A driptorch is a special kind of tool that firefighters use to start controlled fires. It looks like a long stick with a container attached to the end. The container holds a mixture of diesel fuel and gasoline.
The firefighter holds the driptorch and walks along the area where they want to start the fire. They use a small flame to light the fuel mixture in the container. The mixture drips out slowly, creating a trail of fire that burns the ground vegetation without spreading out of control.
Think of it like a magic wand that creates a controlled fire trail, to help manage the burning of land during a wildfire. It's like painting a line of fire with the driptorch. Firefighters use driptorch to help burn off excess vegetation or remove dry brush so that future wildfires won't spread as easily.
