The deceased was identified as Ranjan Kumar Sarangi of the district bomb disposal squad.
The district police had seized 53 crude bombs and 12 detonators from an abandoned hut in Gambhari village at the bank of Chilika Lake.
The seized explosive materials were shifted to Brahmagiri police station with help of the bomb disposal squad.
"However, one of the bombs went off despite keeping it inside water for several hours," Sahu said, adding that no one was arrested on charge of storing the explosive materials.
