Notes to Physician: Treat symptomatically, monitor for elevated calcium levels with substantial ingestion
Suitable Extinguishing Media: Water spray (fog), foam, carbon dioxide, dry chemical powder
Specific Hazards: Product combusts to release carbon monoxide, carbon dioxide, possibly irritating vapors
Protective Equipment: Firefighters require self-contained breathing apparatus (SCBA), standard protective gear
Special Precautions: Avoid inhaling combustion fumes, evacuate area if significant powder involved
Personal Precautions: Use personal protective equipment, avoid dust formation, ensure adequate ventilation
Environmental Precautions: Prevent entry into drains, sewers, and surface water, contain spillage
Methods for Clean-Up: Gather spilled powder with damp cloth or absorbent materials, place in labeled waste container, clean area with water
Handling: Wear lab gloves, goggles, and dust mask, minimize dust generation, practice good hygiene
Storage: Store tightly sealed in a cool, dry place, protect from light and moisture, keep away from incompatible materials (strong oxidizers), maintain standard pharmaceutical storage protocols
Incompatible Products: Oxidizing acids, strong bases
Engineering Controls: Work under local exhaust, handle in well-ventilated area
Personal Protective Equipment: Laboratory coat, safety glasses, chemical-resistant gloves, dust mask or respirator for large spills
