A300-B4 with Flight Engineer (me).
Smoke drills very much the same.
Start on page 3 in QRH (mask,goggles, etc.) and then sort out what you have.
Isolate source if possible.
Then page 1 for smoke removal.
We also have Main Deck Cargo Smoke warnings to contend with. Two different conversions, so Two different systems / procedures, and the Simulators don't have this.
All you can do is read the check list on the aircraft every so often to keep fresh and hope it never happens.
One good thing from the Economic downturn, our 2 non-standard A/C are being parked up. (But the contract crews are being layed off though).
Safe Flying.
