How are structures that include hazardous materials classified in the International Building Code?

Structures that include hazardous materials are classified as High hazard (Group H) occupancies under the International Building Code. This classification is crucial as it specifically addresses buildings designed to house processes or materials that pose significant risks to public safety and health.

Group H occupancies are further divided into different subcategories based on the level and nature of hazards. For example, they might involve highly flammable liquids, toxic chemicals, or explosive materials. The regulations regarding these structures aim to mitigate risks associated with the storage, use, and exposure to hazardous materials, ensuring that appropriate safety measures and construction techniques are employed.

The other options refer to different categories of occupancies which do not inherently involve hazardous materials. For instance, service occupancies primarily focus on facilities that provide services to the public and do not typically involve hazards at the level covered by Group H. Normal hazard occupancies deal with spaces that may have some risks, but they are not on the same level as those found in high hazard situations. Assembly occupancies include buildings where a large number of persons gather, but the focus is on crowd management and egress rather than hazardous material risks. Therefore, classifying buildings with hazardous materials as High hazard (Group H) offers the necessary oversight to safeguard people and property
