Health.
Exposure limit(s)
NIOSH REL*: TWA 0.5 mg/m3 OSHA PEL*: TWA 0.5 mg/m3 [*Note: REL and PEL also apply to other soluble barium compounds (as Ba) except Barium sulfate.] IDLH 50 mg/m3 (as Ba)
Exposure effects
Transient elevated blood pressure may develop soon after exposure. Profound abnormally low blood pressure and rapid heart rate may develop within hours of exposure in severe cases. Initial feelings of numbness and tingling occur around the mouth, face, and neck progressing to limb paralysis. This may progress to involve muscles of respiration. Speech is often lost or impaired as the tongue and pharynx are affected. Seizures may occur with acute intoxication.
   Ingestion
Nausea, vomiting, diarrhea, and abdominal pain may develop.
   Inhalation
Respiratory failure may occur if the paralysis affects the muscles of respiration. Dyspnea and bronchoconstriction have occurred after inhalation.
   Skin
May cause severe burns.
   Eyes
Mydriasis may be present early in the course.

First aid
 
   Ingestion
Induced vomiting is not advised because loss of protective airway reflexes may occur suddenly due to barium-induced paralysis.
   Inhalation
Remove to fresh air.
   Skin
Wash with copious amounts of water.
   Eyes
Flush with copious amounts of water for 15 min.
