Being in a position to be able to use both CCBA & SCBA regularly, a CCBA will never be suitable for your standard fire service. Reasons - cost of individual units, unit testing time's, replacement component price and practicality of storage. Also after 2 hours in a CCBA the o2 you are breathing becomes that hot it becomes very unpleasant.
