3. HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
HMIS Hazard Rating: Health - 3 Flammability - 1 Physical Hazards - 0
DANGER! Corrosive. Severe eye irritant. Severe skin irritant. Severe respiratory irritant. May cause skin sensitization. Harmful if
swallowed. Harmful if absorbed through the skin. Straw-yellow colored liquid, 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:............................................................... Moderately 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. Large
dose skin contact may result in material being absorbed in harmful amounts.
EYE CONTACT: ............................................................................. Causes severe irritation, pain and possible permanent injury. Vapor
absorption into the eye can cause blurred vision and injury.
INGESTION: ................................................................................... Moderately toxic. May cause bleeding of the gastrointestinal tract.
May cause burning of the mouth and throat. Aspiration hazard.
SYMPTOMS OF OVEREXPOSURE: ............................................. Development of allergic reaction or sensitization. Skin irritation and
redness. Respiratory irritation or tightness of chest. Conjunctivitis or corneal damage. Internal organ compalications.

MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE:
Chronic respiratory disease (e.g., bronchitis, asthma). Skin conditions and allergies. Eye disorders.
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 (PMCC)
EXTINGUISHING MEDIA: .............................................................. Water spray, dry chemical, alcohol foam and carbon dioxide (CO2).
FIRE AND EXPLOSION HAZARDS:.............................................. Burning can 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 GUIDELINES: ................................................ 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 GUIDELINES:
General mechanical or local exhaust ventilation. In the absence of adequate ventilation, use a NIOSH approved air purifying respirator
with an organic vapor cartridge.
Note: West System, Inc. has conducted an air sampling study using this product or similarly formulated products. The results indicate
that the components sampled for (phenol, formaldehyde and amines) were either so low that they were not detected at all or they were
well below OSHA's permissible exposure levels.
ADDITIONAL PROTECTIVE MEASURES:.................................... Use where there is immediate access to safety shower and emergency
eye wash. Provide proper wash/cleanup facilities for proper hygiene. Contact lens should not be worn when working with this material.
Generally speaking, working cleanly and following basic precautionary measures will greatly minimize the potential for harmful exposure
to this product under normal use conditions.
