What is the classification for ordinary hazard (group I) occupancies?

The classification for ordinary hazard (group I) occupancies is accurately identified as low combustibility with moderate combustibles. This classification encompasses structures that contain a combination of materials that, while not highly flammable, may still pose a moderate risk of fire due to the presence of combustible materials.

In ordinary hazard occupancies, the risk comes from materials that can ignite and may contribute to the spread of fire, but these materials are typically less hazardous compared to those found in higher hazard categories. For instance, these occupancies may include places like warehouses or light manufacturing, where finished products and materials are present but are not of the most combustible nature.

Thus, understanding this classification helps in designing appropriate fire protection measures, sprinkler systems, and emergency response plans relevant to the specific risks posed by ordinary hazard environments.
