Continued operation enables sprinklers to achieve full control in roughly how long?

• A. 20 minutes or more
• B. 10 minutes
• C. 5 minutes
• D. 30 seconds

Answer: (A)

Continued sprinkler operation means water keeps flowing after the first sprinklers release, cooling the space and keeping the fire from growing. Full control by this ongoing action isn’t instantaneous; it’s a process that depends on factors like fuel load, compartment size, ventilation, sprinkler density, and water supply. In many cases, achieving full control with continued operation takes on the order of twenty minutes or more, because cooling and flame suppression must be sustained long enough to limit heat, restrict flames, and prevent re-ignition. So the best estimate for full control under continued operation is about 20 minutes or longer.
