5. FIRE FIGHTING MEASURES

NFPA Hazard Classification
-------------------------------------
Health Hazard:
Fire Hazard: 2
Specific Hazard: 3
Reactivity: 1

Flash Point: 89 degrees F (32 degrees C)
Flash Point Method Used: SetaFlash Closed Cup
Flammable Limits in Air (Lower): > 1.1 % in air Styrene
Flammable Limits in Air (Upper): < 7 % in air Styrene
Autoignition: 914 degrees F (490 degrees C) Styrene

General Hazards:
FLAMMABLE LIQUID: This material's flash point is less than 100 degrees F
(38 degrees C). Use water in flooding quantities as a fog to extinguish
the fire. DO NOT USE a solid stream of water as that may spread the fire.
DO NOT extinguish a fire resulting from the flow of this flammable liquid
until the flow of liquid is effectively shut off. This precaution will
help prevent the accumulation of an explosive vapor-air mixture after the
initial fire is extinguished.


Fire Fighting Extinguishing Media:
Use carbon dioxide, foam, dry chemical or water fog to extinguish fire.

1-800-424-9300
--------------------------------------------------------------------------------
Effective Date: 05/30/13 Page 4
--------------------------------------------------------------------------------


Fire Fighting Equipment:
Wear self-contained breathing apparatus (SCBA) and full fire-fighting
protective clothing. Thoroughly decontaminate all protective equipment
after use.


Fire Fighting Instructions:
Evacuate all persons from the fire area to an explosion-protected location.
Move non-burning material, as feasible, to a safe location as soon as
possible. Fire fighters should be protected from potential explosion
hazard while extinguishing the blaze. Containers of this material may
build up pressure if exposed to heat (fire). Use water spray to cool fire-
exposed containers. DO NOT extinguish a fire resulting from the flow of
this flammable liquid until the flow of liquid is effectively shut off.
This precaution will help prevent the accumulation of an explosive vapor-
air mixture after the initial fire is extinguished. Use water spray to
disperse vapors if a spill or leak has not ignited. See Section 13 for
disposal considerations.


Fire and Explosion Hazards:
FLAMMABLE LIQUID. Vapors can form an explosive mixture with air. Vapor
can travel to a source of ignition (spark or flame) and flash back. This
material may polymerize (react) when its container is exposed to heat (as
during a fire). This polymerization increases pressure inside a closed
container and may result in the violent rupture of the container.


Hazardous Combustion Products:
Combustion may produce carbon monoxide, carbon dioxide and irritating or
toxic vapors and gases.


================================================================================

6. ACCIDENTAL RELEASE MEASURES

FOR SMALL SPILLS: Absorb spill with inert material (e.g., dry sand or
earth), then place in a chemical waste container. Use non-sparking (non-
metallic) tools to clean up spill. Remove all sources of ignition. NO
SMOKING.

FOR LARGE SPILLS: Eliminate all ignition sources (flares, flames including
pilot lights, electrical sparks). NO SMOKING. Persons not wearing
protective equipment (see Section 8) should be excluded from the area of
the spill until clean-up has been completed. Stop spill at source. Prevent
spilled material from contaminating soil or entering drains, sewers,


Effective Date: 05/30/13 Page 5
--------------------------------------------------------------------------------
streams or other bodies of water. Prevent spilled material from spreading.
Immediately notify authorities of any reportable spill as may be required
pursuant to regulations. See Section 15 for applicable CERCLA reportable
quantities. Pump or vacuum transfer spilled product to clean containers
for recovery. Absorb unrecoverable product. Transfer contaminated
absorbent, soil and other waste materials to waste containers for disposal.
See Section 13 for disposal considerations.


================================================================================

7. HANDLING AND STORAGE

W A R N I N G


Handling Information:
Avoid inhalation and contact with eyes, skin, and clothing. Wash hands
thoroughly after handling and before eating or drinking. Remove and wash
contaminated clothing before reuse. Use with adequate ventilation.
Ground and bond containers when transferring the material to prevent
static electricity sparks which could ignite the vapor. Use spark-proof
tools and explosion-proof equipment. Consult your supplier of promoters
and catalysts for additional instructions on proper mixing and usage.

Empty containers may retain product residue (liquid and/or vapor). Do not
pressurize, cut, weld, braze, solder, drill, grind, or expose these
containers to heat, flame, sparks, static electricity, or other sources of
ignition as the container may explode and may cause injury or death.
Empty drums should be completely drained and properly bunged. Empty drums
should be promptly returned to a drum reconditioner or properly disposed.
See Section 13 for disposal considerations.


