Based on UK insurers protocols any FM200 protected space is unsafe for
occupation at such concentration levels. Most companies follow
similar procedures for CO2 systems and evacuate FM200 protected rooms
before the gas is discharged.

Thom,
What makes me worry is that we say FM-200 gas is safe for occupied
spaces & will not affect the personnels in the computer room.
Imagin that the volume of cabinets is about 25% of total volume, so
if my design concentration is 7.4% then the real concentration is
9.25%.
I agree that cabinets are not "Gas Tight" and will become filled
with the FM200 just
at a slower rate, but it takes time, may be for 2 minutes, then can
we still say this gas is safe while the personnels may be subjected
to 9.62% even at the first 2 minutes of gas release?
Thanks,
Reza
Short answer NO!
The cabinets are not "Gas Tight" and will become filled with the
FM200 just
at a slower rate, than the rest of the room.
