Which tool is commonly used to open a ceiling during firefighting operations?

The pike pole is a tool specifically designed for use in firefighting operations, particularly for opening up ceilings and walls to investigate hidden fire or to ventilate a structure. Its long, slender pole allows firefighters to reach high areas without the need for a ladder, making it efficient for accessing ceilings where fire may be smoldering or hiding. The sharp end, often featuring a pointed tip or hook, can puncture through ceiling materials, while the other end can be used to pull down debris, providing better access to check for fire extension.

In contrast, while the pick-head axe is versatile for various cutting duties and the Kelly tool and Rex tool have functions mainly focused on prying and pulling, they are not specifically designed for opening ceilings to the extent that a pike pole is. Each of these tools has its own unique purpose in firefighting, but when it comes to managing ceilings, the pike pole stands out as the most effective and commonly used tool.
