CASE 4: Side Coiling without Egress

Vertical Opening Separation

These case studies deal with a condition wherein several floors are common to each other. The floors are inter-connected with an interior exit access or communicating stairways. Previous editions of the code addressed these stair features as non-egress stairs. The 2015 edition of the code defines exit access stairways as stairways with the exit access portion of the means of egress system. (202)
