A SECOND APPRAISAL OF METHODS FOR ESTIMATING SELF-REACTION HAZARDS

A literature survey was carried out to collect and evaluate test methods and test data on hazardous materials which undergo self-decomposition. Some thermal tests are regarded as valuable because they give quantitative data indicating the limit of thermal stability for specified materials. With the assistance of the CHETAH predictive scheme, a hazard evaluation was conducted on a selected group of compounds normally considered safe. Results showed a tendency to identify these safe materials as hazardous so as not to err in evaluating a truly hazardous compound. In a study of accidental polymerization of bulk chemicals, free radical polymerization involving olefins was considered the polymerization process most likely to occur inadvertently during transport. A calorimetric test procedure appeared to offer the promise of yielding data from which an unambiguous reactivity scale could be developed. The test procedure should have a firm relationship to the theory of thermal explosion.
