I'm sure this is a really stupid question--but here goes anyway. We are considering staying at the Hotel Monasterio before our Inca Trail journey next year.
I'm wondering how it can be safe to have oxygen be pumped into the rooms? If there's an earthquake and a pipe breaks, would there be an explosion? If there is a spark (maybe from the heater?) in your room, could there be a fire?
I don't know why I thought of this. But, now maybe some scientist (or not) out there can explain how this works. I assume it must be safe--or they wouldn't do it!
