Notes to Physician: Treat symptomatically, no specific antidote
Suitable Extinguishing Media: Use water spray, dry powder, CO2, or foam for surrounding materials
Specific Hazards: Not flammable, but fine dust may contribute to explosion risk if mixed with air
Protective Equipment: Use self-contained breathing apparatus and protective clothing in case of significant fire or dust exposure
Special Procedures: Cool containers with water spray if exposed to fire; prevent runoff from entering drains
Personal Precautions: Restrict access, prevent dust buildup, wear appropriate respiratory protection
Spill Cleanup Methods: Use vacuum with HEPA filter or wet methods to prevent ongoing dust; avoid sweeping
Environmental Precautions: Avoid discharge to drains and surface waters; contain spill with non-combustible absorbent
Handling: Ensure good ventilation; minimize dust generation; keep packaging closed when not in use
Storage Conditions: Store in a dry, cool, well-ventilated area; keep away from sources of moisture; avoid contact with incompatible materials like hydrofluoric acid
Incompatible Materials: Avoid storing with strong acids, bases, or oxidizers; keep away from food and animal feed
Hygiene Measures: Wash hands after use, prevent eating or drinking in handling area
Occupational Exposure Limits: OSHA PEL (Total Dust): 15 mg/m3; OSHA PEL (Respirable Dust): 5 mg/m3
Engineering Controls: Use local exhaust ventilation, process enclosures, or other engineering controls to control airborne dust
Personal Protective Equipment (PPE): Use dust-proof goggles, NIOSH-approved respirator in case of inadequate ventilation, chemical-resistant gloves, protective clothing as needed
Environmental Controls: Prevent dust from reaching drains or entering soil
