Product Name: Argon
Chemical Formula: Ar
Synonyms: None
CAS Number: 7440-37-1
Recommended Use: Shielding gas during welding, inerting processes, analytical research applications, filling gas for light bulbs, manufacturing of electronics
Supplier: Industrial gas providers, chemical distribution companies, laboratory suppliers
Emergency Phone: Supplier-specific emergency phone line, typically found on label or order documentation
GHS Classification: Gas under pressure, Liquefied gas
Hazard Statements: Contains gas under pressure; may explode if heated
Precautionary Statements: Store away from heat sources, handle cylinders carefully to prevent release
Main Hazards: Asphyxiation in confined spaces, rapid release can cause frostbite, high pressure fire or rupture risk
Pictograms: Gas cylinder symbol according to GHS
NFPA Ratings: Health: 0, Flammability: 0, Instability: 0
OSHA Label: Nonflammable compressed gas
Substance: Pure Argon
Concentration: 99.99% to 100%
Impurities: Rare trace gases (nitrogen, oxygen) possible depending on grade
EC Number: 231-147-0
Molecular Weight: 39.95 g/mol
Inhalation: Move person to fresh air immediately if breathing difficulty occurs, administer oxygen if breathing is difficult, perform CPR if breathing has stopped, call emergency medical services without delay
Skin Contact: Remove any clothing that may be chilled by contact with liquefied argon, flush area with tepid water, seek medical attention for frostbite or skin damage
Eye Contact: In the event of liquid spray to eyes, rinse thoroughly with running water keeping lids open, seek urgent medical attention
Ingestion: Not a route of exposure for gases
Most important symptoms/effects: Headache, dizziness, shortness of breath, unconsciousness in poorly ventilated spaces
Protection for First Aiders: Responders must use self-contained breathing equipment if argon has displaced oxygen in the environment
Suitable Extinguishing Media: Argon itself does not burn, use fire-fighting measures for surrounding materials
Specific Hazards: Cylinders may rupture or burst from heat, high pressure release can create projectile hazard
Protective Equipment: Self-contained breathing apparatus and full protective gear for fire fighters working in argon-filled or oxygen-poor atmospheres
Firefighting Procedures: Remove unaffected cylinders from area if safe, cool exposed containers with water, do not use water jets directly on leak
Hazardous Combustion Products: None resulting from argon
Personal Precautions: Evacuate area, ventilate space well, ensure adequate oxygen is present, restrict unprotected personnel from entering
Protective Equipment: Use self-contained breathing apparatus if entering an area with potential oxygen deficiency
Environmental Precautions: Prevent entry into confined spaces, pits, basements where gas can displace air
Cleanup Methods: Ventilate with fresh air, stop leak if it can be done safely, check for oxygen presence before allowing re-entry
Response Team: Only trained personnel should work with major releases of pressurized gases
Precautions for Safe Handling: Use only in adequately ventilated areas, avoid inhalation or contact with cold gas or liquefied product, never drop or handle cylinders roughly
Safe Storage Conditions: Store upright, secure cylinders to wall or special racks, keep away from heat sources or direct sunlight, separate full cylinders from empties
Prohibited Practices: Do not tamper with cylinder value or safety relief, do not attempt to refill cylinders yourself
Handling Equipment: Use proper trolleys for cylinders, fit correct regulators
Exposure Limits: Argon is not classified as hazardous and does not have a workplace exposure limit, but always ensure oxygen remains above 19.5% volume in work area
Engineering Controls: Ventilation systems and local exhaust, monitoring of oxygen levels in closed or confined spaces
Personal Protection Equipment: Safety goggles, insulated gloves if handling liquefied argon, safety shoes for cylinder movement
Respiratory Protection: Not typically required in open or ventilated areas, but self-contained breathing apparatus for oxygen-deficient environments is critical

Critical Temperature: -122.3°C
Critical Pressure: 48.0 atm
Chemical Stability: Remains stable under normal storage and usage conditions
Explosive Properties: None
Conditions to Avoid: Strong heat sources, confined non-ventilated spaces
Incompatible Materials: None known under ambient conditions; does not react with most substances
Hazardous Decomposition Products: None
Acute Toxicity: Non-toxic by inhalation at low concentrations, risk of asphyxia at elevated concentrations
Chronic Effects: No evidence of long-term health effects in humans
Local Effects: Direct contact with liquefied argon can freeze tissue, producing frostbite
Inhalation Risk: Asphyxiation can occur if oxygen concentrations are significantly reduced
Symptoms of Overexposure: Dizziness, fatigue, nausea, loss of consciousness
Routes of Exposure: Inhalation
Environmental Impact: Does not bioaccumulate, no known toxic effects on aquatic or terrestrial organisms
Persistence and Degradability: Naturally abundant in the atmosphere, disperses rapidly
Biodegradability: Not applicable for inert gases
Mobility in Soil: Not relevant, diffuses naturally in air
Disposal Methods: Release contents slowly in an outdoor or well-ventilated area, recycle empty cylinders according to supplier’s instructions
Contaminated Packaging: Return cylinders to supplier for reuse or proper recycling
Environmental Precautions: Ensure gas is not released into confined or poorly ventilated spaces
