ANDI started CCR training back around '92 or so.. It was not mixed gas CCR training.. but that excercise was also in all the mixed gas classes.. I do not know exactly when it was removed.. I remember moving it out of the instructor procedures (after discussions with several of the CCR ITS of the time) sometime early 2000s - probably around 2001 is my best guess as that time we started getting instructors in much more remote areas.. AGAIN this excercise was done on an OC gas not the loop.
thanks for the reply ,
