1018.4 Dead Ends: Where more than one exit or exit access doorway is required, the exit access shall be arranged such that there are no dead ends in corridors more than 20 feet (6096 mm) in length.

1004.6 Mezzanine Levels: The occupant load of a mezzanine lever with egress onto a room or area below shall be added to that room or area's occupant load, and the capacity of the exits shall be designed for the total occupant load thus established.
Greetings Jillian,
ReplyDeleteFor code 1018.4, the plan is quite unclear with were the exits are located. The approach is the correct one with drawing a floor plan but this floor plan is missing the main information needed to best represent the code. What the code says is that you are not permitted to have a corridor, that is longer than 20 feet in length, dead end (have only one entry/exit point). The space you are showing in the floor plan appears to be residential which can be misleading with this code because most often this code will apply to commercial spaces. Maybe think of this hypothetical space as an office building. Show that corridors that are greater than 20'-0" in length must have 2 exits and that a corridor less than 20'-0" can have a dead end.
For code 1004.6, the use of a perspective nicely represents what a mezzanine is but the inclusion of the occupancy for the mezzanine in the overall room occupancy calculation is missed. Somehow you will need to create a symbol that represents adding the two occupancy numbers together (mezzanine + main floor) to equal the total occupancy number listed for the room.
