A Method for Determining the Compatibility of Hazardous Wastes

摘要

This report describes a method for determining the compatibility of the binary combinations of hazardous wastes. The method consists of two main parts, namely: (1) the step-by-step compatibility analysis procedures, and (2) the hazardous wastes compatibility chart. The key element in the use of the method is the compatibility chart. Wastes to be combined are first subjected through the compatibility procedures for identification and classification, and the chart is used to predict the compatibility of the wastes on mixing. The chart consists of 41 reactivity groups of hazardous wastes designated by Reactivity Group Numbers (RGN). The RGN are displayed in binary combinations on the chart, and the compatibility of the combinations are designated by Reaction Codes (RC). The method is applicable to four categories of wastes based on available compositional information: (1) compositions known specifically, (2) compositions known nonspecifically by chemical classes or reactivities, (3) compositions known nonspecifically by common or generic names of wastes, (4) compositions unknown requiring chemical analysis.
