Abstract

This invention provides a work machinery safety management system with which it is possible to improve, in a mode in which the effect is more immediate, the safety of a worksite at which work machinery is used. In order to achieve this, the work machinery safety management system according to an embodiment is provided with: a detection unit for detecting the entry of an obstacle into a prescribed region around work machinery; and an information generator for generating, on the basis of a detection results history for the detection unit and entry-related information relating to the entry when an obstacle enters the prescribed region, entry degree information for generating a table with which it is possible to identify the relationship between the degree of entry of an obstacle into the prescribed region and the entry-related information.
