, What is the common path of egress travel? - ANSWER- This is the portion of an exit
access that occupants are required to traverse before two separate and distinct paths of
egress travel to two exits become available (from most remote point in space).
What are the two main factors in determining if a space requires two exits rather than
just one? - ANSWER- The two main factors that determine how many of these are
required are the space's occupancy and it's occupant load.

a space, what is the minimum separation required? - ANSWER- The minimum
separation required is one-third the diagonal distance of the space.
What is an exit access travel distance? - ANSWER- This is the distance an occupant
must travel from the most remote point within a building to the entrance of the nearest
exit.
How is the minimum exit width calculated? - ANSWER- This is calculated by multiplying
the occupant load of a space by the appropriate factor given in the building code.
For an occupant load greater than 50, what is the absolute minimum corridor width? -
ANSWER- In this distance, the minimum corridor width is 44in.
Within a means of egress system, what are exit access areas? - ANSWER- Within a
means of egress system, these are areas that do not provide a protected path of travel
and which lead to the entrance of an exit. In the International Building Code, even fire-
rated corridors are included in this category.
