FIRE AND EXPLOSION HAZARDS
High temperatures, inhibitor depletion, accidental impurities, or exposure to
radiation or oxidizers may cause spontaneous polymerizing reaction generating
heat/pressure. Closed containers may rupture or explode during runaway
polymerization.

EXTINGUISHING MEDIA
Dry chemical
CO2
Water spray
Foam
Water fog

SPECIAL FIREFIGHTING PROCEDURES
Do not enter fire area without proper protection. See Section 4 -
decomposition products possible. Fight fire from safe distance/protected
location. Heat/impurities may increase temperature/build pressure/rupture
closed containers, spreading fire, increasing risk of burns/injuries. Water
may be ineffective in firefighting due to low solubility. Use water
spray/fog for cooling. Pressure relief system may plug with solids,

increasing risk of overpressure. Notify authorities if liquid enters
sewer/public waters.

07. HEALTH HAZARDS
ROUTES OF EXPOSURE

INHALATION
No significant signs or symptoms indicative of any adverse health hazard are
expected to occur at standard conditions due to the low volatility of this
material. However, aerosols, or vapors which may be generated at elevated
processing temperatures, may cause respiratory tract irritation. Symptoms of
irritation may include coughing, mucous production and shortness of breath.

EYE CONTACT -- PRIMARY ROUTE
May cause minor eye irritation. Symptoms may include excessive tearing,
blinking and redness.

SKIN ABSORPTION
No appropriate human or animal health effects data are known to exist.

SKIN IRRITATION -- PRIMARY ROUTE
May cause minor skin irritation.
Symptoms of irritation may include a slight localized redness or rash and
swelling of the affected area. Symptoms of irritation may be delayed.
Although no appropriate human or animal health effects data is known to
exist, this material may cause an allergic skin reaction (sensitization) in
susceptible individuals upon repeated exposure.

INGESTION
This material may be a slight health hazard if ingested in large quantities.

MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE
No additional medical information found.

08. PROTECTIVE EQUIPMENT / CONTROL MEASURES
RESPIRATORY PROTECTION
If this material is handled at elevated temperature or under mist forming
conditions, NIOSH/MSHA approved respiratory protection equipment should be
used.

EYE PROTECTION
Eye protection such as chemical splash goggles and/or face shield must be
worn when possibility exists for eye contact due to splashing or spraying
liquid, airborne particles, or vapor. Contact lenses should not be worn.

SKIN PROTECTION
Depending on the conditions of use, protective gloves, apron, boots, head
and face protection should be worn. This equipment should be cleaned
thoroughly after each use.

ENGINEERING CONTROLS
If handling results in aerosol or vapor generation, local exhaust ventilation
is recommended.

OTHER HYGIENIC PRACTICES
Emergency eye wash fountains and safety showers should be available in the
immediate vicinity of any potential exposure.

OTHER WORK PRACTICES
Use good personal hygiene practices. Wash hands before eating, drinking,
smoking, or using toilet facilities. Promptly remove soiled clothing/wash
thoroughly before reuse. Shower after work using plenty of soap and water.

09. EMERGENCY AND FIRST AI INHALATION
If overcome by exposure, remove victim to fresh air immediately. Give oxygen
or artificial respiration as needed. Obtain emergency medical attention.
Prompt action is essential.

EYE CONTACT
In case of eye contact, immediately rinse with clean water for 20-30 minutes.
Retract eyelids often. Obtain emergency medical attention if pain, blinking,
tears or redness persist.

SKIN CONTACT
Remove contaminated clothing as needed. Wash skin thoroughly with mild
soap/water. Flush with lukewarm water for 15 minutes. If sticky, use waterless
cleaner first.

INGESTION
If large quantity swallowed, give lukewarm water (pint) if victim completely
conscious/alert. Do not induce vomiting/risk of damage to lungs exceeds
poisoning risk. Obtain emergency medical attention.

EMERGENCY MEDICAL TREATMENT PROCEDURES
Treat symptomatically.

10. SPILL AND DISPOSAL
PRECAUTIONS IF MATERIAL IS SPILLED OR RELEASE Spilled or released material may polymerize and release heat/gases.
Extinguish all ignition sources and ventilate area. Wear protective
equipment during clean-up. Dike and recover large spill. Soak up small
spill with inert solids (such as vermiculite, clay) and sweep/shovel into
vented disposal container. Wash spill area with a strong detergent and water
solution; rinse with water but minimize water use during clean-up. For
spills on water, contain, minimize dispersion and collect. Dispose/report
per regulatory requirements.

WASTE DISPOSAL METHODS


Date Printed: 01-17-2005  Sartomer Company

Product: SR355 Revised Date: 01-17-2005
MSDS ID: D-006183 Replaces Date: 01-06-2004

Non-contaminated, properly inhibited product is not a RCRA hazardous waste.
However, contaminated product/soil/water may be RCRA/OSHA hazardous waste due
to potential for internal heat generation (see 40 CFR 261 and 29 CFR 1910).
It is the responsibility of the generator to determine at the time of
disposal whether the product meets the criteria of a hazardous waste. Comply
with all applicable federal, state and local regulations. Use registered
transporters. Disposal options include landfilling solids at permitted
sites; fuel blending or incinerating liquids. Assure emissions comply with
applicable regulations. Dilute aqueous waste may biodegrade; avoid
overloading/poisoning plant biomass. Assure effluent complies with
applicable regulations.

11. ADDITIONAL PRECAUTIONS
HANDLING AND STORAGE PROCEDURES
Wear appropriate protective equipment when handling this material (See Section
8 of MSDS). Most acrylic monomers have low viscosities; hence, pouring,
material transfer and processing of these materials do not necessitate
heating. Viscous monomers may require heating to facilitate handling. To
facilitate product transfer from original container, product may be heated to
60C/140F for not more than 24 hours. Do NOT use localized heat sources such
as band heaters to heat/melt product. Do NOT use steam. Hot boxes or hot
rooms are recommended for heating/melting material. The hot box or hot room
should be set at a maximum temperature of 60C/140F. Do not overheat--this may
compromise product quality and/or result in an uncontrolled hazardous
polymerization. If product freezes, heat as indicated above and mix gently to
redistribute the inhibitor. Product should be consumed in its entirety after
heating/melting--avoid multiple "re-heats" which may affect product quality or
result in product degradation. Product is packaged with inhibitor(s). Unless
inhibited, product can polymerize, raising temperature and pressure possibly
rupturing container. Check inhibitor content periodically, adding to bulk
material if needed. In addition, the product's inhibitor(s) require the
presence of dissolved oxygen. Maintain, at a minimum, the original headspace
in the product container and do not blanket or mix with oxygen-free gas as it
renders inhibitor ineffective. Ensure air space (oxygen) is present during
product heating/melting.

Store product indoors at temperatures greater than product's freezing point
(or greater than 0C/32F if no freezing point available) and below 38C/100F.
Avoid prolonged (longer than shelf-life) storage temperatures above 38C/100F.
Store in tightly closed containers in a properly vented storage area away
from: heat, sparks, open flame, strong oxidizers, radiation, and other
initiators. Prevent contamination by foreign materials. Prevent moisture
contact. Use only non-sparking tools and limit storage time. Unless
specified elsewhere, shelf-life is 6 months from receipt.

DECONTAMINATION PROCEDURES
Follow standard plant procedures or supervisor's instructions for
decontamination operations.
