HAZARDS IDENTIFICATION
----------------------------------------------------------------------
Potential Health Effects
INHALATION
ETHANE, 2-CHLORO-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, 2-CHLORO-1,1,1,2-TETRAFLUORO-
Immediate effects of overexposure may include: Frostbite, if
liquid or escaping vapor contacts the skin.
EYE CONTACT
ETHANE, 2-CHLORO-1,1,1,2-TETRAFLUORO-
"Frostbite-like" effects may occur if the liquid or escaping
vapors contact the eyes.
ADDITIONAL HEALTH EFFECTS
ETHANE, 2-CHLORO-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
2200FR DuPont Page 3
Material Safety Data Sheet
(FIRST AID MEASURES - Continued)
Flush skin with water for at least 15 minutes after excessive
contact. Seek medical assistance if irritation is present. 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.
----------------------------------------------------------------------

Material Safety Data Sheet
----------------------------------------------------------------------
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.
Spill Clean Up
Comply with Federal, State, and local regulations for reporting
releases.
----------------------------------------------------------------------
HANDLING AND STORAGE
----------------------------------------------------------------------
Handling (Personnel)
Avoid breathing vapors or mist. Avoid contact with eyes or skin.
Use with sufficient ventilation to keep employee exposure below
recommended limits.
Storage
Store in a clean, dry place. Do not heat above 52 C (126 F).
----------------------------------------------------------------------
EXPOSURE CONTROLS/PERSONAL PROTECTION
----------------------------------------------------------------------
Engineering Controls
Use sufficient ventilation to keep employee exposure below
recommended limits. Local exhaust should be used when large
amounts are released. Mechanical ventilation should be used in
low or enclosed places.
Personal Protective Equipment
Lined butyl 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.

Additional Information
HCFC-124 is TSCA-listed but its use is controlled by a TSCA
Section 5, Significant New Use Rule (SNUR); 40 CFR 721.3180. The
SNUR prohibits the commercial use of HCFC-124 as a blowing agent
in the manufacture of structural insulation foams for commercial
or consumer purposes. Activity related to this application is
therefore limited to technical research and development conducted
in accordance with the requirements of the R&D Exemption of the
TSCA PMN regulations. Refer to 40 CFR 720.36 for further details
on the requirements of this Exemption. All other uses of HCFC-124
are permitted.
