Data included in <br /> the table are formulas,CAS numbers,oral Id50 values for <br /> rats and PEL/TWA values if available. Total concentration <br /> of purgeable aromatic compounds in the standard is less <br /> than 2% with individual compound concentrations of less <br /> than 0.1%. <br /> Non-Hazardous Ingredients/Identity Information <br /> Chemical Name CAS Reg.No. OSHA PEL(TWA) %Composition* <br /> *Components are calculated on a weight/weight basis. <br /> Section III - Physical/Chemical Characteristics of Hazardous Ingredients <br /> BOILING POINT: 65 C(149 F) SPECIFIC GRAVITY: (water=1)0.79 <br /> VAPOR PRESSURE: 97 mmHg @ 20 C SOLUBILITY IN WATER: Complete APPEARANCE/ODOR: Clear,colorless liquid with <br /> pungent odor(methanol). <br /> Section IV- Fire and Explosion Hazard Data <br /> FLASH POINT(Method used): 12 C(54 F)Closed AUTO IGNITION TEMPERATURE: 463 C(867 F) FLAMMABLE LIMITS I LEL 6% UEL 36% <br /> cup <br /> EXTINGUISHING MEDIA: Use extinguisher media appropriate for surrounding fire since sample size is small. Alcohol foam,dry chemical or carbon dioxide(water may <br /> be ineffective in most laboratory situations.) <br /> SPECIAL FIRE FIGHTING PROCEDURES: Firefighters should wear proper protective equipment and self-contained breathing apparatus with full face piece operated in <br /> positive pressure mode. Move containers from fire area if it can be done without risk. Use water to keep fire exposed containers cool. <br /> UNUSUAL FIRE AND EXPLOSION HAZARDS: Vapors may flow along surfaces to distant ignition sources and flash back. Closed containers exposed to heat may <br /> explode. Contact with strong oxidizers may cause fire. Burns with a clear,almost invisible flame. <br /> Section V- Reactivity Data <br /> Unstable ❑ Stable ® Conditions to Avoid: Heat,flame and other sources of ignition. <br /> STABILITY: <br /> INCOMPATIBILITY(Materials to avoid): <br /> String oxidizing agents,strong acids,zinc,aluminum and magnesium. <br /> HAZARDOUS DECOMPOSITION PRODUCTS: Carbon monoxide,carbon dioxide and formaldehyde. <br /> HAZARDOUS May Occur ❑ Will Not Occur ® Conditions to Avoid: N/A <br /> POLYMERIZATION: <br />
