A piercing nozzle is particularly effective for tackling ground fires, which are typically found in environments with deep-seated fires such as those involving combustible materials in the soil or below the surface, like mulch or leaf litter. The design of a piercing nozzle allows firefighters to penetrate barriers like roofs, walls, or earth, delivering water or firefighting foam directly to the seat of the fire. This capability is essential when traditional methods are insufficient or when the fire is not immediately accessible.

In contrast, other types of fires, such as field fires, highrise fires, and vehicle fires, have different requirements for suppression. Field fires generally require wide-area firefighting techniques due to their size and nature, which may not involve the need for direct penetration. Highrise fires often necessitate specialized equipment and techniques to navigate the complexities of multi-story buildings. Vehicle fires typically require quick and direct firefighting approaches, often using standard nozzles designed for rapid application rather than the low flow and penetration capabilities of a piercing nozzle. Thus, the application of a piercing nozzle is primarily suited for ground fires, where penetrating barriers to deliver water directly to the fire is essential for effective control.
