Research and Development Establishment (Engineers), R&DE(E), Pune, has successfully
developed and conducted a series of trials on the Blast Containment Enclosure. It is an indigenous, firstof-its-kind, one time use, cost-effective containment
enclosure to contain the blast effects of a 6 kg improvised explosive device (IED) made with 4 kg TNT and 2 kg shrapnel. Six enclosures have been tested. The trials met all
the requirements to withstand the explosive energy and shrapnel.


A novel sandwich construction is employed to dissipate blast energy through plastic energy absorption. Pressure at 8 m from the enclosure was measured to be within human sustainable limit. Weight of one enclosure is around 300 kg and its
estimated cost is approximately Rs 1.5 lakhs. The trials were witnessed by Principal,
Institute of Improvised Explosive Device Management, CRPF, Pune.
