EE pulled disconnect handle to "off" position & installed lock on disconnect handle that supplied power to loadout bin. He went to splice wires in splice box. When attempting to open cover on splice box it blew in front of him, resulting in 2nd deg flash burns to both hands. He was going to attempt to test for current at splice box but didn't get opportunity to do so.
