Hazardous characteristics of sodium hydride:
Chemical reactivity is very high and can spontaneous combustion in humid air. Heat or contact with moisture, acid that release heat and hydrogen and cause combustion and explosion. It can react strongly with the oxidizer and cause combustion or explosion. When moisture and water form hydroxide, very corrosive
Sodium hydride storage considerations:
Store in a cool, dry and well-ventilated warehouse, and stay away from fire and heat source. The Library temperature shall not exceed 32℃, and the relative humidity shall not exceed 75%. Packaging seal. Should be stored separately with oxidants, acids, alcohols, halogen, etc., avoid mixed storage. Explosion-proof-type lighting and ventilation facilities are adopted. No use of mechanical equipment and tools prone to spark. The storage area shall be equipped with suitable material for the leakage.
Sodium hydride emergency treatment:
Quarantine the leakage pollution area and restrict access. Cut off the fire source. It is recommended that emergency handling personnel wear self-contained positive pressure respirators and fire protective clothing. Do not make direct contact with the leak. Small leakage: avoid dust, use no spark tools to collect in a dry, clean, covered container. Transfer of a safe place. Large leakage: cover with plastic cloth and canvas to reduce flying dispersion. Contact the relevant departments to determine the clearance method.
