Other Components: Trace impurities may be present depending on source
Molecular Weight: 261.34 g/mol
Relevant Impurities: May include small amounts of insolubles or contaminants from processing environment
Inhalation: Move affected person to fresh air, support breathing if needed, give medical attention immediately
Ingestion: Rinse mouth, never induce vomiting, provide water if patient is conscious, seek urgent medical advice
Skin Contact: Remove contaminated clothing, wash with plenty of soap and water, medical help if irritation develops
Eye Contact: Rinse cautiously with water for several minutes, lift eyelids if needed, remove contact lenses, seek medical help
Acute Symptoms: Convulsions, nausea, dizziness, muscle twitching possible after significant exposure
Medical Attention: Always required after ingestion or severe exposure; symptomatic and supportive treatment
Flammability: Not combustible but supports fire by releasing oxygen
Suitable Extinguishing Media: Water spray, dry chemical, avoid dry combustibles for large loads
Unsuitable Media: Foam, carbon dioxide (ineffective against oxidizer)
Specific Hazards: Releases toxic nitrogen oxides, barium fumes under fire
Protective Equipment: Full self-contained breathing apparatus, protective clothing against chemicals
Explosive Sensitivity: Intense heat may cause rupture of sealed containers or severe oxidizing incidents
Additional Info: Cool containers exposed to flames with water spray, avoid direct contact with spill runoff
Personal Precautions: Remove all sources of combustion, evacuate uninvolved individuals, ventilate area
Environmental Precautions: Prevent entry into drains, waterways, and soil; notify authorities in case of significant discharge
Method for Clean Up: Wear full PPE, use dry cleanup methods such as vacuum or shovel into suitable containers, avoid generating dust
Waste Disposal: Place waste in appropriate sealed containers, label clearly, coordinate with licensed disposal contractor
Decontamination: Rinse spill area thoroughly with water once dry material is removed
Handling: Always handle in chemical fume hood or well-ventilated area; avoid contact with reducing agents, acids, organic materials
Hygiene Measures: Wash hands before eating or drinking, remove contaminated clothing, avoid smoking during use
Storage: Store in cool, dry location; keep containers tightly closed; segregate from combustibles, strong acids, and reducing materials
Incompatibilities: Strong acids, organic materials, finely divided metals, reducing agents
Packaging: Use certified, airtight containers clearly labeled for oxidizers, protect from physical damage
Storage Temperature: Keep below 30°C, avoid conditions of high temperature and humidity
Exposure Limits: OSHA PEL: 0.5 mg/m³ (barium, soluble compounds as Ba), ACGIH TLV: 0.5 mg/m³
Engineering Controls: Local exhaust ventilation, safety shower, and eye wash stations in working areas
Personal Protection: NIOSH/MSHA approved respirator, chemical resistant gloves (nitrile or neoprene), goggles, lab coat or coveralls
Environmental Controls: Use double containment if risk of spill, maintain clean workspace, monitor air regularly
Hygiene: Change out of clothing promptly after handling, launder contaminated garments before reuse

Reactivity: Strong oxidizer, reacts with reducing agents and organic materials with risk of fire or explosion
Incompatible Materials: Combustibles, acids, ammonium salts, metal powders
Hazardous Decomposition Products: Nitrogen oxides, barium oxide, toxic metal vapors
Conditions to Avoid: Heating above melting, moisture, contact with incompatible materials
Polymerization: Will not occur
Acute Toxicity: Oral LD50: 355 mg/kg (rat)
Inhalation: Inhaled dust causes severe respiratory tract irritation, coughing, and systemic toxicity
Skin: Prolonged or repeated exposure can cause irritation, redness, absorption possible with toxicity symptoms
Eyes: Irritates mucous membranes, severe overexposure may cause lasting damage
Chronic Exposure: Can affect nervous system, cardiovascular system, muscles; repeated exposure increases risk of barium poisoning
Sensitization: Reports of skin or respiratory sensitization rare
Carcinogenicity: Not listed as carcinogen by IARC, NTP, OSHA
Mutagenicity: Evidence unavailable for mutagenic effects
Environmental Toxicity: Very toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment
Persistence: Low biodegradability; persists in aquatic media and sediments
Bioaccumulation Potential: Moderate, especially in organisms living in contaminated water
Mobility: Barium ions mobile in water systems, can migrate into groundwater
Soil Impact: Disrupts soil organism health, reduces nutrient cycling capability of affected soils
Degradation: Not subject to natural breakdown over reasonable time scales
Special Note: Avoid discharge into surface and groundwater during use or disposal
Waste Disposal: Collect in sealed, clearly labeled containers for hazardous waste; handle as per local and national regulations
Contaminated Packaging: Empty containers retain hazard, treat as material itself
Methods: Incineration at licensed facility, deep burial at approved landfill if permitted by local authority
Do Not: Flush to drain, dispose with regular garbage, dump on land
Recycling: Not typically recoverable for reuse due to toxicity risks
Consult: Local environmental, health, and safety authorities for guidance
