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.
HUMAN HEALTH EFFECTS:
Skin contact may cause frostbite from exposure to the
liquid.
Inhalation may include nonspecific discomfort, such as
nausea, headache, or weakness; or temporary nervous system
depression with anesthetic effects such as dizziness,
headache, confusion, incoordination, and loss of
consciousness.
Gross overexposure may cause: Central nervous system
depression with drowsiness or unconsciousness; irregular
heart beat with a strange sensation in the chest, "heart
thumping", apprehension, lightheadedness and feeling of
fainting.
Higher exposures (>20%) may lead to these effects:
temporary lung irritation effects with cough, discomfort,
difficulty breathing, or shortness of breath; temporary
alteration of the heart鈥檚 electrical activity with irregular
pulse, palpitations, or inadequate circulation; abnormal
kidney function as detected by laboratory tests; or fatality
from gross overexposure.
"Frostbite-like" effects may occur if the liquid or escaping
vapors contact the eyes.
Individuals with preexisting diseases of the central nervous
system, cardiovascular system, lungs or kidneys may have
increased susceptibility to the toxicity of excessive
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.

Material Safety Data Sheet
----------------------------------------------------------------------
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
Flush skin with water for at least 15 minutes after
excessive contact. Treat for frostbite if necessary by
gently warming affected area. Seek medical assistance if
irritation is present. Wash contaminated clothing before
reuse.
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 - Continued)
Fire Fighting Instructions
Use water spray to cool containers. Self-contained
breathing apparatus (SCBA) may be required if cylinders
rupture and contents are released under fire conditions.
----------------------------------------------------------------------
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. Comply
with Federal, State, and local regulations for reporting
releases.
----------------------------------------------------------------------
HANDLING AND STORAGE
----------------------------------------------------------------------
Handling (Personnel)
Avoid breathing vapors. Avoid liquid contact with skin or
eyes. Use with sufficient ventilation to keep employee
exposure below the recommended limit.
Storage
Clean, dry area. Do not heat above 52 deg C (125 deg F).
----------------------------------------------------------------------
EXPOSURE CONTROLS/PERSONAL PROTECTION
----------------------------------------------------------------------
Engineering Controls
Use with sufficient ventilation to keep employee exposure
below the recommended exposure limit. Local exhaust should
be used when large amounts are released. Mechanical
ventilation should be used for 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.
