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.

Fire-Fighting Measures

Suitable Extinguishing Media: Use water spray, alcohol-resistant foam, dry chemical, or CO2. Use measures appropriate to local circumstances.
Unsuitable Extinguishing Media: Do not use a solid water stream as it may scatter and spread fire.
Protective Equipment: Wear self-contained breathing apparatus and full protective clothing.
Hazardous Combustion Products: May include carbon oxides and other toxic fumes. See Section 10.

Accidental Release Measures

Personal Precautions: Use PPE as described in Section 8. Ensure adequate ventilation. Evacuate personnel to safe areas.
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.

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. Keep away from incompatible materials (see Section 10). Keep containers tightly closed.

Exposure Controls / Personal Protection

Occupational Exposure Limits

No established occupational exposure limits.

Engineering Controls: Use adequate ventilation. Provide eyewash stations and quick-drench showers accessible to areas of use.
Eye/Face Protection: Wear chemical safety goggles or face shield.
Skin Protection: Wear chemical-resistant gloves and protective clothing.
Respiratory Protection: Use NIOSH-approved respirator if exposure limits are exceeded or irritation occurs.
