COMPONENTS <br /> Material CAS Number Percent • <br /> 'SODIUM CYANIDE 143-33-9 99 <br /> 40 Regulated as a Toxic Chemical under Section 313 of Title III of the Superfund Amendments and Reauthorization Act of 1986 and <br /> CFR part 372. <br /> PHYSICAL DATA <br /> Boiling Point 1,496°C (2,725°F) at 760 mm Hg. <br /> Vapor Pressure Negligible <br /> Vapor Density Not volatile <br /> Melting Point 564°C (1,047°F) <br /> Water Solubility 37 WT%at 200C (68°F) <br /> pH 1 1 -11.7 Typical for 5-25%solutions-no pH adjustment <br /> Form Solid, granular or briquettes <br /> Color White <br /> Specific Gravity 1.6 <br /> Odor None (but can have slight ammonia and/or <br /> hydrogen cyanide odor if damp) . <br /> HAZARDOUS REACTIVITY <br /> Instability Very stable when dry. <br /> Decomposition Moisture will cause slow decomposition, releasing poisonous <br /> hydrogen cyanide and ammonia gases. <br /> Polymerization Polymerization will not occur. <br /> Incompatibility : Large amounts of poisonous, flammable <br /> hydrogen cyanide (HCN) gas will be <br /> evolved from contact with acids. Reacts <br /> violently with strong oxidizing agents. <br /> Water or weak alkaline solution can <br /> produce dangerous amounts of hydrogen <br /> cyanide in confined areas. <br /> FIRE AND EXPLOSION DATA <br /> Will not burn. <br /> Fire and Explosion Hazards Will not burn. Sodium cyanide will not be destroyed in an <br /> ordinary fire involving combustible materials such as paper <br /> or wood. Follow appropriate National Fire Protection <br /> Association (NFPA) codes. <br /> (continued) <br /> 1252CR P-ige 2 <br />
