SECTION 3 HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
Appearance & Odor: Clear, colorless liquid with ammonia odor.
Health Hazards: Corrosive to skin. Corrosive to eye. May be moderately toxic if swallowed. May cause allergic
skin reaction. May be toxic and harmful if absorbed through the skin.
Physical Hazards: CORROSIVE.
Health Effects
Inhalation:
Vapors and mists may be corrosive to the respiratory tract. Repeated exposure may result in lung damage.
Eye Contact:
Corrosive (causing chemical burns) and may result in permanent eye damage or blindness. Vapors may be
irritating to the eye.
Skin Contact:
Corrosive (causing chemical burns) which may result in permanent skin damage. Repeated skin contact may
result in an allergic skin reaction causing itching, burning, redness and swelling. May be toxic and is harmful if
absorbed through the skin.
Ingestion:
Not expected to be a relevant route of exposure, however, corrosive to the mouth, throat and digestive system
and may cause chemical burns which could result in permanent damage to the areas contacted. May be harmful
if swallowed.
Signs and Symptoms:
Lung damage (scarring, bronchitis, emphysema) may be indicated by shortness of breath, especially on exertion
and may be accompanied by chronic cough.
Aggravated Medical Conditions:
Pre-existing eye, skin and respiratory disorders may be aggravated by exposure to this product.
SECTION 4 FIRST AID MEASURES
EPIKURE(TM) 3202 Curing Agent MSDS # 5097 Page of
Inhalation:
Move victim to fresh air. If the victim has difficulty breathing or tightness of the chest, is dizzy, vomiting or
unresponsive, give 100% oxygen with rescue breathing or CPR as required and transport to the nearest medical
facility.
Eye:
Immediately flush eyes with large amounts of water for at least 15 minutes, by the clock, while holding eyelids
open. Transport to nearest medical facility for additional treatment.
Skin:
Immediately remove contaminated clothing. Flush with large amounts of water for at least 15 minutes, by the
clock, or longer depending on the concentration amount and duration of exposure. Transport to nearest medical
facility for additional treatment.
Ingestion:
DO NOT induce vomiting. Have victim rinse mouth out with water, then drink sips of water to remove taste from
mouth. DO NOT GIVE LIQUIDS TO A DROWSY, CONVULSING OR UNCONSCIOUS PERSON. If vomiting
occurs spontaneously, keep head below hips to prevent aspiration. Transport to nearest medical facility for
additional treatment.
SECTION 5 FIRE FIGHTING MEASURES
212潞F / 100潞C
Flash Point:
Extinguishing Media:
Use water fog, 'alcohol foam', dry chemical or carbon dioxide (CO2) to extinguish flames. Water or fog may
cause frothing which can be violent, especially if sprayed into containers of hot or burning liquid.
Fire Fighting Instructions:
Material will not burn unless preheated. Clear fire area of all non-emergency personnel. Do not enter confined
fire space without full bunker gear (helmet with face shield, bunker coats, gloves and rubber boots), including a
positive pressure, NIOSH approved, self-contained breathing apparatus. Cool surrounding equipment, fire-
exposed containers and structures with water. Container areas exposed to direct flame contact should be cooled
with large quantities of water (500 gallons water per minute flame impingement exposure) to prevent weakening
of container structure.
Unusual Fire Hazards:
Delayed lung damage (pulmonary edema) can be experienced after exposure to combustion products, sometimes
hours after the exposure. Nitrogen oxides and other potentially hazardous nitrogen-containing compounds may
be released upon combustion.
SECTION 6 ACCIDENTAL RELEASE MEASURES
CORROSIVE. May burn although not readily ignitable.
TETA is resistant to biodegradation in biological waste water treatment plants. It could be toxic to the biomass in
a treatment plant and could be toxic to fish.
Protective Measures:
Prevent all bodily contact with spilled material.
Wear appropriate personal protective equipment (refer to Section 8) when responding to spills.
Spill Management:
Use cautious judgment when cleaning up large spills. Shut off source of leak if safe to do so. Dike and contain
EPI-CURE(TM) 3202 Curing Agent MSDS # 5097 Page of
spill. Remove with vacuum trucks or pump to storage/salvage vessels. Soak up residue with an absorbent such
as clay, sand or other suitable material and dispose of properly. Flush area with water to remove trace residue.
Contain run-off from residue flush and dispose of properly. Place in container for proper disposal. Prevent entry
into waterways, sewer, basements or confined areas. For small spills: Soak up residue with an absorbent such
as clay, sand or other suitable material. Place in non-leaking container and seal tightly for proper disposal.
Disposal:
Proper disposal should be evaluated based on regulatory status of this material (refer to Section 13), potential
contamination from subsequent use and spillage, and regulations governing disposal in the local area.
Reporting:
Notify authorities if any exposures to the general public or environment occurs or is likely to occur.
SECTION 7 HANDLING AND STORAGE
Do not taste or swallow. Avoid contact with eyes, skin and clothing. Wash thoroughly after handling.
Handling:
Heating this curing agent in the presence of air may cause thermal and oxidative decomposition. With some
epoxy resins, it 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.
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. Do not pressurize drum containers to empty.
Storage:
Store in a cool, dry place with adequate ventilation. Keep away from open flames and high temperatures. Keep
containers closed when not in use.
Avoid contact with hot liquid to prevent thermal burns.
Do not breathe fumes. 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.
Containers, even those that have been emptied, can contain hazardous residues.
SECTION 8 EXPOSURE CONTROLS/PERSONAL PROTECTION
Exposure Controls
The level of protection and types of controls necessary will vary depending upon potential exposure conditions.
Appropriate measures include:
Adequate ventilation to control airborne concentrations. Eye washes and showers for emergency use.
Personal Protective Equipment
Personal protective equipment (PPE) selections vary based on potential exposure conditions such as handling
practices, concentration and ventilation. Information on the selection of eye, skin and respiratory protection for
use with this material is provided below.
Eye Protection:
Chemical goggles
Skin Protection:
Use protective clothing which is chemical resistant to this material. Selection of protective clothing depends on
EPIKURE(TM) 3202 Curing Agent MSDS # 5097 Page of
potential exposure conditions and may include gloves, boots, suits and other items. The selection(s) should take
into account such factors as job task, type of exposure and durability requirements.
Respiratory Protection:
If engineering controls do not maintain airborne concentrations to a level which is adequate to protect worker
health, an approved respirator must be worn. Respirator selection, use and maintenance should be in
accordance with the requirements of the OSHA Respiratory Protection Standard, 29 CFR 1910.134.
Types of respirator(s) to be considered in the selection process include:
Air-Purifying Respirator for Organic Vapors, Full-Face Supplied-Air Respirator
