EMERGENCY OVERVIEW
Odorless, colorless, non-flammable gas. Oxidizer. Will accelerate combustion and increase the risk of
fire and explosion in combustible or flammable materials. Non-toxic. Prolonged inhalation of high
concentrations may cause coughing and lung effects. Contents under pressure. Use and store below
125 掳F.

Carcinogenicity: -- NTP: No IARC: No OSHA: No
EYE EFFECTS: Harmful effects are not expected.
SKIN EFFECTS: Harmful effects are not expected.
INGESTION EFFECTS: Not applicable. Product is a gas.
INHALATION EFFECTS: Oxygen is not acutely toxic under normal pressure. Prolonged inhalation of high
oxygen concentrations (> 75%) may affect coordination, attention, and cause tiredness or respiratory irritation.
Inhalation for several hours may cause cough, sore throat, chest pain and difficulty breathing.
Oxygen is more toxic when inhaled at elevated pressures. Depending upon pressure and duration of exposure,
pure oxygen at elevated pressures (i.e.: divers) may cause cramps, dizziness, difficulty breathing, convulsions,
edema, and death.
Elevated oxygen concentrations in incubators has caused visual impairment and blindness in premature infants.
High oxygen concentrations primarily affect eyes which are not fully developed (see Section 11).
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: May aggravate chronic obstructive
pulmonary (lung) disease.
POTENTIAL ENVIRONMENTAL EFFECTS: Not expected to be toxic to fish and wildlife.
4. First Aid Measures
EYES: None required.
SKIN: None required.
INGESTION: None required.
INHALATION: Overexposure to oxygen is not anticipated under normal working conditions. High oxygen
concentrations in the air may present a fire and explosion hazard. PROMPT MEDICAL ATTENTION IS
MANDATORY IN ALL CASES WHEN OXYGEN IS INHALED UNDER PRESSURE (i.e.: as in scuba
diving). Conscious persons should be assisted to an uncontaminated area and inhale fresh air. Quick removal
from the contaminated area is most important. Further treatment should be symptomatic and supportive. Inform
the treating physician that the patient could be experiencing hyperoxia.

5. Fire Fighting Measures
Conditions of Flammability: Not flammable, Oxidizer
Flash point: Method: Autoignition
None Not Applicable Temperature: None
LEL(%): None UEL(%): None
Hazardous combustion products: None
Sensitivity to mechanical shock: None
Sensitivity to static discharge: None
FIRE AND EXPLOSION HAZARDS: High oxygen concentrations vigorously accelerate combustion. Will
support or initiate combustion/ explosion of organic matter and other oxidizable material. Cylinder may vent
rapidly or rupture violently from pressure when involved in a fire situation.
EXTINGUISHING MEDIA: Water spray to keep cylinders cool. Extinguishing agent appropriate for the
combustible material.
FIRE FIGHTING INSTRUCTIONS: If possible, stop the flow of oxygen which is supporting the fire.
Firefighters should wear respiratory protection (SCBA) and full turnout or Bunker gear. Continue to cool fire-
exposed containers until well after flames are extinguished.
6. Accidental Release Measures
Evacuate all personnel from affected area. A leak near combustible or flammable materials may represent a
severe fire or explosion hazard. Eliminate all ignition sources. Ventilate enclosed areas. If it can be done
without risk, stop the flow of gas or remove cylinder to outside. Use appropriate protective equipment (See
Section 8). If leak is in user's equipment, be certain to purge piping with inert gas prior to attempting repairs. If
leak is in container or container valve, contact the appropriate emergency telephone number listed in Section 1
or call your closest BOC location.
7. Handling and Storage
Electrical classification: Nonhazardous
Dry product is noncorrosive and may be used with all materials of construction. Moisture causes metal oxides
which are formed with air to be hydrated so that they include volume and lose their protective role (rust
formation). Concentrations of SO2, C12, salt, etc. in the moisture enhances the rusting of metals in air. Carbon
steels and low alloy steels are acceptable for use at lower pressures.
For high pressure applications stainless steels are acceptable as are copper and its alloys, nickel and its alloys,
brass bronze, silicon alloys, Monel 庐, Inconel 庐 and beryllium. Lead and silver or lead tin alloys are good
gasket materials. Teflon 庐, Teflon 庐 composites, or Kel-F 庐 are preferred non-metallic gasket materials.
Oxygen should not be used as a substitute for compressed air in pneumatic equipment since this type generally
contains flammable lubricants. Equipment to contain oxygen must be 鈥渃leaned for oxygen service鈥?. Check with
the supplier to verify oxygen compatibility for the service conditions.

