A male construction worker is observed on the roof framing of a building in the city of Rafin Bauna, Nigeria. The individual, dressed in an orange cap, an orange reflective safety vest over a dark shirt, dark pants, and dark shoes, is crouched on a diagonal wooden rafter. He manipulates a horizontal wooden batten with his left hand while holding a hand tool in his right, indicating active installation or adjustment of the roof components. The comprehensive roof structure consists of an interconnected network of light-colored wooden rafters and battens. Beneath this framework, concrete block walls are visible, along with an open interior space featuring blue-tiled surfaces. The background shows a clear blue sky with scattered cirrus clouds. Distant buildings and an indistinct, hazy horizon are visible under bright daylight conditions.
