Japan Explosive Society

Technical committee on explosion safety

Chair, Tei Saburi

Outline and activities

The Explosion Safety Technical Committee conducts activities with the aim of advancing our understanding and expertise in the performance and testing methods of energetic materials, such as explosives. We also focus on comprehending the phenomena related to explosions caused by these materials and developing measures for explosion mitigation and safety.

Our committee has assumed the responsibilities of the "Sensitivity Technical Committee" and the "Explosion Impact Technical Committee," which were active until 2005. Our scope encompasses everything from evaluating the sensitivity and explosive power of energetic materials to studying phenomena related to explosions, high-speed combustion, and impacts.

One specific issue involves the revision of the Japan Explosives Society standard (test method), inherited from the former Sensitivity Technical Committee. This standard has undergone revisions since its initial publication in 1983, with subsequent editions in 1985, 1988, and the Japan Explosives Society Standard (IV) (sensitivity test method) in 1995. We are currently reviewing various test methods in response to changing times and discussing the publication of the revised version with the aim of aligning it with international standards.

When an explosive detonation occurs, the resulting blast wave can cause significant harm to both individuals and structures, even at a distance. In addition to conducting studies on the safe management of explosives and improving handling methods, our committee is actively researching blast impact mitigation technology to minimize damage in the event of an unexpected explosion—an issue of great importance to our technical committee.

We are actively encouraging students and other young researchers to participate in our committee. We will foster discussions across various specialties and generations, create an environment conducive to collaborative research, and engage in activities aimed at identifying potential needs in the field of explosion safety and aligning them with the technological innovations of the next generation of researchers.
