3. HAZARDS IDENTIFICATION


EMERGENCY OVERVIEW

KEVLAR? brand engineered elastomer is a yellowish solid material; it is either in a granular form
(1Kxxxx merges), or in a nugget shape (1Fxxxx merges.) As shipped, this product poses no safety or
environmental hazard.

POTENTIAL HEALTH EFFECTS:

During processing at high temperatures, the product may produce fumes that may cause eye and
respiratory irritation. Use with adequate ventilation.

When mechanically working materials containing KEVLAR? in operations such as cutting, machining,
grinding, crushing or sanding, airborne respirable fibrils may be formed. Repeated and prolonged
inhalation of excessive concentration of respirable fibers may cause permanent lung injury.
(Reference: KEVLAR? Aramid Fiber MSDS.)

FOR NEOPRENE PRODUCTS - CHRONIC EFFECTS

During processing and curing, neoprene may produce small amounts of N-nitrosodiethylamine and
N-nitrosodibutylamine. These materials are classified as carcinogens by NTP. In the laboratory,
local exhaust kept the nitrosamine concentration in air below 40 parts per trillion.

FOR NATURAL RUBBER PRODUCTS - CHRONIC EFFECTS

Natural rubber may produce allergic reactions in some individuals following skin contact; skin contact
with engineered elastomer merge 1F722 should be minimized.

MSDS SP6018: KEVLAR?? brand engineered elastomer Revised: February 6, 2006



Antigenic latex protein levels in samples of engineered elastomer in natural rubber matrix, as
analyzed by ASTM method D5712-95, were below the limit of detection for the method.

CARCINOGENICITY INFORMATION

IARC classified p-aramid respirable fibrils as Group 3, "not classifiable as to carcinogenicity in
humans," in October 1996. That is, after reviewing all published toxicological literature on p-aramid,
they found no convincing evidence of carcinogenicity. [See the ??TOXICOLOGICAL INFORMATION??
section and references contained in the ??OTHER INFORMATION?? section of this MSDS.

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.



4. FIRST AID MEASURES


INHALATION

If irritating fumes are inhaled, remove to fresh air. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen. Call a physician.

SKIN CONTACT

Wash with soap and water. 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 eye contact, immediately flush eyes with plenty of water for at least 15 minutes. Call a
physician if irritation persists or develops later.

INGESTION

Not a probable route of exposure.




5. FIRE FIGHTING MEASURES

FLAMMABLE PROPERTIES

KEVLAR? brand engineered elastomer can be burned only with difficulty.

Hazardous gases/vapors produced in a fire are carbon monoxide, carbon dioxide, hydrogen
cyanide, oxides of nitrogen, and small amounts of aromatic and aliphatic hydrocarbons.

For Neoprene products, hydrogen chloride and sulphur dioxide are also produced.

EXTINGUISHING MEDIA

Water, Foam, or Dry Chemical. CO2 is not generally recommended for Class A fires as a lack of
cooling capacity may result in reignition.

MSDS SP6018: KEVLAR?? brand engineered elastomer Revised: February 6, 2006



FIRE FIGHTING INSTRUCTIONS

Keep personnel removed and upwind of fire. Wear self-contained breathing apparatus.
Wear full protective equipment.



6. 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

Recover undamaged and uncontaminated KEVLAR? brand engineered elastomer for reuse and
reclamation. Sweep up to avoid slipping hazard.




7. HANDLING AND STORAGE

HANDLING (Personnel)

Avoid contact with eyes, skin, or clothing. Wash thoroughly after handling. Do not store or consume
food, drink, or tobacco in areas where they may become contaminated with this material.

Avoid contact with fumes generated during processing. Abnormal processing conditions or
equipment failure during processing may cause decomposition. Personnel involved in cleaning
decomposed or decomposing material should wear suitable air-supplied respirators.

Many ingredients used in rubber compounds require special handling. It is the users responsibility to
understand and follow recommended precautions for other compounding ingredients as defined by
their suppliers.

STORAGE

Keep container tightly closed. Store in a well-ventilated cool, dry area away from heat and sunlight.

Certain Neoprene grades are sensitive to heat history. G-type neoprene will react adversely to
extended storage above room temperature. The severity of effects will increase as storage
temperature increases. For example, G-types that have been stored for as little as 2-3 weeks at 38??
C can show marked viscosity changes. An appropriate storage temperature is 18?? C. G-types stored
at 18?? C will remain in generally usable condition up to a year.

First in, first out inventory control should be employed.

8. EXPOSURE CONTROLS/PERSONAL PROTECTION


ENGINEERING CONTROLS

Keep containers of KEVLAR? brand engineered elastomer tightly closed.

Avoid dust generation.

Ventilation: Use local exhaust ventilation over processing equipment. Where processing
may release excessive dust or fumes, maintain respirable dust and fumes below
control limits.

PERSONAL PROTECTIVE EQUIPMENT

EYE/FACE PROTECTION

Wear safety glasses.

RESPIRATION PROTECTION

Respirator use must be in accordance with OSHA Standard 29 CFR 1910.134 (the ??Respirator
Standard??).

PROTECTIVE CLOTHING
Wear protective gloves and a long sleeved shirt when handling hot polymers.

EXPOSURE GUIDELINES

Applicable Exposure Limits
Para-aramid Respirable Fibrous Particulate (RFP)
PEL (OSHA) : None established
TLV (ACGIH) : None Established
AEL * (DuPont) : 2 fibers/cc, 8 Hr. TWA, respirable fibrils
< 3 ??m in diameter, > 5 ??m in length, and with an
aspect ratio > 3:1.
5 mg/m3, total dust for non-respirable fibers or non-
fibrous particulate.
Elastomer Matrix
PEL (OSHA) : None established
TLV (ACGIH) : None Established
10 mg/m3, 8 Hr. TWA, total dust
AEL * (DuPont) :
5 mg/m3, 8 Hr. TWA, respirable dust

* AEL is DuPont's Acceptable Exposure Limit. Where governmentally imposed occupational
exposure limits which are lower than the AEL are in effect, such limits shall take precedence.

11. TOXICOLOGICAL INFORMATION

There is no toxicology information on KEVLAR? brand engineered elastomer.

See references for toxicology of natural rubber.

As with all chemicals for which test data are limited or do not exist, caution must be exercised through
the prudent use of protective equipment and handling procedures to minimize exposure.

If processing produces significant dust levels, see the MSDS for KEVLAR? for toxicology of respirable
fibrous dust.


12. ECOLOGICAL INFORMATION

ECOTOXICOLOGICAL INFORMATION

Toxicity is expected to be low based on the materials' negligible water solubility.



13. DISPOSAL CONSIDERATIONS

WASTE DISPOSAL

KEVLAR? brand engineered elastomer is not a hazardous waste as defined by regulations
implementing the Resource Conservation and Recovery Act.

In general KEVLAR? brand engineered elastomer waste materials may be treated, stored,
transported, and disposed of in accordance with State and Local regulations governing the
disposal of other common or non-RCRA regulated waste material.

If the product is incinerated, provisions to remove acidic gases should be employed.

If waste material is ground, use engineering controls where technically feasible such as isolation,
enclosures, exhaust ventilation, wetting, or dust collection systems wherever necessary to control
airborne respirable KEVLAR? aramid fibrous dust exposures.
