**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Flammable. Harmful by inhalation, in contact with skin and if
swallowed. Causes severe burns. Very toxic to aquatic
organisms.Stench.
Potential Health Effects
Eye:
May result in corneal injury. Causes severe eye irritation and
burns. Direct contact with the liquid may cause blindness.
Skin:
Harmful if absorbed through the skin. May cause skin sensitization,
an allergic reaction, which becomes evident upon re-exposure to this
material. Causes severe skin irritation and burns.
Ingestion:
May be fatal if swallowed. May cause corrosion and permanent tissue
destruction of the esophagus and digestive tract.
Inhalation:
May cause liver and kidney damage. Causes chemical burns to the
respiratory tract. Vapors may cause dizziness or suffocation.
Inhalation of vapors causes nasal irritation. Acrylic acid caused
slight focal degeneration of the olfactory mucosa in mice exposed
intermittently at 5 ppm. It caused changes in respiratory rate and
volume in unanesthetized rats exposed at irritating concentrations.
Chronic:
Acrylic acid caused teratogenic and embryotoxic effects in rats
injected intraperitoneally at dose levels as low as 4.7 and 8 mg/kg
of body weight.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
In case of contact, immediately flush eyes with plenty of water for
at least 15 minutes. Get medical aid immediately.
Skin:
In case of contact, immediately flush skin with plenty of water for
at least 15 minutes while removing contaminated clothing and shoes.
Get medical aid immediately. Wash clothing before reuse.
Ingestion:
If swallowed, do NOT induce vomiting. Get medical aid immediately.
If victim is fully conscious, give a cupful of water. Never give
anything by mouth to an unconscious person.
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
**** SECTION 5 - FIRE FIGHTING MEASURES ****
General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. Water runoff can cause environmental damage. Dike
and collect water used to fight fire. Vapors may form an explosive
mixture with air. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. Use water
spray to keep fire-exposed containers cool. Flammable liquid and
vapor. May polymerize explosively when involved in a fire. May
accumulate static electrical charges, and may cause ignition of its
own vapors. Closed containers may rupture violently when heated.
Vapors are heavier than air and may travel to a source of ignition
and flash back. Vapors can spread along the ground and collect in
low or confined areas. Fight fire from protected location or maximum
possible distance.
Extinguishing Media:
Use water spray, dry chemical, "alcohol resistant" foam, or carbon
dioxide.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable container. Avoid runoff into storm sewers and
ditches which lead to waterways. Clean up spills immediately,
observing precautions in the Protective Equipment section. Remove all
sources of ignition. Use a spark-proof tool. Provide ventilation. Use
water spray to cool and disperse vapors, protect personnel, and
dilute spills to form nonflammable mixtures.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Ground and bond containers when transferring
material. Use spark-proof tools and explosion proof equipment. Do not
get in eyes, on skin, or on clothing. Empty containers retain product
residue, (liquid and/or vapor), and can be dangerous. Keep container
tightly closed. Discard contaminated shoes. Do not pressurize, cut,
weld, braze, solder, drill, grind, or expose empty containers to
heat, sparks or open flames. Do not use steam or electrical heating
systems such as coils, jackets, tapes, mantles, lights, etc. to thaw
any solidified monomer. The application of concentrated heat will
cause polymerization and possibly rupture the container. Keep away
from heat, sparks and flame. Do not breathe vapor or mist. Pure vapor
will be uninhibited and may polymerize in vents or other confined
spaces. Use only with adequate ventilation or respiratory protection.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of
ignition. Keep from freezing. Keep container closed when not in use.
Store in a cool, dry, well-ventilated area away from incompatible
substances. Flammables-area. Store only in glass, stainless steel,
aluminum or polyethylene-lined equipment. Separate from oxidizing
materials.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use explosion-proof ventilation equipment. Facilities storing or
utilizing this material should be equipped with an eyewash facility
and a safety shower. Use adequate general or local exhaust
ventilation to keep airborne concentrations below the permissible
exposure limits.
