Hi Ralph,

Perhaps this regulation is suitable:


   The door that connects any room to an exit route must swing out in the
direction of exit travel if the room is designed to be occupied by more than
50 people or if the room is a high hazard area (i.e., contains contents that
are likely to burn with extreme rapidity or explode).

	I don't know about a regulation, but we do have the doors to our
labs opening out into the hall so that if there is an emergency, the exit
can't be blocked by a rush of people.

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.
