The goal of providing adequate Fire-Stopping is to ______________the spread of smoke and fire throughout the building.

• A. limit
• B. prevent
• C. contain
• D. reduce

Answer: (A)

Fire-stopping is a measure that preserves the integrity of fire barriers by sealing openings and penetrations in walls and floors. Its purpose is to limit how quickly and how far smoke and fire can travel between compartments. It’s about slowing the spread to buy time for occupant evacuation and for firefighters to respond, not guaranteeing that fire or smoke will be completely stopped everywhere. That’s why the best choice is to limit the spread.

Preventing all spread isn’t realistic because there are always some openings or imperfect seals. Containing fire to a single room or area sounds like complete confinement, which relies on the full fire barrier system, not just fire-stopping alone. Reducing spread can be seen as similar to limiting, but the standard objective phrasing emphasizes limiting the spread to maintain safer, more navigable conditions during an incident.
