According to the International Building Code (IBC), what is a fire partition, and where is it used?
correct answers The IBC defines this as a wall assembly having a fire resistance rating of one
hour, used in:
1. Walls separating dwelling units
2. Walls separating guest rooms in Group R-1, R-2, and I-I occupancies
3. Walls separating tenant spaces in covered malls
4. Corridor walls
What two situations require the construction of a fire barrier? correct answers This type of fire-
resistance-rated wall is required as:
1. A separation where there are different occupancies
2. An enclosure where there are vertical exits
, What is the maximum percentage of wall or ceiling area that combustible trim (such as trim
made of wood) can occupy in a room? correct answers In a room, this material type can occupy
no more than 10% of a wall or ceiling area.
What is an occupancy class, and what is it used for? correct answers This is a usage classification
assigned to a building or interior space. It differentiates various types of fire hazards and the life-
safety characteristics of various uses.
What is mixed occupancy? correct answers This is a situation where a single building or interior
space houses two or more different types of occupancies.
What is an accessory occupancy? correct answers This is a space or a room that is used in
conjunction with the main occupancy, but contains no more than 10% of the floor area of the
main occupancy.

fire barrier, be equipped with an automatic sprinkler system, or both.

answers There are five of these, and Type I has the highest fire resistance.
What is fire-resistance-rated glazing? correct answers This is glass or some other glazing

In regard to interior design, what is a guard, and what dimension must it have in commercial

What is an occupant load factor? correct answers This is the amount of floor space that a
building code presumes is occupied by one person in a particular occupancy.
How is the occupant load of a space calculated? correct answers To calculate this value for a
space, the total area in square feet is divided by the occupant load factor.
