There is a sign on the left side of the stairs that reads "Riser Zone 4". The stairs appear to be new and well-maintained, with no visible signs or markings. The floor is made of concrete and there are concrete pillars supporting the stairs. The ceiling is high and has recessed lighting. The overall appearance of the space is modern and industrial.
