There are three people in the image. The person on the left is wearing a white shirt and appears to be standing near a machine with a yellow hose attached. The person in the middle is dressed in a dark-colored jacket and is holding a white object, possibly a piece of equipment or a control panel. The person on the right is wearing a blue shirt and is holding a white device with a yellow cord. All three individuals seem to be engaged in some form of work or maintenance activity.
