4. First-Aid Measures

Inhalation: Remove person to fresh air and keep comfortable for breathing. Seek medical attention if symptoms persist.
Skin Contact: Wash affected area with soap and water. If irritation occurs, seek medical advice.
Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. Seek medical advice if irritation persists.
Ingestion: Rinse mouth. Do not induce vomiting. Seek medical attention if large quantities are ingested.

5. Fire-Fighting Measures

Suitable Extinguishing Media: Use water spray, alcohol-resistant foam, dry chemical, or carbon dioxide.
Unsuitable Extinguishing Media: None known.
Specific Hazards: Not flammable. May release harmful gases if involved in a fire.
Protective Equipment: Wear self-contained breathing apparatus and full protective gear.

6. Accidental Release Measures

Personal Precautions: Use appropriate personal protective equipment. Avoid contact with skin and eyes. Ensure adequate ventilation. Evacuate personnel from the affected area.
Environmental Precautions: Prevent further spillage if safe to do so. Do not allow to enter drains or watercourses.
