Claustrophobia - can you run out of oxygen in lifts? (2024)

Our fire safety lecture explained that a human can survive on less oxygen than a fire needs, so theoretically even if trapped in an entirely sealed room with a fire, the fire would burn out and we'd still be able to crawl away.

But people get trapped in lifts for hours and are fine, even if lots of people are sharing the air. There is footage online of one poor guy trapped for 41 hours, and barring some minor hallucinations (and presumably problems regarding how to go to the toilet) he was fine.

Never one to be defeated by a challenge, I have searched out trivia from the internet to enable me to calculate how long a person could last on the air in a space 2m cubed....

We breathe using half to one litre of air per breath unless exerting, but we only use up 1/4 of the oxygen in it. We breathe at 6-12 breaths per minute, using around 12 litres of air per minute, but we can use that air 3-4 times before it becomes problematic, so we "use up" 3-4 litres of air per minute. A litre is 10cm*10cm*10cm, so a lift 2m*2m*2m contains 8000 litres of air, enough to last 33.5 hours.

But lifts are of couse never airtight, as they have to comply with a strict code of safety that includes a clause on having "adequate ventilation, even in an emergency" which they are checked against annually! And that level of ventilation is determined by the maximum load capacity (which is many more people than are ever in the lift).

Hope that helps!
