Abstract:
A ventilation device for use in protective hoods. The ventilation device is 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 air flow through the ventilation device. Alternatively, the ventilation device may be a single, integral element, or each plate may be made in two or more segments. The ventilation device may be mounted in an opening in a hood, and several ventilation devices may be mounted in several openings in the hood.

Claim (Index 21):
A device for use with a safety face shield assembly, the device comprising:\n a hood configured to cover at least the head of a wearer and incorporating the safety face shield, the hood and safety face shield being formed of materials that protect the wearer from arc-flashes, said hood having an opening in at least one location; a ventilation device mounted in said opening, said ventilation device having a periphery, said hood being secured to the periphery of said ventilation device, said ventilation device comprising:\n a first plate having a first plurality of slots therethrough; and \n a baffle plate mounted to and at least partially spaced from said first plate; \n said first and baffle plates being arranged in face-to-face relationship so that there is no direct fluid flow route through the slots in said first plate and past said baffle plate, thereby providing a semi-tortuous path for ventilation between internal and external sides of said hood, said ventilation device being formed of materials that block arc-flashes, the semi-tortuous path thereby protecting the wearer from an arc-flash.
