Section 4
First-Aid Measures
Eyes
Rinse with plenty of water for at least 15 minutes. Remove contact lenses if present and easy to do. Continue rinsing. Seek medical attention immediately.
Skin
Immediately flush with plenty of water for at least 15 minutes while removing contaminated clothing. Wash with soap. Get medical attention immediately.
Inhalation
Move person to fresh air and keep comfortable for breathing. If breathing is difficult, give oxygen. If not breathing, give artificial respiration. Get medical attention immediately.
Ingestion
Do Not Induce Vomiting! Never give anything by mouth to an unconscious person. If conscious, wash out mouth with water. Get medical attention immediately.
Most Important Symptoms and Effects
Eye contact causes serious eye damage: pain, redness and corneal injury, which may be permanent.
Inhalation of vapors may cause drowsiness, dizziness, headache and nausea.
Immediate Medical Attention and Special Treatment
Immediate medical attention is required after eye contact; eye damage may continue after exposure ends.
Section 5
Fire-Fighting Measures
Suitable Extinguishing Media
Alcohol-resistant foam, CO2, dry chemical powder. Water spray may be used to cool fire-exposed containers.
Unsuitable Extinguishing Media
Do not use a solid water stream — may scatter and spread fire.
Specific Hazards Arising from the Chemical
Vapors are heavier than air and may form explosive mixtures with air; they can travel to a source of ignition and flash back. Containers may rupture when heated.
Protective Equipment
Wear self-contained breathing apparatus and full protective clothing.
Hazardous Combustion Products
Carbon monoxide and carbon dioxide on combustion.
Section 6
Accidental Release Measures
Personal Precautions
Use PPE as described in Section 8. Ensure adequate ventilation. Evacuate personnel to safe areas.
Hazard-Specific Precautions
Eliminate all ignition sources. Use non-sparking tools and explosion-proof equipment; ground and bond containers during cleanup.
Environmental Precautions
Prevent leakage or spillage from entering drains, sewers, or waterways.
Containment & Cleanup
Absorb with inert material. Collect in appropriate waste container. Dispose per applicable regulations.
Section 7
Handling and Storage
Safe Handling
Use with adequate ventilation. Avoid contact with skin, eyes, and clothing. Wash thoroughly after handling. Keep container closed when not in use.
Safe Storage
Store in a cool, dry, well-ventilated area away from heat, sparks, and open flame. Keep away from incompatible materials (see Section 10). Keep containers tightly closed. Ground and bond containers when transferring material.
Specific Storage Precautions
Keep tightly closed in a cool, well-ventilated flammables area away from ignition sources and oxidizers. Store locked up. Ground and bond containers.
