Florida Building Code Practice Exam

Flammable gas in the gaseous state would be stored in which class of building?

1. H-1

2. H-2

3. H-3

4. H-4

The correct answer is: H-2

The correct classification for the storage of flammable gases in their gaseous state falls under Class H-2. This classification pertains to buildings that contain materials categorized as flammable gases or liquids. Specifically, H-2 structures are designed to accommodate the storage and use of flammable gases, ensuring that safety measures, such as ventilation and explosion-proof systems, are in place to mitigate potential hazards associated with these materials. In contrast, Class H-1 pertains to buildings where explosive materials are stored or handled, such as certain solids that can undergo explosive reactions. Class H-3 typically involves the storage of combustible liquids that do not possess the same level of gas-related hazards. Class H-4 focuses on stores containing oxidizers and is primarily concerned with materials that can enhance combustion but aren’t necessarily flammable themselves.
