3. HAZARD IDENTIFICATION
EMERGENCY OVERVIEW: Oxygen is a colorless, odorless gas. There are no significant health hazards related to overexposure to Oxygen, except in a hyperbaric
environment, which is unlikely in an industrial setting. The main hazard associated with releases of this gas is it’s powerful oxidizing power. In high oxygen content
atmospheres, common combustible materials can become highly flammable. Emergency responders must practice extreme caution when approaching oxygen
releases because of the extreme fire potential.
SYMPTOMS OF OVER-EXPOSURE BY ROUTE OF EXPOSURE: The most significant route
of over-exposure for this product is by inhalation.
INHALATION: Due to the small size of an individual cylinder of this product, no unusual health
effects from exposure to the product are anticipated under routine circumstances of use. If this
product is released in a small, poorly ventilated area (i.e. an enclosed or confined space), high
concentrations of this gas can cause an oxygen-rich environment. Exposure to an oxygen-rich
environment is only known to cause adverse health effects when the duration of exposure is in
excess of 17 hours. An exposure of this duration is extremely unlikely from use of this product
due to the small overall cylinder size and content.
HEALTH EFFECTS OR RISKS FROM EXPOSURE: An Explanation in Lay Terms. Overexposure to Oxygen may cause the following health effects:
ACUTE: Due to the small size of the individual cylinder of this product, no unusual health
effects from exposure to the product are anticipated under routine circumstances of use. The
most significant hazard associated with this gas is inhalation of oxygen-rich atmospheres.
CHRONIC: There are currently no known adverse health effects associated with chronic
exposure to this gas.
TARGET ORGANS: ACUTE: Respiratory system. CHRONIC: None known.

4. FIRST-AID MEASURES
No unusual health effects are anticipated after exposure to this product, due to the small cylinder size. Supplemental oxygen is not normally
appropriate. Victims tend to recover rapidly, when removed from the hypoxic exposure. Victim(s) who experience any adverse effect after overexposure to this product must be taken for medical attention. Physicians should be advised of the victim’s exposure to an oxygen-rich environment.
Rescuers should be taken for medical attention, if necessary. Take copy of label and MSDS to physician or other health professional with victim(s).
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: None known.
RECOMMENDATIONS TO PHYSICIANS: Treat symptoms and reduce over-exposure.
ADDITIONAL NOTES TO PHYSICIANS: Animal studies suggest that the administration of certain drugs, including phenothiazine drugs and
chloroquine, increase the susceptibility to toxicity from oxygen at high pressures. Animal studies also indicate that vitamin “E” deficiency 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
Eustachian tubes may cause retraction of the eardrum and obstruction of the paranasal sinuses may produce “vacuum-type” headache. All
individuals exposed for long periods to oxygen at high pressure and who exhibit overt oxygen toxicity should have ophthalmologic examinations.

when involved in fire, may rupture or burst in the heat of the fire. Oxygen will support and
accelerate combustion. Common combustible materials will burn more readily in elevated
OX
oxygen environments, and some materials which are non-combustible in air will burn in an
oxygen-enriched atmosphere. Direct water onto cylinders to keep cool. Shut-off the flow of
OTHER
oxygen or move cylinders from fire area if it can be done safely. Rescue personnel should be
aware of the extreme fire hazards associated with oxygen-enriched atmospheres.
FIRE EXTINGUISHING MATERIALS: Non-flammable gas. Use extinguishing media appropriate for surrounding fire.
Explosion Sensitivity to Mechanical Impact: Not Sensitive.
Explosion Sensitivity to Static Discharge: Not Sensitive.
SPECIAL FIRE-FIGHTING PROCEDURES: Structural fire-fighters must wear Self-Contained Breathing Apparatus and full protective equipment.
Other information for pre-planning can be found in the North American Emergency Response Guidebook.
