HAZARDS IDENTIFICATION
----------------------------------------------------------------------
Potential Health Effects

Gross overexposure by inhalation to HFC-43-10mee may cause
suffocation if air is displaced by vapors and central
nervous system stimulation with increased activity or
sleeplessness, tremors or convulsions. These effects may be
followed by central nervous system depression with
dizziness, confusion, incoordination, drowsiness or
unconsciousness. Based on data from other fluorocarbons,
gross overexposure may be associated with irregular
heartbeat or heart rhythm, which may produce heart
palpitation, dizziness, weakness, unconsciousness and death.
It is unlikely that concentrations sufficient to produce
irregular heartbeat or heart rhythm would be achieved from
HFC-43-10MEE without first producing other signs of
toxicity. Immediate effects of overexposure to HFC-43-10mee
by skin contact may include slight irritation with itching,
redness or swelling. Repeated and/or prolonged exposure may
cause defatting of the skin with itching, redness or rash.
Based on animal data, significant skin permeation, and
systemic toxicity after skin contact, appears unlikely.
Immediate effects of overexposure to HFC-43-10mee by eye
contact may include eye irritation with tearing, pain or
blurred vision. The major ingestion hazard of HFC-43-10mee
is aspiration (liquid entering the lungs during ingestion or
vomiting) which may result in "chemical pneumonia." Symptoms
include coughing, gasping, choking, shortness of breath,
bluish discoloration of the skin, rapid breathing and heart
rate, and fever. Pulmonary edema or bleeding, drowsiness,
confusion, coma and seizures may occur in more serious
cases. Symptoms may develop immediately or as late as 24
hours after exposure, depending on how much chemical entered
the lungs. Increased susceptibility to the effects of
HFC-43-10mee may be observed in persons with pre-existing
disease of the central nervous system or the cardiovascular
system.

Inhalation of t-DCE may cause central nervous system
depression with dizziness, confusion, incoordination,
drowsiness or unconsciousness; or tremors, nausea, vomiting,
weakness, and abdominal cramps. Other effects may include
irregular heart beat with a strange sensation in the chest,
"heart thumping",apprehension, lightheadedness, feeling of
fainting, dizziness, or weakness. Skin contact with t-DCE
may cause severe irritation with burning, redness, swelling,
pain or rash. Eye contact with t-DCE may cause severe eye
irritation with tearing, pain or blurred vision. Ingestion
of t-DCE may cause pulmonary edema (body fluid in the lungs)
with cough, wheezing, abnormal lung sounds, possibly
progressing to severe shortness of breath and bluish
discoloration of the skin: symptoms may be delayed.
Ingestion may also cause pathological changes in the liver,
central nervous system depression with dizziness, confusion,
6155FR DuPont Page 3
Material Safety Data Sheet

(HAZARDS IDENTIFICATION - Continued)

incoordination, drowsiness or unconsciousness, and
structural (pathological) changes in heart muscle tissue.

Inhalation of Cyclopentane may cause central nervous system
depression with dizziness, confusion, incoordination,
drowsiness or unconsciousness; and non-specific effects such
as headache, nausea and weakness. Repeated and/or prolonged
exposure may cause peripheral nervous system effects with
tingling, pain, or loss of sensation in extremities which
may by accompanied by weakness or loss of muscle control.
Higher exposures may cause "heart thumping", apprehension,
lightheadedness, feeling of fainting, dizziness, weakness,
sometimes progressing to loss of consciousness and death.
Skin contact with Cyclopentane may cause defatting of the
skin with itching, redness or rash. Eye contact with liquid
or high vapor concentrations of Cyclopentane may cause eye
irritation with tearing, pain or blurred vision. Ingestion
of Cyclopentane may cause gastrointestinal irritation with
pain or diarrhea. The major ingestion hazard is aspiration
(liquid entering the lungs during ingestion or vomiting)
which may result in "chemical pneumonia". Symptoms include
coughing, gasping, choking, shortness of breath, bluish
discoloration of the skin, rapid breathing and heart rate,
and fever. Pulmonary edema or bleeding, drowsiness,
confusion, coma and seizures may occur in more serious
cases. Symptoms may develop immediately or as late as 24
hours after exposure, depending on how much chemical entered
the lungs. Increased susceptibility to the effects of
Cyclopentane may be observed in persons with pre-existing
disease of the central nervous or cardiovascular systems.

