Pollutants created by oil furnace failure

I recently received a call from an individual whose furnace failed,
producing what is known in the home heating industry as a "puff
back".  The residence houses a collection of works of art on paper,
a flag, several wooden sculptures, metal objects, and audio
equipment.

I am interested in references on the types of air pollution and
residues created by such a misfortune.  I would appreciate
information on the corrosive pollutants created, as well as any
suggestions for intervention.
