Traditionally, methods used for inputting gasses to Class I Laser Enclosures or exhausting gases from Class I Laser Enclosures presented problems for designers to ensure fail-safe interlock character- istics. Switches can fail and hoses can be replaced on input/output ports with the interlock feature defeated. This presents an opportunity for acciden- tal exposure to laser radiation hazards. The laser emission baffle provides a non-defeatable solution to this problem. The baffle is designed to be left in place even during maintenance or repair procedures. The baffle, detailed in the attached drawings Figures 1 and 2, allows gases to enter or exit from the enclosure without removal. If an input/output hose was not attached to the port, this device prevents any Laser energy from escaping and causing a hazard.
