known allergies to methacrylates and acrylates may develop allergic response. Inhalation: High vapor concentration can
induce headache, nausea, smarting of eyes and irritation of respiratory system. Eyes: Liquid contact with eyes will cause
irritation and possible corneal damage. Skin: Material may cause sensitization by skin contact. Repeated and/or prolonged
contact may cause dermatitis. Ingestion: Low oral toxicity but ingestion may cause irritation of the gastrointestinal tract.

All components of this product are in compliance with the inventory listing requirements of the U. S. Toxic Substances
Control Act (TSCA) Chemical Substance Inventory.

stopped. Ingestion: If swallowed and conscious, give 2 glasses of water to drink and consult a physician immediately.
Eyes: Flush eyes promptly with copious amounts of water for 15 minutes and consult physician if irritation is apparent.
Skin Contact: Wash skin with soap and water. See a physician if irritation persists.
SECTION VII 鈥? Special Precautions and Spill or Leak Procedures
7.1 Handling and Storage Precautions: Do not breathe vapors or mist. Do not get in eyes, on skin or clothing. Wash
thoroughly after handling. Close container after each use. Store at ambient temperatures out of direct sunlight/advisable
to use oldest materials first. Use adequate ventilation. Do not store under O2-free environment. Vapors are uninhibited
and may form polymers in vents or flame arrestors, resulting in blockage of vents.
7.2 Waste Disposal Procedures: After addition of excess inhibitor, incinerate under controlled conditions in a safe open
area, according to Federal, State and Local regulations.
7.3 Steps to be Taken in Case Material is Released or Spilled:Eliminate ignition sources. Avoid breathing vapors. Dike
and absorb spill with inert material (sand, soda, ash, vermiculite, etc.) and transfer to containers for disposal; use non-
sparking tools. Contaminated monomer may be unstable; addition of inhibitor will prevent polymerization. Remove
saturated clothing and wash affected skin areaswith soap and water.
7.4 Other Precautions: Avoid repeated breathing and contact with the skin. Keep containers closed and away from heat.
Keep away from sparks and open flame. Keep container in a cool place. Do NOT expose to direct sunlight. Store in a
well-ventilated place. Keep container tightly closed. Store in accordance with NFPA National Fire Protection Association
recommendations. Avoid contact with skin. Observe normal warehouse handling procedures. Handling of this product
should be by trained dental healthcare professionals only.
SECTION VIII 鈥? Control Measures / Personal Protection
8.1 Respiratory protection: None required if airborne concentrations are maintained below TLV listed in Section II. For
airborne concentrations up to 10 times the TLV (1000 ppm), wear a MSHA/NIOSH approved (or equivalent) half mask,
air-purifying respirator. (Air-purifying respirators should be equipped with organic vapor cartridges and dust and mist
fibers.) For airborne concentrations up to 100 times (10,000 ppm), wear a MSHA/NIOSH approved full facepiece airline
respirator in the positive pressure mode with emergency escape provisions. For unknown concentrations or those above
10,000 ppm, wear a self-contained breathing apparatus in the positive pressure mode.
8.2 Ventilation: Use ventilation that is adequate to keep employee exposure to airborne concentrations below exposure limits.
Mechanical ventilation should have explosion-proof motors.
8.3 Protective gloves: Impervious gloves; nitrile rubber is better than PVC, (butyl rubber preferred).
8.4 Eye protection: Splash proof goggles (ANSI Z87.1 or approved equivalent).
8.5 Other Personal Protective Equipment: Use chemically resistant apron and overshoes to avoid prolonged or repeated
skin contact.
8.6 Work/Hygienic practices: Observe normal care when working with chemicals. Avoid eye and skin contact, inhalation
and ingestion. Do not eat, drink or smoke when using.
