What’s the beer for? To be paired with the human ham I’ll turn into if I am exposed to 100 °C for too long?

Yes you do need to be prepared. If you’re inside a fire and even if it just started a few minutes ago, the ashes and black smoke will get so thick you will barely see an arm’s length in front of you, and there will be complete opacity 2 meters in front of you. Also people can panick and make bad decisions, I’ve seen two people freaking out over a fire extinguisher “not working” because they were too scared to think straight. I’ve had to show them to slow down, read the instructions on the sticker, follow the steps and then empty the can. Fire drills and preparation will probably save your life if you’re ever in a fire, and it may even help you save other people’s lives.
