Appendix A Illustrations and Tables (numerous items). Sections simulating four types of frame building structures were exposed to TUMBLER Shots 3 and 4. The four types wee: (1) cubicle room with furnishing, (2) wall-corner, (3) Cornice-corner, and (4) roof. Sections 2 and 3 were exposed with and without a fine flash fuel. Douglas-fir springwood was charred at least slightly out to about 13,000 feel (radiant exposure 4.0 cal/cm2) by Shot 3 and about 10,000 feet (radiant exposure 5.1 ca./cm2) by Shot 4. Sustained burning, either as glowing or flaming, took place only in fine fuels. It was concluded that the flash of radiant energy from an atomic explosion will set sustained primary fire in fine fuel, but in general not in more massive fuels such as lumber and plywood. It was recommended that field study of primary fires on building structures be confined to find fuels to ascertain the conditions under which they become ignited to self-sustaining fire and to such other shapes and materials as may be shown by laboratory experimentation to be a possible fuel for sustained primary fire. Operation Tumbler–Snapper was a series of atomic tests conducted by the United States in early 1952 at the Nevada Test Site. The Tumbler–Snapper series of tests followed Operation Buster–Jangle, and preceded Operation Ivy. The Tumbler phase, sponsored by the Atomic Energy Commission consisted of three airdrops which were intended to help explain discrepancies in the actual and estimated blast shock wave damage noted on previous detonations, and to establish more accurately the optimum height of burst. The Snapper phase, sponsored by the Department of Defense consisted of one airdrop and four tower shots intended to test various new weapons developments. Operation Tumbler consisted of three air bursts conducted to gather detailed information about blast effects, the fourth test was also an airburst and technically part of both Tumbler and Snapper. Condition: Good.