6. ACCIDENTAL RELEASE MEASURES
LEAK RESPONSE: Due to the small size and content of the cylinder, an accidental release of this product presents significantly less risk and other
safety hazards than a similar release from a larger cylinder. However, as with any chemical release, extreme caution must be used during
emergency response procedures. In the event of a release in which the atmosphere is unknown, and in which other chemicals are potentially
involved, evacuate immediate area. Uncontrolled releases should be responded to by trained personnel using pre-planned procedures. Proper
protective equipment should be used. In case of a leak, clear the affected area, protect people, and respond with trained personnel. Clear area of
release of combustible materials until gas has dissipated. Adequate fire protection must be provided.
In general, DO NOT ENTER AN AREA IF THE OXYGEN CONTENT EXCEEDS 23.5%. USE VENTILATION TO REDUCE THE OXYGEN
LEVELS. For emergency disposal, secure the cylinder and slowly discharge the gas to the atmosphere in a well-ventilated area or outdoors. Allow
the gas, which is lighter than air to dissipate. If necessary, monitor the surrounding area (and the original area of the release) for oxygen.
If leaking incidentally from the cylinder contact your supplier.
7. HANDLING and USE
STORAGE AND HANDLING PRACTICES: Cylinders should be firmly secured to prevent falling or being knocked-over. Cylinders must be
protected from the environment, and preferably kept at room temperature approximately 21°C, (70°F). Cylinders should be stored in dry, wellventilated areas away from sources of heat, ignition and direct sunlight. Protect cylinders against physical damage. Store containers away from
heavily trafficked areas and emergency exits. Store away from process and production areas, away from elevators, building and room exits or main
aisles leading to exits. Consider installation of leak detection and alarm for storage and use areas. Have appropriate extinguishing equipment in
the storage area ( i.e. sprinkler system, portable fire extinguishers).
Full and empty cylinders should be segregated. Use a first-in, first-out inventory system to prevent full containers from being stored for long periods
of time. These cylinders are not refillable. WARNING! Do not refill DOT 39 cylinders. To do so may cause personal injury or property
damage.
SPECIAL PRECAUTIONS FOR HANDLING GAS CYLINDERS: WARNING! Compressed gases can present significantly safety hazards. During
cylinder use, use equipment designed for these specific cylinders. Ensure all lines and equipment are rated for proper service pressure.
PROTECTIVE PRACTICES DURING MAINTENANCE OF CONTAMINATED EQUIPMENT: Follow practices indicated in Section 6 (Accidental
Release Measures). Make certain application equipment is locked and tagged-out safely. Purge gas handling equipment with inert gas (i.e.
nitrogen) before attempting repairs. Always use product in areas where adequate ventilation is provided.
8. EXPOSURE CONTROLS - PERSONAL PROTECTION
VENTILATION AND ENGINEERING CONTROLS: No special ventilation systems or engineering controls are needed under normal
circumstances of use. As with all chemicals, use this product in well-ventilated areas.
RESPIRATORY PROTECTION: No special respiratory protection is required under normal circumstances of use. DO NOT ENTER AN AREA IF
THE OXYGEN CONTENT EXCEEDS 23.5%. If respiratory protection is needed, use only protection authorized in the U.S. Federal OSHA
Standard (29 CFR 1910.134), applicable U.S. State regulations, or the Canadian CSA Standard Z94.4-93 and applicable standards of Canadian
Provinces.
EYE PROTECTION: Safety glasses. If necessary, refer to U.S. OSHA 29 CFR 1910.133 or appropriate Canadian Standards.
HAND PROTECTION: No special protection is needed under normal circumstances of use. If necessary, refer to U.S. OSHA 29 CFR 1910.138
or appropriate Standards of Canada.
BODY PROTECTION: No special protection is needed under normal circumstances of use. If a hazard of injury to the feet exists due to falling
objects, rolling objects, where objects may pierce the soles of the feet or where employee’s feet may be exposed to electrical hazards, use foot
protection, as described in U.S. OSHA 29 CFR 1910.136.

