Section 3 Hazard Identification (Also see section 11)
May be harmful if swallowed. May cause irritation. Avoid breathing vapors, or dusts. Use with adequate ventilation. Avoid contact with eyes, skin, and clothes. Wash thoroughly after handling. 
Section 4 First Aid Measures
May be harmful if swallowed. May cause irritation. Avoid breathing vapors, or dusts. Use with adequate ventilation. Avoid contact with eyes, skin, and clothes. Wash thoroughly after handling.

FIRST AID: SKIN: Wash exposed area with soap and water. If irritation persists, 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: If swallowed, induce vomiting immediately after giving two glasses of water. Never give anything by mouth to an unconscious 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.
Fire Fighting Procedure:Wear self-contained breathing apparatus and protective clothing to prevent contact with skin and clothing.
Section 6 Accidental Release Measures
Eliminate Ignition Sources. Absorb with vermiculite or other inert material. Place in container. If fire hazard exists, blanket spill with alcohol foam or use water spray to disperse vapors.
Section 7 Handling and Storage
Use in a well ventilated area. Keep container closed when not in use. Do not get on skin in eyes or on clothing. Do not expose to temperatures avove 140 deg F. 
Section 8 Exposure Controls & Personal Protection
Respiratory Protection:NIOSH/MSHA-approved respirator
Ventilation: Mechanical: Hand Protection:Wear appropriate gloves to prevent skin exposure
Local Exhaust: Eye Protection:Splash Goggles
Other Protective Equipment: Wear appropriate clothing to prevent skin exposure. Use in a well ventilated area.
