Firefighting Instructions: Stay upwind, move containers from fire area if safe, keep containers cool by spraying with water, prevent run-off from entering drains
Personal Precautions: Wear safety goggles, gloves, dust mask or respirator, and protective clothing to avoid skin and eye contact, ventilate area
Environmental Precautions: Prevent product from entering drains, water courses, or soil
Methods for Cleanup: Sweep up gently and place in suitable, labeled containers for disposal; avoid creating dust; clean spill area with water after initial pickup
Emergency Procedures: Evacuate unnecessary personnel, notify management of large release; dispose cleaning materials in accordance with local regulations
Precautions for Safe Handling: Avoid contact with skin, eyes, and clothing; use only with adequate ventilation; do not breathe dust; handle with care to minimize dust generation
Conditions for Safe Storage: Store in tightly closed containers in a cool, dry, and well-ventilated area; keep away from moisture, heat sources, and incompatible materials such as oxidizing agents and strong bases
Incompatible Materials: Avoid storing near strong alkalis, oxidizing compounds, or reactive metals
Other Notes: Keep out of reach of children and unauthorized personnel; label storage area clearly
Exposure Limits: No established workplace exposure limits for pure material; recommend using sensible exposure control based on dust hazards
Engineering Controls: Use local exhaust ventilation to keep airborne levels below recommended limits
Personal Protective Equipment: Eye protection (safety goggles), gloves resistant to chemicals, dust mask or a respirator; wear lab coat or apron for added protection
