LlTHIUMALUMJNUMHYDRIDE 237

concentrations cause asphyxiation; General Treatment for Exposure: Remove victim to open air. If he
is overcome by gas, apply artificial respiration. Guard against self-injury if confused; Toxicity by Inhu-
lation (Threshold Limit Value): 1000 ppm; Short-Tern Inhalation Limits: Data not available; Toxicity
by Ingestion: Not pertinent; Late Toxicity: None; Vapor (Gas) Irritant Characteristics: Vapors are
nonirritating to the eyes and throat; Lipid or Solid Irritant Characteristics: No appreciable hazard.
Practically harmless to the skin because it is very volatile and evaporates quickly. May cause frostbite;
Odor i'hreshold 5000-20,000 ppm.
Fire Hazards - Flash Point (deg. F): Propane: -156 CC; butane: -76 CC; Flammable Limits in Air (46):
Propane: 2.2 - 9.5; butane: 1.8 - 8.4; Fire Extinguishing Agents: Allow to burn while cooling adjacent
equipment with water spray. Extinguish small fires with dry chemical. Shut off leak if possible; Fire
Extinguishing Agents Not To Be Used: Water (let fire bum); Special Hazards of Combustion Products:
Not pertinent; Behavior in Fire: Containers may explode. Vapor is heavier than air and may travel a
long distance to a source of ignition and flash back; Ignition Temperature : No data; Electrical Hazard:
No data; Burning Rate: No data.
Chemical Reactivity - Reactivity with Water: No reaction; Reactivity with Common Materials: No
reaction; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent;
Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.

(delayed). Inhalation or ingestion causes abdominal pain (lead colic), metallic taste in mouth, loss of
weight, pain in muscles, and muscular weakness. Dust may irritate eyes; General Treatment for
Exposure: Consult physician after ingestion or exposure to high concentrations of dust. INGESTION:
call physician at once; as first aid, induce vomiting and give milk and magnesium sulfate (Epsom salt);
Toxicity by Znhalation (Threshold Limit Value): 0.2 mglm3; Short-Tern Inhalation Limits: Data not
available; Toxicity by Ingestion: Data not available; Late Toxicity: Impairs development of human fetal
connective tissue cells; Vapor (Gas) Irritant Characteristics: Not pertinent; Liquid or Solid Im'tant
Characteristics: Data not available; Odor Threshold Not pertinent.
