HAZARDS IDENTIFICATION
Potential Health Effects INHALATION
ETHANE, 1,1,1,2-TETRAFLUORO-
Gross overexposure may cause: Central nervous system depression
with dizziness, confusion, incoordination, drowsiness or
unconsciousness. Irregular heart beat with a strange sensation in
the chest, "heart thumping", apprehension, lightheadedness,
feeling of fainting, dizziness, weakness, sometimes progressing to
loss of consciousness and death. Suffocation, if air is displaced
by vapors.
SKIN CONTACT
ETHANE, 1,1,1,2-TETRAFLUORO-
Immediate effects of overexposure may include: Frostbite, if
liquid or escaping vapor contacts the skin.
EYE CONTACT
ETHANE, 1,1,1,2-TETRAFLUORO-
"Frostbite-like" effects may occur if the liquid or escaping
vapors contact the eyes.
ADDITIONAL HEALTH EFFECTS
ETHANE, 1,1,1,2-TETRAFLUORO-
Increased susceptibility to the effects of this material may be
observed in persons with pre-existing disease of the: central
nervous system, cardiovascular system.
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 high concentrations are 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
In case of contact, immediately flush skin with plenty of water
for at least 15 minutes, while removing contaminated clothing and
shoes. Call a physician. Wash contaminated clothing before
reuse. 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. Call a physician.
INGESTION
Ingestion is not considered a potential route of exposure.
Notes to Physicians
Because of possible disturbances of cardiac rhythm, catecholamine
drugs, such as epinephrine, should only be used with special
caution in situations of emergency life support.
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 : >743 C(>1369 F)
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.
HFC-134a is not flammable in air at temperatures up to
100 deg. C (212 deg. F) at atmospheric pressure. However,
mixtures of HFC-134a with high concentrations of air at
elevated pressure and/or temperature can become combustible
in the presence of an ignition source. HFC-134a can
also become combustible in an oxygen enriched environment
(oxygen concentrations greater than that in air). Whether a
mixture containing HFC-134a and air, or HFC-134a 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, HFC-134a should not be allowed to exist with
air above atmospheric pressure or at high temperatures; or
in an oxygen enriched environment. For example HFC-134a
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 in the presence of certain
concentrations of chlorine.
Extinguishing Media
Use media appropriate for surrounding material.
Fire Fighting Instructions
Cool tank/container with water spray. Self-contained breathing
apparatus (SCBA) may be required if cylinders rupture or release
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.
Ventilate area, especially low or enclosed places where heavy
vapors might collect. Remove open flames. Use self-contained
breathing apparatus (SCBA) if large spill or leak occurs.
HANDLING AND STORAGE
Handling (Personnel)
Use with sufficient ventilation to keep employee exposure below
recommended limits.
Handling (Physical Aspects)
HFC-134a should not be mixed with air for leak testing or used for
any other purpose above atmospheric pressure. See Flammable
Properties section. Contact with chlorine or other strong
oxidizing agents should also be avoided.
Storage
Store in a clean, dry place. Do not heat above 52 C (126 F).
EXPOSURE CONTROLS/PERSONAL PROTECTION
Engineering Controls
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.
Personal Protective Equipment
Impervious gloves and chemical splash goggles should be used when
handling liquid.
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.

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).
