Evaluation tools field trials

During the early 1970 s, W. G. Johnson (former General Manager of the National Safety Council) developed a more specialized version of Uie fault tree known as MORT (Management Oversi and Risk Tree) as an evaluative tool for safety professionals and their management. Its effectiveness has been veiibed in actual field trials. Its use is now mandatory within ERDA for the more severe classes of accidents. 

Resin chemistry is a mixture of thermodynamic and kinetic knowledge, semiempirical theory, and formulation art. Chemists have sought and continue to seek instrumental and other methods to predict performance prior to plant trials. Methods of chemical analysis, rheological characterization, mechanical analysis, pilot plant evaluation, fracture mechanics, and multivariate statistical analysis all are useful tools. Lab studies are generally designed to bracket the conditions which are likely to be encountered in field trials. When trends are identified, theoretical explanations are formulated.
