Demystify: 

Hi Monana - We too only have two passenger elevators as our freight elevator got nixed in the original construction in the early 90s. We are just finishing up a renovation and I tried like crazy to get them to add a freight elevator in, but to no avail. They wanted $250,000 for the added elevator.

The best I have been able to do is get the run key from our elevator mechanic. This allows us to lock out the unit for transport (will not open on intermediate floors). However, that does not keep folks from riding with LN2 tanks!

Oh Christina, that is going to do it. Many, many thanks. And thanks to the NFPA 45 committee who put a wee bit of common sense into the standard. I found a lot of university policies that stated only the freight ekevator should be used for transport. This job I'm on is a renovation, so we are stuck with only two passenger elevators.

The 2019 edition reference is A.8.3.3.1 and this edition has an additional sentence tacked to the end of the statement. "Transport of flammable, corrosive, toxic or highly toxic gases, cryogenic cylinders or dewars, or dry ice and similar oxygen depleting compounds should always be done with no one in the elevator."

The "non-requirement" is found in Annex A of NFPA 45, A.8.2.3.1. I suspect that the "suggestion-to-requirement" will be up to the Authority Having Jurisdiction.
