3. HAZARD IDENTIFICATION
EMERGENCY OVERVIEW: Oxygen is a colol1ess, odorless, oxidizing gas, or a colorless, odorless, cryogenic
liquid. The chief heaRh hazard presented by this gas at atmospheric pressures is respiratory system irritation after
overexposure to high oxygen concentrations. Contact with the cryogenic liquid can cause frostbite and burns to
exposed tissue. The main physical hazard associated with releases of this gas is related to its oxidizing power.
This gas is not flammable, but is an oxidizing gas which can accelerate the burning of common combustible
materials.. The cryogenic liquid will rapidly boil to the gas at standard temperatures and pressures. Emergency
responders must practice extreme caution when approaching oxygen releases because of the extreme fire
potential.

SYMPTOMS OF OVEREXPOSURE BY ROUTE OF EXPOSURE: The most significant route of overexposure for
this gas or cryogenic liquid by inhalation. Skin and eye contact is also possible for the cryogenic liquid. The
following paragraphs deSCribe symptoms of exposure by route of exposure.
INHALATION: Nonnally, air contains 21 % oxygen. No health effects have been observed in people exposed to
50% Oxygen at 1 atm. for 24 hours or longer. Exposure to this concentration at 3 atmospheres or more can cause
adverse effects. High concentrations of this gas create an oxygen-riCh environment. Individuals breathing such an
atmosphere containing 51-100% Oxygen may experience nausea, dizziness, coughing, and bronchial irritation.
Exposures to high Oxygen concentrations, especially at elevated pressures, can cause, hypothermia, increased
depth of respiration, bradycardia, pulmonary discomfort, central nervous system effects (e.g., mood changes,
dizziness), peripheral vasoconstriction, amblyopia (loss of vision), seizures, or death. Exposure levels to pure
oxygen which have produced the adverse symptoms described above are summarized below.

NOTE: Pure oxygen at 1/3 atmospheric pressure can be inhaled for weeks without symptoms. Inhalation of pure
oxygen for up to 16 hours per day for many days and 65% oxygen in air for extended periods does not cause
symptoms of oxygen to)(icity.
OTHER POTENTIAL HEALTH EFFECTS: Contact of the skin or eyes with cryogenic liquid or rapidly e)(panding
gases (which are released under high pressure) may cause frostbite. Symptoms of frostbite include change in skin
color to white or grayish-yellow. The pain after contact with liquid can quickly subside. Ingestion and absorption
through the skin are not considered significant routes of entry of oxygen into the body.

3. HAZARD IDENTIFICATION (Continued)
HEALTH EFFECTS OR RISKS FROM EXPOSURE: An Explanation in Lay Terms, Overexposure to Oxygen may
cause the following health ellects:
ACUTE: The most significant hazard associated with this gas is inhalation of oxygen-rich atmospheres, Symptoms
of overexposure to Oxygen-rich atmospheres include nausea, dizziness, respiratory problems, lowering of body
temperature, loss of viSion, seizures, or death, Contact with cryogenic liquid or rapidly expanding gases (which are
released under high pressure) may cause frostbite,
CHRONIC: Long-term exposure to high atmospheric concentrations of oxygen at normal pressure or elevated
pressure may produce severe thickening and scarring of lung tissues, Blood hemoglobin concentration decreases
(thus reducing oxygen-carrying capacity) with prolonged exposure to high concentrations, See Section 11

What should I do if a hazardous situation occurs?
4. FIRST-AID MEASURES
RESCUERS SHOULD NOT ATTEMPT TO RETRtEVE VICTIMS OF OVER-EXPOSURE WITHOUT ADEQUATE
PERSONAL PROTECTIVE EQUIPMENT. At a minimum, Self,Contained Breathing Apparatus Personal
Protective equipment (and fire retardant clothing, if appropriate) should be worn to protect against high
oxygen content or super-heated gases in the event of fire.
Victim(s) must be taken for medical attention, 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 care providers should refer
to Section 11 of this MSDS for additional information,
Remove victim(s) to fresh air, as quickly as possible, Trained personnel should administer supplemental oxygen
and/or cardio·pulmonary resuscitation, if necessary, Supplemental oxygen is not normally appropriate, Victims tend
to recover rapidly, when removed from the hypoxic exposure,
In case of frostbite, place the frostbitten part in warm water. DO NOT USE HOT WATER. If warm water is not
available, or is impractical to use, wrap the allected parts gently in blankets, Altematively, if the fingers or hands are
frostbitten, place the affected area in the armpit, Encourage victim to gently exercise the affected part while being
warmed, Seek immediate medical attention,
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: Pre-existing respiratory conditions may be aggravated
by overexposure to Oxygen,
RECOMMENDATIONS TO PHYSICIANS: Treat symptoms and reduce overexposure. Symptoms of overexposure
usually are relieved quickly. Immediate sedation and anticonvulsive therapy should be provided, as needed,

