What is a limitation associated with Compressed Air Foam Systems (CAFS)?

Hose reaction being erratic is a notable limitation associated with Compressed Air Foam Systems (CAFS). When CAFS is utilized, the foam is created by mixing air, water, and foam concentrate, which can lead to variations in the flow and pressure depending on the system's setup, hose length, and nozzle type. This can make it challenging for firefighters to manage the hose effectively, as the reaction can vary during operations, impacting their ability to apply the foam consistently and predictably in fire situations.

While increased cost of operation, limited range of operation, and the ability to use water as an extinguishing agent may present challenges or considerations with CAFS, they do not pertain to the immediate, operational challenges posed by hose reaction.
