When I was living in a boarding-school like arrangement for people with disabilities once, they had really sensitive smoke detectors and if you tripped them needlessly, you were in for a hell of liability, because they immediately caused complete evacuation pocedures and an automated emergency call where not just a small contingent of firefighters were called. One night, one person forgot their pasta boiling on the stove and fell asleep on the couch in exhaustion - so deeply and long, that all the water boiled away and the noodles burned and tripped the alarm. That exhaustion cost them several thousands of Euros.
