Claims14
A breathing apparatus comprising:
- a wearable backplate comprising:
- a longitudinally extending frame configured to be supported on a user's back, the frame comprising a cylinder support for supporting a breathing gas cylinder, and having an upper end configured to be arranged proximate the user's shoulders in use and a lower end configured to be arranged proximate the user's lower back or waist in use;
- first and second lighting modules on opposing lateral sides of the cylinder support, the lighting modules comprising a vertical lighting array configured to project light longitudinally towards the upper end of the backplate;
- wherein the vertical lighting array comprises a light director for directing light from a lighting element longitudinally towards the upper end of the backplate;
- and
- a controller configured to:
- receive data indicative of a status of the breathing apparatus and/or the user;
- determine a status condition of the breathing apparatus and/or the user;
- and
- control the lighting modules to illuminate in:
- a first lighting pattern if the determined status condition is a normal status condition;
- and
- a second lighting pattern if the determined status condition is an alert status condition.
