Hazards and Protection.
Storage
Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.
Handling
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.
Protection
Wear appropriate protective gloves, clothing and goggles.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks
ELIMINATE all ignition sources. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. DO NOT GET WATER INSIDE CONTAINERS.
Stability
No data.

Fire.
Fire fighting
Extinguish using agent most appropriate for surrounding fire.
Fire potential
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.
Hazards
Contact with metals may evolve flammable hydrogen gas.
Combustion products
Fire may produce irritating, corrosive and/or toxic gases.

Health.
Exposure effects
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
Contact with molten substance may cause severe burns to skin and eyes. See Inhalation.
   Eyes
See Inhalation.

First aid
 
   Ingestion
Induced vomiting is not advised because loss of protective airway reflexes may occur suddenly due to barium-induced paralysis.
   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
Immediately flush with running water for at least 20 minutes.
