after another, methodically looking for a solution until you run out of oxygen. We practice the “warn, gather, work” protocol for responding to fire alarms so frequently that it doesnʼt just become second nature; it actually supplants our natural instincts. So when we heard the alarm on the Station, instead of rushing to don masks and arm ourselves with extinguishers, one astronaut calmly got on the intercom to warn that a fire alarm was going off – maybe the Russians couldnʼt hear it in their module – while another went to the computer to see which smoke detector was going off. No one was moving in a leisurely fashion, but the response was one of focused curiosity; as though we were dealing with an abstract puzzle rather than an imminent threat to our survival. To an observer it might have looked a little bizarre, actually: no agitation, no barked commands, no haste." Chris Hadfield - “An Astronautʼs Guide to Life on Earth”
