Document Type and Number:
Japanese Patent JP2003516831
Kind Code:
A
Abstract:
A respirator system ( 10; 100 ) for a worker in an environment with hazardous airborne contaminants comprises a respirator ( 12, 112 ), a helmet ( 14, 114 ), a camera ( 40, 140 ), and a gas sample analyser ( 16, 116 ) capable of analysing samples of gas from within the respirator and in the immediate area near the user. An RF emitter ( 20, 120 ) sends a signal to a remote receiver ( 24, 124 ). The emitted signal is a real time view through the camera ( 40, 140 ) and overlaid on that is a graphical representation of the protection factor being achieved by the respirator. The system ( 100 ) may also have a data storage device ( 162, 170 ) to store data such as how protection factor varies with time and may have a position sensor ( 160 ). The provision of the position sensor ( 160 ) allows a map of contamination levels with position to be built up as a user moves around a site.
