What type of occupancy has stockpiles that do not exceed 12 feet?

The correct answer pertains to the classification of occupancies based on fire hazards, and specifically, ordinary hazard occupancies are designed to accommodate a specific level of risk related to the materials stored within them.

In the case of ordinary hazard occupancies group 2, these typically involve situations where the storage of materials does not exceed certain dimensions, including stockpiles. When stockpiles are limited to a height of 12 feet, this aligns with the criteria for ordinary hazard occupancies group 2. This classification encompasses materials that have a moderate fire risk, where the arrangement and height limitations of the stockpile mitigate potential hazards.

Understanding these classifications is essential for determining appropriate fire protection measures, including sprinkler system design and installation. Group 2 is specifically tailored to balance operational needs and safety measures, ensuring that the risk of fire is managed effectively based on the characteristics of the stored materials.
