HAZARDS IDENTIFICATION
Potential Health Effects
Skin contact
may cause skin irritation with discomfort or
rash. Prolonged
skin contact may cause redness and
inflammation
of the hair follicles without skin
sensitization.
Eye contact
may cause eye irritation with discomfort,
tearing or
blurring of vision.
Inhalation
of fluorine compounds released as decomposition
products above
290 degC (554 degF) may cause lung irritation
and pulmonary
edema which require medical treatment.
Inhalation
of fumes or smoke from overheated or burning
grease may
cause polymer fume fever, a temporary flu-like
illness accompanied
by fever, chills, and sometimes cough,
of approximately
24 hours duration. Repeated episodes of
polymer fume
fever may cause lung damage.
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,
remove to fresh air. 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.
INGESTION
If swallowed,
do not induce vomiting. Immediately give 2 glasses
of water. Never
give anything by mouth to an unconscious person.
Call a physician.
Notes to Physicians
Activated charcoal
mixture may be administered. To prepare
activated charcoal
mixture, suspend 50 grams activated charcoal
in
400 mL water
and mix thoroughly. Administer 5 mL/kg, or 350 mL
for an average
adult.
FIRE FIGHTING MEASURES

with eyes. Avoid contact with skin. Wash
thoroughly
after handling. Do not store or consume food, drink
or
tobacco in
areas where they may become contaminated with this
material.
Storage
Keep container
tightly closed. Do not store or consume food,
drink or tobacco
in areas where they may become contaminated with
this material.

product.
EXPOSURE CONTROLS/PERSONAL PROTECTION
Engineering Controls
Keep container
tightly closed.
Keep away from
heat and flames.
Personal Protective Equipment
EYE/FACE PROTECTION
Wear safety
glasses or coverall chemical splash goggles.
RESPIRATOR
Where the potential
exists for exposure to decomposition
products due
to heating or elevated temperatures, wear
NIOSH approved
respiratory protection as appropriate.
PROTECTIVE
CLOTHING
Where there
is potential for skin contact have available
and wear as
appropriate, impervious gloves, apron, pants,
and jacket.
Exposure Guidelines
Applicable Exposure Limits
PTFE
PEL (OSHA) : None Established
TLV (ACGIH) : None Established
AEL * (DuPont) : 10 mg/m3, 8 Hr. TWA, total dust
5
mg/m3, 8 Hr. TWA, respirable dust
* AEL is DuPont's
Acceptable Exposure Limit. Where
governmentally
imposed occupational
exposure limits which are lower than the AEL
are in effect,
such limits shall take precedence.

Incompatibility with Other Materials
None reasonably
foreseeable.
Polymerization
Polymerization
will not occur.
Other Hazards
Decomposition: Heating above 260-290 deg C (500-554 deg F)
may form potentially
toxic fluorine compounds.
Depolymerization
may occur in the presence of some metal
oxides at temperatures
above 288 deg C (550 deg F).

355 deg C (670 deg F).
TOXICOLOGICAL INFORMATION
Animal Data
Perfluoroalkylether:
Inhalation
4 hour ALC: 19.54 mg/l in rats
Skin
absorption ALD: >17,000 mg/kg in rats
Oral
ALD: >25,000
mg/kg in rats
The product
contains a mild eye irritant. A single
inhalation
exposure to perfluoroalkylether caused
nonspecific
effects such as respiratory irritation. Toxic
effects described
in animals exposed to decomposition
products of
perfluoroalkylether formed above 260 degC (500
degF) include
lung irritation, irregular respiration,
tremors and
increased liver weight. Pulmonary edema and
death occurred
in rats exposed to the decomposition products
of perfluoroalkylether
formed at around 290 degC (554 degF).
A single inhalation
exposure to PTFE caused irritation of
the lungs. A repeated ingestion exposure caused no
significant
toxicological effects. Long-term ingestion
exposure caused
altered white blood cell count.
DISPOSAL CONSIDERATIONS
Waste Disposal
Treatment,
storage, transportation, and disposal must be in
accordance
with applicable Federal, State/Provincial, and Local
regulations. Do not flush to surface water or sanitary sewer
system.
