Health Hazards Information - Recommended Personal Protective Equipment: Goggles or face shield;
dust respirator; rubber gloves and shoes; suitable coveralls; Symptoms Following wosure: Inhalation
or contact with eyes or skin causes irritation. Ingestion causes excessive salivation, vomiting, colic,
diarrhea, convulsive tremors, slow, hard pulse, elevated blood pressure. Hemorrhages may occur in
the stomach, intestines, and kidneys, Muscular paralysis may follow; General Treatment for Exposure:
Get medical attention. Alert doctor to possibility of barium poisoning, particularly if compound was
swallowed. Inhalation: remove to fresh air. Eyes: flush with water for at least 15 min. Skin: flush with
water. Ingestion: oral administration of a aqueous 10% solution of magnesium or sodium sulfate; in
severe intoxication, calcium or magnesium salt may have to be given iv with caution; treatment
otherwise is supportive and symptomatic; Toxicity by Inhalation (Threshold Limit Value) : 0.5 mg/m3;

Fire Hazards - Flash Point: Not flammable but can aggravate fires; Flammable Limits in Air (%): Not
flammable; Fire Extinguishing Agents: Not pertinent; Fire Extinguishing Agents Not To Be Used Not
pertinent; Special Hazards of Combustion Products: Produces toxic gaseous oxides of nitrogen when
involved in fires; Behavior in Fire: Mixtures with combustible materials are readily ignited and bum
fiercely. Containers may explode; Ignition Temperature: Not pertinent; Electrical Hazard Not
pertinent; Burning Rate: Not pertinent.
Chemical Reactivity - Reactivity with Water: No reaction; Reactivity with Common Materials: Fire
can result by contact of this material with combustibles; Stability During Transport: Stable; Neutralizing