The fatal dose of Methyl Alcohol by ingestion is from 60 to
250 ml. Inhalation of Methyl Alcohol may cause irritation of
the nose and throat with sneezing, sore throat or runny
nose. Skin contact with Methyl Alcohol may cause irritation
with itching, burning, redness, swelling or rash. Skin
permeation may occur in amounts capable of producing the
effects of systemic toxicity. Eye contact with Methyl
Alcohol may cause eye irritation with tearing, pain or
blurred vision. Ingestion of Methyl Alcohol may cause
irritation of the digestive tract with stomach pain,
heartburn, nausea, vomiting or diarrhea; however there may
be no symptoms at all. Inhalation, ingestion or skin contact
with Methyl Alcohol may cause temporary mild depression of
the central nervous system with dizziness, confusion,
incoordination or drowsiness followed by an asymptomatic
period usually ranging from 12 to 24 hours. Metabolic
acidosis develops followed by ocular toxicity (visual
disturbance including blindness). Other effects include
non-specific effects such as headache, nausea and weakness.
Gross overexposure may cause pathological changes in the
liver and kidneys; nerve damage with numbness, weakness or
muscle rigidity; tremors; convulsions; and fatality.
Increased susceptibility to the effects of Methyl Alcohol
6155FR DuPont Page 4

(HAZARDS IDENTIFICATION - Continued)

may be observed in persons with pre-existing disease of the
nervous system, visual system, liver, kidneys, and
cardiovascular system.

Short-term overexposure by inhalation to Nitromethane may
cause irritation of the nose and throat with sneezing, sore
throat or runny nose. Based on animal data repeated and/or
prolonged exposure may cause irritation of nose, throat, and
lungs with cough, difficulty breathing or shortness of
breath, pathological changes in the liver, central nervous
system depression with dizziness, confusion, incoordination,
drowsiness or unconsciousness, peripheral nervous system
effects with tingling, pain, or loss of sensation in
extremities which may be accompanied by weakness or loss of
muscle control, altered blood cell counts, impaired
functioning of the blood-forming system with alterations in
blood cell counts and/or anemia, effects on the nervous
tissue, and clinical pathological changes of the thyroid.
Skin contact with Nitromethane may cause skin irritation
with itching, burning, redness, swelling or rash. Eye
contact with Nitromethane may cause eye irritation with
tearing, pain or blurred vision. Based on animal data,
ingestion of Nitromethane may cause abnormal liver function
with altered enzyme levels in blood, or abnormal kidney
function with altered results on blood tests.

FIRST AID MEASURES
----------------------------------------------------------------------
First Aid

INHALATION

If 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 after contact. 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.
6155FR DuPont Page 5
Material Safety Data Sheet

(FIRST AID MEASURES - Continued)

INGESTION

If swallowed, immediately give 2 glasses of water and induce
vomiting. Never give anything by mouth to an unconscious person.
Call a physician.

Notes to Physicians

Ethanol (ETOH) is antidotal and should be administered early in
the treatment. Ethanol is a potent inhibitor of Methanol
metabolism because it is preferentially acted on by liver alcohol
dehydrogenase, thus delaying or preventing toxic metabolites from
Methanol.

Treatment is started after residual ingested substance is removed
from the stomach. Ethanol is administered orally or IV with a
goal of maintaining a blood alcohol level of approximately 22
mmol/L or 1.0 mg/L.

To prepare antidote, make a solution using 100 mL of 100 proof
ethyl alcohol and 1900 mL of water. Give 1.5 mL/kg or 100 mL for
an average adult. This may be mixed with orange juice for oral
use if necessary. More Ethanol is to be given at 2 hour intervals
to achieve and maintain the desired blood alcohol levels.
Treatment may be necessary for several days.

