3 HAZARDS IDENTIFICATION
Emergency Overview
Clear liquid with pungent odor
DANGER!
CAUSES EYE AND SKIN BURNS. MAY CAUSE BLINDNESS.
CAUSES RESPIRATORY TRACT IRRITATION.
HARMFUL IF ABSORBED THROUGH SKIN.
Potential Health Effects
Inhalation and skin contact are expected to be the primary routes of occupational exposure to this material. Based on
single exposure animal tests, it is considered to be no more than slightly toxic if swallowed, no more than moderately
toxic if absorbed through skin, practically non-toxic if inhaled and corrosive to eyes and skin. Exposure to vapor may
cause severe respiratory tract irritation.

4 FIRST AID MEASURES
IF IN EYES, immediately flush with plenty of water for at least 15 minutes. Get medical attention immediately.
IF ON SKIN, immediately flush with plenty of water. Remove contaminated clothing and shoes. Get medical
attention. Wash clothing before reuse. Destroy contaminated shoes.
IF SWALLOWED, do NOT induce vomiting. Give water to drink. Get medical attention immediately. NEVER
GIVE ANYTHING BY MOUTH TO AN UNCONSCIOUS PERSON.
IF INHALED, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give
oxygen. Get medical attention. Call a Poison Control Center.

Extinguishing Media
Use water spray, carbon dioxide, foam or dry chemical.
Fire Fighting Instructions
Fight fire from a protected location - EXPLOSION HAZARD. Fire fighters and others who may be exposed to
products of combustion should wear full fire fighting turn out gear (full Bunker Gear) and self-contained breathing
apparatus (pressure demand NIOSH approved or equivalent). Fire fighting equipment should be thoroughly
decontaminated after use.
Fire and Explosion Hazards
When burned, the following hazardous products of combustion can occur:
Oxides of carbon
A large amount of heat can be generated when monomers are exposed to a fire. Heated sealed containers can
explode.
6 ACCIDENTAL RELEASE MEASURES
In Case of Spill or Leak
Stop the leak if you can do so without risk. Ventilate the area and remove all ignition sources. Contain the
spill by building a dike using absorbent material. Collect the liquid and solid absorbent into a drum approved
for waste disposal. Contaminated monomer may be unstable. Add inhibitor to prevent polymerization.
The product can be neutralized with sodium bicarbonate, lime, or soda ash. CAUTION: neutralization of the
acid may result in an exothermic reaction, accompanied by some spattering of unreacted material. Consult a
regulatory specialist to determine appropriate state or local reporting requirements, for assistance in waste
characterization and/or hazardous waste disposal and other requirements listed in pertinent environmental
permits.

7 HANDLING AND STORAGE
Handling
Do not get in eyes, on skin or on clothing.
Avoid breathing vapor.
Do not taste or swallow.
Keep container closed.
Use only with adequate ventilation.
Wash thoroughly after handling.
Emptied container retains vapor and product residue. Observe all labeled safeguards until container is
cleaned, reconditioned or destroyed. DO NOT CUT OR WELD ON OR NEAR THIS CONTAINER.
Storage
This product should be stored in a closed container, away from direct sunlight, at ambient temperatures.
Storage of this product at elevated temperatures (>30 C or >85 F) reduces the shelf-life. The typical shelf-life
for this product is 12 months. An air space is required above the liquid in all containers; avoid storage under
an oxygen-free atmosphere.
The stability of this product should be checked periodically; typically every 90 days for bulk containers.
Materials recommended for packaging include: stainless steel, aluminum, glass, HDPE, PP or PTFE.
8 EXPOSURE CONTROLS / PERSONAL PROTECTION
Engineering Controls
Investigate engineering techniques to reduce exposures below airborne exposure limits. Provide ventilation
if necessary to control exposure levels below airborne exposure limits (see below). If practical, use local
mechanical exhaust ventilation at sources of air contamination such as open process equipment. Consult
ACGIH ventilation manual or NFPA Standard 91 for design of exhaust systems.
Eye / Face Protection
Where there is potential for eye contact, wear a face shield, chemical goggles, and have eye flushing
equipment immediately available.
Skin Protection
Wear appropriate chemical resistant protective clothing and chemical resistant gloves to prevent skin
contact. Butyl rubber Gloves should be worn when handling this material. Wear chemical goggles, a face
shield, and chemical resistant clothing such as a rubber apron when splashing may occur. Rinse immediately
if skin is contaminated. Remove contaminated clothing promptly and wash before reuse. Clean protective
equipment before reuse. Provide a safety shower at any location where skin contact can occur. Wash skin
thoroughly after handling.
Respiratory Protection
Avoid breathing vapor or mist. When airborne exposure limits are exceeded (see below), use NIOSH
approved respiratory protection equipment appropriate to the material and/or its components. Consult
respirator manufacturer to determine appropriate type equipment for given application. Observe respirator
use limitations specified by NIOSH or the manufacturer. For emergency and other conditions where
exposure limit may be significantly exceeded, use an approved full face positive-pressure, self-contained
breathing apparatus or positive-pressure airline with auxiliary self-contained air supply. Respiratory
protection programs must comply with 29 CFR ?1910.134.

Stability
This material is chemically stable under normal and anticipated storage and handling conditions. However,
this material can undergo hazardous polymerization. See Hazardous Polymerization below for conditions to
avoid.
Hazardous Polymerization
An uncontrolled polymerization may produce a rapid release of energy with the potential for an explosion of
unvented closed containers or inadequately vented containers.
Incompatibility
This material polymerizes exothermically in the presence of heat, contamination, oxygen free atmosphere, free
radicals, peroxides, and inhibitor depletion liberating heat.
Hazardous Decomposition Products
Oxides of carbon can be liberated at temperatures above ambient.

Eye Irritation - Corrosive to Rabbits
Skin Irritation - Corrosive to Rabbits (24-hr exposure)
No skin allergy was observed in guinea pigs following repeated exposure. Adverse effects noted in rats
following repeated inhalation include eye and nose irritation with weight loss and kidney congestion. Repeated
inhalation exposure produced nasal injury in rats and mice and kidney effects in mice. Repeated oral
administration in rats produced changes in the liver and lung. No genetic changes were observed in tests using
bacteria.
