3. HAZARDS IDENTIFICATION / EMERGENCY OVERVIEW:
Krypton and xenon are noncorrosive, nontoxic, and largely inert. They can act as simple
asphyxiants by displacing air, thereby diluting the concentration of oxygen below levels necessary
to support life. Inhalation in excessive concentrations can result in dizziness, nausea, vomiting,
loss of consciousness, and death. Death may result from errors in judgment, confusion, or loss of
consciousness which prevents self-rescue. At low oxygen concentrations, unconsciousness and
death may occur in seconds without warning.
POTENTIAL HEALTH EFFECTS:
EYE CONTACT: Rare gases are inert and should not cause any eye effects.
SKIN CONTACT: Rare gases are inert and should not cause any skin effects.

INHALATION: These gases are inert and are classified as simple asphyxiants. Inhalation
in excessive concentrations can result in dizziness, nausea, vomiting, loss
of consciousness, and death. Death may result from errors in judgment,
confusion, or loss of consciousness which prevent self-rescue. At low
oxygen concentrations, unconsciousness and death may occur in seconds
without warning.
4. FIRST AID MEASURES
INHALATION: Remove the victim from the contaminated area while protecting yourself from
exposure by wearing a supplied air type respirator. Put a similar respirator on the
victim. Have someone contact medical assistance immediately. If the victim
has stopped breathing: Open the victims airway, loosen the collar and belt, and
administer artificial respiration. Administer oxygen through a bag-valve mask.
Check the pulse. If the heart stops, administer CPR. If the heart beat is very
slow, irregular or weak, be prepared to administer CPR. Continue your efforts
until help arrives or the victim starts to breathe on his own. Do not leave the
victim alone. Keep the victim warm and quiet. If the victim is unconscious but
breathing: Lay him on his back. If he is vomiting, turn his head to the side.
Clear and open his airway and loosen tight clothing. If available, give him oxygen
to breathe. Keep him warm and quiet. Check his pulse periodically and be ready
to administer CPR. Do not give an unconscious person anything to drink. If the
victim is conscious but coughing or short of breath: Lay him down, cover
him with a blanket and keep him quiet. Loosen tight clothing. Give him oxygen
to breathe until help arrives. Check his pulse periodically. Do not leave him
unattended. If the victim is conscious and not coughing or short of breath:
Lay him down, cover him with a blanket and keep him quiet. Loosen tight
clothing. Check his pulse periodically. Do not leave him unattended.
5. FIRE FIGHTING MEASURES
FLASH POINT: Nonflammable.
AUTO-IGNITION TEMPERATURE: Does not apply.
FIRE AND EXPLOSION HAZARDS: Inert gases are noncombustible. However, if
system should rupture due to a fire, these gases
may displace air to the point where there is not
enough oxygen to support life.
UPPER EXPLOSIVE / FIRE LIMITS: Nonflammable gas. Not applicable.
LOWER EXPLOSIVE / FIRE LIMITS: Nonflammable gas. Not applicable.
EXTINGUISHING MEDIA: Krypton/Xenon cannot catch fire. Use media
appropriate for surrounding fire.
SPECIAL FIRE FIGHTING PROCEDURES: Krypton/Xenon are inert gases, and do not
represent any fire hazard.
6. ACCIDENTAL RELEASE MEASURES
SPILL OR LEAK Evacuate spill or leak area, allow concentrated gas to dissipate,
PROCEDURES: use ventilation to dissipate the gas into the atmosphere. Leaks

