Does anyone have a rule of thumb for a ventilation rate in a room which is being used to store liquid nitrogen containers? Several credible web sources recommend a "well-ventilated area" without mentioning numbers. We have a room under consideration for this purpose with about 1 air change per hour. This seems low to me, but I thought I would sanity check it with DCHAS-L.
Thanks for any help with this.
