Hazards Identification Emergency Overview WARNING! High pressure, oxidizing gas. Vigorously accelerates combustion. Self-contained breathing apparatus may be required by rescue workers. ROUTES OF EXPOSURE: THRESHOLD LIMIT VALUE: TLV-TWA Data from 2007 Guide to Occupational Exposure Values (ACGIH). TLV-TWAs should be used as a guide in the control of health hazards and not as fine lines between safe and dangerous concentrations. EFFECTS OF A SINGLE (ACUTE) OVEREXPOSURE: INHALATION:
Breathing 80% or more oxygen at atmospheric pressure for more than a few hours maycause nasal stuffiness, cough, sore throat, chest pain and breathing difficulty. Breathingoxygen at higher pressure increases the likelihood of adverse effects within a shorter timeperiod. Breathing pure oxygen under pressure may cause lung damage and also centralnervous system effects resulting in dizziness, poor coordination, tingling sensation, visual andhearing disturbances, muscular twitching, unconsciousness and convulsions. Breathing ofoxygen under pressure may cause prolongation of adaptation to darkness and reducedperipheral vision. SKIN CONTACT: SKIN ABSORPTION:
No evidence of adverse effects from available information. SWALLOWING:
This product is a gas at normal temperature and pressure. EYE CONTACT:
No evidence of adverse effects from available information.
Copyright 2005, Praxair Canada Inc. Page 1 of 8 EFFECTS OF REPEATED (CHRONIC) OVEREXPOSURE:
No evidence of adverse effects from available information. OTHER EFFECTS OF OVEREXPOSURE:
See "Notes to Physician", in the "First Aid" section. MEDICAL CONDITIONS AGGRAVATED BY OVEREXPOSURE:
See "Notes to Physician", in the "First Aid" section. SIGNIFICANT LABORATORY DATA WITH POSSIBLE RELEVANCE TO HUMAN HEALTH HAZARD EVALUATION: CARCINOGENICITY:
Not listed as carcinogen by OSHA, NTP or IARC. 3. Composition and Information on Ingredients COMPONENTS CONCENTRATION 4. First Aid Measures INHALATION:
If inhaled, remove to fresh air. If not breathing, give artificial respiration. Keep patient warm and at rest. Get medicalattention. Advise the physician that the victim has been exposed to high concentration of oxygen. SKIN CONTACT: SWALLOWING:
This product is a gas at normal temperature and pressure. EYE CONTACT: NOTES TO PHYSICIAN: Supportive treatment should include immediate sedation, anti-convulsive therapy if needed, and rest. Animal studiessuggest that the administration of certain drugs, including phenothiazine drugs and chloroquine, increase thesusceptibility to toxicity from oxygen at high concentrations or pressures. Animal studies also indicate that vitamin Edeficiency may increase susceptibility to oxygen toxicity. Airway obstruction during high oxygen tension may causealveolar collapse following absorption of the oxygen. Similarly, occlusion of the eustachian tubes may cause retraction ofthe eardrum and obstruction of the paranasal sinuses may produce “vacuum-type” headache. Newborn prematureinfants exposed to high oxygen concentrations may suffer delayed retinal damage, which can progress, to retinaldetachment and blindness (retrolental fibroplasia). Retinal damage can also occur in adults exposed to 100% oxygenunder greater that atmospheric pressure, particularly in individuals whose retinal circulation has been previouslycompromised.All individuals exposed for only periods to oxygen at high pressure and all that exhibit overt oxygen toxicity should haveophthalmologic examination.5. Fire Fighting Measures FLAMMABLE : IF YES, UNDER WHAT CONDITIONS?
V i g o r o u s l y a c c e l e r a t e scombustion. EXTINGUISHING MEDIA:

