摘要
In a protective combination wearable by a firefighter or by an emergency worker, a face mask has a face-conformable gasket defining an outwardly opening trough. Further, a protective garment has a hood, which has a peripheral edge and which defines a tubular hem along the peripheral edge. Moreover, an inflatable tube, which extends through the tubular hem, is adapted to form a seal between the face-conformable gasket and the peripheral edge of the hood, when inflated so as to press the tubular hem along the peripheral edge of the hood into the outwardly opening trough, whereby to provide a seal between the face mask and the hood.
