International Chemical Safety Cards XENON ICSC: 0609 Xe Atomic mass: 131.3 (cylinder) ICSC #    0609 CAS #     7440-63-3 RTECS # ZE1280000 UN #        2036 November 23, 2007 Validated TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Not combustible. Heating will cause rise in pressure with risk of bursting. In case of fire in the surroundings: use appropriate extinguishing media. EXPLOSION In case of fire: keep cylinder cool by spraying with water. EXPOSURE  •INHALATION Dizziness. Dullness. Headache. Suffocation. Ventilation. Fresh air, rest. Artificial respiration may be needed. Seek medical attention if you feel unwell  •SKIN ON CONTACT WITH LIQUID: FROSTBITE. Cold-insulating gloves. Protective clothing. ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer for medical attention.  •EYES ON CONTACT WITH LIQUID: FROSBITE. Safety goggles or face shield . Rinse with plenty of water (remove contact lenses if easily possible). Refer immediately for medical attention.  •INGESTION SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Personal protection: self-contained breathing apparatus. Ventilation. Fireproof if in building. Keep in a well-ventilated room. UN Hazard Class: 2.2 Signal: Warning Cylinder Contains gas under pressure; may explode if heated SEE IMPORTANT INFORMATION ON BACK ICSC: 0609 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities (C) IPCS CEC 1994. No modifications to the International version have been made except to add the OSHA PELs, NIOSH RELs and NIOSH IDLH values.

International Chemical Safety Cards XENON ICSC: 0609 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS, ODOURLESS, COMPRESSED LIQUEFIED GAS . PHYSICAL DANGERS: The gas is heavier than air and may accumulate in lowered spaces causing a deficiency of oxygen. CHEMICAL DANGERS: OCCUPATIONAL EXPOSURE LIMITS: TLV not established. MAK not established. ROUTES OF EXPOSURE: INHALATION RISK: On loss of containment this gas can cause suffocation by lowering the oxygen content of the air in confined areas. EFFECTS OF SHORT-TERM EXPOSURE: Suffocation. The liquid may cause frostbite. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Boiling point: -108.1°C Melting point: -111.8°C Solubility in water, g/100 ml at 20°C: 0.6 (very poor) Relative vapour density (air = 1): 4.5 Octanol/water partition coefficient as log Pow: 1.4 ENVIRONMENTAL DATA N O T E S High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death. Check oxygen content before entering area. Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
