First Aid Measures

Skin Contact: Rinse immediately with plenty of water; remove contaminated clothing; seek medical attention if irritation develops
Eye Contact: Flush eyes with plenty of water for at least 15 minutes; lift eyelids occasionally; get medical attention if symptoms persist
Inhalation: Remove victim to fresh air; if symptoms are severe or persist, seek medical attention
Ingestion: Rinse mouth; drink water if victim is conscious; do not induce vomiting; seek medical attention
Notes to Physician: Treat symptomatically; risk of irritation or chemical burns on prolonged exposure

Fire-Fighting Measures

Suitable Extinguishing Media: Water spray, dry chemical, foam, carbon dioxide
Unsuitable Extinguishing Media: Direct jet of water (spreads material)
Specific Hazards: Thermal decomposition can produce oxides of nitrogen, sulfur oxides, ammonia, and carbon dioxide
Protective Equipment and Precautions: Firefighters wear self-contained breathing apparatus and full protective gear; avoid breathing vapors; cool containers exposed to flames with water spray
Fire Hazard Response: Evacuate area; prevent run-off into drains or waterways

Accidental Release Measures

Personal Protection: Wear protective clothing, gloves, eye protection
Spill Cleanup: Absorb with inert material (sand, earth); collect into containers for disposal; wash area with water; avoid creating splashes
Environmental Precautions: Prevent product from entering drains, waterways, soil; inform appropriate authorities in event of large spill
Decontamination: Rinse area with water after removal; ventilate area
Special Attention: Wet floors may become slippery; use caution to avoid falls

Handling and Storage
