Oxygen/Carbon Dioxide/Inert Gas Mixture

SECTION 2: Hazards identification

OSHA Emergency Overview WARNING! High-pressure, oxidizing gas. Vigorously accelerates combustion. Self-contained breathing apparatus may be required by rescue workers.

Principle Routes of Exposure

Inhalation. EFFECTS OF A SINGLE (ACUTE) OVEREXPOSURE: INHALATION: Breathing 80% or more oxygen at atmospheric pressure for more than a few hours may cause nasal stuffiness, cough, sore throat, chest pain and breathing difficulty. Breathing oxygen at higher pressure increases the likelihood of adverse effects within a shorter time period. Breathing pure oxygen under pressure may cause lung damage and also central nervous system effects resulting in dizziness, poor co-ordination, tingling sensation, visual and hearing disturbances, muscular twitching, unconsciousness and convulsions. Moderate concentrations may cause headache, drowsiness, dizziness, stinging of the nose and throat and rapid breathing. SKIN CONTACT: No evidence of adverse effects from available information. SKIN ABSORPTION: No evidence of adverse effects from available information. SWALLOWING: No evidence of adverse effects from available information. EYE CONTACT: No evidence of adverse effects from available information. EFFECTS OF REPEATED (CHRONIC) OVEREXPOSURE: No evidence of adverse effects from available information. OTHER EFFECTS OF OVEREXPOSURE: Damage to retinal ganglion cells and central nervous system may occur. See "Notes to Physician" in the "First Aid" Section.
