Find the fire alarm pull stations, fire extinguishers, and fire extinguishing agents. No, wait, just fire extinguishers. And also find the fire alarm.
They're usually marked with a big red sign that says "Fire" and a picture of a fire. Or sometimes just a big red sign with no picture. But it's a red sign, so that's a clue.
Also, check for any fire extinguisher stands with a big red button. If it's not a fire extinguisher stand, it's probably a coffee machine. Don't press the button.
