Working under the IBC, a designer has determined that an 8 ft total exit width is needed
from a store. What combination of door widths would meet most exiting requirements?
, A.) one 36 in door remotely located from a pair of 34 in doors
B.) a pair of 32 in doors remotely located from one 38 in door
C.) three 36 in doors remotely located
D.) three 34 in doors remotely located - ANSWER C is correct. Options A, B and D
include doors that would provide less than a clear 32 in wide opening.
In a 90,000 feet squared, single-story office building, what would be of greatest concern
in space planning?
A.) dead-end corridors
B.) corridor widths
C.) horizontal exits
D.) travel distances - ANSWER D is correct. A 90,000 ft. squared building would be
approximately 300 ft. squared or about 250 ft. wide and 360 ft. long. The size combined
with typical rectangular planning of corridors would create very long distances to exits.
A client has hired you to design a new entry into her consulting business, that is in an
old, unsprinklered building. The client's space must meet current IBC requirements. The
existing entry consists of a pair of all-glass doors mounted on floor closers. The entry
opens onto a 1 hour rated building corridor. What does the designer tell a client to
expect regarding the new entry?
A.) smoke seals will have to be located around the edges of the glass doors.
B.) the glass doors will have to be replaced
C.) One of the doors will have to be removed.
D.) The floor closers will have to be changed to hinges. - ANSWER B is correct. Smoke
seals will be required; most importantly, though, the glass doors will need to be
replaced with either solid, 20-minute-rated doors or those made of 20-minute-rated
glass. Because this will dramatically alter the appearance of the existing entry, this is
the first thing they should expect to be told. It's either pivoted floor closers or hinges
may be used provided they're also fire-rated and the door is side-swinging.
Which one of the following statements is NOT correct regarding fire-rated door
assemblies?
A.) Either hinges or rated pivots may be used.
B.) Under some circumstances a closer in not needed.
