24
Q

Occupant Load Factor

A

the amount of floor area presumed to be occupied by one person. Based on the generic function of building spaces

25
Q

Common path of egress travel

A

Portion of the exit access travel distance measured from the most remote point within a story to the point where occupants have separate access to two exits or exit access doorways.

26
Q

Exit Access Travel Distance

A

distance that an occupant would have to travel to get from the most remote point in the occupied exit access area to the exit
