Factory/Industrial occupancies are characterized by?

• A. Large number of occupants
• B. Factory, subdivided due to use.
• C. Pre-School through 12th grade
• D. 50 or more people

Answer: (B)

Organizational approach by use is what defines a factory or industrial occupancy. These spaces are designed with distinct areas based on the specific processes, materials, or functions happening there—machining, mixing, storage of hazardous substances, assembly, etc.—and are often separated by fire-rated partitions or barriers. This subdivision by use helps contain fires or hazards to a limited area, allows different fire protections tailored to each zone, and supports safer egress planning for workers.

The other ideas aren’t unique identifiers for factory/industrial settings. Large numbers of occupants can occur in many building types, not just industrial ones. Educational spaces are specifically schools, not factories. A numeric threshold like 50 or more people is an occupancy-size rule that applies across various occupancies, not a defining feature of industrial classifications.
