What defines light hazard occupancies?

Light hazard occupancies are characterized by a low quantity and low combustibility of contents found within the space. This classification is designed for areas where the likelihood of fire growth, as well as the potential for fire spread, is minimal due to the types of materials present. In light hazard environments, materials are often non-combustible or have low flame spread characteristics, making them less likely to ignite and promote significant fire conditions.

The defining criteria emphasize that these locations are generally used for activities that do not involve substantial storage of highly combustible materials or flammable liquids, which can significantly alter the fire risk profile. As a result, fire protection systems in these occupancies are designed with a focus on preventing fire escalation rather than suppressing large-scale fires.

Other choices describe conditions that would categorize an occupancy as moderate or high hazard, where any of the listed elements significantly increase fire risk and necessitate different fire safety measures.
