HAZARDS IDENTIFICATION
----------------------------------------------------------------------
Potential Health Effects
Inhalation of high concentrations of vapor is harmful and
may cause heart irregularities, unconsciousness, or death.
Intentional misuse or deliberate inhalation may cause death
without warning. Vapor reduces oxygen available for
breathing and is heavier than air. Liquid contact can cause
frostbite.
6037FR DuPont Page 2
Material Safety Data Sheet
(HAZARDS IDENTIFICATION - Continued)
HUMAN HEALTH EFFECTS:
Overexposure to the vapors by inhalation may include
temporary nervous system depression with anesthetic effects
such as dizziness, headache, confusion, incoordination, and
loss of consciousness. Higher exposures to the vapors may
cause temporary alteration of the heart鈥檚 electrical
activity with irregular pulse, palpitations, or inadequate
circulation. Gross overexposure may be fatal. Skin contact
with the liquid may cause frostbite.
Individuals with preexisting diseases of the central nervous
or cardiovascular system may have increased susceptibility
to the toxicity of increased exposures.
Carcinogenicity Information
None of the components present in this material at concentrations
equal to or greater than 0.1% are listed by IARC, NTP, OSHA or ACGIH
as a carcinogen.
----------------------------------------------------------------------
FIRST AID MEASURES
----------------------------------------------------------------------
First Aid
INHALATION
If inhaled, immediately remove to fresh air. Keep person calm.
If not breathing, give artificial respiration. If breathing is
difficult, give oxygen. Call a physician.
SKIN CONTACT
Flush area with lukewarm water. Do not use hot water. If
frostbite has occurred, call a physician.
EYE CONTACT
In case of contact, immediately flush eyes with plenty of water
for at least 15 minutes. Call a physician.
INGESTION
Not a probable route. However, in case of accidental ingestion,
call a physician.
Notes to Physicians
THIS MATERIAL MAY MAKE THE HEART MORE SUSCEPTIBLE TO
ARRHYTHMIAS. Catecholamines such as adrenaline, and other
compounds having similar effects, should be reserved for
emergencies and then used only with special caution.

FIRE FIGHTING MEASURES

# Flammable Properties
Flash Point : No flash point
Flammable Limits in Air, % by Volume:
LEL : None per ASTM E681
UEL : None per ASTM E681
Autoignition: Not determined
Fire and Explosion Hazards:
Cylinders may 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 color of torch flames. 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.
R-407C is not flammable in air at temperatures up to 100
deg C (212 deg F) at atmospheric pressure. However,
mixtures of R-407C with high concentrations of air at
elevated pressure and/or temperature can become combustible
in the presence of an ignition source. R-407C can also
become combustible in an oxygen enriched environment (oxygen
concentrations greater than that in air). Whether a mixture
containing R-407C and air, or R-407C in an oxygen enriched
atmosphere becomes combustible depends on the
inter-relationship of 1) the temperature 2) the pressure,
and 3) the proportion of oxygen in the mixture. In general,
R-407C should not be allowed to exist with air above
atmospheric pressure or at high temperatures; or in an
oxygen enriched environment. For example: R-407C should
NOT be mixed with air under pressure for leak testing or
other purposes.
Experimental data have also been reported which indicate
combustibility of HFC-134a, a component in this blend, in
the presence of chlorine.
Extinguishing Media
As appropriate for combustibles in area.
Fire Fighting Instructions
Cool cylinder with water spray or fog. Self-contained
breathing apparatus (SCBA) is required if cylinders rupture
and contents are released under fire conditions. Water
runoff should be contained and neutralized prior to release.

----------------------------------------------------------------------
ACCIDENTAL RELEASE MEASURES
----------------------------------------------------------------------
Safeguards (Personnel)
NOTE: Review FIRE FIGHTING MEASURES and HANDLING (PERSONNEL)
sections before proceeding with clean-up. Use appropriate
PERSONAL PROTECTIVE EQUIPMENT during clean-up.
Accidental Release Measures
Ventilate area, especially low or enclosed places where
heavy vapors might collect. Remove open flames. Use
self-contained breathing apparatus (SCBA) for large spills
or releases.
----------------------------------------------------------------------
HANDLING AND STORAGE
----------------------------------------------------------------------
Handling (Personnel)
Avoid breathing vapor. Avoid liquid contact with eyes and
skin. Use with sufficient ventilation to keep employee
exposure below recommended limits. Contact with chlorine or
other strong oxidizing agents should also be avoided. See
Fire and Explosion Data section.
Storage
Clean, dry area. Do not heat above 52 deg C (125 deg F).
----------------------------------------------------------------------
EXPOSURE CONTROLS/PERSONAL PROTECTION
----------------------------------------------------------------------
Engineering Controls
Avoid breathing vapors. Avoid contact with skin or eyes.
Use with sufficient ventilation to keep employee exposure
below the recommended exposure limit. Local exhaust should
be used if large amounts are released. Mechanical
ventilation should be used in low or enclosed places.
Personal Protective Equipment
Impervious gloves should be used to avoid prolonged or
repeated exposure. Chemical splash goggles should be
available for use as needed to prevent eye contact. Under
normal manufacturing conditions, no respiratory protection
is required when using this product. Self-contained
breathing apparatus (SCBA) is required if a large release
occurs.
