3. HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
HMIS Hazard Rating: Health - 3 Flammability - 1 Reactivity - 0
DANGER! Corrosive. Severe eye irritant. Severe skin irritant. Severe respiratory irritant. May cause skin
sensitization. Harmful if swallowed. Harmful if in contact with skin. Yellow colored liquid with ammonia odor.
PRIMARY ROUTE(S) OF ENTRY:............................ Skin contact, eye contact, inhalation.
POTENTIAL HEALTH EFFECTS:
ACUTE INHALATION: .............................................. Exposure to high concentrations of vapor causes
irritation to the respiratory tract. Coughing and chest pain may result.
CHRONIC INHALATION:.......................................... Prolonged or repeated exposure to high concentrations
of vapors may cause lung tissue damage. Exposure to low vapor concentrations may cause a sore throat.
ACUTE SKIN CONTACT: ......................................... Corrosive. Prolonged contact may cause skin damage
with burns and blistering. Wide spread contact may result in material being absorbed in harmful amounts.

CHRONIC SKIN CONTACT:..................................... May cause persistent irritation or dermatitis. Repeated
contact may cause allergic reaction/sensitization and possible skin tissue destruction. Repeated absorption
may cause internal organ damage.
EYE CONTACT: ........................................................ Corrosive. Causes irritation and may cause chemical
burns resulting in permanent damage. Vapors may cause blurred vision when absorbed into eye tissue.
INGESTION: .............................................................. Corrosive. Causes burning of the mouth and throat.
May cause bleeding of the gastrointestinal tract and vomiting. Aspiration hazard.
SYMPTOMS OF OVEREXPOSURE: ........................ Persistent irritation or dermatitis. Skin sensitization or
allergic reaction. Irritation to the respiratory tract, headache, nausea. Redness and swelling of the eye. Liver
or kidney damage.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE:
Existing skin and respiratory conditions (allergies, dermatitis, asthma, bronchitis).
4. FIRST AID MEASURES:
FIRST AID FOR EYES: ............................................. Immediately flush with water for at least 15 minutes. Get
prompt medical attention.
FIRST AID FOR SKIN: .............................................. Remove contaminated clothing. Immediately wash skin
with soap and water. Do not apply greases or ointments. Get medical attention if severe exposure.
FIRST AID FOR INHALATION: ................................ If symptoms occur as noted in Section 3, remove to
fresh air. Get medical attention if symptoms persist or worsen.
FIRST AID FOR INGESTION:................................... Give conscious person at least 2 glasses of water. Do
not induce vomiting. If vomiting should occur spontaneously, keep airway clear. Get medical attention.
5. FIRE FIGHTING MEASURES:
FLASH POINT: .......................................................... > 200癋.
EXTINGUISHING MEDIA: ......................................... Water spray, dry chemical, alcohol foam and carbon
dioxide (CO2).
FIRE AND EXPLOSION HAZARDS: ........................ Burning will generate toxic fumes. When mixed with
sawdust, wood chips, or other cellulosic material, spontaneous combustion can occur under certain
conditions. If hardener is spilled into or mixed with sawdust, heat is generated as the air oxidizes the amine.
If the heat is not dissipated quickly enough, it can ignite the sawdust.
SPECIAL FIRE FIGHTING PROCEDURES: ............ Use full-body protective gear and a self-contained
breathing apparatus. If spill has ignited, use water spray to disperse vapors and protect personnel attempting
to stop leak. Use water to cool fire-exposed containers.
6. ACCIDENTAL RELEASE MEASURES:
SPILL OR LEAK PROCEDURES: Stop leak without additional risk. Wear proper personal protective
equipment. Dike and contain spill. Ventilate area. Large spill - dike and pump into appropriate container for
recovery. Small spill - dilute with water and recover or use inert, non-combustible absorbent material (e.g.,
sand) and shovel into suitable container. Do not use sawdust, wood chips or other cellulosic materials to
absorb the spill, as the possibility for spontaneous combustion exists. Wash spill residue with warm, soapy
water if necessary.

7. HANDLING AND STORAGE:
STORAGE TEMPERATURE (min./max.): ............... 40癋 (4癈) / 90癋 (32癈).
STORAGE: ................................................................ Minimum feasible handling temperatures should be
maintained. If stored above 100癋, nitrogen atmosphere is recommended. Keep containers tightly closed.
HANDLING PRECAUTIONS:.................................... Use only with adequate ventilation. Do not breath
vapors or mists from heated material. Avoid contact with skin and eyes. Wash thoroughly after handling.
When mixed with epoxy resin this product causes an exothermic reaction, which in large masses, can
produce enough heat to damage or ignite surrounding materials and emit fumes and vapors that vary widely
in composition and toxicity.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION:
EYE PROTECTION REQUIREMENTS: .................... Chemical splash goggles or full-face shield.
SKIN PROTECTION GUIDELINES:.......................... Wear liquid-proof, chemical resistant gloves (nitrile-butyl
rubber, neoprene, butyl rubber or natural rubber) and full body-covering clothing.
RESPIRATORY/VENTILATION REQUIREMENTS:
General mechanical or local exhaust ventilation. In the absence of adequate ventilation controls, use a
NIOSH approved air purifying respirator with an organic vapor cartridge.
ADDITIONAL PROTECTIVE MEASURES: .............. Use where there is immediate access to safety shower
and emergency eye wash. Provide proper wash/cleanup facilities for proper hygiene.
OCCUPATIONAL EXPOSURE LIMITS: ................... Not established for product as whole. Refer to OSHA's
Permissible Exposure Level (PEL) or the ACGIH Guidelines for information on specific ingredients.
9. PHYSICAL AND CHEMICAL PROPERTIES:
PHYSICAL FORM ..................................................... Liquid.
COLOR ...................................................................... Yellow.
ODOR......................................................................... Ammonia-like.
BOILING POINT ........................................................ > 480癋.

VISCOSITY ................................................................ 85 cP.
% VOLATILE BY WEIGHT........................................ EPA Method 24, as described in 40 CFR Part 60, was
used to determine the Volatile Matter Content of mixed epoxy resin and hardener. This method states that
two-component coating systems should be tested by determining weight loss after mixing the individual
components together at the proper ratio, dissolving them in an appropriate solvent, and subjecting them to a
temperature of 230癋. 105 Resin and 209 Hardener, mixed together at 3:1 by weight, has a density of 1148
g/L (9.58 lbs/gal). The combined VOC content for 105/209 is 88.2 g/L (0.74 lbs/gal).
