John Kermode said:Rebreathers in BSAC Training
Nick Kay contacted me to ask for an opinion about the use of rebreathers in BSAC training. Having consulted with my colleagues on the National Diving Committee I hope that the following helps to clarify the position.
BSAC advice and guidance is regularly reviewed and updated and so the BSAC website provides the most up-to- date information:
The page: Rebreathers in BSAC Training - BSAC
provides a comprehensive matrix of when a rebreather can be used in diver training and includes details of suitable buddy pairing for non training dives for qualified divers. (this supercedes the published information in 'Safe Diving').
In answer to a supplementary question from Nick: The current view of the NDC is that it is not necessary for the instructor to be a rebreather instructor if they are instructing/ assessing an open circuit candidate within the above matrix and teaching generic diving rather than rebreather specific skills. They do need to be rebreather qualified , and have gained adequate experience (an instructor cannot afford to be distracted by his own learning needs whilst responsible for student training), on the unit they use and they need to be at least an OWI. The guidance and suitability of such a situation will continue to be reviewed.
The same principle applies even if the student is also a rebreather user. The student has already been taught to use the unit on a SCR or CCR on a basic ‘air diluent’ course or mixed gas (tri-mix/heliox) diluent courses or by a rebreather qualified instructor.
The next question was with respect to particular rebreather units.
Our position is that, for branch diving, CE approved units may used as may those units which have a training programme recognised by BSAC.
The web page: Recognised Rebreather Training Agencies & Courses. - BSAC
provides current guidance as to the recognised training programmes and the respective units.
The NDC have taken the view that, anyone teaching on an Instructor Training Scheme (ITS) event must use a CE marked unit. This reflects the guidance to which BSAC Centres and those operating commercially must adhere.
I hope that this answers the questions.
