Question 226Safety & Environmental - QMED
70% to passWhich extinguishing agent is most likely to allow reflash as a result of not cooling the fuel below its ignition temperature?
ACO2
BWater stream
CWater fog
DFoam
AI Explanation
The correct answer is A) CO2. Carbon dioxide (CO2) is an extinguishing agent that works by displacing oxygen, but it does not provide any cooling effect. This means that if the fire source is not removed or the fuel temperature is not lowered below its ignition point, the fire can potentially reflash or reignite. In contrast, water-based extinguishing agents (options B and C) and foam (option D) provide cooling that helps prevent reflash by reducing the fuel temperature.
