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 unconcious person.
Section 5 Fire Fighting Measures
Fire Extinguisher Type:Carbon Dioxide, dry chemical powder or appropriate foam
Fire/Explosion Hazards:Vapor may travel considerable distance to source of ignition and flash back. Containers may explode under fire conditions.
Fire Fighting Procedure:Wear self-contained breathing apparatus and protective clothing to prevent contact with skin and clothing.
Section 6 Accidental Release Measures
Evacuate area. Wear self-contained breathing apparatus and protective clothing. Eliminate all sources of ignition. Absorb spill with inert material, then place in a chemical waste container.
