Institute of Makers of Explosives Safety Analysis for Risk

IMESAFR is a probabilistic risk assessment tool used to calculate risk to personnel from explosives facilities. This tool is a supplement to the longstanding American Table of Distances (ATD). Whereas, ATD provides a level of safety based on explosives quantity and distance, IMESAFR determines a level of safety based upon risk. In addition to explosives quantity and distance, IMESAFR uses the donor structure, the activity at the donor, and the structure of the exposed sites to determine the level of safety.…more


Range Test Scheduling System

RTSS is a fully web-based range scheduling tool that allows users to request time and support organization resources in order to conduct tests on ranges. All users have visibility of range schedules weeks or months in advance. View the RTSS demo here.


Safety Assessment For Explosives Risk

SAFER performs quantitative risk analysis to determine risk to people from a potential explosion site by conducting a sequential calculation of probability of event, explosives effects, and personnel exposure. SAFER can be used to assess the risks to people in inhabited building distance, public traffic route, and intraline distance scenarios…more


Ground Risk Model

GRM simulates worst case trim turns from a nominal trajectory followed by flight termination. Modeled turns are based on the Range Safety Officer response time and maximum vehicle capability. Debris fragments are propagated to impact or aircraft altitudes and hazard footprints are developed for each time increment. Casualty expectation is computed for each population center/asset within the hazard area and total mission risks from malfunctions are determined.


Analysis of Death and Injuries Resulting from Explosions

DIRE uses state-of-the-art consequence modeling to determine the optimal location of explosive facilities in order to ensure minimal loss of life and structural damage should an accident occur. With the ability to input variable factors such as explosives distance and quantity, on a variety of different structures, DIRE provides a user-friendly tool for finding valuable hazard information…more
