Each of the principal model code organizations has developed ________ that separates each occupancy into categories of risk based upon the use of the structure or space.

• A. standard classifications
• B. occupancy classifications
• C. occupancy risks
• D. hazard comparisons

Answer: (B)

Occupancy classifications are the system model code organizations use to group spaces by their intended use and the associated fire and life-safety risk. By separating occupancies into categories—such as Assembly, Educational, Mercantile, Industrial, and so on—codes tailor requirements for means of egress, fire protection, and structural design to the risk level of each space. This naming and structure is the established way to organize code provisions around how a space is used. The other terms don’t match the formal approach: they’re either too generic or don’t reflect the recognized code framework for categorizing spaces by use and risk.
