3. HAZARD IDENTIFICATION
EMERGENCY OVERVIEW : This gas mixture is a colorless, odorless gas. Releases of this gas mixture for which Nitrogen is the balance gas
may produce oxygen-deficient atmospheres (especially in confined spaces or other poorly-ventilated environments); individuals in such
atmospheres may be asphyxiated. Components of this gas mixture (1,1,2-Trichloro-1,1,2-trifluoroethane, Tetrafluoromethane,
Trichlorofluoromethane, and Dichlorodifluoromethane) may cause drowsiness and other central nervous system effects in high concentrations;
however, due to their low concentration in this gas mixture, this is unlikely to occur. If components of this gas mixture (1,1,2-Trichloro-1,1,2-
trifluoroethane, Tetrafluoromethane, Trichlorofluoromethane, and Dichlorodifluoromethane) are exposed to fire, they may decompose yielding
toxic products (i.e. hydrogen fluoride, phosgene, hydrogen chloride, carbonyl fluoride).
SYMPTOMS OF OVER-EXPOSURE BY ROUTE OF EXPOSURE : The most
significant route of over-exposure for this gas mixture is by inhalation.
INHALATION : Due to the small size of an individual cylinder of this gas mixture, no
unusual health effects from over-exposure to the product are anticipated under
routine circumstances of use. The chief health hazard associated with this gas
mixture for which Nitrogen is the balance gas and is released in a small, poorly-
ventilated area (i.e. an enclosed or confined space) is the development of an oxygen-
deficient environment. Individuals breathing such an atmosphere may experience
symptoms which include headaches, ringing in ears, dizziness, drowsiness,
unconsciousness, nausea, vomiting, and depression of all the senses. Under some
circumstances of over-exposure, death may occur. The effects associated with
various levels of oxygen are as follows:
CONCENTRATION OF OXYGEN OBSERVED EFFECT
12-16% Oxygen: Breathing and pulse rate increased,
muscular coor-dination slightly disturbed.
10-14% Oxygen: Emotional upset, abnormal fatigue,
disturbed respiration.
6-10% Oxygen: Nausea, vomiting, collapse, or loss of
consciousness.
Below 6%: Convulsive movements, possible
respiratory collapse, and death.

See Section 8
HEALTH EFFECTS OR RISKS FROM EXPOSURE: An Explanation in Lay Terms .
Over-exposure to this gas mixture may cause the following health effects:
ACUTE : Due to the small size of the individual cylinder of this gas mixture, no unusual health effects from exposure to the product are anticipated
under routine circumstances of use. The most significant hazard associated with this gas mixture when it contains less than 19.5% oxygen is the
potential for exposure to oxygen-deficient atmospheres. Symptoms of oxygen deficiency include respiratory difficulty, ringing in ears, headaches,
shortness of breath, wheezing, headache, dizziness, indigestion, nausea, unconsciousness, and death. The skin of a victim of over-exposure may
have a blue color.
CHRONIC : Chronic exposure to oxygen-deficient atmospheres (below 18% oxygen in air) may effect the heart and nervous system.
TARGET ORGANS : ACUTE: Respiratory system, eyes. CHRONIC: Heart, cardiovascular system, central nervous system, reproductive system.
4. FIRST-AID MEASURES
RESCUERS SHOULD NOT ATTEMPT TO RETRIEVE VICTIMS OF EXPOSURE TO THIS GAS MIXTURE WITHOUT ADEQUATE PERSONAL
PROTECTIVE EQUIPMENT. If necessary, Self-Contained Breathing Apparatus must be worn.
No unusual health effects are anticipated after exposure to this gas mixture, due to the small cylinder size. If any adverse symptom develops after
over-exposure to this gas mixture, remove victim(s) to fresh air as quickly as possible. Only trained personnel should administer supplemental
oxygen and/or cardio-pulmonary resuscitation if necessary. Victim(s) who experience any adverse effect after over-exposure to this gas mixture
must be taken for medical attention. Rescuers should be taken for medical attention if necessary. Take a copy of the label and the MSDS to
physician or other health professional with victim(s).
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: Acute or chronic respiratory conditions may be aggravated by over-exposure to the
components of this gas mixture.
RECOMMENDATIONS TO PHYSICIANS: Administer oxygen, if necessary; treat symptoms; eliminate exposure. Note: Epinephrine increases the
toxicity of Chlorodifluoromethane on the heart.

FLAMMABLE LIMITS (in air by volume, %):
Lower (LEL): Not applicable.
Upper (UEL): Not applicable.
FIRE EXTINGUISHING MATERIALS : Non-flammable gas mixture. Use extinguishing
media appropriate for surrounding fire.
UNUSUAL FIRE AND EXPLOSION HAZARDS : This gas mixture is not flammable;
however, containers, when involved in fire, may rupture or burst in the heat of the fire.
Additionally, mixtures of this gas for which Air is the balance gas, can support
combustion.
Explosion Sensitivity to Mechanical Impact: Not sensitive.
Explosion Sensitivity to Static Discharge: Not sensitive.
SPECIAL FIRE-FIGHTING PROCEDURES : Structural firefighters must wear Self-
Contained Breathing Apparatus and full protective equipment. If water is not available
for cooling or protection of cylinder exposures, evacuate the area.
6. ACCIDENTAL RELEASE MEASURES
LEAK RESPONSE : Due to the small size and content of the cylinder, an accidental release of this gas mixture presents significantly less risk of an
oxygen-deficient environment 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. Such 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. Allow the gas mixture to dissipate. If necessary, monitor the surrounding area (and the original area of the release) for oxygen.
Oxygen levels must be above 19.5% before non-emergency personnel are allowed to re-enter area.
If leaking incidentally from the cylinder, contact your supplier.
7. HANDLING and USE
WORK PRACTICES AND HYGIENE PRACTICES: Be aware of any signs of dizziness or fatigue, especially if work is done in a poorly-ventilated
area; exposures to fatal concentrations of this gas mixture could occur without any significant warning symptoms, due to oxygen deficiency. Do not
attempt to repair, adjust, or in any other way modify cylinders containing this gas mixture. If there is a malfunction or another type of operational
problem, contact nearest distributor immediately.
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, well-
ventilated areas, away from sources of heat, ignition, and direct sunlight. Protect cylinders against physical damage.
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 significant 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 that application equipment is locked and tagged-out safely. Always use product in areas where adequate
ventilation is provided.
