Which term describes the structural feature designed to resist fire spread within a building and extend from the foundation through the roof?

• A. Fire Walls
• B. Fire stops
• C. Draft curtains
• D. Exit discharge

Answer: (A)

Fire walls are walls designed to resist fire spread and run continuously from the foundation up through the roof. Their main job is to create compartments within a building so fire and heat cannot easily cross from one area to another, which helps limit damage, protects egress routes, and gives occupants time to evacuate while firefighters gain access. They’re built as fire-resistance rated barriers and must be continuous, with penetrations that are properly fire-stopped to maintain their integrity through all levels of the structure. This is what sets them apart from fire stops, which are intended to block flame in concealed spaces but don’t span the entire building; draft curtains, which control air movement rather than fire containment; and exit discharge, which refers to the area where occupants leave the building.
