The amount of dust that would get poured into the room would almost certainly set off the fire suppression system, sucking the oxygen out of the room within 30 seconds of activation and suffocating anyone left inside.
Also the fire suppression systems usually dump gases like nitrogen, argon, CO2 etc toreduce the O2 percentage in a room. They also don’t work as well with a venting hole. A mask with a small O2 container like they use for climbing is recommended.
