What comprises the "irons" used in firefighting?

The term "irons" in firefighting refers specifically to a combination of tools that are essential for forcible entry and ventilation during emergency operations. This set of tools typically includes a flathead axe and a Halligan tool, which are designed for breaking through doors, walls, or other obstacles to gain access to a building or to allow smoke and heat to escape.

The flathead axe is useful for chopping and prying, while the Halligan tool, which combines a pike, a fork, and a blade, offers versatility in both prying open doors and breaking through barriers. Together, they are effective for quickly and efficiently gaining entry in potentially life-saving situations, making them a standard part of a firefighter's equipment.

The other tool combinations listed, such as chainsaws or ladders and hoses, are critical to firefighting operations but do not comprise the "irons." Chainsaws are primarily used for cutting through materials like wood, while ladders are essential for reaching heights and hoses are fundamental for delivering water. These tools serve different functions and are important in their own rights, but they do not have the same specific application as the "irons."
