Hazards and Protection.
Storage temp: ambient protect containers against physical damage.
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Wear appropriate protective gloves, clothing and goggles.
Wear positive pressure self-contained breathing apparatus (SCBA).
Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers.
200 C (decomp).
Flood with water. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible.
This material itself is non-combustible.
Can increase the intensity of fire.
Fire may produce irritating, corrosive and/or toxic gases.
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)
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.
Nausea, vomiting, diarrhea, and abdominal pain may develop.
Respiratory failure may occur if the paralysis affects the muscles of respiration. Dyspnea and bronchoconstriction have occurred after inhalation.
May cause severe burns.
Mydriasis may be present early in the course.
Induced vomiting is not advised because loss of protective airway reflexes may occur suddenly due to barium-induced paralysis.
Remove to fresh air.
Wash with copious amounts of water.
Flush with copious amounts of water for 15 min.
