| Description | PLUMBBOB - 1957 - NEVADA TEST SITE -- A recent atomic test during Operation Plumbbob tested the second of two sets of five doors, sponsored by the Federal Civil Defense Administration. Pressure waves at low ranges slightly blackened the paint finish on the two steel doors. The three wooden doors were partially charred. All of the doors, the frames and the extra heavy steel commercial hardware stood up under the test. Left to right, the doors were made of (1) solid plywood, (2) wood planking, (3) cellular steel formed of sheet Q-panels, (4) hollow plywood, and (5) steel plate. Two anti-blast valves -- 16 inch diameter (left) and 24-inch diameter -- are mounted on the wall. Automatically activated by the pressure wave, the valves operated satisfactorily. | |||
