Inside a dimly lit space, an individual uses a yellow brush to clean a surface

Inside a dimly lit space, an individual uses a yellow brush to clean a surface. The scene is back-lit by a bright light source, casting strong shadows. The surrounding environment contains what appears to be machinery or equipment, partially obscured by the darkness and a vertical support column. The person's arm is visible, clad in a light-colored shirt, as they manipulate the brush across the surface.
