IMESAFR Learn More
Institute of Makers of Explosives Safety Analysis for Risk (IMESAFR) is a quantitative risk assessment (QRA) tool used to calculate risk to personnel from commercial explosives facilities and operations. IMESAFR, uses information about the donor structure, about the explosives type and activity at the donor, and about the exposed site structure to calculate risk and is an effective supplement to the longstanding American Table of Distances.
IME works in conjunction with A-P-T Research, Inc. (APT), an engineering services company in Huntsville, Alabama to develop and maintain IMESAFR.
IMESAFR v2.1 -- Expected Release Spring 2018IMESAFR TRAINING INFORMATION
APT Research is planning IMESAFR v2.1 Training - (April 11-13, 2018) in Ottawa, ONT, Canada in conjunction with the 18th International Conference of Chief Inspectors of Explosives. An Upgrade 2.0 to 2.1 (Improvements) class will be offered to those who have completed IMESAFR v2.0 training and do not wish to take the full v2.1 course.
Training for the recently released AN Module will also be offered to those who have completed IMESAFR 2.0 or 2.1 training. Both courses will be 1/2 day courses to be held in Ottawa (non-concurrently) on April 18, 2018.
If you have questions, please contact Mary Robinson, IMESAFR Training Coordinator (mrobinson@apt-research.com). Click here to download the registration form for Ottawa Training. Click here to view IMESAFR Training brochure.
IMESAFR software and training is made available through APT. Because of our commitment to explosives safety and due to the complexity of IMESAFR, it is IME's policy, before issuing a permanent license to use IMESAFR, to require training in QRA concepts and the proper use of the software tool. For more information about IMESAFR software and training, use the following link to access the IMESAFR Informational Brochure.