Storage Information:
Keep away from ignition sources: flames, pilot lights, electrical sparks,
and sparking tools. NO SMOKING. Do not store in direct sunlight. Store
separate from oxidizing materials, peroxides, and metal salts. Keep
container closed when not in use. To ensure maximum stability and
maintain optimum resin properties, resins should be stored in closed
containers at temperatures below 75 degrees F (25 degrees C). Copper or
copper containing alloys should be avoided as containers.


================================================================================

8. EXPOSURE CONTROLS / PERSONAL PROTECTION

Exposure Guidelines:
The Occupational Safety and Health Administration (OSHA), has established


Effective Date: 05/30/13 Page 6
--------------------------------------------------------------------------------
for styrene, a Permissible Exposure Limit (PEL) of 100 ppm for an 8 hour
Time Weighted Average (TWA); 200 ppm for an acceptable ceiling
concentration; and a 600 ppm concentration within a duration of 5 minutes
in any 3 hours as an acceptable maximum peak above the acceptable ceiling
concentration for an 8 hour shift. While the federal workplace exposure
limit for styrene is 100 ppm, OSHA accepted the styrene industry's
proposal to voluntarily meet a PEL of 50 ppm on an 8 hour TWA and a Short
Term Exposure Limit (STEL) of 100 ppm, 15 minute exposure.

The American Conference of Governmental Industrial Hygenists (ACGIH) have
established, for styrene, Threshold Limit Values (TLV) of 20 ppm or 85
mg/m3 TWA and 40 ppm or 170 mg/m3 Short Term Exposure Limit (STEL), 15
minute exposure, with a skin notation which indicates absorption through
the skin which could add to the employees exposure.


Engineering Controls:
The use of general or local exhaust ventilation may be required to
maintain exposures below the regulatory or recommended occupational
exposure limits. See occupational exposure limits in Section 2 and under
Exposure Guidelines in Section 8. Use explosion-proof ventilation
equipment.


Eye Protection:
Wear 1) safety glasses with side shields and a faceshield or 2) goggles
and a faceshield. Facilities storing or utilizing this material should be
equipped with an eyewash station and safety shower.


Skin Protection:
Wear chemical resistant gloves such as polyvinyl alcohol or Viton (R) .
If splashing is likely, wear impervious clothing and boots to prevent
repeated or prolonged skin contact. Consult your supplier of personal
protective equipment for additional instructions on proper usage.


Respiratory Protection:
A NIOSH/MSHA approved air purifying respirator with organic vapor
cartridge or canister may be permissible under certain circumstances where
airborne concentrations are expected to exceed exposure limits. See
Section 2 and 8 for applicable occupational exposure limits. A respiratory
protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2
requirements must be followed whenever workplace conditions warrant a
respirator's use. Protection provided by air purifying respirators is
limited. Use a positive pressure air-supplied respirator if 1) there is
any potential for an uncontrolled release, 2) exposure levels are not
known, or 3) during other circumstances where air purifying respirators
may not provide adequate protection.

================================================================================

11. TOXICOLOGICAL INFORMATION


Effective Date: 05/30/13 Page 8
--------------------------------------------------------------------------------

Acute Eye Toxicity:
Studies indicate that exposures to concentrations of styrene above 200 ppm
cause irritation of the eyes. Styrene causes transient moderate eye
irritation without corneal involvement.


Acute Skin Toxicity:
Draize Skin Primary Irritation Score (range, 0-8) for a 4-hour exposure
(rabbits) to styrene is 6.6. Styrene: dermal LD50 (rabbit), 5 g/kg.
Styrene causes severe irritation at 72 hours.


Acute Inhalation Toxicity:
Styrene: inhalation LC50 (rat), 24 g/m3 /4 hrs. Studies indicate that
exposures to concentrations of styrene above 200 ppm cause irritation of
the upper respiratory tract. Acute exposure to high concentrations of
styrene may produce irritation of the mucous membranes of the upper
respiratory tract, nose, and mouth, followed by symptoms of narcosis,
muscular contraction, and death due to respiratory center paralysis.


Acute Oral Toxicity:
Styrene: oral LD50 (rat), 5 g / kg.


Subchronic:
Styrene: inhalation NOEL(rat) 200 ppm 6 hr / day 13 weeks, target organ
effects: auditory response; inhalation LOEL (rat) 800 ppm 6 hr / day 3 -
13 weeks, target organ effects: auditory response.

