Non-Required Shaft Protection

Builder Bob said:
A diagram or floor layout would be very helpful... However, this is a trainging prop for the FD to learn about stairwell ventilation, stand pipe operations, rescue operations, etc. If the stairway is separated from the interior (normally occupied) areas fo the building, then it shouldn't matter that the stairway has openings that are unprotected or is attached to the garage.......If the opening protectives are really a big issue, have the exterior wall where the stairway abur constructed as a firewall ---- then the stairway is not a normally occupied building and could be a U type occupancy for traingin purposes.

Thanks, "U" seems more restrictive though open to interpretation. Think "B" is more appropriate to use Table 508.3 as applicable.

Are the exhaust fans actually used to evacuate smoke, if so how is it generated?
