Health Hazards Information - Recommended Personal Protective Equipment: Data not available;
Symptoms Following Etposure: Very large doses are followed promptly by vomiting, due to local
gastric irritation; delayed emesis of diarrhea may occur. With smaller doses, symptoms usually appear
2-3 hours after ingestion. These include tingling of lips, tongue and face; malaise, head ache, sore
throat, fatigue, coarse tremors of neck, head and eye lids; apprehension, ataxia and confusion.
Convulsions may alternate with periods of coma and partial paralysis. Vital signs are essentially
normal, but in severe poisoning the pulse may be irregular and abnormally slow; ventricular fibrillation
and sudden death may occur at any time during acute phase . Pulmonary edema usually indicates
solvent intoxication; General Treatment for Exposure: INGESTION; treatment should be done by a
physician. In usually includes gastric lavage and administration of saline cathartic; phenobarbital, and
parenteral fluids. Patient should be kept quiet and under observation for at least 24 hours; Toxicity by
Inhalation Freshold Limit Value) : Not pertinent; Short-Tenn Exposure Limits: Not pertinent; Toxicity
by Ingestion: Grade 3; LD,, 50 to 500 mg/kg (rat); Late Toxicity: Data not available; Vapor (Gas)

spilled on clothing and allowed to remain, may cause smarting and reddening of the skin; Odor
Threshold Not pertinent.
Fire Hazards - Flash Point (deg. F): 162 - 171 CC; Flammable Limits in Air (%): Not pertinent; Fire
Extinguishing Agents: Water, foam, dry chemical or carbon dioxide; Fire Extinguishing Agents Not to
be Used: Not pertinent; special Hazards of Combustion Products: Toxic and irritating gases may be
generated; Behavior in Fire: Melts and burns; Ignition Temperature : Data not available; Electrical

Health Hazards Information -Recommended Personal Protective Equipment: Self-contained breathing
apparatus or positivepressure hose mask; rubber-boots or overshoes; clothing made of material
resistant to decaborane; rubber gloves; chemical-type goggles or face shield; Symptoms Following
Exposure: (The onset of symptoms is frequently delayed until one or two days after exposure.)
Inhalation or ingestion causes headache, nausea, light heatedness, drowsiness, nervousness, lack of
coordination, and tremor; muscle spasms and generalized convulsions may occur. Dust irritates eyes
and skin and may give same systemic symptoms as for inhalation if left on skin; General Treatment for
Exposure: Get medical attention after all exposures to this compound. Symptoms may be delayed for
48 hours. INHALATION: move patient to fresh air; keep him warm and quiet. EYES: flush with water
for at least 15 min. SKIN: immediately wash with soap and plenty of water. INGESTION: if victim
is conscious, give a tablespoonful of salt in a glass of warm water and repeat until vomit is clear. Note
to physician: Treat symptomatically; administration of methacarbamol or other muscle relaxant may
