General Advice: Move individual away from exposure; seek medical assistance if symptoms persist
Inhalation: Remove to fresh air; provide artificial respiration if breathing has stopped
Skin Contact: Wash thoroughly with soap and water; remove contaminated clothing
Eye Contact: Flush eyes with water for at least 15 minutes; seek medical attention if irritation develops
Ingestion: Rinse mouth with water; do not induce vomiting; call a physician if large quantities are swallowed
Suitable Extinguishing Media: Use water spray, foam, dry chemical, or carbon dioxide
Unsuitable Media: Strong water jets may disperse product powder
Specific Hazards: Product decomposes at elevated temperatures releasing nitrogen oxides, hydrogen chloride
Protective Equipment: Firefighters should use full protective gear and self-contained breathing apparatus
Special Procedures: Evacuate area; contain runoff from fire control or dilution for appropriate disposal
Personal Precautions: Wear dust mask or respirator; prevent contact with eyes and skin
Environmental Precautions: Prevent large spills from entering surface water, soil, or drainage systems
Cleanup Procedures: Sweep or vacuum spilled powder in a controlled manner; avoid creating airborne dust; place in marked, sealable container for disposal
Disposal: Manage as chemical waste; follow local environmental regulations
Handling: Use only with adequate ventilation; avoid creating or breathing dust; practice frequent hand washing and keep container tightly closed upon non-use
Storage: Store in cool, dry place away from direct light, heat, oxidizers; maintain original packaging or tightly sealed container; protect from moisture; store away from incompatible materials
Specific Practices: Designated area for laboratory or bulk handling; clearly labeled shelves; regular inspection for deterioration or contamination of stock
Permissible Exposure Limit (PEL): Not officially assigned specific limits; good industrial hygiene dictates minimizing airborne concentrations
Engineering Controls: Use local exhaust ventilation or process enclosure to reduce dust formation
Respiratory Protection: Dust masks for routine handling; respirators for large spills or insufficient ventilation
Skin Protection: Lab coats, gloves resistant to powders, closed footwear
