Abstract

See full text

The breathing protection equipment includes a mask having an inflatable harness and a demand regulator with three operating modes which are manually selectable. The operating mode is indicated to the wearer of the mask by a repeater. The repeater has a mode sensor carried by the mask and a mode indicator located in the field of view of the wearer and driven by the mode sensor. The mode sensor may detect the position of the switch actuated by the user for changing the mode. The mode indicator may be a display on a mask storage box or on the mask.
