SECTION 4. FIRST AID MEASURES
Inhalation : Remove victim to fresh air and provide oxygen if breathing is
difficult. Give artificial respiration if not breathing. Get medical
attention.
Skin contact : Immediately remove contaminated clothing or shoes, wipe
excess from skin and flush with plenty of water for at least 15
minutes. Use soap if available or follow by washing with soap
and water. Do not reuse clothing until thoroughly cleaned. Get
medical attention. Contaminated leather articles, including
shoes, cannot be decontaminated and should be destroyed to
prevent reuse.
Eye contact : Immediately flush eyes with plenty of water for 15 minutes while
holding eyelids open. Get medical attention.
Ingestion : Do not induce vomiting. In general, no treatment is necessary
unless large quantites of product are ingested. However, get
medical advice.
Notes to physician
Symptoms : Irritation as noted above. Skin sensitization (allergy) may be
evidenced by rashes, especially hives.
SECTION 5. FIRE-FIGHTING MEASURES
Suitable extinguishing : Use water fog, "alcohol foam", dry chemical or carbon dioxide.
media
Specific hazards during fire : Material will not burn unless preheated. Sulfur oxides and
fighting hydrogen sulfide, both of which are toxic, may be released upon
combustion. Hydrogen halides, organo-sulfur compounds, and
other unidentified materials may be formed under fire conditions.
Cool fire exposed containers with water.
Special protective : Do not enter confined fire space without full bunker gear (helmet
equipment for fire-fighters with face shield, bunker coats, gloves and rubber boots).
including a positive pressure NIOSH approved self-contained
breathing apparatus.

SECTION 6. ACCIDENTAL RELEASE MEASURES
Personal precautions : May burn although not readily ignitable.
Use cautious judgement when cleaning up large spills.
Shut off leaks, if possible without personal risk.
Environmental precautions : Dike and contain.
Contain run-off and dispose of properly.
Prevent from entering into drains, ditches or rivers.
Clean-up methods - small : Take up with an absorbent material and dispose of properly.
spillage
Clean-up methods - large : Remove with vacuum trucks or pump to storage/salvage
spillage vessels.
Soak up residue with an absorbent such as clay, sand or other
suitable material; place in non-leaking containers for proper
disposal.
Flush area with water to remove trace residue.
Additional advice : Notify authorities if any exposures to the general public or
environment occurs or is likely to occur.
See Section 13 for information on disposal.
SECTION 7. HANDLING AND STORAGE
Handling
Advice on safe handling : Heating this curing agent above 300 Deg. F in the presence of
air may cause slow oxidative decomposition; above 500 Deg. F,
polymerization may occur. Some epoxy resins can produce
exothermic reactions which in large masses can cause runaway
polymerization and charring of the reactants. Fumes and
vapors from these thermal and chemical decompositions vary
widely in composition and toxicity. Do not breathe fumes. Keep
away from open flames and high temperatures. Use a
NIOSH-approved respirator as required to prevent
overexposure. In accord with 29 CFR.1910.134, use either an
atmosphere-supplying respirator or an air-purifying respirator for
organic vapors. WARNING. May be moderately toxic if
swallowed. May cause severe eye irritation. May cause severe
skin irritation. May cause respiratory tract irritation. May cause
skin sensitization. Containers, even those that have been
emptied, can contain hazardous product residues. Wash with
soap and water before eating, drinking, smoking, applying
cosmetics, or using toilet facilities. Launder contaminated

clothing before reuse. Contaminated leather articles, including
shoes, cannot be decontaminated and should be destroyed to
prevent reuse.
Storage
Requirements for storage : Store in a cool, dry place with adequate ventilation. Keep away
areas and containers from open flames and high temperatures.
SECTION 8. EXPOSURE CONTROLS / PERSONAL PROTECTION
Protective measures : Wear appropriate respirator and protective clothing.
Engineering measures : Use ventilation as required to control vapor concentrations.
Eye wash fountains and safety showers should be available for
emergency use.
Eye protection : Avoid contact with eyes.
Wear chemical goggles if there is potential contact with eyes.
Skin and body protection : Avoid contact with skin and clothing.
Wear chemical-resistant gloves and other clothing as required to
minimize contact.
Respiratory protection : Avoid prolonged or repeated breathing of vapors or mists.
Use a NIOSH-approved respirator as required to prevent
overexposure.
In accord with 29 CFR 1910.134,
Use either a full-face, atmosphere-supplying respirator or
air-purifying respirator for organic vapors.
Avoid breathing vapors which may be produced under some
conditions such as heating or applications of uncured material in
large surface areas (e.g., flooring and painting).
Avoid breathing aerosols and mists which may be formed by
various methods of application.
