Section 3 - HAZARDS IDENTIFICATION
  EMERGENCY OVERVIEW
Highly flammable. Harmful by inhalation, in contact with skin and if swallowed. Irritating to eyes, respiratory system and skin. May cause sensitization by skin contact.Lachrymator (substance which increases the flow of tears).
Potential Health Effects
Eye:
Causes eye irritation. May result in corneal injury. Lachrymator (substance which increases the flow of tears).
Skin:
May cause skin sensitization, an allergic reaction, which becomes evident upon re-exposure to this material. Exposure may cause irritation and possible burns. May be harmful if absorbed through the skin.
Ingestion:
Harmful if swallowed. Causes gastrointestinal irritation with nausea, vomiting and diarrhea.
Inhalation:
May cause respiratory tract irritation. Inhalation of methyl acrylate vapor or mist may cause headache, nausea, vomiting, confusion, dizziness, and unconsciousness. High exposure can cause pulmonary edema (accumulation of fluid in the lungs).
Chronic:
Doses of 1, 5, and 20 mg/kg/day of methyl acrylate administered for 13 weeks in the drinking water of rats resulted in reduced weight gain and kidney effects in the highest dose group. The NOEL was 5 mg/kg/day. Inhalation exposure (6 hrs/day; 5 days/week) of rats to methyl acrylate vapor concentrations of 15, 45, or 135 ppm for 2 years resulted in irritation of the upper respiratory tract (nasal lesions) and the eyes at all levels.

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 soap and plenty of water. Remove contaminated clothing and shoes. Get medical aid if symptoms occur. 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:
Treat symptomatically and supportively.

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. Vapors may form an explosive mixture with air. Will burn if involved in a fire. Use water spray to keep fire-exposed containers cool. Containers may explode in the heat of a fire.
Flammable liquid and vapor. 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. This liquid floats on water and may travel to a source of ignition and spread fire.
Extinguishing Media:
Use water spray to cool fire-exposed containers. Water may be ineffective. Use dry chemical, carbon dioxide, or appropriate foam.

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. Clean up spills immediately, observing precautions in the Protective Equipment section. Remove all sources of ignition. Use a spark-proof tool. Provide ventilation. A vapor suppressing foam may be used to reduce vapors.

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. Avoid contact with eyes, skin, and clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep away from heat, sparks and flame. Avoid ingestion and inhalation. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames. Use only with adequate ventilation. Destroy contaminated leather clothing.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of ignition. Do not store in direct sunlight. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Refrigerator/flammables. Do not store under inert atmosphere. Separate from oxidizing materials. Inhibitor level should be checked periodically.

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.
Exposure Limits CAS# 96-33-3: United States OSHA: 10 ppm TWA; 35 mg/m3 TWA Belgium - TWA: 10 ppm VLE; 36 mg/m3 VLE France - VME: 10 ppm VME; 35 mg/m3 VME France - VLE: 15 ppm VLE; 50 mg/m3 VLE Germany: 5 ppm TWA; 18 mg/m3 TWA Germany: Skin absorber Japan: 2 ppm OEL; 7 mg/m3 OEL Malaysia: 2 ppm TWA; 7 mg/m3 TWA Netherlands: 5 ppm MAC; 18 mg/m3 MAC Russia: 5 mg/m3 TWA Spain: 2 ppm VLA-ED; 7.2 mg/m3 VLA-ED CAS# 150-76-5: Belgium - TWA: 5 mg/m3 VLE France - VME: 5 mg/m3 VME Germany: 5 mg/m3 TWA Malaysia: 5 mg/m3 TWA Netherlands: 5 mg/m3 MAC Spain: 5 mg/m3 VLA-ED CAS# 7732-18-5: Personal Protective Equipment Eyes: Wear chemical splash goggles.
Skin:
Wear appropriate protective gloves to prevent skin exposure.
Clothing:
Wear appropriate protective clothing to prevent skin exposure.
Respirators:
Follow the OSHA respirator regulations found in 29 CFR 1910.134 or European Standard EN 149. Use a NIOSH/MSHA or European Standard EN 149 approved respirator if exposure limits are exceeded or if irritation or other symptoms are experienced.