5. FIRE-FIGHTING MEASURES (Continued)
RESPONSE TO FIRE INVOLVING CRYOGEN: Cryogenic oxygen may contribute to the ignition of any
combustible material, including asphalt and wood. Extreme caution must be used when cryogenic oxygen
storage vessels are involved in a fire. Cryogenic liquids can be particularly dangerous during fires because of
their potential to rapidly freeze water. Careless use of water may cause heavy icing. Furthermore, relatively warm
water greatly increases the evaporation rate of Oxygen. If large concentrations of Oxygen gas are present, the water
vapor in the surrounding air will condense, creating a dense fog that may make it difficult to find fire exits or
equipment. Liquid Oxygen, when exposed to the atmosphere, will produce a cloud of ice/fog in the air upon its
release.
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. Do not enter areas which have more than 23.5% oxygen in the atmosphere, since a
serious fire and explosion hazard exists. Remove all flammable and combustible materials from vicinity of a release,
if it can be done without risk to firefighters. Direct water onto vessels to keep the vessels cool. Shut-off the flow of
oxygen or move vessels from fire area if it can be done safely. Withdraw from the area in case of rising sounds from
venting safety devices or any discoloration of vessels due to fire.
6. ACCIDENTAL RELEASE MEASURES
SPILL AND LEAK RESPONSE: Uncontrolled releases should be responded to by trained personnel using
pre-planned procedures. Proper protective equipment should be used. In case of a release, clear the affected area
and protect people. Minimum Personal Protective Equipment should be Level B: fire protective clothing,
mechanically-resistant, fire protective gloves and Self·Contained Breathing Apparatus. In general, DO NOT
ENTER AN AREA IF THE OXYGEN CONTENT EXCEEDS 23.5%. USE VENTILATION TO REDUCE THE
OXYGEN LEVELS. Locate and seal the source of the leaking gas. Protect personnel attempting the shut-off with
water-spray. Allow the gas to dissipate. Monitor the surrounding area for oxygen levels. The atmosphere must
have at least 19.5 percent and less than 23.5% oxygen before personnel can be allowed in the area without SelfContained Breathing Apparatus. Attempt to close the main source valve prior to entering the area. If this does not
stop the release (or if it is not possible to reach the valve), allow the gas to release in-place or remove it to a safe
area and allow the gas to be released there.
RESPONSE TO CRYOGENIC RELEASE: Clear the affected area and allow the liquid to evaporate and the gas to
dissipate. After the gas is formed, follow the instructions provided in the previous paragraph. If the area must be
entered by emergency personnel, SCBA, Kevlar gloves, and appropriate foot and leg protection and fire protective
clothing must be worn.
PART III
How can I prevent hazardous situations from occurring?
7. HANDLING and STORAGE
WORK PRACTICES AND HYGIENE PRACTICES: Do not eat or drink while handling chemicals. Be aware of any
signs of overexposure to this gas (see Section 3, Hazard Information).
STORAGE AND HANDLING PRACTICES: Cylinders should be stored in dry, well-ventilated areas away from
sources of heat. Compressed gases can present significant safety hazards. Store containers away from heavily
trafficked areas and emergency exits. Post "No Smoking or Open Flames" signs in storage or use areas.
SPECIAL PRECAUTIONS FOR HANDLING GAS CYLINDERS: Protect cylinders against physical damage. Store
in cool, dry, well-ventilated, fireproof area, away from flammable materials and corrosive atmospheres. Store away
from heat and ignition sources and out of direct sunlight. Do not store near elevators, corridors or loading docks. Do
not allow area where cylinders are stored to exceed 52°C (125°F). Use only storage containers and equipment
(pipes, valves, fittings to relieve pressure, etc.) designed for the storage of Oxygen. Do not store containers where
they can come into contact with moisture.
Cylinders should be stored upright and be firmly secured to prevent falling or being knocked over. Cylinders can be
stored in the open, but in such cases, should be protected against extremes of weather and from the dampness of
the ground to prevent rusting.
Keep Dewar flasks of liquid oxygen covered with loose fitting cap. This prevents air or moisture from entering the
container, yet allows pressure to escape. Use only the stopper or plug supplied with the container. Ensure that ice
does not form in the neck of flasks. If the neck of Dewar flask is blocked by ice or "frozen" air, follow owner's
instruction for removing it. A plugged Dewar or storage flask may develop sufficient pressure to cause catastrophic
failure. Ice can also cause pressure release valves to fail. Never tamper with pressure relief devices in valves and
cylinders. The temperature of Liquid Oxygen is sufficiently cold to condense and freeze most gases. Consequently,
there is a danger of pipes or vents becoming plugged. Liquid Oxygen should therefore be stored and handled under
positive pressure or in a closed system to prevent the infiltration and solidification of air or other gases.

