The BAE146 has featured prominently in fume events, even to the extent that crew have retired on medical grounds. The manufacturers simply didn't anticipate the occurrence of contaminated air beyond the usual electrical smoke or other obvious possibilities so there isn't really a set down procedure specifically for it. It's supposed to fall under the generic SMOKE/FIRE/FUMES checklist.
In the early days of jet flying, the FAA didn't permit engine bleed air to be used for cabin pressurisation, the B707 had compressors mounted on top of engines 2,3 and 4. The DC8 had them in the nose.
