What does the term "Ordinary Hazard" signify in occupancy classification?

• A. Less combustibility than light hazard
• B. More combustibility than light hazard
• C. A system area limitation of 25,000 ft²
• D. Automatic sprinkler activation

Answer: (B)

In the context of occupancy classification, the term "Ordinary Hazard" refers to a classification used for buildings or spaces that experience a moderate degree of fire risk. This classification indicates that the materials and contents within these areas are more combustible compared to those found in spaces categorized as "Light Hazard." The Ordinary Hazard classification is typically applied to businesses or storage areas where there is an increased potential for fire due to the presence of combustible materials, but not to the extent seen in "Extra Hazard" classifications. This differentiation is essential for the design and implementation of fire protection systems, particularly automatic sprinklers, as each classification informs the required density and distribution of the suppression system based on the expected risk. While other options mention system area limitations or sprinkler activation, they do not accurately convey the understanding of combustibility and risk associated with the Ordinary Hazard classification. Thus, the identification of Ordinary Hazard as being more combustible than Light Hazard is crucial for proper fire safety planning and management.
