Abstract
A hood, particularly for an emergency escape breathing apparatus and having a box-like appearance, comprises generally planar front and rear panels left and right side panel and a top panel. The panels are made from flexible material, but the box-like shape is maintained by stiffening the front and rear panels by stiffening means. The front panel is formed with a transparent visor. Breathable gas is supplied to the hood via a valve attached to a fitting on the front panel.
