This report represents the results of an experiment to verify the adequacy of a supplement to ER 1190-1-2 and TR 20 Volume 3, the Technical Manual for Ventilation Analysis Procedure. The purpose of the experiment was to predict the rate of induced air flow through a fallout shelter. The only applied force in the shelter is the sensible heat given off by its occupants. Induced air flows through three model chambers containing resistance heaters that simulated body heat air-flow speeds from 10 to 30 fpm were measured using thermistors. After demonstrating that the model test results would be similar to the flows expected in larger shelters of a similar geometry, test runs involving one and two chamber wall cutouts were conducted.
