Protective Equipment: Wear self-contained breathing apparatus (SCBA) and full protective gear
Fire-Fighting Instructions: Move containers from fire area if it can be done without risk. Cool exposed containers with water spray. Keep people upwind and out of spill area.
Personal Precautions: Evacuate unnecessary personnel. Ventilate area. Prevent further leakage or spillage if safe to do so. Avoid dust formation.
Protective Equipment: Wear gloves, safety goggles, dust mask or respirator if necessary.
Environmental Precautions: Do not discharge into drains, water courses, or onto soil. Contain the spill with inert materials (sand, earth).
Cleanup Methods: Sweep up material using non-sparking tools and collect in suitable, closed containers for disposal. Wash spill site thoroughly after cleanup.
Handling: Avoid breathing dust. Minimize dust generation and accumulation. Handle with adequate ventilation. Wear protective gloves and eye/face protection. Use only in chemical fume hood or ventilated area. Wash hands thoroughly after handling.
Storage: Store in cool, dry, well-ventilated area. Keep containers tightly closed and upright. Keep away from incompatible materials such as moisture, acids, strong oxidizers. Protect from physical damage.
Specific End Uses: Laboratory synthesis, research, or for use in electrochemistry as directed by trained personnel
