Which tool is primarily used for breaking through doors during forcible entry?

The Halligan tool is primarily designed for forcible entry and is favored among firefighters for breaking through doors. This versatile tool typically features a pick, a fork, and a blade, allowing firefighters to effectively pry open doors, apply leverage, and perform various forcible entry tasks. The design enables quick and efficient penetration into a structure, making it an essential tool for rescue operations and fire suppression.

Other tools like the flathead axe, hydraulic cutter, and sledgehammer have specific applications but are not as specialized for the quick entry that the Halligan tool provides. The flathead axe, while useful for chopping and breaking, lacks the prying capabilities crucial for effectively opening doors. The hydraulic cutter is primarily utilized for cutting through metal and is not suitable for wooden or standard doors. The sledgehammer, while effective for applied force, is less precise and requires more physical effort and time compared to the efficiency of the Halligan tool in emergency situations.
