VAPOR DENSITY: 3.5 EVAPORATION RATE: N.E. SOLUBILITY IN WATER: Slight. ODOR THRESHOLD: < 1 ppm as Methyl Methacrylate COEFFICIENT OF OIL/WATER DISTRIBUTION: N.E. APPEARANCE AND ODOR: Colorless volatile liquid with sweet sharp odor SECTION 4 - FIRE AND EXPLOSION DATA FLASH POINT: 11°C (ASTM D56-70) (Closed Cup) FLAMMABLE LIMITS: N.E. EXTINGUISHING MEDIA: Foam, carbon dioxide, dry chemical, water fog SPECIAL FIRE FIGHTING PROCEDURES: Full protective equipment, including self-contained breathing apparatus. UNUSUAL FIRE AND EXPLOSION HAZARDS: When heated above the flashpoint, emits vapors, which when mixed with air, can burn or be explosive. Fine mists or 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. HAZARDOUS DECOMPOSITION OR BY-PRODUCTS: None known 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 SECTION 6 - HEALTH HAZARD DATA and FIRST AID INFORMATION - continued ROUTES OF ENTRY: Inhalation Skin Ingestion HEALTH HAZARD (Acute and Chronic): INHALATION: May cause nose and throat irritation.

INGESTION: May cause abnormal liver and kidney function EYES: May cause irritation or burning SKIN: May cause irritation or burning of skin, and mucous membranes. Repeated exposure may cause skin burns and allergic reactions. SIGNS AND SYMPTOMS OF OVEREXPOSURE: Inhalation overexposure: headache, dizziness, nausea, staggering gait, confusion, unconsciousness. CONDITIONS GENERALLY AGGRAVATED BY EXPOSURE: N.E. EMERGENCY FIRST AID PROCEDURES: INGESTION: If ingested, do not induce vomiting. Give one or two glasses of water and seek medical attention. INHALATION: Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Seek medical attention. EYES: Immediately flush eyes with water. Seek medical attention. SKIN: Wash with soap and water. 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.
