The image shows a close-up of a metal door with a warning sign on it. The sign is blue and white with the words "WARNING: No trespassing, private property, Columbia Gas, Inc." written in bold black letters. Below the warning sign, there is a yellow caution sign with black text that reads "CAUTION: No smoking, no smoking, or open light." The door is attached to a brick wall with a black latch. The brick wall appears to be old and weathered, with some cracks and chips visible.
