Unclassified detonable organic peroxides must be classified as what occupancy?

1. Group H-2

2. Group H-1

3. Group H-3

4. Group H-4

The correct answer is: Group H-1

Unclassified detonable organic peroxides must be classified as Group H-1 occupancy. This classification aligns with the International Building Code (IBC) guidelines regarding hazardous materials. Group H-1 is designated specifically for areas where there is a risk of explosion due to the presence of explosive materials, including organic peroxides that can detonate under certain conditions. Organic peroxides are considered highly reactive and pose a significant risk because they can undergo rapid decomposition, often releasing large amounts of energy and resulting in explosions. Therefore, facilities that handle these substances are subjected to strict safety regulations and building requirements associated with Group H-1 occupancy. This classification emphasizes the need for heightened safety measures, including proper facility design to manage and mitigate potential hazards associated with combustible materials. It’s important to note that other occupancy classifications in the Group H category, such as H-2, H-3, and H-4, correspond to different levels and types of hazards associated with other materials, but the characteristics of unclassified detonable organic peroxides necessitate their classification as Group H-1.
