Product Name: Oxygen
. CAS: 7782-44-7
Oxygen; Oxygen, compressed (D.O.T.)
DOT I.D No.: UN 1072
Chemical Name and Synonyms:
Oxygen
DOT Hazard Class: Division 2.2
Formula: 02
Chemical Family: Oxidizer
HEALTH HAZARD DATA
Time Weighted Average Exposure Limit: '
None established (ACGIH 1994-1995). Oxygen is the "vital element" in the atmosphere in
which we live and breathe.
Symptoms of Exposure:
Breathing high concentrations (greater than 75 molar percent) causes symptoms of
hyperoxia which includes cramps, nausea, dizziness, hypothermia, amblyopia, respiratory
difficulties, bradycardia, fainting spells, and convulsions capable of leading to death. For
additional information on hyperoxia, see Compressed Gas Association's Pamphlet P-14.
Toxicological Properties:
• The property is that hyperoxia which leads to pneumonia. Concentrations
between 25 and 75 molar percent present a risk of inflammation of organic matte
in the body.
• Oxygen is not listed in the LARC, NTP or by OSHA as a carcinogen or potential
carcinogen.
Persons in ill health where such illness would be aggravated by exposure to
oxygen should not be allowed to work with or handle this product.
•
Recommended First Aid Treatment:
Prompt medical attention is mandatory in all cases of overexposure to oxygen. Rescue
personnel should be cognizant of extreme fire hazard associated with oxygen -rich
atmosphere.
Conscious persons should be assisted to an uncontaminated area and breathe fresh air.
They should be kept warm and quiet. The physician should be informed that the victim is
experiencing hyperoxia.
Unconscious persons should be moved to an uncontaminated area and given assisted
respiration. When breathing has been restored, treatment should be as above. Continues
treatment should be symptomatic and supportive.
Hazardous Mixtures of other Liquids, Solids or Gases:
Oxygen vigorously accelerates combustion. Contact with all flammable materials should be
avoided. Some materials that are not flammable in air will burn in pure oxygen or oxygen -
enriched atmospheres.

SPILL OR LEAK PROCEDURES
Steps to be taken in case material is released or spilled:
Evacuate all personnel from affected area. Use appropriate protective equipment. If leak
is in user's equipment, be certain to purge piping with an inert gas to attempting repairs. If
leak is in container or container valve, contact your closest supplier location or call the
emergency telephone number listed herein.
Waste disposal methods:
Do not attempt to dispose of waste or unused quantities. Return in the shipping container
properly labeled, with any valve outlet plugs or caps secured and valve protection cap in
place to your supplier. For emergency disposal assistance, contact your closest supplier
location or call the emergency telephone number listed herein.
SPECIAL PROTECTION INFORMATION
Respiratory Protection (Specify type): Positive pressure air line with mask or self-
contained breathing apparatus should be available for emergency use.
Ventilation: See Local Exhaust
Local Exhaust: To prevent accumulation above 25 molar percent.
Protective Gloves: As required; any material
Eye Protection: Safety goggles or glasses
Other Protective Equipment: Safety shoes, safety shower
SPECIAL PRECAUTIONS
Special Labeling Information:
DOT Shipping Name: Oxygen, Compressed
DOT Hazard Class: Division 2.2
DOT Shipping Label: Nonflammable Gas
I.D. No.: UN 1072
Special Handling Recommendation:
Use only in well -ventilated areas. Valve protection caps and valve outlet threaded plugs
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 (<3,000 psig)
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 cylinder. For additional handling recommendations, consult
Compressed Gas Association's Pamphlets P-1, P-14, and G-4.
Special Storage Recommendations:
Protect cylinders from physical damage. Store in cool, dry, well -ventilated area away from
heavily trafficked areas and emergency exits and away from full or empty stored cylinders
which contain flammable products. Do not allow the temperature where cylinders are
stored to exceed 125F (52C). 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. For additional storage recommendations, consult Compressed
Gas Association's Pamphlets P-1, P-14, and G-4.
Other Recommendations or Precautions:
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 "cleaned for oxygen service " See Compressed Gas Association Pamphlet G-
4.1. Compressed gas cylinders should not be refilled except by qualified producers of
compressed gases.
Special Packaging Recommendations:
Carbon steels and low alloy steels are acceptable for use at lower pressures. For high
pressure applications use stainless steels, copper and its alloys, nickel and its alloys,
brass, bronze, silicon alloys, Monel®, Inconel®, or beryllium. Lead and silver or lead and
tin alloys are good gasketing materials. Teflon® and Kel-F® are the preferred nonmetal
gaskets. Special Note: It should be recognized that the ignition temperature of metals and
nonmetals in pure oxygen service decreases with increasing oxygen pressure.
