There are three people visible in the image. They appear to be working on a construction site, as indicated by the scaffolding and the materials being used. The person on the left is wearing a yellow safety jacket and appears to be using a tool, possibly a drill or hammer. The person in the middle is also wearing a yellow safety jacket and seems to be holding a piece of wood or a similar material. The person on the right is wearing a blue safety jacket and appears to be holding a piece of equipment, possibly a crane or lifting device.
