Closed circuit BA's have there uses and they are good at them! But they are not ideal for quick entry limited duration jobs.
Look at the initial $$$ to buy them, then maintain them, testing and recommissioning after use!
Use them a few times and you will be turned off them quick smart :lol:
Just a few comments on the easier breathing... even with the sets that have inbuilt ice canister after a few hours of work the air is really hot to breath!
Faster deployment hmmm i would disagree, 3 checks with OCBA, to be confident with a CCBA over 10 checks would be good!
How does Open circuit BA increase CO2 buildup. Exhaled air is spent to atmosphere, so you keep breathing a normal atmosphere of air with each inhaled breath of air.
If you would like me to provide more detail re OC /CC BA let me know!
