Résumé : During the Non-Technical Survey, information on a Suspected Hazardous Area (SHA) is collected and analysed for assessment and reduction/inclusion purposes. This phase focuses on a scale that is more local than the Advanced General Survey (WP210). Unlike the Technical Survey, the Non-Technical Survey does not involve entering the SHA physically. This deliverable, entitled Non-Technical Survey Tool Performance evaluation report, is the fourth deliverable devoted to tools for Non-Technical Survey (NTS). It includes a description of the tools developed, the rationale and guidelines for using them and an evaluation of their performance. It is meant to be a reference document on WP220 tools and services after the project lifetime. Therefore, it is as much as possible self-contained and includes more than the description of the work achieved during the last period.
