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
6122FR DuPont Page 2
Material Safety Data Sheet
(HAZARDS IDENTIFICATION - Continued)
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.
Hexamethyldisiloxane may be harmful by inhalation,
ingestion, or skin absorption. Vapor or mist is irritating
to the mucous membranes and upper respiratory tract; vapor
overexposure may cause drowsiness. Repeated or prolonged
skin contact may cause defatting of the skin leading to
dermatitis. Eye contact may cause eye irritation with
redness and swelling. Ingestion may be harmful; ingestion of
large amounts may cause drowsiness.
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 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 while removing contaminated
clothing and shoes. Call a physician. Wash contaminated
clothing before reuse.

Material Safety Data Sheet
(FIRST AID MEASURES - Continued)
EYE CONTACT
In case of contact, immediately flush eyes with plenty of
water for at least 15 minutes. Call a physician.
INGESTION
Material poses an aspiration hazard. If swallowed, do not
induce vomiting. Immediately give 2 glasses of water.
Never give anything by mouth to an unconscious person. Call
a physician.
If vomiting occurs naturally, have victim lean forward to
reduce the risk of aspiration.
Notes to Physicians

----------------------------------------------------------------------
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
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.
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.

Material Safety Data Sheet
----------------------------------------------------------------------
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 manual or
flammable rated drum pump is recommended for dispensing from
shipping containers.
Storage
Store in 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
----------------------------------------------------------------------

TOXICOLOGICAL INFORMATION
----------------------------------------------------------------------
Animal Data
HFC-43-10mee:
Oral LD50: > 5,000 mg/kg in rats
Dermal ALD: > 5,000 mg/kg in rabbits
Inhalation, 4 hour LC50: 11,100 ppm in rats
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.
Hexamethyldisiloxane:
Hexamethyldisiloxane is a mild skin irritant in animals.
Ingestion caused systemic irritation in rats. Inhalation
6122FR DuPont Page 8

(TOXICOLOGICAL INFORMATION - Continued)
caused depression and increased liver and kidney weights;
eye and respiratory tract irritation, anorexia and cyanosis
in animals. Tests have shown that this material does not
cause genetic damage in bacterial and mammalian cell
cultures or in animals.
