An emergency exit sign is affixed to a light gray wall

An emergency exit sign is affixed to a light gray wall. The sign is square with a green background and a white pictogram. The pictogram depicts a stylized person running down a set of stairs, indicated by three descending horizontal bars. To the right of the stairs, a white arrow points diagonally downwards and to the right, indicating the direction of the exit. The sign is located on a wall in Rooppur, Bangladesh, likely within a building associated with the Rooppur Nuclear Power Plant. The wall appears to be painted or finished with a slightly textured surface.
