How to remove helium gas in case of a quench

Hello all:

We are planning to install a shielded 800 MHz magnet in a relatively small room
(30 x 40 ft, 8 ft ceiling height). The magnet is going to sit in a dip.
In case of a quench, the amount of helium gas will be huge for a shielded
800 magnet. Has anyone installed such magnet in a relatively small room?
What methods (fan or pipe to the outside) you planned to use to remove the
helium gas in case of a quench?

Any comment is appreciated.

Thanks,
