2. HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
WARNING! May cause allergic skin response in certain individuals. May cause moderate irritation to the skin. Clear to light yellow liquid with
mild odor.
ACUTE INHALATION:........................................................................ Not likely to cause acute effects unless heated to high temperatures. If
product is heated, vapors generated can cause headache, nausea, dizziness and possible respiratory irritation if inhaled in high concentrations.
CHRONIC INHALATION: ................................................................... Not likely to cause chronic effects. Repeated exposure to high vapor
concentrations may cause irritation of pre-existing lung allergies and increase the chance of developing allergy symptoms to this product.
ACUTE SKIN CONTACT: ................................................................... May cause allergic skin response in certain individuals. May cause
moderate irritation to the skin such as redness and itching.
CHRONIC SKIN CONTACT:............................................................... May cause sensitization in susceptible individuals. May cause moderate
irritation to the skin.
SYMPTOMS OF OVEREXPOSURE: .................................................. Possible sensitization and subsequent allergic reactions usually seen as
redness and rashes. Repeated exposure is not likely to cause other adverse health effects.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE:................ Pre-existing skin and respiratory disorders may be aggravated by exposure
to this product. Pre-existing lung and skin allergies may increase the chance of developing allergic symptoms to this product.
FIRST AID FOR EYES........................................................................ Flush immediately with water for at least 15 minutes. Consult a physician.
FIRST AID FOR SKIN......................................................................... Remove contaminated clothing. Wipe excess from skin. Remove with
waterless skin cleaner and then wash with soap and water. Consult a physician if effects occur.
FIRST AID FOR INGESTION.............................................................. No adverse health effects expected from amounts ingested under normal
conditions of use. Seek medical attention if a significant amount is ingested.
SPECIAL FIRE FIGHTING PROCEDURES: ....................................... Wear a self-contained breathing apparatus and complete full-body personal
protective equipment. Closed containers may rupture (due to buildup of pressure) when exposed to extreme heat.
FIRE AND EXPLOSION HAZARDS: .................................................. During a fire, smoke may contain the original materials in addition to
combustion products of varying composition which may be toxic and/or irritating. Combustion products may include, but are not limited to:
phenolics, carbon monoxide, carbon dioxide.
SPILL OR LEAK PROCEDURES: ...................................................... Stop leak without additional risk. Dike and absorb with inert material (e.g.,
sand) and collect in a suitable, closed container. Warm, soapy water or non-flammable, safe solvent may be used to clean residual.
STORAGE:......................................................................................... Store in cool, dry place. Store in tightly sealed containers to prevent
moisture absorption and loss of volatiles. Excessive heat over long periods of time will degrade the resin.
HANDLING PRECAUTIONS: ............................................................. Avoid prolonged or repeated skin contact. Wash thoroughly after handling.
Launder contaminated clothing before reuse. Avoid inhalation of vapors from heated product. Precautionary steps should be taken when curing
product in large quantities. When mixed with epoxy curing agents this product causes an exothermic, 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.
EYE PROTECTION GUIDELINES: ..................................................... Safety glasses with side shields or chemical splash goggles.
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:................................... Good room ventilation is usually adequate for most operations. Wear a
NIOSH/MSHA approved respirator with an organic vapor cartridge whenever exposure to vapor in concentrations above applicable limits is likely.
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 (epichlorohydrin, benzyl alcohol) were either so low that they were not detected at all or they were significantly below
OSHA’s permissible exposure levels.
ADDITIONAL PROTECTIVE MEASURES: ......................................... Practice good caution and personal cleanliness to avoid skin and eye
contact. Avoid skin contact when removing gloves and other protective equipment. Wash thoroughly after handling. Generally speaking, working
cleanly and following basic precautionary measures will greatly minimize the potential for harmful exposure to this product under normal use
conditions.
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.
HAZARDOUS POLYMERIZATION:.................................................... Will not occur by itself, but a mass of more than one pound of product plus
an aliphatic amine will cause irreversible polymerization with significant heat buildup.
INCOMPATIBILITIES: ........................................................................ Strong acids, bases, amines and mercaptans can cause polymerization.
DECOMPOSITION PRODUCTS: ........................................................ Carbon monoxide, carbon dioxide and phenolics may be produced during
uncontrolled exothermic reactions or when otherwise heated to decomposition.
No specific oral, inhalation or dermal toxicology data is known for this product. Specific toxicology information for a bisphenol-A based
epoxy resin present in this product is indicated below:
TERATOLOGY: ................................................. ………………Diglycidyl ether bisphenol-A (DGEBPA) did not cause birth defects or other adverse
effects on the fetus when pregnant rabbits were exposed by skin contact, the most likely route of exposure, or when pregnant rats or rabbits were
exposed orally.
REPRODUCTIVE EFFECTS:............................. ……………….DGEBPA, in animal studies, has been shown not to interfere with reproduction.
MUTAGENICITY: ............................................... ………………..DGEBPA in animal mutagenicity studies were negative. In vitro mutagenicity
tests were negative in some cases and positive in others.
CARCINOGENICITY:
NTP ............................................................................................ Product not listed.
IARC........................................................................................... Product not listed.
OSHA ......................................................................................... Product not listed.
No ingredient of this product present at levels greater than or equal to 0.1% is identified as a carcinogen or potential carcinogen by OSHA,
NTP or IARC.
Ethylbenzene, present in this product < 0.1%, is not identified by OSHA or NTP as a carcinogen, but is identified by NTP as a Group 2B
substance possibly carcinogenic to humans.
Many studies have been conducted to assess the potential carcinogenicity of diglycidyl ether of bisphenol-A. Although some weak evidence
of carcinogenicity has been reported in animals, when all of the data are considered, the weight of evidence does not show that DGEBPA is
carcinogenic. Indeed, the most recent review of the available data by the International Agency for Research on Cancer (IARC) has
concluded that DGEBPA is not classified as a carcinogen.
Epichlorohydrin, an impurity in this product (<5 ppm) has been reported to produce cancer in laboratory animals and to produce mutagenic
changes in bacteria and cultured human cells. It has been established by the International Agency for Research on Cancer (IARC) as a
probable human carcinogen (Group 2A) based on the following conclusions: human evidence – inadequate; animal evidence – sufficient. It
has been classified as an anticipated human carcinogen by the National Toxicology Program (NTP). Note: It is unlikely that normal use of
this product would result in measurable exposure concentrations to this substance.
Prevent entry into sewers and natural waters. May cause localized fish kill.
Ecotoxicology:
Material is moderately toxic to aquatic organisms on an acute basis. LC50/EC50 between 1 and 10 mg/L in most sensitive
species.
WASTE DISPOSAL METHOD:........................................................... Evaluation of this product using RCRA criteria shows that it is not a
hazardous waste, either by listing or characteristics, in its purchased form. It is the responsibility of the user to determine proper disposal
methods.
Incinerate, recycle (fuel blending) or reclaim may be preferred methods when conducted in accordance with federal, state and local regulations.