7. HANDLING and STORAGE (Continued)
SPECIAL PRECAUTIONS FOR HANDLING GAS CYLINDERS (continued): The following rules are applicable to
situations in which cylinders are being used:
Before Use: Move cylinders with a suitable hand-truck, Do not drag, slide or roll cylinders, Do not drop cylinders or
permit them to strike each other. Secure cylinders firmly, Leave the valve protection cap, if provided, in-place until
cylinder is ready for use,
During Use: Use designated CGA fittings and other support equipment. Do not use adapters, Do not heat cylinder
by any means to increase the discharge rate of the product from the cylinder, Use check valve or trap in discharge
line to prevent hazardous backflow into the cylinder, Do not use oils or grease on gas-handling fittings or equipment.
After Use: Close main cylinder valve, Replace valve protection cap, if provided. MarK empty cylinders "EMPTY".
NOTE: Use only DOT or ASME code containers. Cylinders must not be recharged except by or with the consent of
owner. For additional information refer to the Compressed Gas Association Pamphlet P-1. Safe Handling of
Compressed Gases in Containers. For cryogenic liquids, refer to CGA P-12, Safe Handling of Cryogenic Liquids,
AddITionally, refer to CGA Bulletins G4.3, "Commodity Specification for Oxygen", and G4.1 'Cleaning Equipment
for Oxygen Service',
PROTECTIVE PRACTICES DURING MAINTENANCE OF CONTAMINATED EQUIPMENT: Follow practices
indicated in Section 6 (Accidental Release Measures). Make certain applicallon eqUipment is locked and tagged-out
safely. Purge gas handling equipment with inert gas (e.g., Nitrogen) before attempting repairs,
TANK CAR SHIPMENTS: Tank cars carrying Oxygen should be loaded and unloaded in strict accordance with tankcar owner's recommendations and all established on-sile safety procedures. Appropriate personal protective
equipment must be used during tank car operations (see Section 8). All loading and unloading equipment must be
inspected, prior to each use, Loading and unloading operations must be attended, at all times, Tank cars must be
level and wheels must be locked or blocked prior to loading or unloading. Tank car (for loading) or storage tank (for
unloading) must be verified to be correct for receiving this product and be properly prepared, prior to starting the
transfer operations, Hoses must be verified to be clean and free of incompatible chemicals, prior to connection to the
tank car or vessel. Valves and hoses must be verified to be in the correct positions, before starting transfer operations,
A sample (if required) must be taken and verified (if required) prior to starting transfer operations, All lines must be
blown-down and purged before disconnecting them from the tank car or vessel. Refrigerated Liquid Oxygen is
capable of causing the ignition of asphalt. Transfers should be performed on concrete surfaces,
8. EXPOSURE CONTROLS· PERSONAL PROTECTION
VENTILATION AND ENGINEERING CONTROLS: Use with adequate ventilation to maintain Oxygen levels
between 19,5% and 23,5% in the work area. Local exhaust ventilation is preferred, because it prevents Oxygen
dispersion into the worK place by eliminating it at its source. If appropriate, install automatic monitoring equipment to
detect the level of Oxygen,
RESPIRATORY PROTECTION: Maintain oxygen levels above 19,5% and below 23,5% in the worKplace. Use
supplied air respiratory protection during emergency response to a release of Oxygen, 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,
Oxygen levels below 19,5% are considered IDLH by OSHA. In such atmospheres, use of a full-facepiece
pressure/demand SCBA or a full facepiece, supplied air respirator with auxiliary self-contained air supply is required
under OSHA's Respiratory Protection Standard (1910.134-1998). DO NOT ENTER AN AREA IF THE OXYGEN
CONTENT EXCEEDS 23.5%.
EYE PROTECTION: Safety glasses. Face-shields must be wom when using cryogenic Oxygen. If necessary, refer
to U.S, OSHA 29 CFR 1910.133, or Canadian Standards,
HAND PROTECTION: Wear mechanically-resistant gloves when handling cylinders of Oxygen. Use Iowtemperature protective gloves (e.g., Kevlar) when worKing with containers of Liquid Oxygen. If necessary, refer to
U.S, OSHA 29 CFR 1910.138 or appropriate Standards of Canada.
BODY PROTECTION: Use body protection appropriate for task, Transfer of large quantities under pressure may
require protective equipment appropriate to protect employees from splashes of liquefied product, as well provide
sufficient insulation from extreme cold. 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.
