EMERGENCY RESPONSE INFORMATION
_________________________________________________________________
FIRST AID:
INHALATION: Move subject to fresh air. If breathing is
1
difficult, give oxygen. Give artificial
respiration if breathing has stopped. Call a
physician.
EYE CONTACT: IMMEDIATELY flush eyes with a large amount of
water for at least 15 minutes. Get prompt medical
attention.
SKIN CONTACT: Wash skin thoroughly with soap and water. Remove
and wash contaminated clothing thoroughly. See a
physician.
INGESTION: If swallowed, give 2 glasses of water to drink.
Never give anything by mouth to an unconscious
person. Consult a physician.
FIRE FIGHTING INFORMATION:
UNUSUAL HAZARDS: Heat can cause polymerization. Heated containers
can explode.
EXTINGUISHING AGENTS: Carbon dioxide - dry chemical - water spray.
PERSONAL PROTECTIVE EQUIPMENT:
Wear self-contained breathing apparatus (pressure-demand MSHA/
NIOSH approved or equivalent) and full protective gear.
SPECIAL PROCEDURES: EXPLOSION HAZARD. Fight advanced fires from
a protected location. Use water spray to
cool containers exposed to fire.
SPILL OR LEAK HANDLING INFORMATION:
PERSONAL PROTECTION:
Appropriate protective equipment must be worn when handling a
spill of this material. See the PERSONAL PROTECTION MEASURES
Section for recommendations. If exposed to material during
clean-up operations, see the FIRST AID PROCEDURES
PROCEDURES:
Keep spectators away. Contain spills immediately with inert
materials (e.g. sand, earth). Transfer liquids and solid diking
material to separate suitable containers for recovery or
disposal. Contaminated monomer may be unstable. Add inhibitor
to prevent polymerization. See WASTE DISPOSAL Section for
information regarding the disposal of contained spills.
NOTE: Spills on porous surfaces can contaminate groundwater.
2
CAUTION: Keep spills and cleaning runoff out of municipal sewers
and open bodies of water.

INSTABILITY:
This material is considered stable under specified conditions of
storage, shipment and/or use. See STORAGE AND HANDLING
INFORMATION Section for specified conditions. MEHQ is added as a
polymerization inhibitor. However, this material can undergo
hazardous polymerization. See Hazardous Polymerization for
conditions to avoid.

HAZARDOUS DECOMPOSITION PRODUCTS:
There are no known hazardous decomposition products for this
material.
HAZARDOUS POLYMERIZATION:
Excessive aging, heat, contamination with polymerization
catalysts, oxygen-free atmosphere, inhibitor depletion or
ultraviolet light (sunlight) may cause polymerization.
An uncontrolled polymerization may produce a rapid release of
energy with the potential for an explosion on unvented closed
containers.
INCOMPATIBILITY:
Acids, bases, oxidizing agents, reducing agents, free radical
initiators, organic peroxides, mild steel.

PERSONAL PROTECTION MEASURES
_________________________________________________________________
RESPIRATORY PROTECTION:
A respiratory protection program meeting OSHA 1910.134 and ANSI
Z88.2 requirements must be followed whenever workplace conditions
warrant a respirator's use. None required if airborne concen-
trations are maintained below the TWA/TLV's listed on the
COMPONENT EXPOSURE INFORMATION Section.
Up to 10 times the TWA/TLV: Wear a MSHA/NIOSH approved (or
equivalent) half-mask, air-purifying respirator.
Up to 100 times the TWA/TLV: Wear a MSHA/NIOSH approved (or
equivalent) full-facepiece, air-purifying respirator.
Above 100 times the TWA/TLV or Unknown: Wear a MSHA/NIOSH
approved (or equivalent) self-contained breathing apparatus in
the positive pressure mode, or MSHA/NIOSH approved (or
equivalent) full-facepiece airline respirator in the positive
pressure mode with emergency escape provisions.
Air-purifying respirators should be equipped with organic vapor
cartridges.
EYE PROTECTION:
Use chemical splash goggles and face shield (ANSI Z87.1 or
approved equivalent). Eye protection worn must be compatible
with respiratory protection system employed.
HAND PROTECTION:
The glove(s) listed below may provide protection against
permeation. Gloves of other chemically resistant materials may
not provide adequate protection: Nitrile, Neoprene.
Rinse and remove gloves immediately after use. Wash hands with
soap and water. Gloves should be removed and replaced
immediately if there is any indication of degradation or chemical
breakthrough.
NOTE: Material is a potential skin sensitizer.
OTHER PROTECTION: Use chemically resistant apron or other impervious
clothing to avoid prolonged or repeated skin
contact.
5
VENTILATION:
Use local exhaust ventilation with a minimum capture velocity of
100 ft/min. (30 m/min.) at the point of vapor evolution. Refer
to the current edition of Industrial Ventilation: A Manual of
Recommended Practice published by the American Conference of
Governmental Industrial Hygienists for information on the design,
installation, use and maintenance of exhaust systems.
OTHER PROTECTIVE EQUIPMENT:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower.

STORAGE & HANDLING INFORMATION
_________________________________________________________________
STORAGE CONDITIONS:
The maximum recommended storage temperature for this material is
32oC/90oF. Store out of direct sunlight in a cool place. Keep
material dry. Moisture may affect product quality. Total
absence of oxygen will inactivate the inhibitor. Do not store
under oxygen-free environment. Leave air space over liquid
surface in all containers introducing air periodically if stored
more than 6 months. Use monomer within 1 year. Conduct a
stability test on material stored in bulk every month; drums and
pails every 3 months using test method TM-1011A available from
Electron Microscopy Sciences.
Do not store this material in containers made of mild steel.
HANDLING PROCEDURES:
This material is a potential skin sensitizer. See the PERSONAL
PROTECTION MEASURES Section prior to handling.
OTHER: Containers hazardous when empty. Since emptied containers
retain product residue (vapors and/or liquid) follow all
MSDS and label warnings even after container is emptied.
