First Aid Measures

Inhalation: Move to fresh air immediately, keep person warm and at rest, provide oxygen if breathing becomes difficult
Skin Contact: Remove contaminated clothing, wash affected area with plenty of soap and water, do not delay medical attention if irritation persists
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present and easy to do, seek medical advice for persistent irritation
Ingestion: Rinse mouth with clean water, do not induce vomiting, seek medical attention promptly if symptoms occur

Fire-Fighting Measures

Suitable Extinguishing Media: Carbon dioxide, dry chemical powder, alcohol-resistant foam
Unsuitable Extinguishing Media: High-pressure water jet, which may spread the fire
Hazardous Combustion Products: Acrid smoke, carbon oxides, irritating fumes
Specific Hazards: Material at high temperatures produces vapors that can form explosive mixtures with air
Protective Equipment for Firefighters: Full protective clothing, self-contained breathing apparatus
Special Precautions: Cool exposed containers with water spray to prevent pressure build-up or explosion

Accidental Release Measures

Personal Precautions: Evacuate the area, use personal protective equipment, avoid inhalation and skin contact
Environmental Precautions: Prevent entry into drains, surface or groundwater, contain spill using absorbent material
Methods for Clean-Up: Collect spillage with non-combustible, absorbent materials like sand or silica, place in suitable container for disposal, ventilate area
Reference to Other Sections: Refer to Section 8 for personal protection and Section 13 for disposal

Handling and Storage

Safe Handling: Handle in well-ventilated location, avoid skin and eye contact, ensure containers are tightly closed, use proper grounding to prevent static discharge
Safe Storage: Store in cool, dry, well-ventilated space away from direct sunlight and ignition sources, maintain container integrity to avoid leaks, keep away from strong oxidizing agents and acids
Special Rules for Transfer: Use pump or gravity feed to minimize splashing and aerosol generation, label containers clearly

Exposure Controls and Personal Protection

Exposure Limits: No established occupational exposure limits for this compound, minimize exposure through good hygiene practices
Engineering Controls: Local exhaust ventilation, general room ventilation
Hand Protection: Chemical-resistant gloves made from butyl rubber or nitrile
