Gertlg, water Production Manageru Revision Date: December 3, 2004 Chuck Gross, Plant Superintendent PURPOSE Establish guidelines for purchasing Sodium Chlorite (NaC102) for the Fort Collins Water Treatment Facility (FCWTF). The mission of the Fort Collins Water Treatment Facility (FCWTF) is to "provide the community with a continuous ample supply of treated water that is pleasing, wholesome, free from known health risks, and affordable." The FCWTF purchases products by determining best value for the City. Best value is calculated by combining the following four components: (1) the chemical has been tested in the Pilot Plant and/or approved by the Water Treatment Quality Coordinator; (2) the chemical can meet or exceed all FCWTF standards, the AWWA standards, the NSF standards, and any other regulatory agency standards; (3) the supplier can meet all the FCWTF requirements; and (4) the cost is factored in once it has been determined that a supplier can meet items (1), (2), and (3) above. HEALTH AND SAFETY ISSUES For detailed information, please refer to the MSDS 1. Sodium chlorite solution is corrosive. The liquid can bum the skin and eyes on contact. Sodium chlorite solution is a REACTIVE CHEMICAL and is an EXPLOSION HAZARD when mixed with organic material or acids. 2. NFPA Hazard Rating includes: • Health=3 • Flammability=0 • Reactivity=1 3. Personal Protective Equipment: • Impervious gloves and goggles. If there is prolonged or repeated contact, completely impervious clothing should also be used. 4. Leaks and Spills: • Dilute small spills or leaks with plenty of water. • Wash down any spilled material into the containment vault and follow Operations procedures. • Notify supervisor. !l�MEP1y `♦ '��I Page I �I Oil K 1OPerateJSOP/Chlorine/SodiumChicritePurchasetdoc III[ N! ® Fort Collins Water Treatment Facility Standard Operating Procedure Utilities Purchasing Sodium Chlorite INFORMATION FOR THE FORT COLLINS WATER TREATMENT FACILITY (FCWTF) 1.