The patient should be monitored for metabolic acidosis. Use of
appropriate buffering solutions, such as bicarbonate, may be
indicated.

Hemodialysis may be required.

THIS MATERIAL MAY MAKE THE HEART MORE SUSCEPTIBLE TO ARRHYTHMIAS.
Catecholamines such as adrenaline, and other compounds having
similar effects, should be reserved for emergencies and then used
only with special caution.

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.

Initial Containment

Dike spill. Prevent material from entering sewers, waterways, or
low areas.

Spill Clean Up

Soak up with sawdust, sand, oil dry or other absorbent material.

Immediately evacuate the area and provide maximum
ventilation, especially in low places where heavy vapors
might collect. Unprotected personnel should move upwind of
spill. Only personnel equipped with proper respiratory and
skin/eye protection should be permitted in area. Soak up
with sawdust, sand, oil dry or other absorbent material.
After all visible traces, including ignitable vapors, have
been removed, thoroughly wet vacuum the area. Do not flush
to sewer. If area of spill is porous, remove as much
contaminated earth and gravel, etc. as necessary and place
in closed containers for disposal.
6155FR DuPont Page 7
Material Safety Data Sheet

(ACCIDENTAL RELEASE MEASURES - Continued)

In spill or leak situations, the composition of vapors above
the liquid may fall within the LEL/UEL and, therefore,
become flammable. Provide ventilation and assure no
ignition sources are present.

----------------------------------------------------------------------
HANDLING AND STORAGE
----------------------------------------------------------------------
Handling (Personnel)

Avoid breathing vapors or mist. Avoid contact with eyes, skin, or
clothing. Wash thoroughly after handling.

The use of gloves is recommended when working with the
material containers. Material should not be dispensed from
its container by pouring, except for small sample containers
where fume hoods or where other ventilation is used to
manage the exposure limits. The use of a drum pump is
recommended for dispensing from shipping containers.

Storage

Store in a clean, dry area. Do not allow stored product to
exceed 52 C (125 F) to prevent leakage or potential rupture
of container from pressure and expansion. Protect from
freezing temperatures. If solvent is stored below -10 C
(14 F), mix prior to use.

----------------------------------------------------------------------
EXPOSURE CONTROLS/PERSONAL PROTECTION
----------------------------------------------------------------------
Engineering Controls

Animal testing indicates that HFC-43-10mee is a slight skin
irritant and a mild eye irritant, but is not a skin
sensitizer. HFC-43-10mee did not cause cardiac sensitization
in dogs exposed to 1000 or 5000 ppm. The cardiac
sensitization potential was not evaluated at or above 10,000
ppm due to clinical signs consistent with central nervous
system toxicity. Single exposure to 5,000 ppm HFC-43-10mee
by inhalation caused tremors. A different single exposure
study by inhalation in rats caused incoordination,
hyperactivity and prostration; pathological examination of
rats from this study revealed kidney and lung changes, and
external hair loss. Repeated exposures to 1,900 - 3,500 ppm
caused tremors or convulsions, behavioral effects, and
altered clinical chemistry. In developmental toxicity
studies with laboratory animals, HFC-43-10mee was not
uniquely toxic to the developing fetus. No animal data are
available to define the carcinogenic or reproductive hazards
of HFC-43-10mee. Tests have shown that HFC-43-10mee does
not cause genetic damage in bacterial or mammalian cell
cultures. It has not produced genetic damage in tests on
animals.

