Hazardous thermal decomposition products
Specific hazards arising from the chemical
Decomposition products may include the following materials: carbon dioxide, carbon monoxide, sulfur oxides halogenated compounds,
metal oxide/oxides
Flammable liquid and vapor. In a fire or if heated, a pressure increase will occur and the container may burst, with the risk of a
subsequent explosion. The vapor/gas is heavier than air and will spread along the ground. Vapors may accumulate in low or confined
areas or travel a considerable distance to a source of ignition and flash back. Runoff to sewer may create fire or explosion hazard. This
material is harmful to aquatic life with long lasting effects. Fire water contaminated with this material must be contained and prevented
from being discharged to any waterway, sewer or drain.
Fire-fighters should wear appropriate protective equipment and self-contained breathing apparatus (SCBA) with a full face-piece operated
in positive pressure mode.

5. FIRE-FIGHTING MEASURES
Suitable Extinguishing Media
Carbon dioxide (CO2), Foam, Dry chemical, Water spray
Unsuitable Extinguishing Media
Do not use a solid water stream as it may scatter and spread fire. Specific hazards arising from the chemical
Hazardous combustion products Combustion may produce carbon monoxide, carbon dioxide and irritating or toxic vapors
and gases
Combustion/Explosion Hazards Flammable. Vapors may form explosive mixture with air. Flash back possible over
considerable distance. 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. 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.
__________________________________________________________________________________________
Protective Equipment and Precautions for Firefighters:
Wear self-contained breathing apparatus (SCBA) and full fire-fighting protective clothing. Thoroughly decontaminate all protective
equipment after use. Evacuate all persons from the fire area to a safe 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. 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 cool
fire-exposed containers.

Unsuitable Extinguishing Media
Do not use a solid water stream as it may scatter and spread fire.
Specific hazards arising from the chemical
Hazardous combustion productsCombustion may produce carbon monoxide, carbon dioxide and irritating or toxic vapors
and gases
Combustion/explosion hazards Flammable. Vapors may form explosive mixtures with air. Flash back possible over
considerable distance. 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. 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.

_____________________________________________________________________________________________
5654 ; POLYLITE 32737-00 Revision Date 04/Sep/2018
equipment after use. Evacuate all persons from the fire area to a safe 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. 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 cool
fire-exposed containers.
6. ACCIDENTAL RELEASE MEASURES
Personal precautions, protective equipment and emergency procedures
Personal Precautions Remove all sources of ignition. Evacuate personnel to safe areas. Use personal protective
equipment as required. Ensure adequate ventilation. Keep people away from and upwind of
spill/leak. Beware of vapors accumulating to form explosive concentrations. Vapors can
accumulate in low areas.
Environmental precautions
Environmental precautions Prevent further leakage or spillage if safe to do so. Do not allow material to contaminate
ground water system. Prevent product from entering drains. Soak up with inert absorbent
material and dispose of as hazardous waste. Beware of vapors accumulating to form
explosive concentrations. Vapors can accumulate in low areas.
Methods and material for containment and cleaning up
Methods for Containment Prevent spilled material from 1) contaminating soil, 2) entering sanitary sewers, storm
sewers, and drainage systems, and 3) entering bodies of water or ditches that lead to
waterways. Prevent spreading over a wide area (e.g. by containment or oil barriers).
Methods for Clean-up Soak up with inert absorbent material. Remove from surface water (e.g. by skimming or
siphoning). Dispose of contaminated material as waste according to item 13.
7. HANDLING AND STORAGE
Precautions for safe handling
Handling Do not breathe vapor or mist. Avoid contact with skin, eyes or clothing. Wash hands before
breaks and immediately after handling the product. Take off contaminated clothing and
wash before reuse. Ensure adequate ventilation. Ground and bond containers when
transferring material. 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.
Conditions for safe storage, including any incompatibilities
Storage Keep away from heat and sources of ignition. No smoking. Protect from direct sunlight.
Keep containers tightly closed in a cool, well-ventilated place. To ensure maximum stability
and maintain optimum resin properties, resins should be stored in closed containers at
temperatures below 77 F (25 C).

