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 can cause death
without warning. Vapor reduces oxygen available for
breathing and is heavier than air. Liquid contact can cause
frostbite.
2075FR 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 inhalation overexposures to
the vapors may cause temporary alteration of the heart鈥檚
electrical activity with irregular pulse, palpitations, or
inadequate circulation. Fatality from gross overexposure
may occur. Skin contact with the liquid may cause
frostbite.
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.
----------------------------------------------------------------------
FIRST AID MEASURES
----------------------------------------------------------------------
First Aid
INHALATION
If large amounts are inhaled, immediately remove to fresh
air. Keep persons calm. If not breathing, give
artificial respiration. If breathing is difficult, give
oxygen. Call a physician.
SKIN CONTACT
In case of skin contact, flush with water for 15 minutes.
Treat for frostbite if necessary by gently warming
affected area.
EYE CONTACT
In case of eye contact, immediately flush eyes with
plenty of water for 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 be used
with special caution only in situations of emergency life
support.

or release 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 places where heavy vapors
might collect. Remove open flames. Use self-contained
breathing apparatus (SCBA) for large spills. 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 recommended limits.
Storage
Clean, dry area. Do not heat above 52 deg C (125 deg F).

Material Safety Data Sheet
----------------------------------------------------------------------
EXPOSURE CONTROLS/PERSONAL PROTECTION
----------------------------------------------------------------------
Engineering Controls
Use with sufficient ventilation to keep employee exposure
below recommended exposure limits. Local exhaust should be
used when large amounts are released. Mechanical
ventilation should be used in low or enclosed places.
Personal Protective Equipment
Impervious gloves and chemical splash goggles should be used
if contact is possible. Under normal manufacturing
conditions, no respiratory protection is required when using
this product. Self-contained breathing apparatus (SCBA) is
required if a spill or release occurs.

TOXICOLOGICAL INFORMATION
----------------------------------------------------------------------
Animal Data
"FREON" 115
Inhalation 4-hour LC50: >800,000 ppm in rats
Oral ALD : >1200 mg/kg in rats
The effects of a single inhalation exposure at high
concentrations include rapid respiration and inactivity.
Repeated exposure at lower levels produced no signs of
toxicity. Exposure to 150,000 ppm with simultaneous
epinephrine challenge produced cardiac arrhythmia in dogs.
The effects of repeated ingestion include mild diarrhea,
salivation and increased activity.
No animal test reports are available to define carcinogenic
developmental or reproductive hazards. The compound does
not produce genetic damage in bacterial cell cultures but
has not been tested in animals.
"FREON" 22
Inhalation 4-hour LC50: 220,000 ppm in rats
The compound is a skin irritant and a slight eye irritant,
but is not a skin sensitizer in animals.
2075FR DuPont Page 6
Material Safety Data Sheet
(TOXICOLOGICAL INFORMATION - Continued)
Effects from single high exposures include central nervous
system depression, anesthesia, rapid breathing, lung
congestion and microscopic liver changes. Cardiac
sensitization occurred in dogs at 50,000 ppm or greater from
the action of exogenous epinephrine.
No toxic effects or abnormal histopathological observations
occurred in rats repeatedly exposed to concentrations
ranging from 10,000 to 50,000 ppm (v/v). Long-term
exposures to 50,000 ppm (v/v) of vapors produced organ
weight increases and a decrease in body weight gain, but no
increased mortality or adverse hematological effects.
In chronic inhalation studies, HCFC-22, at a concentration
of 50,000 ppm (v/v), produced a small, but statistically
significant increase of late-occurring tumors involving
salivary glands in male rats, but not female rats or male
or female mice. In the same studies, no increased
incidence of tumors was seen in either species at
concentrations of 10,000 ppm or 1000 ppm (v/v).
Long-term administration in corn oil produced no effects
on body weight or mortality.
HCFC-22 was mutagenic in some strains of bacteria in
bacterial cell cultures, but not mammalian cell cultures
or animals. It did not cause heritable genetic damage in
mammals.
A slight, but significant increase in developmental
toxicity was observed at high concentrations (50,000 ppm)
of HCFC-22, a concentration which also produced toxic
effects in the adult animal. Based on these findings, and
other negative developmental studies, HCFC-22 is not
considered a unique hazard to the conceptus. Studies of
the effects of HCFC-22 on male reproductive performance
have been negative. Specific studies to evaluate the
effect on female reproductive performance have not been
conducted, however, limited information obtained from
studies on developmental toxicity do not indicate adverse
effects on female reproductive performance at
concentrations up to 50,000 ppm.
