The image shows a closed metal door in a corner of a concrete wall. The door appears to be made of corrugated metal and has vertical slats on it. On the right side of the door, there is a metal box with a handle and a hose attached to it. The box is rectangular in shape and has a latch on the top. The wall behind the door is also made of concrete and is peeling off in some areas. The ceiling is visible at the top of the image.
