May cause poisoning, vomiting, colic, diarrhea, slow irregular pulse, transient hypertension convulsions, tremors, muscular paralysis, and acute barium poisoning. Chronic exposure may cause chronic barium poisoning.
   Inhalation
May cause respiratory irritation, dizziness, nausea, vomiting, colic, diarrhea, rapid respiration, high blood pressure, irregular heart action, convulsions, paralysis and acute barium poisoning. Chronic exposure may cause pulmonary granulomas and chronic barium poisoning.
   Skin
May cause irritation, dermatitis.

If conscious, give 1-2 glasses of milk or water and induce vomiting, seek medical attention. Never give anything by mouth or induce vomiting on an unconscious person.
   Inhalation
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult.
   Skin
Remove and isolate contaminated clothing and shoes. Immediately flush with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin.
   Eyes
