@coachpriyaiyer In the workshop Part 4 Question2 calculating stair widths…we had (405 occupancy x .02) / 3 stairs = 27" and round up to 44" Min. No one mentioned that in the case that one stair is blocked in a fire, the other 2 must allow half the total load each, right? So, the minimum width of each stair would be 40.5". 44" is still the correct answer but am I correct in that logic? Same for Unsprinkled, except .03 multiplier?  
Thank you,
