Re-Contamination of Soot & Dust
Often after a fire it is necessary to clean nearby and/or adjoining offices or rooms to make them usable while work begins and progresses in the area where the fire occurred.
Most of the time, this works out fine with only a bit of inconvenience.
Sometimes there is a bit of a smell or something minor for a while.
And then sometimes, each day greets you with a new round of soot and dust on the flat surfaces. While it gets less and less after each cleaning, it is a frustration.
Are the doors being opened too much while air is being disturbed in the fire damage area?
Are doors or windows to the outside opened in the fire damage area?
Is the HVAC system somehow getting new soot in it?
It becomes a mystery to solve.
