A proposed experimental program to evaluate ventilation system component responses to natural and man-caused pressure transients is described. Initial program emphasis is on tornado- and explosive-generated pressure loadings on filtration devices. A review of other investigations revealed that only standard high-efficiency particulate air (HEPA) filters have been considered for experimental analysis. The testing of new types of HEPA filters that will be capable of handling larger flow rates is proposed. Larger flow rates mean increased filter life with a subsequent reduction in the quantity of contaminated filters. Following these experiments it is proposed that shock pressure loadings on other ventilation system components such as duct work, blowers, and dampers be performed. Also, the effect of these components on shock wave characteristics will be determined. A conceptual shock tube design shows how the current tornado simulation apparatus can be modified to generate shock pressure pulses. Equipment to vary the magnitude and shape of the shock transient is also described.
