Which statement about checking hoselines prior to ignition is FALSE?

The statement that each hoseline should be checked individually is false in the context of verifying flow pressures before ignition. When preparing for live fire training, it is crucial to flow all hoselines simultaneously. This approach ensures that you can accurately assess the overall water delivery system, including how the flow pressures interact with one another. Checking hoselines one at a time might not provide a complete picture of the system's performance, as some hoses might experience different pressures that could lead to inadequate water supply when coupled with others during an emergency situation or training evolution.

The importance of verifying all exposure, attack, and backup lines is that it ensures readiness and safety. Flowing all hoselines together allows instructors and firefighters to identify any potential issues with the equipment or system before live fire operations commence, allowing for timely corrections.
