Inhalation: Remove patient to fresh air, monitor breathing. Seek medical attention if symptoms linger.
Skin Contact: Wash area thoroughly with soap and water; remove contaminated clothing. If irritation continues, contact a doctor.
Eye Contact: Rinse immediately with plenty of water for at least 10 minutes, holding eyelids open. Don’t rub.
Ingestion: Rinse mouth thoroughly, do not induce vomiting. Get medical help if discomfort persists.
Suitable Extinguishing Media: Water spray, dry chemical, foam, or carbon dioxide.
Unsuitable Extinguishing Media: Avoid direct stream of water on molten material.
Specific Hazards: Thermal decomposition can release toxic gases such as nitrogen oxides, phosphorus oxides, ammonia.
Special Protective Equipment: Firefighters should wear self-contained breathing apparatus, chemical-resistant suit.
Advice for Firefighters: Cool exposed containers with water spray to reduce pressure buildup.
Personal Precautions: Use PPE including dust mask and chemical resistant gloves; avoid breathing dust, provide ventilation.
Environmental Precautions: Prevent entry into waterways, drains, and soil. Collect spillage for disposal.
Cleanup Methods: Scoop up mechanically, avoid creating dust. Collect in labeled containers, wash area with water after cleanup.
Handling: Use in well-ventilated spaces. Wear appropriate gloves, safety glasses, and dust mask. Prevent dust buildup. Wash hands after use.
Storage: Keep container tightly closed in a dry, cool, well-ventilated place. Store away from strong acids, alkalis, food and feedstuffs. Avoid humidity; material may cake or degrade if exposed to moisture.
Engineering Controls: Install local exhaust ventilation. Use dust collection systems if possible.
Personal Protection: Use safety goggles, chemical-resistant gloves, approved dust mask (N95 or equivalent). Wear work clothes that cover skin.
Hygiene Measures: Do not eat, drink, or smoke during handling. Wash thoroughly after handling.
