I am a structural engineer working on a precast mill building and I am trying to better understand the information being provided to me by a explosion venting supplier. My questions is what do you do when the total volume of the building exceeds the 10,000 cubic meter size limitation of NFPA 68 (the building currently has a room that is 30,000 cubic meters that houses the bins)
Is the room so big that it no longer is acting as an enclosure that would be governed by NFPA 68.
I ask because I am being told this room needs to have a vent area that is not practical. What the vent supplier is doing is plugging in the equations assuming a volume of 10,000 cubic meters to get the vent area and then multiplying that number by 3 to get the vent area needed for this room.
Don't know if it helps but this room also has free air vents to the outside.
Thank you for any help
