What is the number of exits required from a space based on?
the occupancy type
the occupancy load of the space itself
limitations on the travel distance length
What do you multiply to get the minimum exit width in stairways?
0.3 per occupant (x) occupant load

What addresses the resistance to the spread of fire within a building?
Fire separating
4 main goals of compartmentation:
contain a fire, limit the spread of fire, allow occupants to escape the building, protect unaffected parts of the building
How is structural compartmentation achieved?
door assembly ratings, floor-ceiling assemblies, fire-rated walls, fire separations

Fire partition
Where are fire partitions commonly used?
corridor walls, elevator lobby, walls separating dwelling units/guest rooms, walls separating tenants in shopping malls
What type of wall can be a vertical or horizontal fire-resistance-rated structure designed to confine fire and allow for safe passage? (usually extend from floor to floor or floor to roof)
Fire barrier
Where are fire barriers commonly used?
Enclose stairways, exit passageways, horizontal exits, and incidental use areas / Separate different occupancies in mixed-use occupancies / Separate single occupancies into different fire areas
What type of wall is an exterior wall that extends continuously from the base of the building to the roof with 3-4 hr rating?
Fire wall
What are 2 characteristics of fire doors?
