The AMRISK version 1.2 User´s Guide is presented in this report. The purpose of the User´s Guide is to give a user guidance and information about how to perform a risk analysis of ammunition storage by using the AMRISK code. The AMRISK code is a tool for Explosives Safety Quantitative Risk Analysis (ESQRA) in Norway and Sweden for calculating risk values for persons in the vicinity of ammunition storages. AMRISK version 1.1 and 1.2 is a result of a joint Norwegian-Swedish development of the originally Swiss code AMMORISK, which has been used in Norway since 1985. AMRISK has been used in Sweden since 1999. AMRISK version 1.1 ß was mainly a Windows-version of the old DOS-code (version 1.0). Version 1.2 has been extended with basic GIS functionality, and parts of the code have been restructured.
