Ordinary Hazard (Group 1) is defined as which condition?

• A. Moderate combustibility with moderate heat release.
• B. Low combustibility with minimal heat release.
• C. Very high combustibility with rapid heat release.
• D. Low to moderate combustibility with limited height limits.

Answer: (A)

Ordinary Hazard (Group 1) is defined by a moderate level of combustibility with a moderate rate of heat release. This category fits typical residential occupancies with standard furnishings—not as mild as light hazard, but not as severe as higher hazard levels. The other descriptions describe conditions that are either lower fuel/heat (light hazard), much higher fuel/heat (extra or higher hazard), or introduce factors like height limits that aren’t part of hazard classification. So the best match is moderate combustibility with moderate heat release.
