The SCBA is a crucial part of the firefighters PPE. Indiana Smoke Divers believe that one should be prepared physically and mentally to wear the SCBA for long periods of time, in all types of environments, in a constant state of readiness. You cannot expect to  efficiently conduct fireground operations such as search and rescue, attack, ventilation, and salvage and overhaul without wearing and using your breathing apparatus. There is a high value placed on respiratory protection in the Smoke Diver program.  That is, protecting the respiratory tract of an individual through the proper and consistent use of the SCBA, the concern being both immediate and long term protection.
