Ingestion: Rinse mouth with water;
seek medical advice if feeling unwell or if large quantities were swallowed
Suitable Extinguishing Media: Water spray, dry chemical, carbon dioxide, or foam
Specific Hazards: May generate irritating fumes when decomposed by fire
Protective Equipment For Firefighters: Wear self-contained breathing apparatus and standard protective gear
Firefighting Procedures: Avoid breathing combustion gases; use water to cool exposed containers from a safe distance
Personal Precautions: Avoid inhaling dust, avoid skin and eye contact
Environmental Precautions: Prevent entry into sewers and waterways
Clean-up Procedures: Collect spill using non-sparking tools, store in labeled closed containers for disposal; ventilate area and wash down residues
Safe Handling: Minimize dust generation; handle with dry, clean protective gear; wash hands thoroughly; do not eat, drink, or smoke while handling
Storage Conditions: Store in tightly closed containers in cool, dry, well-ventilated locations, away from strong oxidizers and acids; keep away from moisture to avoid clumping
Occupational Exposure Limits: No specific OSHA PEL or ACGIH TLV; limit exposure to nuisance dusts (respirable, total particulate)
Engineering Controls: Use local exhaust ventilation or process enclosures to control airborne dust levels
Personal Protective Equipment: Safety goggles, dust mask (N95 or better), gloves, laboratory coat or appropriate industrial coveralls
