Just curiosity but... why?
Sudden burst of air from outside might cause the fire to go boom and bigger
... If she didnt open some windows she might die from the fire itself or from carbon monoxide poisoning, so yeah why?
They’re advising people who might have house fires. Don’t open the windows to try to get rid of the fire, it will just make it worse.
Could she have used her dress to smother it?
Just open the windows gradually. Don't throw them open.
PSA: DON'T GO BUSTING OPEN WINDOWS DURING A FIRE GUYS.. Big No-No!! Σ(っ°Д °;)っ
