There are three individuals in the image. They are wearing bright orange safety vests with reflective stripes, which are commonly used for visibility during firefighting operations. The vests are worn over dark clothing, suggesting they might be working in a cooler environment. One person is holding a fire extinguisher, while the other two appear to be engaged in some form of firefighting activity, possibly using hoses or other equipment. The third individual is partially obscured but seems to be involved in the same activity as the others.
