AFF Exit Exam • Set 6 Question 22 of 30

Which extinguishing agent is most likely to allow reflash as a result of not cooling the fuel below its ignition temperature?

✓

Direct Answer

Option C: CO2

CO2 is a gaseous extinguishing agent that works by displacing oxygen and cooling. However, it does not effectively cool the burning fuel below its ignition temperature, making reflash a significant risk once the CO2 disperses.

All Options

Aqueous film-forming foam (AFFF)

Dry chemical powder mix

CO2 (Correct Answer)

Water fog stream

Detailed Explanation & Context

Relevant Framework: STCW 2010 Manila Amendments • DG Shipping E-Learning & Exit Exam Standards • Advanced Fire Fighting (AFF).
