LD50=5888 mg/kg (oral rat) LC50=N.E. 16 SECTION 3 - PHYSICAL/CHEMICAL PROPERTIES BOILING POINT: 101°C SPECIFIC GRAVITY (H2O = 1): 1 VAPOR PRESSURE: N.E. MELTING POINT: N.A. VAPOR DENSITY: N.E. ODOR THRESHOLD: <1 ppm methyl methacrylate SOLUBILITY IN WATER: Insoluble APPEARANCE AND ODOR: Clear liquid, unpleasant odor. COEFFICIENT OF OIL/WATER DISTRIBUTION: N.E. EVAPORATION RATE (Butyl Acetate=1): Equal SECTION 4 - FIRE AND EXPLOSION DATA FLASH POINT: 11°C/52°F FLAMMABLE LIMITS: N.E. EXTINGUISHING MEDIA: Alcohol foam, dry chemical, carbon dioxide SPECIAL FIRE FIGHTING PROCEDURES: Wear self-contained breathing apparatus with full protective equipment. UNUSUAL FIRE AND EXPLOSION HAZARDS: When heated above the flashpoint: emits vapors, which when mixed with air, can burn or be explosive. Fine mists on sprays may be flammable at temperatures below the flash point. Sealed containers exposed to elevated temperatures may rupture explosively due to polymerization. Vapors are heavier than air and may travel to ignition source. HAZARDOUS COMBUSTION PRODUCTS: Carbon dioxide, carbon monoxide, smoke SECTION 5 - REACTIVITY DATA STABILITY: Stable Unstable Polymerization: Will Not Occur Will Occur CONDITIONS TO AVOID: Heat and ignition sources INCOMPATIBILITY (Materials to Avoid): Reducing and oxidizing agents. Material has strong solvent properties and can soften paint or rubber. HAZARDOUS DECOMPOSITION OR BY-PRODUCTS: Carbon monoxide, carbon dioxide SECTION 6 - HEALTH HAZARD DATA and FIRST AID INFORMATION YES NO NE NA NTP IARC OSHA OTHER MUTAGENIC AFFECTS X TERATOGENIC AFFECTS X REPRODUCTIVE TOXIN X CARCINOGENICITY X SENSITIZER X ROUTES OF ENTRY: Inhalation Skin Ingestion HEALTH HAZARD (Acute and Chronic): INHALATION: May cause nose and throat irritation. May cause nervous system depression. Reports have associated repeated and prolonged overexposure to brain damage and nervous system damage. May cause irritation or burning of mucous membranes. INGESTION: May cause abnormal liver and kidney function SKIN: May cause irritation or burning of skin. Repeated exposure may cause skin burns and allergic reactions. EYES: May cause irritation or burning of eyes. SIGNS AND SYMPTOMS OF OVEREXPOSURE: Progressive steps of inhalation overexposure: headache, dizziness, nausea, staggering gait, confusion, unconsciousness. CONDITIONS GENERALLY AGGRAVATED BY EXPOSURE: N.E. EMERGENCY FIRST AID PROCEDURES: INHALATION: Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Seek medical attention. INGESTION: Do not induce vomiting. Give one or two glasses of water and seek medical attention. SKIN: Wash with soap and water. Wash clothes prior to reuse. EYES: Immediately flush eyes with water. Seek medical attention. SECTION 7 - PRECAUTIONS FOR SAFE HANDLING AND USE IN CASE OF RELEASE OR SPILL: Eliminate source of ignition. Wear skin, eye, respiratory protection. Contain spill and keep out of sewers. Use absorbent to soak up liquid. Use non-sparking equipment and shovel into waste container. WASTE DISPOSAL METHOD: Material is a hazardous waste, No. U162. Dispose of waste in facility permitted for hazardous waste in accordance with local, state and federal regulations. STORAGE, HANDLING, AND SPECIAL PRECAUTIONS: Keep away from heat, sparks, flame, direct sunlight and elevated temperatures. SECTION 8 - CONTROL MEASURES RESPIRATORY PROTECTION: Reduce exposure in accordance with safe hygiene practice. If exposure limits are exceeded, use a MSHA-NIOSH approved respirator for organic vapors. VENTILATION: Local Exhaust: Yes Mechanical: N.A. Special: N.A. Other: N.A. PROTECTIVE GLOVES: Disposable vinyl gloves EYE PROTECTION: Chemical eye goggles and full face protection if necessary. OTHER PROTECTIVE CLOTHING OR EQUIPMENT: Eye wash station WORK/HYGIENIC PRACTICE: Follow routine safe hygiene practices.
