Potential
Health Effects
Skin
contact may cause skin irritation with discomfort or
rash.
Prolonged skin contact to perfluoroalkylether may
cause
redness and inflammation of the hair follicles without
skin
sensitization. Sodium nitrite has been infrequently
associated
with skin sensitization in humans.
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.
Ingestion
or inhalation of sodium nitrite may cause low
blood
pressure with a throbbing headache and fainting; or
nonspecific
discomfort such as nausea or weakness.
Overexposure
to sodium nitrite may cause methemoglobinemia
(reduced
oxygen carrying capacity of the blood) with
headache,
weakness, or cyanosis (bluish discoloration of the
skin),
possibly progressing to dizziness, incoordination,
shortness
of breath, increased pulse rate and loss of
consciousness.
Simultaneous
ingestion of nitrites and medications or
chemicals
containing an amine group may form carcinogenic
nitrosamines
in the stomach.
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.

TOXICOLOGICAL
INFORMATION

Animal
Data
Perfluoroalkylether:
Inhalation

Oral

Oral
LD50: 120 mg/kg in rats
The
product contains mild eye irritants. A single inhalation
exposure
to perfluoroalkylether caused nonspecific effects
such
as respiratory irritation. Toxic effects described in
animals
exposed to decomposition products of perfluoroalkyl-
ether
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). Other than increased
activity
of lung enzymes, no toxic effects were observed in
animals
exposed to sodium nitrite by inhalation. By
ingestion,
sodium nitrite produced methemoglobinemia,
decreased
hemoglobin, increased brain dopamine and
nonspecific
effects such as weight loss and irritation. Long
term
ingestion of sodium nitrite produced methemoglobinemia
and
unspecified pathological changes in the liver, spleen,
kidney,
adrenals, brain, heart and lungs. A similar product
is
of very low toxicity by ingestion.
Tests
in animals indicate that sodium nitrite is not
carcinogenic.
Tests of sodium nitrite under circumstances in
which
nitrosamines, a chemical group with some known
carcinogens,
could have been formed demonstrate carcinogenic
activity.
Tests of sodium nitrite for mutagenic activity in
bacterial
or mammalian cell cultures have been inconclusive
with
positive results in some tests, and negative results in
others
but produces genetic damage in animals. Tests of
sodium
nitrite in animals demonstrate no reproductive or
developmental
activity.
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.
