SECTION 5. FIREFIGHTING MEASURES
Suitable extinguishing media
: Use extinguishing measures that are appropriate to local circumstances and
the surrounding environment.
Unsuitable extinguishing
media
: No applicable data available.
Specific hazards
: 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.
Special protective equipment
for firefighters
: In the event of fire, wear self-contained breathing apparatus. Use personal
protective equipment. Wear neoprene gloves during cleaning up work after a
fire.

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.

: 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

Lower explosion limit
: Method : None per ASTM E681
Upper explosion limit
: Method : None per ASTM E681
Fire and Explosion Hazard
: 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.

Material Safety Data Sheet
DuPont™ ISCEON® MO29™ refrigerant
Version 2.2
Revision Date 09/12/2011
Ref. 130000027389
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.
Firefighting Instructions
: In the event of fire, wear self-contained breathing apparatus. Wear neoprene
gloves during cleaning up work after a fire.
Use extinguishing measures that are appropriate to local circumstances and
the surrounding environment. Cool containers / tanks with water spray.
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.
Spill Cleanup
: Ventilate area using forced ventilation, especially low or enclosed places
where heavy vapors might collect. Recover free liquid for reuse or
reclamation.
Accidental Release Measures
: Prevent material from entering sewers, waterways, or low areas.
Avoid open flames and high temperatures. Self-contained breathing
apparatus (SCBA) is required if a large release occurs.
