Inhalation: Move person to fresh air. Get medical attention if cough or discomfort persists.
Skin Contact: Remove contaminated clothing, rinse skin with plenty of water. Seek medical attention if irritation develops.
Eye Contact: Flush eyes with water for several minutes, lifting eyelids. Remove contact lenses if present. Seek medical attention for persistent redness.
Ingestion: Rinse mouth with water. Drink water to dilute. Do not induce vomiting unless directed by medical personnel.
Most Important Symptoms: Mild irritation to eyes or respiratory system possible.
Notes for Physician: Treat symptomatically. Product is not acutely toxic.
Suitable Extinguishing Media: Water spray, dry chemical, carbon dioxide, foam
Specific Hazards: Fine powder can form combustible dust clouds in air. Combustion produces carbon oxides.
Protection for Firefighters: Wear self-contained breathing apparatus and full protective gear
Unusual Fire Hazards: Dust may present explosion hazard if suspended in air and exposed to ignition source
Advice: Avoid raising dust. Cool exposed containers with water spray.
Personal Precautions: Wear dust mask, goggles, and gloves to prevent skin, eye, and inhalation exposure
Environmental Precautions: Prevent runoff into drains and surface waters
Cleanup Methods: Sweep up carefully to avoid generating airborne dust. Place in suitable waste container for proper disposal.
Spillage: Wash spill site after material pickup is complete. Maintain good ventilation.
Handling: Practice good hygiene. Avoid creating or inhaling dust. Use local exhaust if dust generated.
Technical Measures: Adequate ventilation, minimize dust generation, ground/bond bulk systems due to dust explosion risk
Storage Conditions: Store in closed container, cool dry place. Protect from moisture and direct sunlight. Keep away from oxidizing agents.
Incompatible Materials: Strong oxidizing substances
Occupational Limits: No specific regulatory exposure limits have been established
Engineering Controls: Use local exhaust, enclosures for handling large quantities
Personal Protection: Wear safety glasses with side shields, dust mask or respirator (NIOSH N95/N100 for high dust), gloves
Hygiene Measures: Wash hands after handling. Prohibit eating or smoking in work area.
