A fire truck with an extended ladder is spraying water from a bucket at the top, where a firefighter in a red helmet is visible. On the ground, a large, red and white foam cannon machine, mounted on tracks, is also spraying a massive amount of water. Several firefighters in dark blue uniforms and orange helmets are managing hoses connected to the foam cannon.
