Abstract
An arc flash protective hood device. The protective hood is fitted with a passive blackbody radiation shield device formed with facing plates, each plate having a plurality of slots therethrough, the slots in one plate being in offset registration with the slots in the other plate, thereby creating a semi-tortuous path for fluid flow through the device. The semi-tortuous path for air flow is so formed to prevent arc-flash energy from passing through the shield device. Alternatively, the shield device may be a single, integral element, or each plate may be made in two or more segments. The blackbody radiation shield device may be mounted in an opening in a hood, and several such shield devices may be mounted in several openings in the hood.