11. TOXICOLOGICAL INFORMATION
TOXICITY DATA: Oxygen is the vital element in the atmosphere in which we live and breathe. The atmosphere contains approximately 21%
oxygen. Breathing higher concentrations could lead to oxygen toxicity and pneumonia. Breathing lower oxygen concentrations could lead to
hypoxia. There are toxicity data for Oxygen, but are from studies in a hyperbaric environment and so are not pertinent to exposure in an industrial
setting.
SUSPECTED CANCER AGENT: Oxygen is not found on the following lists: FEDERAL OSHA Z LIST, NTP, CAL/OSHA, IARC; therefore it is not
considered to be, nor suspected to be a cancer-causing agent by these agencies.
IRRITANCY OF PRODUCT: None.
SENSITIZATION OF PRODUCT: Oxygen is not a sensitizer.
REPRODUCTIVE TOXICITY INFORMATION: Listed below is information concerning the effects of Oxygen on the human reproductive system.
Mutagenicity: Mutation data have been reported for Oxygen, but are from studies in a hyperbaric environment.
Embryotoxicity: Oxygen has not been reported to cause embryotoxic effects in humans.
Teratogenicity: Human teratogenic effects by inhalation have been reported, with developmental abnormalities of the fetal cardiovascular
system; however, these data are from studies or incidences in a hyperbaric environment and are not related to casual or industrial exposure.
Reproductive Toxicity: Oxygen has not been reported to cause adverse reproductive effects in humans.
A mutagen is a chemical which causes permanent changes to genetic material (DNA) such that the changes will propagate through generation
lines. An embryotoxin is a chemical which causes damage to a developing embryo (i.e. within the first eight weeks of pregnancy in humans), but
the damage does not propagate across generational lines. A teratogen is a chemical which causes damage to a developing fetus, but the damage
does not propagate across generational lines. A reproductive toxin is any substance which interferes in any way with the reproductive process.
BIOLOGICAL EXPOSURE INDICES (BEIs): Currently, Biological Exposure Indices (BEIs) have not been determined for Oxygen.
12. ECOLOGICAL INFORMATION
ENVIRONMENTAL STABILITY: Oxygen occurs naturally in the atmosphere. The gas will be dissipated rapidly in well-ventilated areas.
EFFECT OF MATERIAL ON PLANTS or ANIMALS: Due to the small cylinder size, no adverse effect on animals or plants is anticipated if one
cylinder of this product is released.
EFFECT OF CHEMICAL ON AQUATIC LIFE: No evidence is currently available on this product’s effects on aquatic life.
13. DISPOSAL CONSIDERATIONS
PREPARING WASTES FOR DISPOSAL: Waste disposal must be in accordance with appropriate U.S. Federal, State, and local regulations and

16. OTHER INFORMATION
MIXTURES: When two or more gases or liquefied gases are mixed, their hazardous properties may combine to create additional, unexpected
hazards. Obtain and evaluate the safety information for each component before you produce the mixture. Consult an Industrial Hygienist or
other trained person when you make your safety evaluation of the end product. Remember, gases and liquids have properties which can
cause serious injury or death.
INFORMATION ABOUT DOT-39 NRC (Non-Refillable Cylinder) PRODUCTS
DOT 39 cylinders ship as hazardous materials when full. Once the cylinders are relieved of pressure (empty) they are not considered
hazardous material or waste. Residual gas in this type of cylinder is not an issue because toxic gas mixtures are prohibited. Calibration gas
mixtures typically packaged in these cylinders are Nonflammable n.o.s., UN 1956. A small percentage of calibration gases packaged in DOT
39 cylinders are flammable gas mixtures.
For disposal of used DOT-39 cylinders, it is acceptable to place them in a landfill if local laws permit. Their disposal is no different than that
employed with other DOT containers such as spray paint cans, household aerosols, or disposable cylinders of propane (for camping, torch
etc.). When feasible, we recommended recycling for scrap metal content. CALGAZ will do this for any customer that wishes to return
cylinders to us prepaid. All that is required is a phone call to make arrangements so we may anticipate arrival. Scrapping cylinders involves
some preparation before the metal dealer may accept them. We perform this operation as a service to valued customers who want to
participate.