PRODUCT NAME: OXYGEN
Stationary customer site vessels should operate in accordance with the manufacturer's and BOC鈥檚 instruction.
Do not attempt to repair, adjust or in any other way modify the operation of these vessels. If there is a
malfunction or other type of operations problem with the vessel, contact the closest BOC location immediately.
Valve protection caps must remain in place unless container is secured with valve outlet piped to use point. Do
not drag, slide or roll cylinders. Use a suitable hand truck for cylinder movement. Use a pressure reducing
regulator when connecting cylinder to lower pressure piping or systems. Do not heat cylinder by any means to
increase the discharge rate of product from the cylinder. Use a check valve or trap in the discharge line to
prevent hazardous back flow into the system. Do not insert any object (i.e.: screwdriver) into valve cap
openings as this can damage the valve causing leakage.
Protect cylinders from physical damage. Store in cool, dry, well-ventilated area away from heavily trafficked
areas, emergency exits, flammables and combustibles. Do not allow the temperature where cylinders are stored
to exceed 125oF (52oC). Cylinders should be stored upright and firmly secured to prevent falling or being
knocked over. Full and empty cylinders should be segregated. Use a "first in-first out" inventory system to
prevent full cylinders being stored for excessive periods of time. Post "NO SMOKING OR OPEN FLAMES"
signs in the storage area or use area. There should be no sources of ignition in the storage or use area.
For additional storage recommendations, consult Compressed Gas Association's Pamphlets SB-7, G 4.3, G4.1,
G-4.4, P-2.5, P-2.6, G-4.9, P-14, P-1, SB-2.
Do not release in a confined area. Never carry a compressed gas cylinder or a container of a gas in cryogenic
liquid form in an enclosed space such as a car trunk, van or station wagon. A leak can result in a fire, explosion,
or a toxic exposure.
8. Exposure Controls, Personal Protection
ENGINEERING CONTROLS: Use general ventilation and/or local exhaust as necessary to keep oxygen
concentrations below 23.5%.
EYE/FACE PROTECTION: Safety goggles or glasses as appropriate for the job.
SKIN PROTECTION: Protective gloves made of any suitable material appropriate for the job. Gloves must
be clean and free from oil and grease.
OTHER/GENERAL PROTECTION: Safety shoes.

11. Toxicological Information
SKIN AND EYE:
The incompletely developed retinal circulation is more susceptible to toxic levels of oxygen. In premature
infants, arterial oxygen tension above 150 mm Hg may cause retrolental fibroplasia. Permanent blindness may
occur several months later. One case of severe retinal damage in an adult was reported. An individual suffering
from myasthenia gravis developed irreversible retinal atrophy after breathing 80% oxygen for 150 days.
INHALATION:
Human volunteers which inhaled 90-95% oxygen through a face mask for 6 hours showed signs of tracheal
irritation and fatigue. Other symptoms (which might have been caused by placing a tube into the trachea during
the experiment) included: sinusitis, conjunctivitis, fever, and symptoms of acute bronchitis.
Poisoning began in dogs 36 hours after inhalation of pure oxygen at atmospheric pressure. Distress was seen
within 48 hours and death within 60 hours.
