In my mall project, the staircase enclosure is 2 hr. fire rated as per NFPA - 101. The staircase is constructed in well load "I" section structures from 10th level of multiple basement to ground level and still extended to retail level 11. 

Is there any fire code to have a relevant respective fire rating for "I" section of staircase structure and the steps on it!
