The present invention provides systems and methods for producing a shield for protecting an area from a pressure blast. The shield, which attenuates the pressure blast, can be used with tall, mobile, and underwater structures, including structures in densely populated areas. One system includes a source for providing an attenuation material, a delivery system that delivers the attenuation material to nozzles, and at least one valve device to control the delivery. A detector is configured to actuate the valve device to an open position in response to a perceived blast threat so that the delivery system delivers the attenuation material to form the shield proximate to a periphery of the protected area.
