Product Name: Xenon
Chemical Formula: Xe
CAS Number: 7440-63-3
Recommended Use: Specialty applications in lighting, medical imaging, and research laboratories
Supplier Identification: Industrial gas suppliers, specialty chemical distributors
Contact Information: Emergency contact numbers provided by supplier, accessible 24/7
GHS Classification: Gases under pressure, Compressed gas, Liquefied gas
Signal Word: Warning
Hazard Statements: Contains gas under pressure; may explode if heated; asphyxiant in high concentrations
Precautionary Statements: Store in a well-ventilated place; avoid breathing concentrated vapors; use only outdoors or in well-ventilated areas
Main Hazards: Inert gas can displace oxygen, risk of suffocation in poorly ventilated spaces, cylinder rupture under thermal exposure
Chemical Identity: Xenon
Purity: Greater than 99.9% Xe
Synonyms: Elemental xenon, Micro Lascar gas
Impurities: None intentionally added, but trace rare gases possible from extraction process
Inhalation: Move person to fresh air, keep comfortable for breathing, administer oxygen if available, seek medical attention for symptoms like dizziness, headache, or shortness of breath
Skin Contact: No expected skin toxicity; handle cold/liquid phase with insulated gloves to prevent frostbite
Eye Contact: Rinse cautiously with water if foreign object contamination occurs, seek ophthalmologic advice for persistent discomfort
Ingestion: Not expected route of exposure; for any ingestion of liquefied xenon, do not induce vomiting and seek medical evaluation
Suitable Extinguishing Media: Xenon is non-flammable; use agents suitable for surrounding combustible materials
Specific Hazards: Gas under pressure — cylinder may rupture or explode when exposed to heat
Protective Equipment: Use self-contained breathing apparatus and full protective gear for firefighting near pressurized containers
Hazardous Combustion Products: None; xenon does not react to produce toxic combustion gases
Personal Precautions: Evacuate area, ventilate space, avoid entering areas where oxygen levels have been reduced
Protective Equipment: Use positive pressure air supply if local oxygen is suspected to be low
Environmental Precautions: Prevent buildup of gas in low-lying, enclosed areas
Spill Clean-Up Methods: Allow gas to disperse in open air, monitor oxygen concentration before re-entry, do not re-enter space until safe
Handling: Secure gas cylinders upright with chains or straps, open valves slowly, avoid rough handling or dropping cylinders, use regulator designed for inert gases
Storage: Store in a cool, dry, well-ventilated area away from direct sunlight or heat sources, segregate from flammable gases, ensure proper signage and access controls
Further Precautions: Keep away from incompatible material storage, especially oxidizers and materials sensitive to pressure
Occupational Exposure Limits: No established OSHA or ACGIH exposure limits for xenon; maintain adequate oxygen levels (>19.5%)
Engineering Controls: Local exhaust ventilation for confined or below-ground spaces prone to oxygen displacement
Personal Protective Equipment: Insulated gloves for liquefied product, safety glasses, industrial work shoes, for large-scale or enclosed tank work, use supplied-air respirator
Workplace Monitoring: Oxygen monitors recommended in all areas of use
Appearance: Colorless, odorless gas; may appear liquid under pressure/cryogenic temperatures
Molecular Weight: 131.29 g/mol
Boiling Point: -108.1°C (liquefied)
Melting Point: -111.8°C
Vapor Pressure: High under ambient conditions
Solubility: Slightly soluble in water, more soluble in organic solvents
Density: 5.86 kg/m³ at 0°C (gas)
Critical Temperature: 16.6°C
Odor Threshold: No characteristic odor
Reactivity: Chemically inert under normal conditions, does not react with air, water, or most chemicals
Chemical Stability: Stable in compressed or liquefied form under prescribed conditions
Conditions to Avoid: High temperature, improper handling of pressurized containers, mechanical impact
Incompatible Materials: None significant; highly inert gas
Hazardous Decomposition Products: None under normal storage and use
Acute Toxicity: Not toxic at atmospheric concentrations; high levels displace oxygen, leading to suffocation
Chronic Effects: No known chronic toxicity
Routes of Exposure: Inhalation is primary; direct contact unlikely to cause harm
Symptoms of Overexposure: Dizziness, headache, confusion, unconsciousness under oxygen-poor conditions
Environmental Effects: Inert gas, not expected to harm aquatic or terrestrial environments
Persistence and Degradability: Not persistent, disperses rapidly into atmosphere
Bioaccumulative Potential: Not bioaccumulative
Mobility in Soil: Highly volatile; does not accumulate in soil or water
Waste Treatment Methods: Vent gas outdoors in a safe, well-ventilated area to allow rapid atmospheric dispersion
Special Disposal Precautions: Do not release large amounts into enclosed spaces
Container Disposal: Return pressurized containers to supplier, do not puncture or incinerate cylinders
UN Number: UN2036 (compressed or liquefied xenon)
Proper Shipping Name: Xenon, compressed or Xenon, refrigerated liquid
Transport Hazard Class: Class 2.2 (non-flammable, non-toxic gases)
Packing Group: Not assigned
Label Requirements: Non-flammable gas, asphyxiant
Transport Considerations: Secure cylinders during transport, comply with national and international safety codes
Inventory Status: Listed in TSCA, DSL, EINECS and other major chemical inventories
Regulatory Classification: Not regulated as a hazardous substance under major US or EU chemical safety guidelines; regulated only for pressurized containment
Safety Data Reporting: Mandatory under OSHA Hazard Communication Standard for workplace use
Additional Standards: Compliance with local occupational health and environmental authorities, cylinder labeling, and training on oxygen-deficiency risks