Styrene has been shown to cause probable hearing loss in rats exposed for
at least six hours per day for three to thirteen weeks to 800 ppm of
styrene in the air, as indicated by a rise in the auditory brainstem
response threshold and loss of hair cells of the inner ear. No effects
were observed in rats exposed to styrene at 200 ppm for 13 weeks. Based on
animal studies and human experience, no significant risk of hearing loss
is expected in occupationally exposed persons.

Overexposure to styrene has been suggested as a cause of the following
effects in laboratory animals and may aggravate pre-existing disorders of
the following organs in humans; mild, reversible kidney effects, effects
on hearing, respiratory tract damage, testis damage and liver damage.


Chronic/Carcinogenicity:
The International Agency for Research on Cancer (IARC) has classified


Effective Date: 05/30/13 Page 9
--------------------------------------------------------------------------------
styrene in Group 2B, possibly carcinogenic to humans. IARC concluded that
evidence of carcinogenicity from human health studies, was inadequate and
based the classification on animal and other relevant data. The animal
data included an increased incidence of cancer observed in a few studies
in which rats and mice were given styrene by inhalation or by ingestion
for their lifetimes. IARC considered the combined results of these cancer
studies to provide "limited evidence" of carcinogenicity. Other scientists
consider the results of these studies inadequate to assess human
carcinogenicity because these studies had either negative or statistically
inconclusive results or had serious problems such as poor study design or
very high mortality. Other relevant data included results from in-vivo and
in-vitro genotoxicity studies. IARC also relied on data on styrene oxide
including the results of two studies demonstrating stomach tumors in rats
that were fed styrene oxide for their lifetime. Several epidemiology
studies involving workers in the styrene, polystyrene or reinforced
plastics industries have been conducted. Together, these studies show no
increased cancer risk from occupational exposure to styrene.

Preliminary results of a recent inhalation study indicated that mice
exposed to styrene showed an increased incidence of lung tumors, however
no dose response relationship was observed. The relevance of these
findings is uncertain since data from other long-term animal studies and
from epidemiology studies of workers exposed to styrene do not provide a
basis to conclude that styrene is carcinogenic.

The American Conference of Governmental Industrial Hygienists (ACGIH) has
adopted the listing of Styrene as "A4-Not Classifiable as a Human
Carcinogen." There is inadequate data on which to classify the agent in
terms of its carcinogenicity in humans and/or animals.


Teratology:
Styrene did not cause birth defects in orally-dosed rats, mice, rabbits
and hamsters exposed by inhalation. Styrene given by inhalation for six
hours a day during organ development has been shown to be toxic to fetal
mice at 250 ppm and to fetal hamsters at 1000 ppm. Information from human
experience and the results of animal studies suggest no significant risk
of birth defects or reproductive toxicity of styrene to humans.


Mutagenicity:
Styrene has given mixed positive and negative results in a number of
mutagenicity tests. It was not mutagenic in the Ames test without
metabolic activation but gave negative and positive mutagenic results with
metabolic activation. It has also given negative mutagenic results in the
Chinese Hamster Ovary Test, and the Forward Gene Mutation Test and
positive results in the Sister Chromatid Exchange and the Chromosomal


Effective Date: 05/30/13 Page 10

Aberration assay.


================================================================================

12. ECOLOGICAL INFORMATION

Ecotoxicity:
Styrene is toxic to aquatic organisms and should not be released to sewage,
drainage systems and all bodies of water at concentrations exceeding
approved limits under applicable regulations and permits. Styrene: LC50
(Sheepshead minnow), 9.1 mg / l / 96 hr.


Environmental Fate:
Styrene released to soil is subject to biodegradation. The results of one
extensive biological screening study suggest that styrene will be rapidly
destroyed by biodegradation in most aerobic environments, but the rate may
be slow at low concentrations in aquifers and lake waters and in
environments at low pH (6).


================================================================================

13. DISPOSAL CONSIDERATIONS

Waste Disposal Method:
RCRA HAZARDOUS WASTE: This material and containers that are not empty, if
discarded, would be regulated as a hazardous waste under RCRA. Treatment
and/or disposal must be completed at a RCRA-permitted Treatment, Storage
and Disposal Facility (TSD). The storage and transportation of RCRA
hazardous wastes are also regulated by the USEPA.

EMPTY DRUMS: "Empty containers", as defined under 40 CFR 261.7 or other
applicable state or provincial regulations or transportation regulations,
are not classified as hazardous wastes.


RCRA Hazard Class:
D001 (IGNITABLE): When discarded in its purchased form, this material
would be regulated under 40 CFR 261.21 as EPA Hazardous Waste Number D001
based on the characteristic of ignitability.
