What term refers to the use of automatic systems, such as sprinklers, to suppress or extinguish a fire?

• A. Compartmentation
• B. Barrier
• C. Evacuation
• D. Automatic Suppression

Answer: (D)

Automatic suppression focuses on automatic fire protection systems that actively work to control or extinguish a fire. Sprinklers are a prime example: when heat is detected, a sprinkler head releases water, cooling the flames and limiting the fire’s growth without anyone needing to intervene. This is categorized as an active fire protection measure because it acts automatically to suppress the fire. By contrast, compartmentation uses fire-rated barriers to slow spread, a barrier is a physical obstruction, and evacuation is about getting people out safely rather than stopping the fire. So, the term that fits is automatic suppression.
