An extinguisher's rating reflects its ability to prevent rekindling.

• A. True
• B. False
• C. Partially true
• D. Not specified

Answer: (A)

Extinguisher ratings indicate how effectively the device can extinguish a fire and keep it from reigniting under the tested conditions. The rating reflects the cooling, smothering, and fuel-separation actions that help prevent rekindling after the flames are knocked down, for the specified fire size. So this statement is true because the rating is tied to the extinguisher’s overall ability to finish the job and prevent re-ignition, not just how quickly it sprays or how large a fire it can start with.
