Abstract (en)
[origin: US4771771A] Gas masks each with a protective hood according to the invention are used as rescue equipment, e.g. escape equipment. For this purpose, they must be available when needed in a fail-safe condition and then untrained persons must be able to apply and use them. The gas mask has in its protective hood portion a breathing attachment in form of a half mask. On the outside, the breathing attachment supports a plug-in frame which is open at opposite sides or ends and accommodates a breathing filter inserted therein through one of the open ends or sides. Respiration takes place through the inlet walls of the frame and the filter. The used-up breathing filter is replaced by inserting a replacement filter. The simple insertion or replacement of the breathing filter makes training of untrained persons possible by using training filters.
