The photograph shows an over-the-shoulder shot of a man in high-visibility working on calibrating a fire extinguisher system mounted to the front-end arm lift attached to an open-cabin truck body. The system has yellow and red "60L" markings. The man is holding two canes with black wires coming out of them. The vehicle has white cloth coverings around it, set against a light grey background, creating a stark contrast that emphasizes the subject matter. --ar 72:49