Appropriate engineering controls
Engineering Controls Use general ventilation to maintain airborne concentrations to levels that are below
regulatory and recommended occupational exposure limits. Local ventilation may be
required during certain operations. Use explosion-proof electrical equipment.
Individual protection measures, such as personal protective equipment
Eye/face Protection Safety glasses with side-shields. If splashes are likely to occur:. Tight sealing safety
goggles. Ensure that eyewash stations and safety showers are close to the workstation
location.
Skin Protection Wear protective nitrile rubber or Viton gloves. Gloves made of nitrile rubber or polyvinyl
chloride (PVC) may be used for splash protection and brief or intermittent contact with
styrenated polyester resin. Please observe the instructions regarding permeability and
breakthrough time which are provided by the supplier of the gloves. Also take into
consideration the specific local conditions under which the product is used, such as the
danger of cuts, abrasion. Impervious clothing. Rubber or plastic boots.
Respiratory Protection None required if hazards have been assessed and airborne concentrations are maintained
below the exposure limits listed in Section 8. Wear an approved air-purifying respirator with
organic vapor cartridges and particulate filters where airborne concentrations may exceed
exposure limits in Section 8 and/or there is exposure to dust or mists due to sanding,
grinding, cutting, or spraying. Use an approved positive-pressure air-supplied respirator
with emergency escape provisions if there is any potential for an uncontrolled release,
airborne concentrations are not known, or any other circumstances where air-purifying
respirators may not provide adequate protection.
General Hygiene Considerations Handle in accordance with good industrial hygiene and safety practice.

5. FIRE-FIGHTING MEASURES
Suitable Extinguishing Media
Carbon dioxide (CO2), Foam, Dry chemical, Water spray
Unsuitable Extinguishing Media
Do not use a solid water stream as it may scatter and spread fire.
Specific hazards arising from the chemical
Hazardous combustion productsCombustion may produce carbon monoxide, carbon dioxide and irritating or toxic vapors
and gases
Combustion/explosion hazards Flammable. Vapors may form explosive mixtures with air. Flash back possible over
considerable distance. 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. 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.

Protective Equipment and Precautions for Firefighters
Wear self-contained breathing apparatus (SCBA) and full fire-fighting protective clothing. Thoroughly decontaminate all protective
_____________________________________________________________________________________________
5654 ; POLYLITE 32737-00 Revision Date 04/Sep/2018
equipment after use. Evacuate all persons from the fire area to a safe 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. 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 cool
fire-exposed containers.
6. ACCIDENTAL RELEASE MEASURES
Personal precautions, protective equipment and emergency procedures
Personal Precautions Remove all sources of ignition. Evacuate personnel to safe areas. Use personal protective
equipment as required. Ensure adequate ventilation. Keep people away from and upwind of
spill/leak. Beware of vapors accumulating to form explosive concentrations. Vapors can
accumulate in low areas.
Environmental precautions
Environmental precautions Prevent further leakage or spillage if safe to do so. Do not allow material to contaminate
ground water system. Prevent product from entering drains. Soak up with inert absorbent
material and dispose of as hazardous waste. Beware of vapors accumulating to form
explosive concentrations. Vapors can accumulate in low areas.
Methods and material for containment and cleaning up
Methods for Containment Prevent spilled material from 1) contaminating soil, 2) entering sanitary sewers, storm
sewers, and drainage systems, and 3) entering bodies of water or ditches that lead to
waterways. Prevent spreading over a wide area (e.g. by containment or oil barriers).
Methods for Clean-up Soak up with inert absorbent material. Remove from surface water (e.g. by skimming or
siphoning). Dispose of contaminated material as waste according to item 13.
7. HANDLING AND STORAGE
Precautions for safe handling
Handling Do not breathe vapor or mist. Avoid contact with skin, eyes or clothing. Wash hands before
breaks and immediately after handling the product. Take off contaminated clothing and
wash before reuse. Ensure adequate ventilation. Ground and bond containers when
transferring material. 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.
Conditions for safe storage, including any incompatibilities
Storage Keep away from heat and sources of ignition. No smoking. Protect from direct sunlight.
Keep containers tightly closed in a cool, well-ventilated place. To ensure maximum stability
and maintain optimum resin properties, resins should be stored in closed containers at
temperatures below 77 F (25 C).

Engineering Controls Use general ventilation to maintain airborne concentrations to levels that are below
regulatory and recommended occupational exposure limits. Local ventilation may be
required during certain operations. Use explosion-proof electrical equipment.
Individual protection measures, such as personal protective equipment
Eye/face Protection Safety glasses with side-shields. If splashes are likely to occur:. Tight sealing safety
goggles. Ensure that eyewash stations and safety showers are close to the workstation
location.
Skin Protection Wear protective nitrile rubber or Viton gloves. Gloves made of nitrile rubber or polyvinyl
chloride (PVC) may be used for splash protection and brief or intermittent contact with
styrenated polyester resin. Please observe the instructions regarding permeability and
breakthrough time which are provided by the supplier of the gloves. Also take into
consideration the specific local conditions under which the product is used, such as the
danger of cuts, abrasion. Impervious clothing. Rubber or plastic boots.
Respiratory Protection None required if hazards have been assessed and airborne concentrations are maintained
below the exposure limits listed in Section 8. Wear an approved air-purifying respirator with
organic vapor cartridges and particulate filters where airborne concentrations may exceed
exposure limits in Section 8 and/or there is exposure to dust or mists due to sanding,
grinding, cutting, or spraying. Use an approved positive-pressure air-supplied respirator
with emergency escape provisions if there is any potential for an uncontrolled release,
airborne concentrations are not known, or any other circumstances where air-purifying
respirators may not provide adequate protection.
General Hygiene Considerations Handle in accordance with good industrial hygiene and safety practice.

