There are five people visible in the image. They are wearing orange safety vests with the letters "NHA" on them. The vests are worn by individuals who appear to be part of an emergency response team, possibly firefighters or rescue workers. One person is holding what looks like a fire extinguisher. The individuals are standing close together, suggesting they are working together in a coordinated effort. The overall scene appears to be indoors, given the lighting and the presence of the vest.
