Ralph,

While you are waiting on the answer from a regulatory standpoint, you may want to consider this from a practical standpoint. Our folks tend to worry more about the materials the door is made of and whether or not the swing would interfere with the field. That tends to make the swing go in the same direction you are pondering.

Subject: [DCHAS-L] Door swing in NMR room?

A question has arisen here with regard to the direction of the entrance door swing in a room containing an NMR. Some people have suggested that due to the asphyxiation potential of a quenching of the instrument, the door should swing out of the room into hallway. Does anyone know of a regulatory requirement for this or a reference that suggests that this be used as a best practice?

Thanks for any help with this.
