Abstract
A panel, preferably a ceiling panel, for an arc resistant cabinet defines at least one flap dimensioned and configured to bend outward in response to excessive pressure within the cabinet. The flap is bent into a position wherein it will direct high temperature, expanding gases exiting the cabinet away from areas where personnel are likely to be located. The panel also includes a frame below the flap, thereby permitting the entire panel, including the flap, to support the weight of people working on top of the cabinet.
