Caution: This Chart is intended as an indication of some of the hazards that can be expected on mixing chemical wastes. Because of the differing activities of the thousands of compounds that may be encountered, it is not possible to make any chart definitive and all inclusive. It cannot be assumed to ensure compatibiltiy of wastes because wastes are not sclassified as hazardous on the chart, nor do any blanks necessarily mean that the mixture cannot result in a hazard occuring. Detailed instructions as to hazards involved in handling and disposing of any given waste should be obtained from the originator of the waste.
