HAZARDS IDENTIFICATION
----------------------------------------------------------------------
Potential Health Effects
Inhalation of HFC-152a may cause nonspecific discomfort such
as nausea, headache or weakness, or temporary nervous system
depression with dizziness, confusion, incoordination,
drowsiness or unconsciousness.
Higher exposures may lead to irritation of nose, throat, and
lungs with cough, difficulty breathing or shortness of
breath, temporary alteration of the heart鈥檚 electrical
activity with irregular pulse, palpitations, or inadequate
circulation, or abnormal kidney function as detected by
laboratory tests. Gross overexposure may be fatal.
3027FR DuPont Page 2
Material Safety Data Sheet
(HAZARDS IDENTIFICATION - Continued)
Individuals with preexisting diseases of the central nervous
system, cardiovascular system, lungs or kidney 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 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. 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 be used
with special caution only in situations of emergency life
support.

UEL : 16.9
Autoignition : 454 C (849 F)
3027FR DuPont Page 3
Material Safety Data Sheet
(FIRE FIGHTING MEASURES - Continued)
Fire and Explosion Hazards:
Flammable. Cylinders are equipped with temperature and
pressure relief devices but may still rupture under fire
conditions. Use water spray to cool cylinders and tanks.
HFC-152a fire decomposition by-products will include
hydrofluoric acid, and possibly carbonyl fluoride. Avoid
contact with these materials, which are toxic and
irritating. Evacuate personnel immediately in the event of a
fire involving HFC-152a.
Extinguishing Media
Water Spray, Water Fog, Dry Chemical.
Carbon dioxide. "Alcohol" foam.
Fire Fighting Instructions
Keep container cool with water spray. If gas exiting
container ignites, stop flow of gas. Do not put out the
fire unless leak can be stopped immediately. Self-contained
breathing apparatus (SCBA) is required if containers 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
If a spill can cause a concentration in excess of 1,000 ppm,
turn off valves and ignition sources. Evacuate area.
Ventilate area, especially low places where heavy vapors
might collect. Wear self-contained breathing apparatus
(SCBA).
If this product is spilled and not recovered, or is
recovered as a waste for treatment or disposal, the CERCLA
Reportable Quantity is 100 lbs. (Release of an unlisted
Hazardous Waste characteristic of ignitability).
3027FR DuPont Page 4
Material Safety Data Sheet
----------------------------------------------------------------------
HANDLING AND STORAGE
----------------------------------------------------------------------
Handling (Personnel)
Avoid breathing high concentrations of vapors and avoid
liquid contact with skin or eyes. Use with sufficient
ventilation to keep employee exposure below recommended
limits. Lines and equipment which will contain "DYMEL" 152a
Aerosol Propellant should be pretested with nitrogen using
soapy water to detect leaks.
Storage
Clean, dry area. Do not heat above 52 deg C 125 deg 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 exhaust should be used in
low or enclosed places. Ground all equipment and cylinders
before use. Use explosion-proof electrical equipment rated
Class I, Group D in Division 1 locations. In Division 2
locations, all spark-producing electrical equipment must be
explosion-proof and rated Class I, Group D. Non-sparking
motors need not be explosion-proof.
Personal Protective Equipment
Impervious gloves and chemical splash goggles should be worn
when handling the liquid. Fire protective clothing (NOMEX)
with antistatic control should be worn when handling this
product. 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
Oral ALD: >1500 mg/kg in rats
Inhalation ALC, 4 hr: 383,000 ppm in rats
HFC-152a has not been tested for skin and eye irritancy, nor
for animal sensitization.
Ingestion of single high doses of HFC-152a caused weight
loss and lethargy.
3027FR DuPont Page 6
Material Safety Data Sheet
(TOXICOLOGICAL INFORMATION - Continued)
Inhalation of high levels of HFC-152a caused labored
breathing, lung irritation, lethargy, incoordination and
loss of consciousness. Cardiac sensitization occurred in
dogs exposed to a concentration of 150,000 ppm in air and
given an intravenous epinephrine challenge.
Repeated inhalation exposures caused increased urinary
fluoride, reduced kidney weight, and reversible kidney
changes. Based on an independent peer review the reversible
kidney changes are considered artifacts of the tissue and
slide processing and not a compound related effect.
Animal testing demonstrate no carcinogenic activity nor
developmental effects. No animal data are available to
define reproductive effects of HFC-152a.
HFC-152a has not produced genetic damage in bacterial
cultures. There are reports indicating that HFC-152a
produced genetic damage in some mammalian cell culture
tests. A weak genotoxic effect in germ cells of Drosophila
melanogaster has been reported. It has not been tested in
animals.
