If there is a fire indoors that you cannot extinguish very, very quickly, you need to immediately get out and call the emergency services. The longer you wait, the larger the fire gets and the less professionals can do about it. Don't try to be a hero and flood batteries from your 10 litres/minute faucet. Just get out before you inhale too much smoke, faint, and die.
