Section 3 Hazard Identification (Also see section 11)
Keep away from heat and ignition sources. Harmful if swallowed. Avoid breathing vapors. Use with adequate ventilation. Avoid contact with eyes, skin, and clothes. Wash thoroughly after handling. Keep container closed. 
Section 4 First Aid Measures
Keep away from heat and ignition sources. Harmful if swallowed. Avoid breathing vapors. Use with adequate ventilation. Avoid contact with eyes, skin, and clothes. Wash thoroughly after handling. Keep container closed.

FIRST AID: SKIN: Remove contaminated clothing. Wash exposed area with soap and water. If symptoms persist, seek medical attention

EYES: Wash eyes with plenty of water for at least 15 minutes, lifting lids occasionally. Seek Medical Aid. INHALATION: Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen

INGESTION: Give several glasses of milk or water. Vomiting may ocur spontaneously, but DO NOT INDUCE! Never give anything by mouth to an unconscious person.
Section 5 Fire Fighting Measures
Fire Extinguisher Type:Alcohol Resistant Foam, Carbon Dioxide
Fire/Explosion Hazards:Carbon Oxides, and various hydrocarbons formed when burned. Highly flammable vapors, heavier than air may accumulate in low areas or spread along ground. Flash back trail possible
Fire Fighting Procedure:Wear self-contained breathing apparatus and protective clothing to prevent contact with skin and clothing.
Section 6 Accidental Release Measures
Wear protective clothing and respiratory protection from mists. Protect from ignition. Keep away from water sources and sewer. Absorb with sand clay etc.
Section 7 Handling and Storage
Store in a cool dry well ventilated area. Keep away from heat and flame. Do not get in eyes, on skin, or on clothing. 
Section 8 Exposure Controls & Personal Protection
Respiratory Protection:Organic Vapor Cartridge
Ventilation: Mechanical: Hand Protection:Solvent resistant gloves as neoprene or nitrile
Local Exhaust: Eye Protection:Splash Goggles
Other Protective Equipment: Wear appropriate clothing to prevent skin exposure
