Impurities/Additives: Product typically supplied in pure form; trace levels of moisture or acetic acid may occur depending on source and storage conditions
Inhalation: Remove person to fresh air, keep comfortable for breathing, seek immediate medical attention, provide oxygen if breathing is difficult
Skin Contact: Wash skin thoroughly with plenty of soap and water, remove contaminated clothing and shoes, seek medical attention if symptoms persist or irritation develops
Eye Contact: Rinse eyes cautiously with water for several minutes, remove contact lenses if present and easy to do, continue rinsing and seek medical evaluation
Ingestion: Rinse mouth, do not induce vomiting, never give anything by mouth to an unconscious person, call Poison Center or doctor immediately
Suitable Extinguishing Media: Water spray, dry chemical, foam, carbon dioxide
Specific Hazards: May emit toxic fumes including barium oxides and acetic acid vapors if involved in a fire, forming hazardous decomposition products
Protective Equipment: Firefighters use self-contained breathing apparatus and full protective gear
Special Procedures: Cool exposed containers with water spray, keep runoff water contained to prevent environmental contamination
Personal Precautions: Prevent skin and eye contact, use respiratory protection to avoid inhalation, ensure adequate ventilation
Protective Equipment: Chemical-resistant gloves, goggles, laboratory coat or chemical suit, particulate respirator
Spill Cleanup Methods: Shovel or sweep up material and place in suitable disposal container, avoid generating dusty conditions, wash spill site with soap and water after material pickup
Environmental Precautions: Prevent material from entering drains, surface or groundwater, alert authorities if contamination occurs on land or in waterways
Handling: Always work in well-ventilated areas, keep away from heat and sources of ignition, minimize generation of dust, thoroughly clean hands and face after handling, don’t eat, drink, or smoke around the material
Storage: Store in tightly closed containers, use dry and cool storage lockers, protect from moisture and incompatible substances such as acids or oxidizers, store away from food and beverage items, label containers clearly and check regularly for leaks or residue
Exposure Limits: OSHA PEL and ACGIH TLV for soluble barium compounds: 0.5 mg/m3 (as Ba)
Engineering Controls: Local exhaust ventilation and containment recommended, safety showers and eye wash stations available
Individual Protection: Impervious gloves (nitrile or PVC), chemical safety goggles, laboratory coat or apron, appropriate respiratory protection when dust or aerosols may form
Hygiene Measures: Wash skin after exposure, remove contaminated clothing, avoid cross contamination

Acute Toxicity: Oral LD50 (rat) 920 mg/kg, highly toxic by ingestion and inhalation, may cause severe or fatal poisoning
Effects: Vomiting, diarrhea, muscle paralysis, cardiac arrhythmia, respiratory distress, neurological impairment, potentially life-threatening hypokalemia
Chronic Effects: Long-term exposure may cause cumulative toxicity, kidney and liver dysfunction
Symptoms: Nausea, abdominal pain, muscle weakness, confusion, convulsions
Aquatic Toxicity: Extremely toxic to aquatic organisms due to barium ions, risk of serious environmental damage from large releases
Persistence & Degradability: Inorganic salt, not subject to biodegradation
Bioaccumulation: Barium compounds may accumulate in aquatic organisms, long-term hazard to food chain and wildlife
Mobility in Soil: Readily dissolves in water, can contaminate groundwater and persist in soil for lengthy periods
Other Effects: Hazard for drinking water supplies, specifically impacts invertebrates and fish at low concentrations
Waste Disposal: Treat as hazardous waste, follow local, national, or regional regulations for disposal, do not release to environment, contact licensed chemical waste disposal company
Container Disposal: Triple rinse and puncture containers before landfilling or recycling where permitted, never reuse chemical containers for household purposes
