Shelter and ventilator equipment analyses were performed to determine the best ventilator kits for the 138,000 below-grade fallout shelters identified during the second phase of the National Fallout Shelter Survey NFSS. The basis for the study was a random sampling of 160 facilities. Sketches of these shelters were analyzed for basic characteristics that define the ventilation requirements, and by matching the performance of over 600 fans to the shelter requirements, the best seven kits were chosen based on a least-cost ventilation system. The final selection of kits to be stocked depends on considerations other than engineering, primarily human factors.
