr EC50 Pseudokirchneriella subcapitata: mg/l Invertebrate: 48 Hr EC50 Daphnia magna: mg/l ACENAPHTHENE ( ) Fish: 96 Hr LC50 Pimephales promelas: mg/l [flow-through]; 96 Hr LC50 Oncorhynchus mykiss: mg/l [flow-through]; 96 Hr LC50 Lepomis macrochirus: mg/l [static] Algae: Invertebrate: DIBENZOFURAN ( ) Fish: 96 Hr EC50 Pseudokirchneriella subcapitata: mg/l 48 Hr EC50 Daphnia magna: 41 mg/l; 48 Hr EC50 Daphnia magna: 3.45 mg/l; 48 Hr EC50 Daphnia magna: mg/l [Static] 96 Hr LC50 Pimephales promelas: mg/l [flow-through]; 96 Hr LC50 Pimephales promelas: mg/l [static]; 96 Hr LC50 Poecilia reticulata: mg/l [static] CARBAZOLE ( ) Fish: 48 Hr LC50 Mugil cephalus: 1 mg/l [static] Algae: 60 Hr EC50 Tetrahymena pyriformis: 6.7 mg/l * * * Section 13 - DISPOSAL CONSIDERATIONS * * * Disposal Methods Dispose in accordance with all applicable regulations.
