Thermal Decomposition: May release toxic or irritating fumes under fire conditions
Personal Precautions: Evacuate personnel to safe areas; avoid dust formation; ensure adequate ventilation; wear proper protective equipment
Spill Containment: Prevent product from entering drains or waterways; use inert absorbent material (sand, vermiculite); secure contaminated area
Clean-Up Method: Collect spill with a suitable tool and place in a chemical waste container; clean area with water and detergent; ventilate area
Environmental Precautions: Prevent further leakage or spillage if safe to do so; inform authorities if large spills threaten the environment
Handling: Work in a fume hood or well-ventilated space; avoid contact with skin, eyes, and clothing; do not ingest, breathe vapors, or dust; keep containers tightly closed when not in use; follow standard laboratory safety protocols
Storage: Store in original, tightly-sealed containers in a cool, dry, and well-ventilated area away from heat, sparks, and incompatible substances; avoid direct sunlight; provide secondary containment to avoid spills
Incompatible Materials: Strong oxidizing agents, strong acids or bases, reactive metals
Hygiene Measures: Wash thoroughly after handling; do not eat, drink, or smoke in work area; keep work clothes separate from casual wear
Exposure Limits: No established occupational exposure limit; minimize exposure based on general chemical safety practices
