    Abstract: An explosion suppressing vent for an electrical fixture which includes continuous flame-arresting channel of air space passing through the fixture wall and connecting air-space within the fixture with exterior air. Electrical fixtures partially enclosed by glass, or other relatively fragile membranes, benefit greatly from the invention since, through its use, maximum internal pressures during combustion of enclosed potentially explosive gas mixture is suprisingly low.
