  system depression and pulmonary edema. SKIN: Harmful if absorbed through
  skin.  Contact causes skin irritation.  Prolonged or repeated skin contact
  can result in defatting and drying of the skin. EYES: Harmful to eyes.
  Direct contact with this material causes eye irritation.  Symptoms may
  include stinging, tearing, redness and swelling. INGESTION:  Harmful if
  swallowed.  Single dose oral toxicity is low. Swallowing small amounts
  during normal handling is not likely to cause harmful effects; swallowing
  large amounts may be harmful.  Effects from exposure through ingestion may
 include gastrointestinal disturbances, pain and discomfort. Effects of
  exposure by ingestion may also include those indicated by the inhalation
  route.  Styrene is harmful or fatal if liquid is aspirated into the lungs.
Chronic Exposure:
  Overexposure to this material (or its components) has been suggested as a
  cause of the following effects in humans and may aggravate pre-existing
  disorders of these organs; central nervous system effects, effects on
  hearing and respiratory tract damage.
  This material contains styrene which is listed by the International Agency
  for Research (IARC) on Cancer as a group 2B cancer causing agent (possibly
  carcinogenic to humans).
Eye Contact:
  Immediately flush eyes with large quantities of clean water for at least
  15 minutes. Get immediate medical attention.
Skin Contact:
 Wash skin with soap and water. Remove contaminated clothing. Get medical
  attention if irritation develops or persists. Wash contaminated clothing
 before reuse.
  DO NOT INDUCE VOMITING. ASPIRATION HAZARD:  this material may enter the
  lungs during vomiting.   Immediately give the victim one or two glasses of
  water or milk to drink. Never give anything by mouth to an unconscious
  Remove victim to fresh air.  Keep warm and quiet. If not breathing, give

Effective Date: 01/12/2016                                                 Page 3
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.
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.
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, 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

Effective Date: 01/12/2016                                                Page 4
  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.
Signal Word:
  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.
Exposure Guidelines:
  The Occupational Safety and Health Administration (OSHA), has established
  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,

Effective Date: 01/12/2016                                                 Page 5
 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
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 necessary 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.

  Stable at normal temperatures and storage conditions.  See Section 7 for
  additional storage information.
  Avoid contact with strong acids, oxidizing agents (peroxides), metal salts
  and polymerization catalysts.
Hazardous Decomposition Products:
  Thermal decomposition may produce various hydrocarbons and irritating,
  acrid vapors.
Hazardous Polymerization:
  Product will undergo hazardous polymerization at temperatures above 150 F
  (65 C).  Hazardous polymerization will occur if contaminated with
  peroxides, metal salts and polymerization catalysts.
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.
  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.

  The International Agency for Research on Cancer (IARC) has classified
  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.
  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.
  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
  Aberration assay.
 Styrene is toxic to aquatic organisms and should not be released to sewage,
  drainage systems and all bodies of water at concentrations exceeding

Effective Date: 01/12/2016                                                 Page 8
  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).
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.