should be quickly repaired, particularly in confined spaces. Use
appropriate personal protective equipment.
WASTE DISPOSAL METHOD: Gases may be vented slowly to a well ventilated outdoor location
remote from personnel work areas and building air intakes. Do not
dispose of any residual gas in compressed gas cylinders. Return
the cylinders to the supplier with residual pressure.
7. HANDLING AND STORAGE
STORAGE TEMPERATURE: Must be stored with all the precautions necessary for safety with
any nonflammable, nontoxic, compressed gas.
SHELF LIFE: Indefinite.
HANDLING / STORAGE Krypton/Xenon must be handled with all the precautions necessary
PRECAUTIONS: for safe handling any nonflammable, nontoxic, compressed gas.
8. EXPOSURE CONTROLS / PERSONAL PROTECTION
RECOMMENDED WORK / Follow safe work practices and precautions necessary for safety
HYGIENE PROCEDURES: when using a nonflammable, nontoxic, compressed gases.
EYE PROTECTION Chemical splash goggles or faceshield is advised to protect against
REQUIREMENTS: the extremely cold gas.
HAND PROTECTION Cold gases can cause frostbite injury upon contact with the hands.
REQUIREMENTS: Hand protection such as insulated gloves shall be worn to prevent
contact with cold gas or equipment and piping.
PROTECTIVE CLOTHING Cold gases can cause frostbite injury upon contact with the skin.
REQUIREMENTS: Clothing shall be worn to prevent contact with cold gas or
equipment and piping.
RESPIRATORY Positive pressure supplied air or self contained breathing apparatus
REQUIREMENTS: is recommended for oxygen deficient atmospheres. Such
equipment should be located conveniently to the place of work, but
kept out of the area most likely to be contaminated. All respiratory
equipment should be used consistent with OSHA 29 CFR
1910.134. Upper limit: Follow manufacturer's recommendations.

11. TOXICOLOGICAL INFORMATION
ROUTES OF ENTRY: Inhalation
EFFECTS OF ACUTE Krypton / Xenon are simple asphyxiants. Air (oxygen) is
EXPOSURE: displaced by Krypton / Xenon. As inert gases, they has no
specific toxicity effect except to exclude oxygen from the
lungs. The effect of simple asphyxiant gases is proportional
to the extent to which they diminish the amount (partial
pressure) of oxygen in the air that is breathed. The oxygen
may be diminished to 75% of it's normal percentage in air
before appreciable symptoms develop. This in turn requires
the presence of a simple asphyxiant in a concentration of
33% in the mixture of air and gas. When the simple
asphyxiant reaches a concentration of 50%, marked
symptoms can be produced. A concentration of 75% is fatal
in a matter of minutes.
SYMPTOMS: The first symptoms produced by a simple asphyxiant are
rapid respirations and air hunger. Mental alertness is
diminished and muscular coordination is impaired. Later
judgment becomes faulty and all sensations are depressed.
Emotional instability often results and fatigue occurs rapidly.
As the asphyxia progresses, there may be nausea and
vomiting, prostration and loss of consciousness, and finally
convulsions, deep coma and death.
EYE EFFECTS: Nontoxic, noncorrosive, no effects noted.
SKIN EFFECTS: Nontoxic, noncorrosive, no effects noted.
ACUTE INHALATION Simple asphyxiant.
EFFECTS:
CHRONIC EFFECTS / This agent is not considered a carcinogen by the NTP,
CARCINOGENICITY: IARC, or OSHA.
ORGANS AFFECTED BY
LONG-TERM EXPOSURE: A simple asphyxiant.
12. ECOLOGICAL INFORMATION
Krypton, xenon are rare atmospheric gases and as such are non-toxic and are chemically inert.
The extreme cold temperature (-244oC) will freeze organisms on contact, but no long term
ecological effects are anticipated.

13. DISPOSAL CONSIDERATIONS
When disposal becomes necessary, vent gas slowly to a well-ventilated outdoor location remote
from personnel work areas and building air intakes. Do not dispose of any residual gas in
compressed gas cylinders. Return cylinders to the supplier with residual pressure, the cylinder
valve tightly closed.
Please be advised that state and local requirements for waste disposal may be more restrictive or
otherwise different from federal regulations. Consult state and local regulations regarding the
proper disposal of this material.