Copyright 2005, Praxair Canada Inc. Page 2 of 8 PROTECTION OF FIREFIGHTERS: WARNING! Evacuate all personnel from danger area. Immediately deluge cylinders with water from maximum distance
until cool; then move them away from fire area if without risk. SPECIFIC PHYSICAL AND CHEMICAL HAZARDS:
Oxidizing agent, vigorously accelerates combustion. Contact with flammable materials may cause fire or explosion. Container may rupture due to heat of fire. Vapours are extremely irritating. Contact may cause burns to skin and eyes. No part of a container should be subjected to a temperature higher than 52 C. See incompatibility in Section 10. Mostcontainers are provided with a pressure relief divice designed to vent contents when they are exposed to elevatedtemperature. Smoking, flames and electrric sparks in the presence of enriched oxygen atmospheres are potentialexplosion hazards. SENSITIVITY TO IMPACT: SENSITIVITY TO STATIC DISCHARGE: PROTECTIVE EQUIPMENT AND PRECAUTIONS FOR FIREFIGHTERS:
Firefighters should wear self-contained breathing apparatus and full fire-fighting turnout gear. FLAMMABLE LIMITS IN AIR, % by volume: FLASH POINT: AUTOIGNITION TEMPERATURE: 6. Accidental Release Measures STEPS TO BE TAKEN IF MATERIAL IS RELEASED OR SPILLED: Personal Precautions: WARNING!
Shut off flow if you can do so without risk. Ventilate area or move cylinder to a well-ventilated area. Remove all flammable materials from vicinity. Oxygen must never be permitted to strike an oily surface,greasy clothes, or other combustible material. Environmental Precautions:
Discard any product, residue, disposable container, or liner in an environmentally acceptable manner, in full compliancewith federal, provincial, and local regulations. If necessary call your local supplier. 7. Handling and Storage PRECAUTIONS TO BE TAKEN IN HANDLING:
Use piping and equipment adequately designed to withstand pressures to be encountered. Ground all equipment. Store and use with adequate ventilation at all times. Use only in a closed system constructed of corrosion resistantmaterials. NOTE: Reverse flow into cylinder may cause rupture. Use a check valve or other protective apparatus inany lines or piping from the cylinder to prevent reverse flow. For additional information refer to CGA pamphlet P-1. (Seesection 16 for more details).

supervision of personnel experienced in the use of underwater breathing gas mixtures. Become familiar with theeffects, methods, frequency and duration of use, hazards, side effects and precautions to be taken. PRECAUTIONS TO BE TAKEN IN STORAGE:
Store and use with adequate ventilation. Separate flammable cylinders from oxygen, chlorine, and other oxidizers by atleast 6 m or use a barricade of non-combustible material. This barricade should be at least 1.5 m high and have a fireresistance rating of at least ½ hour. Firmly secure cylinders upright to keep them from falling or being knocked over. Screw valve protection cap firmly in place by hand. Post “No Smoking or Open Flames” signs in storage and use areas. There must be no sources of ignition. All electrical equipment in storage areas must be explosion-proof. Storage areasmust meet national electric codes for Class 1 hazardous areas. Store only where temperature will not exceed 52 C. Store full and empty cylinders separately. Use a first-in, first-out inventory system to prevent storing full cylinders forlong periods. For additional information refer to CGA pamphlet P-2305(for welding and cutting). See section 16. OTHER HAZARDOUS CONDITIONS OF HANDLING, STORAGE, AND USE: High-pressure, oxidizing gas. Use piping and equipment adequately designed to withstand pressures to be encountered. Vigorously accelerates combustion. Keep oil, grease, and combustibles away. Store and use with adequate ventilation at all times. Close valve after each use; keep closed even when empty. Prevent reverse flow. Reverse flow into cylinder may cause rupture. Use a check valve or other protective device in any line or piping from the cylinder. When returning cylinder to supplier, be sure valve is closed, then install valve outlet plug tightly. Never work on a pressurized system. If there is a leak, close the cylinder valve.

At atmospheric concentration and pressure, oxygen poses no toxicity hazards. At high concentrations, newbornpremature infants may suffer delayed retinal damage (retrolental fibroplasia) that can progress to retinal detachment andblindness. Retinal damage may also occur in adults exposed to 100% oxygen for extended periods (24 to 48 hours) or atgreater than atmospheric pressure, particularly in individuals whose retinal circulation has been previously compromised. All individuals exposed for long periods to oxygen at high pressure and all who exhibit overt oxygen toxicity should haveophthalmologic examinations.
At two or more atmospheres, toxicity to the Central Nervous System (CNS) occurs. Symptoms include nausea, vomiting,dizziness or vertigo, muscle twitching, vision changes, and loss of consciousness and generalized seizures. At threeatmospheres, CNS toxicity occurs in less than two hours; at six atmospheres, in only a few minutes.
Patients with chronic obstructive pulmonary disease retain carbon dioxide abnormally. If oxygen is administered, raisingtheir blood oxygen concentration, their breathing becomes depressed and retained carbon dioxide rises to a dangerouslevel.
Animal studies suggest that the administration of certain drugs, including phenothiazine drugs and chloroquine, increasesthe susceptibility to toxicity from oxygen at high concentrations or pressures. Animal studies also indicate that vitamin Edeficiency may increase susceptibility to oxygen toxicity.
Airway obstruction during high oxygen tension may cause alveolar collapse following absorption of the oxygen. Similarly,occlusion of the eustachians tubes may cause retraction of the eardrum and obstruction of the paranasal sinuses mayproduce vacuum-type headache. 12. Ecological Information
