# Potential Health Effects
ADDITIONAL HEALTH EFFECTS
ACUTE OR IMMEDIATE EFFECTS: ROUTES OF ENTRY AND SYMPTOMS
INGESTION: Not a probable route of exposure.
SKIN: Contact with maleic anhydride vapour will cause severe skin
irritation. Contact with resin may cause mild irritation of skin.
EYE: Contact with maleic anhydride vapour will cause severe eye
irritation. Contact with resin may cause mild irritation of eyes.
INHALATION: Contact with maleic anhydride vapour will cause
severe nose and throat irritation.
This maleic anhydride modified polyethylene polymer may produce
volatile skin, eye or respiratory irritants on thermal processing.
The atmosphere and dust contained in the packaging may cause
similar irritation.
Overexposure may cause allergic respiratory reaction.
Avoid inhalation of stagnant air in closed container of polymer
and contact with dust on container lid.
CHRONIC EFFECTS: None known.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: None known.
MALEIC ANHYDRIDE (RESIDUAL)
Skin contact with Maleic Anhydride may cause skin burns or
ulceration. Significant skin permeation, and systemic toxicity,
after contact appears unlikely. There are inconclusive or
unverified reports of human sensitization.
Eye contact with Maleic Anhydride may cause eye corrosion with
corneal or conjunctival ulceration. Exposure to the vapors may
cause tearing, blurring of vision, sensitivity to light, or
inflammation of the eyelids.
BYN042 DuPont Page 3
Material Safety Data Sheet
(HAZARDS IDENTIFICATION - Continued)
Inhalation of Maleic Anhydride may cause headaches, nausea,
irritation or ulceration of the upper respiratory passages;
workers have reported nasal irritation after a one minute exposure
to 1.5 ppm. This compound may cause asthma-like reactions with
shortness of breath, wheezing, or cough. Higher overexposures may
cause pulmonary edema (body fluid in the lungs) with cough,
wheezing, abnormal lung sounds, possibly progressing to severe
shortness of breath and bluish discoloration of the skin.
Symptoms may be delayed. Prompt medical attention is required.
Ingestion of Maleic Anhydride may cause severe burns of the mouth
and tissues of the upper gastrointestinal tract with severe pain,
bleeding, vomiting, diarrhea and collapse of blood pressure.
Prolonged or gross overexposures may cause abnormal kidney
function as detected by laboratory tests.
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 exposed to fumes from overheating or combustion, move to fresh
air. Consult a physician if symptoms persist.
SKIN CONTACT
In case of contact, immediately wash skin with soap and water.
Wash contaminated clothing before reuse.
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
No specific intervention is indicated as compound is not likely to
be hazardous by ingestion. Consult a physician if necessary.

FIRE FIGHTING MEASURES
----------------------------------------------------------------------
Flammable Properties
Autoignition : 350 C (662 F) (Approx.)
Fire and Explosion Hazards:
UNUSUAL FIRE, EXPLOSION HAZARDS: Failure or malfunction of
temperature control systems on processing equipment such as
extruders, may create explosion hazards.
Potential electrostatic build-up when pouring pellets; grounding
of equipment recommended.
UNUSUAL FIRE, EXPLOSION HAZARDS The solid polymer can be
combusted only with difficulty. An electrostatic charge can
potentially build up when pouring pellets. Grounding of equipment
is recommended.
HAZARDOUS COMBUSTION PRODUCTS: Complete combustion gives
carbon dioxide and water. Incomplete combustion gives in
addition carbon monoxide, hydrocarbon oxidation products
including organic acids, aldehydes and alcohols, acrolein.
Extinguishing Media
Water, carbon dioxide, Foam, Dry Chemical.
Fire Fighting Instructions
Keep personnel removed and upwind of fire. Wear self-contained
breathing apparatus (SCBA) and full protective equipment.
Polyethylene resins are combustible materials. Molten
polyethylene tends to flow or drip and will propagate fire.
----------------------------------------------------------------------
ACCIDENTAL RELEASE MEASURES
----------------------------------------------------------------------
Safeguards (Personnel)
NOTE: Review FIRE FIGHTING MEASURES and HANDLING (PERSONNEL)
sections before proceeding with clean-up. Use appropriate
PERSONAL PROTECTIVE EQUIPMENT during clean-up.
Spill Clean Up
Sweep up to avoid slipping hazard.

Material Safety Data Sheet
----------------------------------------------------------------------
HANDLING AND STORAGE
----------------------------------------------------------------------
Handling (Personnel)
See FIRST AID and PERSONAL PROTECTIVE EQUIPMENT SECTIONS.
Storage
Store in a well ventilated area away from heat and sunlight.
Keep containers tightly closed to prevent moisture absorption and
contamination.
----------------------------------------------------------------------
EXPOSURE CONTROLS/PERSONAL PROTECTION
----------------------------------------------------------------------
Engineering Controls
VENTILATION: Local exhaust system recommended for high
temperature processing and open resin handling system.
Avoid breathing or otherwise contacting vapor especially during
initial opening of container and liner.
Personal Protective Equipment
EYE/FACE PROTECTION
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, or heated
molded parts, wear heat resistant clothing, gloves and footwear.

TOXICOLOGICAL INFORMATION
----------------------------------------------------------------------
Animal Data
Maleic Anhydride
Skin absorption LD50: 2620 mg/kg in rabbits
Oral LD50 : 235 mg/kg (10% solution in corn oil) female
rats
Maleic Anhydride is corrosive to the skin and eyes. Tests for
skin sensitization have produced positive and negative results in
animals.
No deaths occurred when rats were exposed to by inhalation to
saturated vapors of maleic anhydride for 8 hours. Repeated or
long-term exposure of rats, hamsters or monkeys to this material
caused eye, nose, and lung irritation; reduced weight gain was
noted at the higher concentrations. Evidence of respiratory
sensitization was observed in guinea pigs.
Repeated ingestion of capsules containing Maleic Anhydride caused
severe gastrointestinal corrosion. Animals fed diets containing
high doses of this material showed pathological changes to the
kidney and altered urine analysis. In a different repeated dose
ingestion study in rats fed Maleic Anhydride effects were observed
in the liver, kidneys, and heart.
Animal testing indicates that Maleic Anhydride does not have
carcinogenic, developmental, or reproductive effects.
Maleic Anhydride did not produce genetic damage in bacterial
cultures or in animals. It does produce genetic damage in
mammalian cell cultures. It has not been tested for heritable
genetic damage.
