Inhalation: Remove any exposed person to fresh air, support breathing if required, and seek immediate medical attention if symptoms like coughing, breathing difficulty, or dizziness appear
Ingestion: Do not induce vomiting, never try to give anything by mouth to an unconscious person, and seek medical assistance right away; possible gastric lavage in a medical setting
Skin Contact: Remove contaminated clothing, wash skin immediately with soap and water for at least fifteen minutes; seek medical attention for persistent irritation or burns
Eye Contact: Rinse eyes gently for at least fifteen minutes with clean running water, keep eyelids open and remove any contact lenses, seek prompt medical evaluation
Advice for Physicians: Treat poisoning symptomatically, monitor for barium toxicity, address electrolyte imbalance if ingestion has occurred
Extinguishing Media: CO2, dry chemical powder, foam, do not use water directly on the burning material
Hazards from Combustion: Formation of toxic fumes, such as barium oxides, carbon monoxide, and carbon dioxide can occur in extreme heat or fire situations
Special Equipment for Firefighters: Use self-contained breathing apparatus and full protective gear
Firefighting Instructions: Evacuate the area and contain runoff; avoid inhalation of fumes or combustion products
Explosion Risk: May emit flammable vapors under high temperatures, risk increases if mixed with incompatible materials
Personal Precautions: Evacuate unnecessary personnel, wear appropriate protective equipment including gloves, eye protection, and respirator, avoid inhalation or direct contact
Environmental Precautions: Prevent further leakage or spillage, avoid discharge into waterways, soil, and drains
Containment Methods: Dike area with inert absorbent material, such as sand or earth; do not permit entry into sewers or public waterways
Cleanup Methods: Scoop up absorbed material into suitable chemical waste containers for disposal, ventilate area, and decontaminate surfaces with water and detergent
Safe Handling Tips: Use only with proper ventilation and personal protective equipment, handle with care to avoid spills, never eat or drink in work area, wash hands thoroughly after use
Storage Conditions: Store in tightly sealed containers, place in a dry, cool, well-ventilated area away from incompatible substances such as strong acids and oxidizers, keep away from food and animal feed
Containers: Use appropriate, corrosion-resistant packaging; inspect containers regularly for leaks
Incompatible Materials: Strong acids, oxidizing agents
Other Precautions: Restrict access to authorized personnel, provide proper signage and training to anyone handling the compound
Occupational Exposure Limit: OSHA PEL for soluble barium compounds: 0.5 mg/m3 (as Ba), ACGIH TLV: 0.5 mg/m3 (as Ba)
Engineering Controls: Use local exhaust ventilation to minimize vapor and mist; safety showers and eyewash stations should be easily accessible
Personal Protection: Chemical-resistant gloves (nitrile or similar), safety goggles with side shields, long-sleeved protective clothing, and a respirator with an approved filter for organic vapors and particulates
Hygiene Measures: Remove contaminated clothing promptly, wash exposed areas with soap, separate work and eating areas, prohibit smoking in storage and use zones
Environmental Controls: Capture and properly treat exhaust before atmospheric release; containment systems for all transfer and handling operations

Chemical Stability: Maintains stability under normal storage and handling conditions, breaks down with strong heat and incompatible chemicals
Possibility of Hazardous Reactions: Reaction risk with acids, producing flammable hydrogen gas and toxic barium salts
Conditions to Avoid: Strong heat, direct sunlight, excessive moisture, contact with oxidizers or acids

Acute Toxicity: Oral LD50 (rat): estimated between 50–500 mg/kg (as barium compound), much lower with direct ingestion
Routes of Exposure: Ingestion, inhalation, skin, and eye contact
Symptoms: Abdominal pain, headache, muscle weakness, vomiting, cramps; skin and eye redness or burns from direct contact; pulmonary issues if inhaled
Chronic Effects: Prolonged exposure may cause kidney, liver, and central nervous system effects due to bioaccumulation of barium
Carcinogenicity: Not classified as a human carcinogen by IARC, NTP, or OSHA
Other Health Effects: Risk of sensitization; possible aggravation of pre-existing skin, respiratory, or cardiovascular conditions
Exposure Limits: See exposure control section
Toxicity to Aquatic Life: Acute toxicity to fish and invertebrates, LC50 values for aquatic species generally below 1 mg/L
Persistence and Degradability: Organometallic barium compounds persist in soil and sediments, naphthenic acids degrade slowly, contributing to long-term aquatic and terrestrial risks
Bioaccumulation: Barium builds up in aquatic organisms and may move up food chains, posing hazards to wildlife
Mobility in Soil: Moderately mobile, with potential to reach groundwater depending on local soil chemistry
Other Adverse Effects: Ongoing aquatic ecosystem disruption, probable long-term negative impact on sediment quality and biodiversity
Waste Treatment Methods: Treat as hazardous waste under RCRA and local rules, consult regulatory authority for specialized disposal
Container Disposal: Rinse thoroughly, do not reuse, dispose of as hazardous material
Precautions: Do not drain or wash into sewers; avoid open dumping or incineration without emission controls
