Applications of Suppressive Shielding in Hazardous Operation Protection.

摘要

A new kind of protective barricade is being developed by Edgewood Arsenal for use in protecting equipment and personnel that are performing hazardous operations during the manufacturing of munitions in army ammunition plants. This protective structure i.e.,suppressive shield,provides protection from the dangerous effects of an explosive detonation. The suppressive shield consists of a series of vented panels in a framework. The vented panels are fabricated from a combination of perforated plates,spaced angle irons,louvred plates and/or wire screening;the specific arrangement depends on the hazard to be suppressed. Suppressive shields are designed to attenuate the explosive blast pressure and fireball and prevent any fragments from escaping the structure.
