Abstract
A respirator system () for a worker in an environment with hazardous airborne contaminants comprises a respirator (), a helmet (), a camera (), and a gas sample analyser () capable of analysing samples of gas from within the respirator and in the immediate area near the user. An RF emitter () sends a signal to a remote receiver (). The emitted signal is a real time view through the camera () and overlaid on that is a graphical representation of the protection factor being achieved by the respirator. The system () may also have a data storage device () to store data such as how protection factor varies with time and may have a position sensor (). The provision of the position sensor () allows a map of contamination levels with position to be built up as a user moves around a site.
