Hazard Information
Hazard: Highly flammable solid. Reacts violently with water, liberating flammable gas (hydrogen) and heat. Causes severe skin burns and eye damage.
Safety: Handle under inert oil or dry inert gas. Use tongs. Wear protective gloves, face shield, and fire-resistant clothing. Keep away from water.
Storage: Store under mineral oil or dry kerosene in a tightly closed container in a cool, dry, well-ventilated place away from water and oxidizers.
