Before beginning any forcible entry, which simple rule should firefighters keep in mind?

The concept of "Try before you pry" emphasizes the importance of assessing a situation before applying force to a door or any other entry point. This principle encourages firefighters to verify if a door is locked and to check for the possibility of it being opened without the use of tools first. It is a crucial safety measure, as prying open a door without first attempting to turn the handle or checking its status can lead to unnecessary damage to property or injuries to firefighters due to unexpected conditions behind the door.

This approach also promotes efficiency in operations. If a door can be opened easily, it can save valuable time during rescue operations or firefighting efforts. Moreover, it reduces the risk of creating additional hazards inside a structure, such as worsening a fire situation if the door opens directly into a heavily involved area.

In comparison to the other options, while the other rules offer important considerations in firefighting practices, they either focus on specific tactics or broader philosophies rather than the immediate action of assessing entry points. The principle of trying before prying is highly relevant during forcible entry and can significantly impact the safety and effectiveness of emergency operations.
