Explore the vital role of hand crews in wildland firefighting. Learn how these teams use strategy and hand tools to build firelines and contain massive wildfires.

Even with all our technology—airplanes, satellites, infrared cameras—the final line of defense is still a group of 20 people with hand tools. By stripping fuel away to mineral soil, we are using the most direct and effective method possible to stop a fire.
How firefighters use hand crews and fire lines to fight wildfires, including the physical tools, techniques for cutting line, and safety protocols.

A fireline is a critical strip of ground that has been stripped entirely of all flammable material, right down to the mineral soil. Similar to a hiking trail, its primary purpose is to create a gap that a wildfire simply cannot jump. By removing everything that can burn, hand crews create a perimeter that stops the fire's progress, which is a fundamental strategy in fire containment.
While airtankers are vital for cooling flames with red retardant, they do not actually put the fire out; they only slow it down. To truly contain a wildfire, hand crews of 18 to 20 firefighters must hike into areas that bulldozers and vehicles cannot reach. These crews perform the manual labor required to carve out a perimeter on the dirt, making them the backbone of wildland firefighting.
The construction of a fireline involves high-level strategy and specific physical dimensions to be effective against a wildfire. A general rule used by these crews is to clear a path that is twice as wide as the nearby brush is tall. This human-led effort ensures that the elemental force of the fire is met with a sufficient gap of mineral soil, preventing the flames from spreading further.
