Provided is an empirical method to train students to avoid physical disaster in their work experience. Discussed is a computer program, CHETAH, which can be used in advance of synthesis to classify the possible explosive nature of the products. Plosophoric and auxoplosive weights of many organic groups are listed. (MVL)
