What is a common tool used to assess the structural integrity during firefighting operations?

A pike pole is a common tool used to assess structural integrity during firefighting operations due to its practical applications in handling emergencies. This tool, typically a long pole with a sharp hook or point at one end, allows firefighters to probe and open up structures, especially ceilings and walls. By using a pike pole, firefighters can check for hidden fire, ascertain the condition of materials, and determine if a structure can support the weight of personnel and equipment.

The ability to physically manipulate materials in the environment is crucial while assessing the safety of a building under the stress of fire. It provides tactile feedback about the integrity of structural elements, such as if they are charred, weakened, or about to collapse. While other tools like thermometers or drones serve useful roles in assessing conditions or gathering data, they do not directly allow firefighters to interact with and assess the physical structure in the same direct manner as a pike pole.
