Environmental Hazard: Harmful to aquatic life with long lasting effects
Substance: Barium Carbonate
Percentage: ≥99%
Impurities: Strontium compounds, sulfates, calcium carbonate in trace amounts
Inhalation: Move the affected person into fresh air, keep at rest, call for immediate medical help
Skin Contact: Remove contaminated clothing and wash skin thoroughly with water and soap
Eye Contact: Flush eyes gently but thoroughly with water for at least 15 minutes, seek medical advice if irritation persists
Ingestion: Do not induce vomiting, rinse mouth with water, give 1–2 glasses of water to dilute, obtain urgent medical attention
Medical Assistance: Monitor vital signs, administer oxygen or artificial respiration if necessary, treat symptomatically for barium poisoning
Suitable Extinguishing Media: Use water spray, dry chemical powder, carbon dioxide, foam depending on surrounding fire
Unsuitable Extinguishing Media: Avoid high pressure water jets likely to spread material
Fire Hazards: Barium carbonate itself does not burn, no hazardous combustion products expected, fire can produce irritating or toxic fumes
Protective Equipment: Firefighters should wear self-contained breathing apparatus and protective clothing
Special Information: Use appropriate measures against nearby chemical or fuel fires, prevent runoff to sewers or waterways
Personal Precautions: Shut off sources of ignition, wear full protective clothing, gloves, eye and face protection; avoid breathing dust
Environmental Precautions: Prevent further leakage, spill or entry into drains, soil, or water systems, collect spillage
Cleanup Methods: Sweep up or vacuum spilled material carefully to avoid creating dust, place in secure containers for disposal
Decontamination: Ventilate area, wash spill site after material pickup is complete
Handling: Avoid dust generation, use in well-ventilated places, wash hands and face thoroughly before eating, drinking or smoking, utilize protective equipment
Storage: Store locked up in a dry, cool, and well-ventilated area, in tightly closed containers, away from acids and incompatible chemicals
Special Precautions: Segregate from foods, feedstuffs, and potable water; maintain clean working conditions; use only non-sparking tools in storage or handling
Occupational Exposure Limits: OSHA PEL (as soluble Ba compounds): 0.5 mg/m³ (TWA), ACGIH TLV: 0.5 mg/m³
Engineering Controls: Use process enclosures, local exhaust ventilation, minimize airborne concentration
Personal Protection: Wear chemical-resistant gloves, safety goggles or face shield, long-sleeved protective clothing; use approved respirator in dusty conditions
Hygiene Measures: Prohibit eating or drinking at work, wash thoroughly after handling, regularly clean personal protective equipment
