Post Fire Clean-up Procedures for Asthmatics

Our local hospital is looking for any specific advice on post-fire clean-up for asthmatic family members.  

I've received great advice from NCHH including hiring a RIA/IICRC certified professional cleaning company, focusing on water clean-up and dehumidification, smoke and soot clean-up under negative pressure, and NYDOH resources.

Anyone have anything to add that is asthma-specific?  e.g. certain chemicals to recommend/avoid as part of the clean-up effort?
