Correct answer to question 168 (Passenger): Suddenly introducing more oxygen can cause the fire to flare up more intensely

Why

Suddenly exposing a fire to more oxygen by fully opening the hood can cause it to flare up, so a partial opening or using a designated access point, according to training, is generally safer than opening it all the way.