5. FIRE-FIGHTING MEASURES
Suitable Extinguishing Media
Carbon dioxide (CO2), Foam, Dry chemical, Water spray
Unsuitable Extinguishing Media
Do not use a solid water stream as it may scatter and spread fire.
Specific hazards arising from the chemical
Hazardous combustion productsCombustion may produce carbon monoxide, carbon dioxide and irritating or toxic vapors
and gases
Combustion/explosion hazards Flammable. Vapors may form explosive mixtures with air. Flash back possible over
considerable distance. 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. 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.

Protective Equipment and Precautions for Firefighters
Wear self-contained breathing apparatus (SCBA) and full fire-fighting protective clothing. Thoroughly decontaminate all protective
_____________________________________________________________________________________________
5654 ; POLYLITE 32737-00 Revision Date 04/Sep/2018
equipment after use. Evacuate all persons from the fire area to a safe 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. 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 cool
fire-exposed containers.
6. ACCIDENTAL RELEASE MEASURES
Personal precautions, protective equipment and emergency procedures
Personal Precautions Remove all sources of ignition. Evacuate personnel to safe areas. Use personal protective
equipment as required. Ensure adequate ventilation. Keep people away from and upwind of
spill/leak. Beware of vapors accumulating to form explosive concentrations. Vapors can
accumulate in low areas.
Environmental precautions
Environmental precautions Prevent further leakage or spillage if safe to do so. Do not allow material to contaminate
ground water system. Prevent product from entering drains. Soak up with inert absorbent
material and dispose of as hazardous waste. Beware of vapors accumulating to form
explosive concentrations. Vapors can accumulate in low areas.
Methods and material for containment and cleaning up
Methods for Containment Prevent spilled material from 1) contaminating soil, 2) entering sanitary sewers, storm
sewers, and drainage systems, and 3) entering bodies of water or ditches that lead to
waterways. Prevent spreading over a wide area (e.g. by containment or oil barriers).
Methods for Clean-up Soak up with inert absorbent material. Remove from surface water (e.g. by skimming or
siphoning). Dispose of contaminated material as waste according to item 13.
7. HANDLING AND STORAGE
Precautions for safe handling
Handling Do not breathe vapor or mist. Avoid contact with skin, eyes or clothing. Wash hands before
breaks and immediately after handling the product. Take off contaminated clothing and
wash before reuse. Ensure adequate ventilation. Ground and bond containers when
transferring material. 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.
Conditions for safe storage, including any incompatibilities
Storage Keep away from heat and sources of ignition. No smoking. Protect from direct sunlight.
Keep containers tightly closed in a cool, well-ventilated place. To ensure maximum stability
and maintain optimum resin properties, resins should be stored in closed containers at
temperatures below 77 F (25 C).

Appropriate engineering controls
Engineering Controls Use general ventilation to maintain airborne concentrations to levels that are below
regulatory and recommended occupational exposure limits. Local ventilation may be
required during certain operations. Use explosion-proof electrical equipment.
Individual protection measures, such as personal protective equipment
Eye/face Protection Safety glasses with side-shields. If splashes are likely to occur:. Tight sealing safety
goggles. Ensure that eyewash stations and safety showers are close to the workstation
location.
Skin Protection Wear protective nitrile rubber or Viton gloves. Gloves made of nitrile rubber or polyvinyl
chloride (PVC) may be used for splash protection and brief or intermittent contact with
styrenated polyester resin. Please observe the instructions regarding permeability and
breakthrough time which are provided by the supplier of the gloves. Also take into
consideration the specific local conditions under which the product is used, such as the
danger of cuts, abrasion. Impervious clothing. Rubber or plastic boots.
Respiratory Protection None required if hazards have been assessed and airborne concentrations are maintained
below the exposure limits listed in Section 8. Wear an approved air-purifying respirator with
organic vapor cartridges and particulate filters where airborne concentrations may exceed
exposure limits in Section 8 and/or there is exposure to dust or mists due to sanding,
grinding, cutting, or spraying. Use an approved positive-pressure air-supplied respirator
with emergency escape provisions if there is any potential for an uncontrolled release,
airborne concentrations are not known, or any other circumstances where air-purifying
respirators may not provide adequate protection.
General Hygiene Considerations Handle in accordance with good industrial hygiene and safety practice.
