Components
Material :CAS : Number: %
ETHANE, 1,1-DIFLUORO- (HFC 152a) 75-37-6 100
----------------------------------------------------------------------
----------------------------------------------------------------------
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 heartÕs
electrical
activity with irregular pulse, palpitations,
or inadequate
circulation, or abnormal kidney function as
detected by
laboratory tests. Gross overexposure may be
fatal.
(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
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.

DuPont Page 3
(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.
----------------------------------------------------------------------
----------------------------------------------------------------------
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).

----------------------------------------------------------------------
----------------------------------------------------------------------
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.
----------------------------------------------------------------------
----------------------------------------------------------------------
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.
Exposure Guidelines
Exposure Limits
"DYMEL" 152a AEROSOL PROPELLANT
PEL (OSHA) : None Established
TLV (ACGIH) : None Established
AEL * (DuPont) : 1000 ppm, 8 Hr. TWA
WEEL (AIHA) : 1000 ppm, 8 Hr. TWA
* AEL is DuPontÕs Acceptable Exposure Limit.
Where governmentally
imposed occupational exposure limits which are
lower than the AEL
are in effect, such limits shall take
precedence.

and high
temperatures.
Incompatibility with Other Materials
Incompatible with alkali or alkaline earth
metals- powdered
Al, Zn, Be, etc.
Polymerization
Polymerization will not occur.
Other Hazards

hazardous.
This material can be decomposed by high
temperatures (open flames, glowing metal
surfaces, etc.) forming hydrofluoric acid
and possibly carbonyl fluoride.
----------------------------------------------------------------------
----------------------------------------------------------------------
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.
Page 6
(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.

Waste Disposal
Reclaim by distillation, incinerate, or remove
to a
permitted waste facility. Comply with Federal,
State, and
local regulations.
This material may be a RCRA Hazardous waste
upon disposal
due to the ignitability characteristic.
