Which factor is cited as a key criterion for storage facility classification under model codes?

• A. The combustibility or flammability of its contents and storage method
• B. The presence of a sprinkler system
• C. The building's age
• D. The owner's preference

Answer: (A)

The main idea behind classifying storage facilities in model codes is the fire hazard created by what is stored and how it is stored. The combustibility or flammability of the contents and the way they are stored (packaging, arrangement, separation, and handling practices) directly determine how quickly a fire could start and spread, which drives the facility’s hazard classification. Protective features like a sprinkler system influence design and protection requirements, but they do not determine the hazard class itself. Factors such as the building’s age or the owner’s preference don’t define the storage hazard category either.
