Impurities: Trace amino acids and inorganic salts, less than 2% in total
Other Components: Water of crystallization, if present, does not substantially affect safety
Eye Contact: Immediately flush eyes with plenty of water for at least 15 minutes, lifting upper and lower eyelids occasionally; seek medical attention if irritation develops or persists
Skin Contact: Wash affected area with mild soap and water, remove contaminated clothing; medical attention for persistent irritation
Inhalation: Move to fresh air, support breathing as needed; consult a physician if symptoms, such as coughing or throat irritation, persist
Ingestion: Rinse mouth with water, do not induce vomiting, drink water to dilute; if symptoms occur or persist, seek medical advice
Medical Attention: Treat symptomatically, supportive care based on presentation
Suitable Extinguishing Media: Water spray, foam, dry powder, or carbon dioxide; avoid direct water jets

Hazardous Combustion Products: Nitrogen oxides, carbon dioxide, carbon monoxide, and hydrogen chloride may be released in high heat
Protective Equipment for Firefighters: Wear full protective clothing and self-contained breathing apparatus
Special Firefighting Procedures: Cool containers with water spray to prevent overheating; prevent runoff into waterways
Fire/Explosion Hazards: Dust accumulation could theoretically present a weak explosion risk, though extremely low
Personal Precautions: Avoid dust formation, wear suitable gloves, eye/face protection, and dust mask
Environmental Precautions: Prevent large spills from entering drains, surface water, or soil
Containment: Clean up spill immediately with appropriate PPE, sweep up or vacuum in well-ventilated area
Cleanup Methods: Collect and place spilled product in a suitable, labeled container for disposal, wash area with water
Other Notes: Prevent airborne dust generation as much as possible
Safe Handling: Avoid creating and breathing dust, minimize exposure by using local exhaust ventilation; use personal protective equipment
Safe Storage: Store in original tightly closed container in a cool, dry, well-ventilated area away from incompatible substances like strong oxidizers
Hygiene Practices: Wash thoroughly after handling; do not eat, drink, or smoke in storage or use areas
Special Considerations: Protect from moisture and sources of contamination
Exposure Limits: No established regulatory occupational exposure limits; internal guidelines recommend minimizing exposure to airborne dust
Engineering Controls: Local exhaust ventilation, dust extraction if process generates dust
