8. HEALTH HAZARD DATA
-----------------------------------------------------------------------------

EYE CONTACT:
Mild Eye Irritation: signs/symptoms can include redness, swelling,
pain, and tearing.

SKIN CONTACT:
Product is not expected to be irritating to the skin.

May be absorbed through the skin and produce effects similiar to
those caused by inhalation and/or ingestion.

INHALATION:
Single overexposure, above recommended guidelines, may cause:

Irritation (upper respiratory): signs/symptoms can include
soreness of the nose and throat, coughing and sneezing.

IF SWALLOWED:
Animal studies conducted on organic fluorochemicals which are present
in this product indicate effects including liver disturbances, weight
loss, loss of appetite, lethargy, and neurological, pancreatic,
adrenal and hematologic effects. There are no known human health
effects from anticipated exposure to these organic fluorochemicals
when used as intended and instructed.

OTHER HEALTH HAZARD INFORMATION:
This product contains one or more organic fluorochemicals that have
the potential to be absorbed and remain in the body for long periods
of time, either as the parent molecule or as metabolites, and may
accumulate with repeated exposures. There are no known human health

effects from anticipated exposure to these organic fluorochemicals
when used as intended and instructed.

The presence of organic fluorochemicals in the blood of the general
population and subpopulations, such as workers, has been published
dating back to the 1970's. 3M's epidemiological study of its own
workers indicates no adverse effects.
