Aircraft
At 31;000 FT in cruise a RED and AUDIO BLEED AIR DUCT message occurred. Ran the appropriate QRH. At that time the engine bleeds closed and the aircraft started a slow decompression. We declared an emergency with Center. At that point; started a very quick descent from 31;000 FT to 8;000 FT due to cabin pressurization rising. At 8;000 FT we finished the QRH; informed the flight attendants of the situation; and we diverted. We did not brace the cabin. Cabin altitude never went above 10;000 FT and the passenger oxygen mask never deployed. Landed with no further events.
A CRJ-700 CAS and AUDIO Warning alerted BLEED AIR DUCT so an emergency was declared; the QRH completed with a descent to 8;000 feet and the flight diverted to a nearby airport.
