SECTION IV - FIRE AND EXPLOSION HAZARD DATA OSHA FLAMMABILITY CLASS: FLASH POINT: -9999 deg F. METHOD USED: FLAMMABLE LIMITS IN AIR BY VOLUME - LOWER: .9% UPPER: 15.3% EXTINGUISHING MEDIA: FOAM, CO2, DRY CHEMICAL, WATER FOG SPECIAL FIREFIGHTING PROCEDURES: Evacuate all unnecessary personnel. Use full protective equipment, including self-contained breathing apparatus. Use water spray, preferably fog, to cool closed containers to prevent pressure build-up and possible explosion. Direct water stream is not recommended for oil base fires. Product may float and reignite on surface of water. Do not allow product or runoff from fire control to enter storm or sanitary sewers, lakes, rivers, streams or waterways. UNUSUAL FIRE AND EXPLOSION HAZARDS: Dangerous air-vapor mixtures may form and ignite when exposed to sparks or flame from pilot lights, stoves, heaters, electric motors, static discharge or other sources of ignition. Vapors are heavier than air and may travel along the ground to distant locations. Free falling streams of liquid may cause static electricity build-up andcreate fire hazard.

SECTION V - REACTIVITY DATA HAZARDOUS DECOMPOSITION PRODUCTS: Carbon Monoxide, Carbon Dioxide. INCOMPATIBILITY (MATERIALS TO AVOID): Acids, Alkalis, Strong Oxidizing agents. STABILITY: Stable. HAZARDOUS POLYMERIZATION: Will not occur. CONDITIONS TO AVOID: High temperature and humidity, ignition source, vapor build-up.

SECTION VI - HEALTH HAZARD DATA RIMARY ROUTE(S) OF EXPOSURE: Inhalation, skin contact, ingestion. ACUTE EFFECTS FROM SHORT TERM EXPOSURE: INHALATION: Vapors and mists may irritate nose, throat and lungs (burning, stinging, coughing). May cause headache, dizziness, nausea, weakness, shortness of breath andloss of coordination. Intentional misuse by deliberately concentrating and inhaling the contents may be harmful or fatal. EYES: Contact with liquid or vapors causes irritation (redness, watering, itching, stinging, blurred vision). SKIN: Contact may cause irritation (dryness, itching, cracking, rash andswelling). SKIN ABSORPTION: None known. 27-0041.20 MATERIAL SAFETY DATA SHEET PAGE 2 SWALLOWING: Causes nausea, vomiting and diarrhea. CHRONIC EFFECTS FROM LONG TERM/REPEATED EXPOSURE: Long-term or repeated overexposure, without proper ventilation or personal protection, may cause damage to: dermatitis or other skin disorders. MEDICAL CONDITIONS GENERALLY AGGRAVATED BY EXPOSURE: Respiratory tract irritation nausea eye disorders skin disorders sensitization to chemical substances.

SECTION VII - EMERGENCY AND FIRST AID PROCEDURES SWALLOWING: If person is conscious, give 1/2 glass milk or water. DO NOT induce vomiting. Call Poison Center, Emergency Room or Physician immediately. Note: Aspiration of solvents may result in chemical pneumonia. INHALATION: Remove from exposure to fresh air. If breathing is difficult, give oxygen. If breathing has stopped, give artificial respiration. Keep person warm and quiet. Get medical attention immediately. EYE: Immediately flush with plenty of water for 15 minutes, while lifting upper and lower eyelids. Get medical attention. SKIN: Immediately wash with soap and water. Remove contaminated clothing and shoes. Wash or clean thoroughly before reuse. Get medicalattention if irritation persists. OTHER: Have Material Safety Data Sheet available if possible when calling Poison Center, Emergency Room or Physician.

SECTION VIII - PERSONAL PROTECTION RESPIRATORY PROTECTION: Use NIOSH approved cartridge respirator to keep vapor/mist levels of hazardous ingredients (listed in section IIA) belowthe occupational exposure limits (PEL and TLV). If exposure levels are unknown, or limits exceeded, use full facepiece air-purifying cartridge respirator for organic vapors and mists. Use filters to avoid breathingspray particles or sanding dusts. Follow respirator manufacturer's instructions for use. VENTILATION: Provide general mechanical ventilation or local exhaust to keep vapor concentrations below the PEL's and TLV's in section II and Lower Flammable Limits in section IV. HAND PROTECTION: Wear impermeable gloves to prevent skin contact. Consult safety equipment supplier for specific recommendations of construction materials. EYE PROTECTION: Wear chemical goggles designed to protect eyes against vapors, liquid splash and mists unless full facepiece respirator is worn. Note: Contact lenses may contribute to the severity of an eye injury and should not be worn when working with chemicals. OTHER PROTECTIVE EQUIPMENT: Wear protective clothing, including headcap,to avoid skin contact with liquid or overspray. WORK/HYGIENIC PRACTICES: Eye washes and safety showers are recommended in the workplace. Wash hands after using and before eating, drinking orusing tobacco products. Thoroughly clean contaminated clothing and shoes before reuse. Periodically monitor exposure levels to hazardous ingredients listed in section II and review permissible limits.

SECTION IX - SPILL OR LEAK PROCEDURES STEPS TO BE TAKEN IF MATERIAL IS RELEASED OR SPILLED: Eliminate ignitionsources and ventilate area. Evacuate all unnecessary personnel. Wear full protective equipment. Dike drains to prevent entering storm or sanitary sewers, rivers, streams or waterways. Contain spill and cover with inert absorbent material. Take up using non-sparking tools (aluminum, brass or copper) and place mixture into containers for disposal. Note: Some spills or releases may require special reporting to local, state or federal agencies. WASTE DISPOSAL: Waste material and empty containers must be disposed of in accordance with all local, state and federal environmental control regulations. Use only approved waste management facilities. DOT/CERCLA: The DOT/CERCLA reportable quantity (RQ) for this product is 999999 gallons based on RQ 0 pounds.

SECTION X - SPECIAL PRECAUTIONS HANDLING PRECAUTIONS: Keep liquid and vapors away from heat, sparks and flame. Turn off or remove all sources of ignition. Use proper methods of ventilation to prevent vapor build-up. Avoid contact with hot metal surfaces. Avoid free fall of liquids in excess of a few inches. Ground fixed equipment. Bond and ground pails, drums and other transfer containers and equipment. Avoid breathing vapors, spray mists and sanding or grinding dusts. Avoid contact with eyes and skin. Do not take internally. Use adequatemethods of ventilation, respiratory and personal protective equipment. Do not reuse, weld, drill or heat empty containers which may contain explosive vapors. Follow label warnings until thoroughly cleaned or sent for disposal. Do not remove or deface label. Do not transfer to unlabeled container. SHIPPING AND STORAGE PRECAUTIONS: Keep container closed when not in use and during transit. Do not store above 120°F. Keep in upright positionand protect container from damage. Store in buildings or areas designedand protected for storage of products with this flammability rating. Keep out of reach of children. Do not store where contact with incompatible material could occur, even during an accidental spill or release.
