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

(HAZARDS
IDENTIFICATION - Continued)
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.

Hazards
Decomposition:
Heating above 260-290 deg C (500-554 deg F)
may
form potentially toxic fluorine compounds.
Depolymerization

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.
