Abstract: The invention is a breathing hood assembly for protecting a person from a fire and toxic gases produced therefrom. The invention comprises a fire resistant hood of a sufficient size so as to fit over the person's head. The hood has a neck portion including a drawstring or elastic for sealing the hood to the neck of the person. The interior surface of the neck portion is lined with a silica gel and barium oxide impregnated cloth. A transparent window is mounted to the hood extending about the periphery thereof. A filter is mounted to the hood which extends about the periphery thereof and is in communication with the interior of the hood. The filter includes an inner sodium bisulfate impregnated cloth layer and an outer fire resistant cloth cover. The outer fire resistant cloth cover is joined at its edges to the edges of the inner cloth layer forming a donut shaped cavity. A donut shaped cloth bag impregnated with silica gel and barium hydroxide is mounted within the cavity.
