Nice photo, Andrew, and very good points aabout the installation. I wonder
if this is designated a heritage building? If so, permits will be required.
If so and one goes ahead without the permits, add fines to the cost.
I still think that an industrial hygienist or equivalent needs to be
involved as well as a licensed HVAC engineer to diagnose what kind of
extraction is needed for the contaminants (wood, metal, plastics of
different kinds, solvents???). Maybe one of the profs at Algonquin's new
trades school could advise.
I am not just blowin' smoke here: I live with permanent lung damage from the
days before we knew that we had to have air extraction.
