What is the primary function of a set of irons in firefighting?

The primary function of a set of irons in firefighting is to forcibly enter structures during emergencies. This set typically consists of tools like a halligan bar and a flathead axe, which are essential for prying open doors, breaking through walls, or other barriers that may obstruct access. In emergency situations, where time is critical, having the right tools to gain entry quickly can be a matter of life and death, both for victims trapped inside and for the firefighters who are working to rescue them. The design of these tools allows firefighters to leverage their strength effectively and to operate in very demanding conditions, ensuring that they can access areas that need immediate attention.

Other options may seem relevant but do not align with the primary purpose of this equipment. For example, securing a fire engine in place, cutting through metal equipment, or holding hoses in position are tasks addressed by different specialized tools and methods in the firefighting toolkit.
