Misuse or intentional inhalation abuse may cause death without warning
symptoms, due to cardiac effects.
Other symptoms potentially related to misuse or inhalation abuse are:
Anaesthetic effects, Light-headedness, dizziness, confusion,
incoordination, drowsiness, or unconsciousness, irregular heartbeat with a
strange sensation in the chest, heart thumping, apprehension, feeling of
fainting, dizziness or weakness.
Vapours are heavier than air and can cause suffocation by reducing oxygen
available for breathing.
Carcinogenicity
None of the components present in this material at concentrations equal to or greater than 0.1% are listed by
IARC, NTP, or OSHA, as a carcinogen.

SECTION 4. FIRST AID MEASURES
Skin contact
: In case of contact, immediately flush skin with plenty of water for at least 15
minutes. Take off all contaminated clothing immediately. Consult a physician.
Wash contaminated clothing before re-use. Treat for frostbite if necessary by
gently warming affected area.
Eye contact
: In case of contact, immediately flush eyes with plenty of water for at least 15
minutes. Consult a physician if necessary.
Inhalation
: Remove from exposure, lie down. Move to fresh air. Keep patient warm and
at rest. Artificial respiration and/or oxygen may be necessary. Consult a
physician.
Ingestion
: Is not considered a potential route of exposure.

General advice
: Never give anything by mouth to an unconscious person. When symptoms
persist or in all cases of doubt seek medical advice.
Notes to physician
: Because of possible disturbances of cardiac rhythm, catecholamine drugs,
such as epinephrine, that may be used in situations of emergency life support
should be used with special caution.

Ref. 130000024024
Cylinders are equipped with pressure and temperature relief devices, but may
still rupture under fire conditions. Decomposition may occur. Contact of
welding or soldering torch flame with high concentrations of refrigerant can
result in visible changes in the size and colour of the torch flame. This flame
effect will only occur in concentrations of product well above the
recommended exposure limit. Therefore stop all work and ventilate to
disperse refrigerant vapors from the work area before using any open flames.
This substance is not flammable in air at temperatures up to 100 deg. C (212
deg. F) at atmospheric pressure. However, mixtures of this substance with
high concentrations of air at elevated pressure and/or temperature can
become combustible in the presence of an ignition source. This substance
can also become combustible in an oxygen enriched environment (oxygen
concentrations greater than that in air). Whether a mixture containing this
substance and air, or this substance in an oxygen enriched atmosphere
become combustible depends on the inter-relationship of 1) the temperature
2) the pressure, and 3) the proportion of oxygen in the mixture. In general,
this substance should not be allowed to exist with air above atmospheric
pressure or at high temperatures; or in an oxygen enriched environment. For
example this substance should NOT be mixed with air under pressure for leak
testing or other purposes.
Experimental data have also been reported which indicate combustibility of
this substance in the presence of certain concentrations of chlorine.
Suitable extinguishing media
: Use extinguishing measures that are appropriate to local circumstances and
the surrounding environment.
Firefighting Instructions
: In the event of fire, wear self-contained breathing apparatus.
Cool containers / tanks with water spray. Water runoff should be contained
and neutralized prior to release.
SECTION 6. ACCIDENTAL RELEASE MEASURES
NOTE: Review FIRE FIGHTING MEASURES and HANDLING (PERSONNEL) sections before proceeding with cleanup. Use appropriate PERSONAL PROTECTIVE EQUIPMENT during clean-up.
Safeguards (Personnel)
: Evacuate personnel to safe areas. Ventilate area, especially low or enclosed
places where heavy vapours might collect.
Spill Cleanup
: Evaporates.
Accidental Release Measures
: Should not be released into the environment.

Self-contained breathing apparatus (SCBA) is required if a large release
occurs. Avoid open flames and high temperatures.
SECTION 7. HANDLING AND STORAGE
Handling (Personnel)
: Use sufficient ventilation to keep employee exposure below recommended
limits. For personal protection see section 8.
Handle in accordance with good industrial hygiene and safety practice.
Handling (Physical Aspects)
: The product should not be mixed with air for leak testing or used with air for
any other purpose above atmospheric pressure. Contact with chlorine or
other strong oxidizing agents should also be avoided.
Storage
: 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
(>3000 psig) piping or systems. Never attempt to lift cylinder by its cap. Use a
check valve or trap in the discharge line to prevent hazardous back flow into
the cylinder. Cylinders should be stored upright and firmly secured to
prevent falling or being knocked over.
Separate full containers from empty containers. Keep at temperature not
exceeding 52°C. Do not store near combustible materials. Avoid area where
salt or other corrosive materials are present.
Storage temperature
: < 52 °C (< 126 °F)
SECTION 8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Engineering controls
Personal protective equipment
Respiratory protection
: Normal ventilation for standard manufacturing procedures is generally
adequate. Local exhaust should be used when large amounts are released.
Mechanical ventilation should be used in low or enclosed places. Refrigerant
Concentration monitors may be necessary to determine vapor concentrations
in work areas prior to use of torches or other open flames, or if employees are
entering enclosed areas.
: For rescue and maintenance work in storage tanks use self-contained

by reducing oxygen available for breathing.
Hand protection
: Additional protection: Impervious gloves
Eye protection
: Wear safety glasses with side shields. Additionally wear a face shield where
the possibility exists for face contact due to splashing, spraying or airborne
contact with this material.
Protective measures
: Self-contained breathing apparatus (SCBA) is required if a large release
occurs.
