Section 3 Hazards Identification
Label precautionary statements:
Flammable
Irritant
Irritating to eyes, respiratory system and skin.
Keep away from sources of ignition – NO SMOKING.
In case of contact with eyes, rinse immediately with plenty of water and seek medical advice.
Wear suitable protective clothing, gloves and eye/face protection.

Section 4 First-Aid Measures
In case of contact, immediately flush eyes or skin with copious amounts of water for at least 15 minutes while removing contaminated clothing and shoes.
If inhaled, remove to fresh air. If not breathing give artificial respiration. If breathing is difficult, give oxygen.
If swallowed, wash out mouth with water provided person is conscious. Call a physician.
Wash contaminated clothing before reuse.

Section 5 Fire Fighting Measures
Extinguishing media: Carbon dioxide, dry chemical powder or appropriate foam. Water may be effective for cooling, but may not effect extinguishment.
Special fire-fighting procedures: Wear self-contained breathing apparatus and protective clothing to prevent contact with skin and eyes.
Flammable.
Use water spray to cool fire-exposed containers.
Unusual fire and explosions hazards:
Vapor may travel considerable distance to source of ignition and flash back.
Container explosion may occur under fire conditions.
Forms explosive mixtures in air.

Section 6 Accidental Release Measures
Evacuate area.
Shut off all sources of ignition.
Wear self-contained breathing apparatus, rubber boots and heavy rubber gloves.
Cover with an activated carbon absorbent. Take up and place in closed containers. Transport outdoors.
Ventilate area and wash spill site after material pickup is complete.

Section 7 Handling and Storage
Refer to Section 8.

Section 8 Exposure Controls/Personal Protection
Wear appropriate NIOSH/MSHA approved s, chemical-resistant gloves, safety goggles, other protective clothing. Mechanical exhaust required. Safety shower and eye bath. Use non-sparking tools. Do not breathe vapor. Avoid contact with eyes, skin and clothing. Wash thoroughly after handling. Keep tightly closed. Keep away from heat, sparks and open flame. Store in a cool dry place.
