IICRC reopens S700 (fire/smoke) and S520 (mold), adds wildfire provisions

IICRC is revising S700 (fire and smoke) to fold in wildfire cleaning methods, with a member call that closed Jan 31; S520 (mold) and S700 drafts went through public comment that closed Feb 6.

FORFinally a fire standard that addresses wildfire soot and ash instead of pretending it's the same as a kitchen fire, so get your crews trained to it early.
AGAINSTA standard written partly by the people who profit from the work isn't automatically the standard that protects the operator, so read the draft before you cheer.
Consensus vs. contrarianContrarian: the operators who actually submit comments shape the standard they'll be judged by, and almost nobody does, so the few who engage punch way above their weight.
