FIRE FIGHTING MEASURES <br />Flammable Properties <br />Will not burn. <br />Follow appropriate National Fire Protection Association (NFPA) <br />codes. <br />Sodium Cyanide may not be completely destroyed in an <br />ordinary fire involving combustible materials such as paper <br />or wood. While sodium cyanide does not support combustion, <br />it can oxidize in a fi ire. <br />• <br />Extinguishing Media <br />Water can be used on fiires near sodium cyanide, but judgment <br />should be used in light of runoff problems, especially if <br />containers are opened or burned (See "Incompatibility with <br />.:Other Materials" and "Fire Fighting Instructions"). In some <br />cases it may be desirable to let afire burn out by itself. <br />DO NOT use carbon dioxide (C02) which reacts with sodium <br />cyanide to produce hydrogen cyanide in the presence of <br />moisture. <br />Fire Fighting Instructions <br />Sodium Cyanide dissolves readily in water; therefore, <br />cyanide solution runoffi may occur if containers are opened <br />or burned. Runoff should be contained to avoid <br />environmental or safety problems. Contained cyanide <br />solution can be detoxif ied with hypochlorite. In some cases <br />it may be desirable to let afire burn out by itself since <br />sodium cyanide will. not normally be affected by the fire. <br />ACCIDENTAL RELEASE MEASURES <br />Safeguards (Personnel) <br />NOTE: Review FIRE FIGHTING MEASURES and HANDLING (PERSONNEL) <br />sections befiore proceeding with clean-up. Use appropriate <br />PERSONAL PROTECTIVE EQUIPMENT during clean-up. <br />Spill Clean Up <br />Shovel and sweep up spilled material into a covered container or <br />plastic bag pending transfer. Cover and keep spillage dry. Flush <br />spill area with a dilute solution of sodium hypochlorite or <br />calcium hypochlorite to destroy the cyanide. Call DuPont for <br />°guidance. Comply with Federal, State, and local regulations <br />reporting releases. The EPA Reportable Quantity (RQ) is 10 pounds. <br />HANDLING AND STORAGE <br />Handling (Personnel) <br />Emergency pre-planning and training are needed before <br />beginning to work with sodium cyanide since prompt treatment <br />is essential in cases ofi cyanide poisoning. Always have <br />Cyanide Antidote on hand. <br />(Continued) <br />C, <br />1252CR <br />Page 10 <br />
