Potential Health Effects
ADDITIONAL HEALTH EFFECTS
Before using "HYPALON" Synthetic Rubber, read Bulletin
HPE-H68551-00-D1102 "Toxicity and Handling Guide".
CHLOROSULFONATED POLYETHYLENE
ACUTE OR IMMEDIATE EFFECTS: ROUTES OF ENTRY AND SYMPTOMS
INGESTION Not a probable route of exposure. The oral LD-50 of
"HYPALON" in rats is greater than 20,000 mg/kg.
SKIN Skin contact, especially with hot polymer, may cause skin
irritation in some sensitive people resulting in redness, itching,
and in extreme cases, blistering. Avoid contact with hot polymer
which may give thermal burns.
EYE Polymer chips in the eye will cause mechanical damage
including scratching of the cornea.
INHALATION The polymer itself is not respirable as marketed.
Polymer contains residual carbon tetrachloride which may be
released during storage. There are no symptoms for exposure to
low levels of carbon tetrachloride released over a long period of
time except, if the PEL is exceeded, liver damage may result.
Vapors released during processing will be composed of hydrogen
chloride, sulfur dioxide and possibly carbon monoxide. If these
gases are evolved, they will cause tearing and burning of the
eyes. The vapors will also cause irritation to the upper
respiratory tract which results in a sore throat and coughing in
severe cases with shortness of breath.
CHRONIC EFFECTS Carbon tetrachloride and chloroform have been
classified by IARC and NTP as carcinogens based on tests with
laboratory animals. Exposure to carbon tetrachloride at
concentrations above the PEL may cause liver damage.
MEDICAL CONDTIONS AGGRAVATED BY EXPOSURE Exposure to carbon
tetrachloride will aggravate cirrhosis of the liver.
TALC
Short-term over-exposure by inhalation to Talc may cause
irritation of the nose, throat and lungs with cough, difficulty
breathing or shortness of breath. Long-term over-exposure may
lead to chronic lung disease with impaired lung function and
abnormal chest x-rays.
Increased susceptibility to the effects of Talc may be observed in
persons with pre-existing disease of the lungs.

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
The compound is not likely to be hazardous by skin contact but
cleansing the skin after use is advisable.
If molten material gets on skin, cool rapidly with cold water. Do
not attempt to remove material from skin. Obtain medical treatment
for thermal burn.
EYE CONTACT
In case of contact, immediately flush eyes with plenty of water
for at least 15 minutes. Call a physician.
INGESTION
Not a probable route. However, in case of accidental ingestion,
call a physician.

Shovel or sweep up.
----------------------------------------------------------------------
HANDLING AND STORAGE
----------------------------------------------------------------------
Handling (Personnel)
See FIRST AID and PERSONAL PROTECTIVE EQUIPMENT SECTIONS.
Storage
Store in a cool, dry place. Storage and work areas should be
monitored for carbon tetrachloride to assure that the PEL is not
exceeded.
----------------------------------------------------------------------
EXPOSURE CONTROLS/PERSONAL PROTECTION
----------------------------------------------------------------------
Engineering Controls
VENTILATION Local ventilation is required to keep the
concentration of carbon tetrachloride below the PEL. Local
ventilation is required over processing equipment to keep the
concentration of gases which are irritating to the eyes and upper
respiratory system below recommended values.
Personal Protective Equipment
EYE/FACE PROTECTION
HYP001 DuPont Performance Elastomers L.L.C. Page 5
Material Safety Data Sheet
(EXPOSURE CONTROLS/PERSONAL PROTECTION - Continued)
Wear safety glasses. Wear coverall chemical splash goggles and
face shield when possibility exists for eye and face contact due
to splashing or spraying of molten material. A full face mask
respirator provides protection from eye irritation.
RESPIRATORS
A NIOSH/MSHA approved air purifying respirator with an organic
vapor cartridge with a dust/mist filter may be permissible under
certain circumstances where airborne concentrations are expected
to exceed exposure limits. Protection provided by air purifying
respirators is limited. Use a positive pressure air supplied
respirator if there is any potential for an uncontrolled release,
exposure levels are not known, or any other circumstances where
air purifying respirators may not provide adequate protection.
PROTECTIVE CLOTHING
If there is potential contact with hot/molten material, wear heat
resistant clothing and footwear.

TOXICOLOGICAL INFORMATION
----------------------------------------------------------------------
Animal Data
TALC
Talc
Oral LD50: 920 mg/kg in rats
Inhalation 5 hour ALC: > 22 mg/L in rats
Long-term exposure by ingestion to Talc caused no significant
decrease in life span.
HYP001 DuPont Performance Elastomers L.L.C. Page 7
Material Safety Data Sheet
(TOXICOLOGICAL INFORMATION - Continued)
A single exposure by inhalation to high doses of Talc caused
irregular respiration and lacrimation but no evidence of an
inflammatory reaction. Repeated exposure caused no adverse
effects on survival or histological changes. Long-term exposure
in rats caused chronic inflammation, impaired pulmonary function
and histopathological changes of the lungs.
One lifetime inhalation study reports an increased incidence of
lung and adrenal tumors in rats exposed to Talc. The lung tumors
and chronic inflammation occured at dust levels which overwhelmed
the animals lung clearance mechanism and, therefore, are of
questionable biological relevance for man. The adrenal tumors are
unlikely to be a direct effect of Talc exposure and are of
questionable relevance. No increases in tumors were observed in
mice. Talc has not caused developmental toxicity in animals. No
animal data are available to define the reproductive toxicity of
Talc. Tests have shown that Talc does not cause genetic damage in
bacterial or mammalian cell cultures, or in animals. Animal data
indicate that Talc does not cause permanent genetic damage in
reproductive cells of mammals (does not cause heritable genetic
damage).
