What is an important general rule to follow at doors and windows before forcing entry?

The principle of trying before prying emphasizes the importance of assessing the situation before using force to gain entry. This approach can highlight whether the door or window is already unlocked or can be opened with little effort, which saves time and minimizes potential damage to the property.

Additionally, it allows firefighters to evaluate conditions on the other side of the door or window, which could be vital for their safety and operations. Checking for an unlocked entry point can ensure a more efficient and safer response in emergency situations.
