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 1):
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 second plate having a second plurality of slots therethrough; \n said first and second plates being arranged in face-to-face relationship with said slots in said first and second plates being in offset registration so that there is no direct fluid flow route through the slots in said front and back plates, 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 external arc-flash.
