Two individuals in gray clothing and face coverings are tending a large fire within a brick structure. The person on the left uses a long tool to interact with the fire, while the person on the right pours something from a small metal container into the flames. The fire is substantial and produces a lot of smoke. Around the fire are stacks of bricks and various metal containers. A large bag sits on the floor next to the person pouring liquid into the fire. The scene appears to be an industrial or workshop setting.
