SECTION 4: First aid measures
Description of necessary first-aid measures
Fresh air, rest. Half-upright position. No mouth-to-mouth artificial respiration. Refer immediately for medical attention.
Remove contaminated clothes. Put clothes in sealable container. Rinse skin with plenty of water or shower. Refer immediately for medical attention .
Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer immediately for medical attention.
Rinse mouth. Do NOT induce vomiting. Refer immediately for medical attention.
Most important symptoms/effects, acute and delayed
This material is relatively toxic to people. It is more likely to cause irritation of skin and mucous membrane tissues rather than death. Its effects are primarily acute. A massive exposure to the eyes and by inhalation may be lethal. Those experiencing any ailment of the upper respiratory tract (e.g., bronchitis or pneumonia) are at a greater risk. (EPA, 1998)
Indication of immediate medical attention and special treatment needed, if necessary
Basic treatment: Establish a patent airway (oropharyngeal or nasopharyngeal airway, if needed). Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for pulmonary edema and treat if necessary ... Monitor for shock and treat if necessary ... Anticipate seizures and treat if necessary ... For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with 0.9% saline (NS) during treatment ... Do not use emetics. For ingestion, rinse mouth and administer 5 ml/kg up to 200 ml of water for dilution if the patient can swallow, has a strong gag reflex, and does not drool ... Cover skin burns with dry sterile dressings after decontamination ... Lithium and related compounds
SECTION 5: Firefighting measures
Suitable extinguishing media
Use approved Class D extinguishers or smother with dry sand, dry clay, or dry ground limestone. Do not use carbon dioxide or halogenated extinguishing agents. Do NOT use water. Violent reaction may result.
Specific hazards arising from the chemical
In a fire, irritating alkali fumes may form. Lithium hydride can form airborne dust clouds which may explode on contact with flame, heat, or oxidizing materials. Additionally, spontaneous ignition occurs when nitrous oxide and lithium hydride are mixed. Lithium hydride also forms explosive mixtures with liquid oxygen. Contact with heat, moisture or acid causes exothermic reaction and evolution of hydrogen as well as lithium hydroxide. Incompatible with air and moisture, nitrous oxide, strong oxidizers, and liquid oxygen. Lithium hydride may ignite spontaneously in air and should be maintained and handled out of contact with air and moisture. Any contact with nitrous oxide; airborne powders may ignite upon reaching moisture. (EPA, 1998)
Special protective actions for fire-fighters
NO hydrous agents, foam, carbon dioxide. Use inert gas, dry sand, special powder.
SECTION 6: Accidental release measures
Personal precautions, protective equipment and emergency procedures
Evacuate danger area! Consult an expert! Personal protection: chemical protection suit including self-contained breathing apparatus. Cover the spilled material with dry powder.
Environmental precautions
Evacuate danger area! Consult an expert! Personal protection: chemical protection suit including self-contained breathing apparatus. Cover the spilled material with dry powder.
Methods and materials for containment and cleaning up
Wearing butyl rubber gloves, fireproof clothing, face shield and goggles, cover spill with sand. Transfer mixture into a dry plastic bag filled in advance with an inert gas. Carry outdoors for incineration. After burning (if not in a proper incinerator), sprinkle water on the residue for complete destruction. Alternatively, in the fume hood, add butanol slowly to the solid mixture until the reaction ceases. Then carefully add water until all the hydride is destroyed. Let stand until solid settles.
SECTION 7: Handling and storage
Precautions for safe handling
NO open flames. See Chemical Dangers. Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Conditions for safe storage, including any incompatibilities
Separated from incompatible materials. See Chemical Dangers. Dry. Keep under mineral oil or inert gas. Cool. Store in an area without drain or sewer access.Store in a cool, dry, well-ventilated location. Must be stored in a dry location. Immediately remove and properly dispose of any spilled material.

SECTION 10: Stability and reactivity
Reactivity
Decomposes on contact with hot surfaces or flames. This produces irritating alkali fumes. The substance may ignite spontaneously on contact with moist air. The substance is a strong reducing agent. Reacts violently with oxidants, halogenated hydrocarbons and acids. This produces flammable/explosive gas (hydrogen - see ICSC 0001). Reacts violently with water. This produces corrosive fumes of lithium hydroxide.
Chemical stability
Darkens rapidly on exposure to light.
Possibility of hazardous reactions
Lithium hydride is a flammable solid and is dangerous when wet.Dust explosion possible if in powder or granular form, mixed with air.LITHIUM HYDRIDE is a strong reducing agent. Th esolid may decompose violently in contact with most oxidizing materials. It reacts exothermically with water to form caustic lithium hydroxide and hydrogen gas; the hydrogen may ignite. May ignite spontaneously in moist air. Mixtures with liquid oxygen are explosive. Ignites on contact with dinitrogen oxide [Mellor, 1967, vol. 8, suppl. 2.2, p. 214].
