Vented safety cabinet with thermally-actuated damper
A safety cabinet includes an enclosure and at least one door to selectively seal the enclosure. The safety cabinet can be used to store, for example, flammable liquids, flammable waste, corrosives, pesticides, or combustible waste. The safety cabinet incorporates a thermally-actuated damper that includes a body, a valve plate, and a pivot assembly. The valve plate is disposed within the passage of the body such that the valve plate is movable between an open position and a closed position. The pivot assembly includes a biasing system adapted to bias the valve plate to the closed position and a fusible link interconnected between the body and the biasing system to constrain the valve plate from moving from the open position to the closed position. The fusible link is configured to melt at a predetermined temperature to thereby allow the biasing system to move the valve plate to the closed position.
