Fire blankets are also a really good idea, as anyone (including kids) can use them and they're quite effective on say, a stove top that's lit up. Obviously those can get out of hand in a hurry, but in a lot of cases like that, or say, a garbage can or something that's on fire, a blanket can kill it before it gets too big. Obviously if you have any doubt about your ability to fight fire (no matter what tool you have), then get out, but there are plenty of situations where you can contain it if you keep your wits about you, and you have the proper equipment close by. Definitely an extinguisher (hopefully a decent sized one) and a blanket should be mandatory gear on anyone's deck or patio if you have any kind of bbq/grill/smoker happening.
