This is the only "thing" I've seen for this purpose.
Me? I have no idea what I'd do. We have a ladder stored under the bed for ourselves...I guess I'd grab a dog and hope for the best unless it looked like we could get downstairs in the house and then those dogs just better decide that that was the best time of all to obey me. We do have fire extinguishers at various places in the house but I doubt that they'd be any good for anything but a smaller isolated patch of flames.
Now you've got me thinking.....(thank you).
