No, it's more important get people out of danger first. You don't discuss how to put out a fire while people are burning inside.
Who taught you how to fight fires? You not might discuss INSTEAD of acting but you definitely discuss BEFORE you run in and get trapped yourself. "Hey, Chief, this wall looks like its going to collapse! Let's go through the back door instead."
Plus a little discussion can lead to a great benefit overall: the firefighters & bystanders stay safe. Some go in to do the rescue of those already in danger, some stay back in case the rescues get trapped, still other fight the fire so it doesn't spread and put the neighbors in danger, etc.
