NO open flames, NO sparks, and NO smoking. NO contact with flammable substances. NO contact with reducing agents. In case of fire in the surroundings: all extinguishing agents allowed. EXPLOSION Risk of fire and explosion on contact with combustible substances, reducing agents. In case of fire: cool drums, etc., by spraying with water but avoid contact of the substance with water. Combat fire from a sheltered position. EXPOSURE  •INHALATION Cough. Dizziness. Sore throat. See Notes. Fresh air, rest. Refer for medical attention.  •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 See Skin. Safety goggles, face shield. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Do not eat, drink, or smoke during work. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Ventilation. Remove all ignition sources. Do NOT absorb in saw-dust or other combustible absorbents. NEVER direct water jet on liquid. Fireproof. Separated from combustible and reducing substances. Cool. Special insulated container.

International Chemical Safety Cards OXYGEN (LIQUEFIED) ICSC: 0880 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: LIQUEFIED GAS. COLOURLESS TO BLUE EXTREMELY COLD LIQUID PHYSICAL DANGERS: The gas is heavier than air. CHEMICAL DANGERS: The substance is a strong oxidant and reacts with combustible and reducing materials causing fire and explosion hazard. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. MAK not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation. INHALATION RISK: EFFECTS OF SHORT-TERM EXPOSURE: Rapid evaporation of the liquid may cause frostbite. The substance at very high concentrations irritates the respiratory tract. The substance may cause effects on the central nervous system. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Boiling point: -183°C Melting point: -218.4°C Solubility in water, ml/100 ml at 20°C: 3.1 Vapour pressure, kPa at -118°C: 5080 Relative vapour density (air = 1): 1.43 Octanol/water partition coefficient as log Pow: 0.65 ENVIRONMENTAL DATA N O T E S Work clothes saturated with oxygen may be a serious fire hazard. Do NOT use in the vicinity of a fire or a hot surface, or during welding. Inhalation symptoms are characteristic of exposure to extremely high concentrations only. Also consult ICSC #0138 Oxygen.
