Abstract
An auxiliary device for a face mask is arranged to convey clean air to the breathing area of the worker, the device comprising a space which communicates with tubes, hoses or the like carrying air, and a wall surrounding the space and with openings or the like for conveying clean air to the breathing area. The space together with its walls forms a structure 5 in the form of a loose collar, and the device comprises members for securing the space below the worker's face, and the openings or the like are arranged at that point on the wall which is directed towards the worker's face when the space 1 is secured in position. The space and the walls surrounding it form a closed bag 5 or the like which is to be secured below the worker's face and whose walls are made of flexible material. <IMAGE>
