Emergency Overview

Color:	colorless, turbid
Appearance:	low-viscosity
Odor:	sweet, ester-like

Flammable liquid and vapor.

Irritating to respiratory system and skin.

May cause sensitization by skin contact.

May be ignited by heat, sparks or flame.

Vapors can travel to a source of ignition and flash back.

Danger of bursting of closed systems due to vigorous exothermic polymerization.

Avoid uncontrolled polymerization.

Container may explode when heated.

Primary Routes of Exposure – Inhalation and skin contact.

Potential Health Effects:

Inhalation - May cause irritation to the respiratory tract.

Eye Contact – May cause eye irritation.

Skin contact - May cause irritation and sensitization of the skin. Not expected to be absorbed through the skin in toxic amounts.

Ingestion - Expected to be slightly toxic by ingestion.

Chronic Effects - No chronic (long-term) effects are known for humans.

Aggravated Medical Conditions - Conjunctivitis of the eye, dermatitis of the skin, asthma and respiratory diseases.

Potential Environmental Effects - See SECTION XII, Ecological Information

SECTION IV – FIRST AID MEASURES

First Aid Procedures

Inhalation – Remove to fresh air. If irritation persists, call a physician. Administer oxygen if breathing is difficult. Apply artificial respiration if victim is not breathing.

Eye Contact – In case of contact, immediately flush eyes with plenty of water for at least 20 minutes. Hold eyelids apart during flushing to ensure rinsing of the entire surface of the eye with water. Obtain medical attention if irritation develops or persists. DO NOT WEAR CONTACT LENSES WHEN USING THIS PRODUCT.

Skin Contact – In case of contact, wash skin with water and soap. If irritation persists, call a physician.

Ingestion –Call a Poison Control Center or doctor immediately. Do NOT induce vomiting.

Lower Explosion Limit	2.1% (V) (methyl methacrylate)
Upper Explosion Limit	12.5% (V) (methyl methacrylate)

OSHA Flammability Classification – Flammable liquid

Other Flammable Properties – Vapors are heavier than air and can form an explosive mixture with air. Never use welding or cutting torches on or near containers or drums (even when empty). Product residue or vapor in drums or container can ignite explosively. Cool warm or bulging containers to ambient temperature with water from a safe distance. Then wear eye and face protection and protective clothing while carefully opening bung to vent pressure.

Extinguishing Media – Use the following extinguishing media when fighting fires involving this material: alcohol-resistant foam – dry chemical – carbon dioxide.

Fire Fighting Procedures – Evacuate enclosed and surrounding areas. As in any fire, wear self-contained breathing apparatus pressure-demand, MSHA/NIOSH (approved or equivalent) and full protective gear. Use water spray to cool containers exposed to fire and disperse vapors. Keep spills away from sources of ignition.

SECTION VI – ACCIDENTIAL RELEASE MEASURES

Procedures – Remove sources of ignition and ventilate area. Dike far ahead of spill for later disposal. All equipment used when handling the product must be grounded. Absorb spill with inert material and place in a chemical waste container. Obey relevant local, state, provincial and federal laws and regulations. Do not contaminate any lakes, streams, ponds, groundwater or soil. See Section VIII, Exposure Controls/Personal Protection.

SECTION VII – HANDLING AND STORAGE

Handling – Product is supplied in a stabilized form. Stir well before decanting from drum. Open container carefully as it may be pressurized. Use portable ventilation if necessary at job site. Ground and bond containers when transferring material. Keep container tightly closed. Use explosion-proof equipment. Do not eat, drink, smoke or chew tobacco around material.

Storage – Keep in the original container at a temperature not exceeding 25° C (77° F). Do not store in direct sunlight. Keep away from heat. Keep away from sparks, flames and other sources of ignition. Keep container closed when not in use. Ensure the area is well ventilated. Limit storage of flammable liquids to approved areas equipped with overhead sprinklers. Protect material from contamination (refer to Section X for incompatibilities). Fill the container by approximately 80% only as oxygen (air) is required for stabilization. With large storage containers make sure the oxygen (air) supply is sufficient to ensure stability. Residual vapors might explode on ignition; do not apply heat, cut, drill, grind or weld on or near this container.

Engineering Controls (Ventilation) – Provide general and/or exhaust ventilation to maintain airborne levels below the exposure limits in Section VIII. Refer to the current edition of ‘Industrial Ventilation: A Manual of Recommended Practice’ published by the American Conference of Government Industrial Hygienists for information on the design, installation, use, and maintenance of exhaust systems.

Respiratory Protection – A respiratory protection program that meets OSHA 1910.134 and ANSI Z88.2 or applicable federal/provincial requirements must be followed whenever workplace conditions warrant respirator use. NIOSH’s “Respirator Decision Logic” may be useful in determining the suitability of various types of respirators.
