SECTION 2 HAZARDS IDENTIFICATION
Emergency Overview: Flammable liquid and vapor. Hazardous polymerization may occur. May cause
respiratory tract, eye and skin irritation. Prolonged or repeated contact may cause allergic skin reaction
(skin sensitization). May be harmful if swallowed, inhaled or absorbed through the skin. Inhalation of
vapors may cause dizziness, headache, and other central nervous system effects. Absorption may cause
effects on the blood (methemoglobinemia). Effects may be delayed.

SECTION 4 FIRST AID MEASURES
Eye Contact: Flush eyes with large quantities of water for at least 15 minutes, holding the eyelids apart.
Get immediate medical attention.
Skin Contact: Remove contaminated clothing. Wash skin thoroughly with soap and water. If irritation or
other symptoms develops, get medical attention. Launder clothing before re-use. (Discard contaminated
shoes).

Ingestion: Get immediate attention. Do not induce vomiting unless directed to do so by medical
personnel. Never give anything by mouth to an unconscious or convulsing person.
Inhalation: Remove victim to fresh air. If breathing is difficult have qualified personnel administer oxygen.
If breathing has stopped, administer artificial respiration. Get immediate medical attention.
SECTION 5 FIRE FIGHTING PROCEDURES
Extinguishing Media: Use carbon dioxide, foam, water spray or water fog.
Firefighting Procedures: Do not enter fire area without proper protection. Fight fire from safe distance or
protected location. Firefighters should wear full emergency equipment and approved positive pressure
self-contained breathing apparatus. Water may be ineffective unless used as a fine spray or fog. Use
water to cool fire-exposed containers.
Unusual Fire/Explosion Hazards: Vapors are heavier than air and may travel to ignition source and flash
back. Heat of fire may cause an exothermic autopolymerization reaction. Emits toxic fumes under fire
conditions. Closed containers may explode due to pressure build up when exposed to extreme heat.
Known or Anticipated Hazardous Products of Combustion: Carbon monoxide, carbon dioxide, nitrogen
oxides, methyl methacrylate, and irritating smoke and fumes.
SECTION 6 ACCIDENTAL RELEASE MEASURES
Accidental Release Measures: Provide explosion-proof ventilation. Wear appropriate protective clothing
as described in Section 8. Eliminate all ignition sources. Contain and absorb spills with inert material and
transfer to a suitable container for disposal. Do not allow spills to be released into the environment.
Personal Precautions: Avoid contact with skin, eyes or clothing. Avoid breathing vapors.
Environmental Precautions: Do not allow spills to enter sewers or waterways.
SECTION 7 HANDLING AND STORAGE
Handling: Avoid contact with eyes, skin, and clothing. Avoid breathing vapors or mist. Wash thoroughly
after handling. Wear protective clothing and equipment as described in Section 8. Use with adequate
ventilation. Keep away from heat, sparks and flames. Ground container when pouring. Do not expose to
direct sunlight.
Empty containers retain product residues can be hazardous. Follow all MSDS precautions when handling
empty containers.
Storage: Store in a cool, dry, well ventilated area. Keep container tightly closed when not in use. Do not
store in direct sunlight. Prevent moisture contact. Protect from physical damage. Keep away from
oxidizers and other incompatible materials.

Engineering Controls: Use ventilation that is adequate to keep employee exposure to airborne
concentrations below exposure limits. Use explosion-proof equipment where required.
Personal Protective Equipment:
Eye Protection: Wear safety chemical goggles when the possibility exists for eye contact due to splashing
or spraying material.
Skin Protection: Wear nitrile rubber or other impervious gloves to prevent skin contact.
Respiratory Protection: A NIOSH/MSHA approved air-purifying respirator with an organic vapor cartridge
or canister may be permissible under certain limited circumstances where airborne concentrations are
expected to exceed exposure limits. Protection provided by air purifying respirators is limited. Use a
positive pressure air supplied respirator if there is any potential for an uncontrolled release, exposure
levels are not known, or any other circumstances where air purifying respirators may not provide adequate
protection. Selection and use of respiratory equipment must be in accordance with appropriate regulations
and good industrial hygiene practice.
Other Protective Clothing or Equipment: Wear impervious clothing to prevent any contact with this
product, such as gloves, apron, boots, or whole body suit.

SECTION 10 STABILITY AND REACTIVITY
Stability: Stable
Conditions to Avoid (stability): Heat, sparks, open flame and other ignition sources, elevated
temperatures, direct sunlight.
Incompatibility with Other Materials: Avoid contact with oxidizing agents, reducing agents, acids, and
bases.
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, nitrogen oxides, methyl
methacrylate, and irritating smoke and fumes.
Hazardous Polymerization: Polymerization can occur. Conditions leading to polymerization are excessive
heat, oxygen-free atmosphere inhibitor depletion (due to excessive aging), direct sunlight, and
contamination with polymerization catalysts.
SECTION 11 TOXICOLOGICAL INFORMATION
Potential Health Effects:
Eyes: Liquid and vapors can cause irritation with redness, tearing and blurred vision. Corneal damage can
occur.
Skin: May cause skin irritation with allergic skin reaction (skin sensitization). May be harmful if absorbed
through the skin causing effects similar to inhalation.
Inhalation: May cause respiratory tract irritation with coughing, mucous production and shortness of
breath. High concentration is irritating to the respiratory tract and may cause dizziness, headache and
anesthetic effects. Absorption may cause effects on the red blood cells resulting in methemoglobinemia
(reduction in the oxygen carrying capacity of the blood). Symptoms, which may be delayed, include
headache, weakness, confusion, palpitations, chest pain, discoloration of the skin and blood and seizures.
