When advancing an uncharged hose up a ladder, which statement is NOT true?

When advancing an uncharged hose up a ladder, the operation of a deck gun at a specific pressure, such as 80 psi, is not relevant to the task at hand. The primary focus when advancing an uncharged hose involves ensuring safety and stability, which includes securing the hose and ensuring the ladder is stable. Wearing full personal protective equipment (PPE) is also crucial for the firefighter's safety, particularly when engaging in physically demanding operations like climbing ladders. Therefore, stating that the deck gun operates at a certain psi does not accurately pertain to the procedure of advancing the hose up the ladder, making that statement not true in this context.
