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.
6002FR 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; or fatality from gross overexposure. 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

# 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-404A is not flammable in air at temperatures up to 100
deg C (212 deg F) at atmospheric pressure. However,
mixtures of R-404A with high concentrations of air at
elevated pressure and/or temperature can become combustible
in the presence of an ignition source. R-404A can also
become combustible in an oxygen enriched environment (oxygen
concentrations greater than that in air). Whether a mixture
containing R-404A and air, or R-404A 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-404A should not be allowed to exist with air above
atmospheric pressure or at high temperatures; or in an
oxygen enriched environment. For example: R-404A 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 using forced ventilation, especially in 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.
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.
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.

TOXICOLOGICAL INFORMATION
----------------------------------------------------------------------
Animal Data
The blend is untested.
HFC-125
Inhalation 4 hour ALC: > 709,000 ppm in rats
Single, high inhalation exposures caused lethargy, decreased
activity, labored breathing and weight loss. Weak cardiac
sensitization effect, a potentially fatal disturbance of
heart rhythm caused by a heightened sensitivity to the
action of epinephrine. Lowest-Observed-Adverse-Effect-Level
for cardiac sensitization: 100,000 ppm.
Repeated exposure caused: No significant toxicological
effects. No-Observed-Adverse-Effect-Level(NOAEL): 50,000 ppm
No animal data are available to define carcinogenic,
developmental or reproductive hazards. In animal testing
this material has not caused developmental toxicity.
HFC-125 does not produce genetic damage in bacterial or
mammalian cell cultures or when tested in animals (not
tested for heritable genetic damage).
HFC-134a
Inhalation 4-hour LC50: 567,000 ppm in rats
Single exposure caused: Cardiac sensitization, a potentially
fatal disturbance of heart rhythm associated with a
heightened sensitivity to the action of epinephrine.
Lowest-Observed-Adverse-Effect-Level for cardiac
sensitization: 75,000 ppm. Single exposure caused: Lethargy.
Narcosis. Increased respiratory rates. These effects were
temporary. Single exposure to near lethal doses caused:
Pulmonary edema. Repeated exposure caused: Increased
adrenals, liver, spleen weight. Decreased uterine, prostate
6002FR DuPont Page 7
Material Safety Data Sheet
(TOXICOLOGICAL INFORMATION - Continued)
weight. Repeated dosing of higher concentrations caused:
the following temporary effects - Tremors. Incoordination.
CARCINOGENIC, DEVELOPMENTAL, REPRODUCTIVE,MUTAGENIC EFFECTS:
In a two-year inhalation study, HFC-134a, at a concentration
of 50,000 ppm, produced an increase in late-occurring benign
testicular tumors, testicular hyperplasia and testicular
weight. The no-effect-level for this study was 10,000 ppm.
Animal data show slight fetotoxicity but only at exposure
levels producing other toxic effects in the adult animal.
Reproductive data on male mice show: No change in
reproductive performance. Tests have shown that this
material does not cause genetic damage in bacterial or
mammalian cell cultures, or in animals. In animal testing,
this material has not caused permanent genetic damage in
reproductive cells of mammals (has not produced heritable
genetic damage).
HFC-143a
Inhalation 4-hour LC50: >540,000 ppm in rats
Single exposures by inhalation to 500,000 ppm caused
anesthesia but no mortality at 540,000 ppm. Cardiac
sensitization occurred in dogs at 300,000 ppm following an
intravenous challenge with epinephrine. Two, 4-week
inhalation have been conducted. In the first study,
pathological changes in the testes were observed at all
exposure concentrations; no effects were observed in
females. The testicular effect was considered related to
the method used to expose the rats to HFC-143a. In the
second study using the same exposure concentrations, no
effects were noted in males at any concentration. Data from
a 90-day study revealed no effects in male or female rats at
exposures up to 40,000 ppm. Long-term exposure caused
significantly decreased body weights in male rats fed 300
mg/kg for 52 weeks, but there was no effect on mortality.
Tests in rats demonstrated no carcinogenic activity when
administered orally 300 mg/kg/day for 52 weeks and observed
for an additional 73 weeks. Tests in bacterial cell
cultures demonstrated mutagenic activity, but the compound
did not induce transformation of mammalian cells in culture
or in the whole animal. Tests in animals demonstrate no
developmental toxicity.