t-DCE is a severe eye irritant, and a moderate to severe
skin irritant. Single and repeated exposure to t-DCE by
ingestion caused increased kidney weight, histopathological
changes of the lungs, liver effects, decreased motor
activity, pulmonary edema, cardiovascular system changes,
and mortality. Single and repeated exposure to t-DCE by
inhalation caused pathological changes of the liver and
lungs, inactivity or anaesthesia, altered white blood cell
count, cardiovascular system changes and weak cardiac
sensitization, a potentially fatal disturbance of the heart
rhythm caused by a heightened sensitivity to the action of
epinephrine. Long-term exposure caused altered liver and
lung function. A more recent inhalation study (Dec. 1998)
conducted with well-characterized t-DCE containing > 99.4%
t-DCE, produced no adverse, compound-related effects. The
NOEL was 4000 ppm. Exposure of pregnant rats shows maternal
toxicity at 2000, 6000 and 12,000 ppm. Developmental
toxicity was seen only at 12,000 ppm. Tests have shown that
t-DCE does not cause genetic damage in bacterial or
mammalian cell cultures. No animal data are available to
define the carcinogenic or reproductive hazards of t-DCE.
6155FR DuPont Page 11
Material Safety Data Sheet

(TOXICOLOGICAL INFORMATION - Continued)

Animal testing indicates that Cyclopentane is a slight skin
irritant. Single exposure by inhalation to Cyclopentane
caused inactivity or anaesthesia, altered righting reflexes,
and cardiac sensitization, a potentially fatal disturbance
of heart rhythm associated with a heightened sensitivity to
the action of epinephrine. No animal data are available to
define the carcinogenicity, developmental, reproductive or
mutagenic hazards of Cyclopentane.

Animal testing indicates Methyl Alcohol is an eye and skin
irritant. Eye contact with Methyl Alcohol caused clouding of
the eye (corneal opacity). Repeated skin contact with higher
concentrations of Methyl Alcohol caused some mortality.
Single exposure by ingestion caused narcosis, liver effects,
and hypothermia. Repeated exposure caused pathological
changes of the eyes and acidosis. Repeated exposure by
inhalation caused irritation of the eyes, and blindness. No
animal data are available to define the carcinogenicity of
Methyl Alcohol. Exposure of pregnant rats shows the
following developmental effects: reduced birth weight, bone
abnormalities, and behavioral abnormalities. Exposure of
pregnant mice shows the following developmental effects:
reduced birth weight, resorption, and bone abnormalities.
No adequate animal data are available to define the
reproductive effects of Methyl Alcohol. Tests have shown
that Methyl Alcohol does not cause genetic damage in
bacterial or mammalian cell cultures, or in animals. Methyl
Alcohol has not been tested for its ability to cause
permanent genetic damage in reproductive cells of mammals
(not tested for heritable genetic damage).

Nitromethane is a skin irritant, and a slight eye irritant,
but is not a skin sensitizer in animals. Single inhalation
exposure to Nitromethane caused upper respiratory tract
irritation, liver and kidney effects, central nervous system
depression, incoordination, eye irritation, and some
mortality. Repeated inhalation exposures caused loss of
mobility in the hind limbs, alterations to the blood-forming
system, altered hematology and clinical chemistry,
respiratory testicular effects, reduced sperm counts,
altered estrous cycle, degeneration of the sciatic nerve,
and spinal cord. Long-term exposure caused reduced weight
gain, altered hematology, increased thyroid weight,
decreased thyroxine levels and pathological changes of the
lungs. Single ingestion exposure to high doses caused
histopathological changes of the liver and kidney injury.
Repeated exposures caused reduced weight gain, and liver
injury. Repeated dermal exposure caused no significant
toxicological effects. In one study, Nitromethane produced
evidence of carcinogenic activity in male and female mice
exposed to concentrations of 188, 375, or 750 ppm for 2
years, and in female rats exposed to concentrations of 94,
188, or 375 ppm for 2 years. There was no evidence of
carcinogenic activity in male rats exposed for 2 years to
6155FR DuPont Page 12
Material Safety Data Sheet

(TOXICOLOGICAL INFORMATION - Continued)

concentrations of 94, 188, or 375 ppm. In a different
study, with male and female rats exposure to concentrations
of 100 or 200 ppm for 2 years did not produce evidence of
carcinogenic activity. No adequate animal data are available
to define the developmental or reproductive toxicity of
Nitromethane. Tests have shown that Nitromethane did not
cause genetic damage in bacterial or mammalian cell
cultures.
