Storage precautions for lithium hydride: 

Store in a cool and ventilated warehouse. Stay away from sparks and heat sources. Maintain relative humidity below 75%. The packaging requires sealing and must not come into contact with air. It should be stored separately from oxidants, acids, alcohols, etc., and should not be stored together. Adopting explosion-proof lighting and ventilation facilities.

Hazardous characteristics of lithium hydride:

Chemical reactivity is very high, exposed to air can spontaneously combustion. 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.

Lithium hydride storage considerations:

Store in a cool, ventilated warehouse. Stay away from the fire and heat sources. The relative humidity was kept below 75%. Packaging shall be sealed and shall not be in contact with the air. Should be stored separately from oxidants, acids, alcohols, etc., and 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.

Emergency treatment of lithium hydride:

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.
