SECTION 2: Composition and Information on Ingredients
Ingredient CAS Number Percent ACGIH (TWA) OSHA (PEL)
Title Compound 513-77-9 100 0.5mg/m3 (as Ba) 0.5mg/m3 (as Ba)
SECTION 3: Hazards Identification
Emergency Overview: Harmful if swallowed.
Primary Routes of Exposure: Ingestion
Eye Contact: May cause slight to mild irritation of the eyes.
Skin Contact: May cause slight to mild irritation of the skin.
Inhalation: May cause difficulty in breathing, tightness of the muscles of the face and neck.
Ingestion: Ingestion may cause vomiting, irregular heartbeat, pain, tremors, convulsions, and cardiac arrest.
Acute Health Effects: Harmful if swallowed. Barium forms a protein adduct in serum and is deposited in bone.
Chronic Health Effects: Long term exposure to dust may cause baritosis, a benign pneumoconiosis. Possible risk of impaired fertility.
NTP: No
IARC: No
OSHA: No
SECTION 4: First Aid Measures
Eye Exposure: Immediately flush the eyes with copious amounts of water for at least 10-15 minutes. A victim may need assistance in keeping their eye lids open. Get immediate medical attention.
Skin Exposure: Wash the affected area with water. Remove contaminated clothes if necessary. Seek medical assistance if irritation persists.
Inhalation: Remove the victim to fresh air. Closely monitor the victim for signs of respiratory problems, such as difficulty in breathing, coughing, wheezing, or pain. In such cases seek immediate medical assistance.
Ingestion: Seek medical attention immediately. Keep the victim calm. Give the victim water (only if conscious). Induce vomiting only if directed by medical personnel.
SECTION 5: Fire Fighting Measures
Flash Point: not applicable
Autoignition Temperature: none
Explosion Limits: none
Extinguishing Medium: none required
Special Fire Fighting Procedures: If involved in a fire, fire fighters should be equipped with a NIOSH approved positive pressure self-contained breathing apparatus and full protective clothing.

Unusual Fire or Explosion Hazards: No unusual fire or explosion hazards.
SECTION 6: Accidental Release Measures
Spill and Leak Procedures: Small spills can be mixed with powdered sodium carbonate or ground limestone and swept up.
SECTION 7: Handling and Storage
Handling and Storage: Store material in a tightly sealed bottle away from moisture.
SECTION 8: Exposure Controls and Personal Protection
Eye Protection: Always wear approved safety glasses when handling a chemical substance in the laboratory.
Skin Protection: Wear appropriate chemical resistant gloves and protective clothing.
Ventilation: If possible, handle the material in an efficient fume hood.
Respirator: In the absence of adequate ventilation a respirator should be worn. The use of a respiratory requires a Respirator Protection Program to be in compliance with 29 CFR 1910.134.
Additional Protection: No additional protection required.
