What is the maximum PO2 that can be used by BSAC rebreather divers for open circuit bailout?
1.4 bars. This is the same as recommended for open circuit Nitrox. The bailout plan of a mixed gas rebreather diver will possibly involve the use of multiple bailout gases. Choice of the bailout gases should be carefully planned in line with the diver’s qualifications and not exceed the PO2 of 1.4 bar.
