The authors extracted five fundamental principles of fool proofs from many examples. These are "elimination", "substitution", "facilitation", "detection of errors" and "relaxation of effects". In this article and next one, authors discuss how to apply them to actual problems in manufacturing. This article deals with the fool proof methods to prevent human errors by "substitution" and "facilitation". Human errors are classified into three qroups, that is, errors in memories, errors in perceptions and errors in motions. Practical application of these two principles are investigated on each of three groups. These are (a) link, directions and records, regularization, grouping, calling attention, reducing and shortenning memory. (b) mechanization, samples and gauges, unification and symmetrization, matching, specialization, labeling, proper indication. (c) mechanization, guide. flatting, specialization, differentiating motions, proper objects and spaces. Examples are shown and examined.
