Gas bottles that you order through ebuy are delivered to the gas cage behind 70/70A. You need a key to access the cage. We have a communal key. It is hanging on the side of the grey cabinet, on the left as you enter the lab. ALWAYS replace the key immediately after using it.
If you want your own key to the cage, fill out a key request form. For building, put 70. For room number, put “gas cage on loading dock behind B70.” I verified with the lock shop that they can parse this information and send the correct key.
