Abstract : A study was made of the optimum location for blast protection of generators in pits and shelters. The factors considered were cost, blast overpressure, dynamic pressure, operational dependability, and cooling air requirements. Ground shock and radioactivity were not considered. Representative locations and arrangements studied were: (1) open pit, (2) pit covered with grating, (3) pit covered with filter, (4) underground shelter, (5) room adjoining shelter, (6) separate underground compartment, and (7) building above ground. As it could be expected underground locations give the most protection but are the most expensive. Least expensive is the open pit, which gives the lease protection. If the above-ground building can withstand the overpressure, it is as effective a location for generators as the underground compartment. Heat, noise, vibration and exhaust create problems when generators are located within shelters. Open pits with gratings provide economical protection from dynamic pressure. A filter cover using compressible cylinders should provide sufficient protection at moderate cost, but needs further development.
