Smoke damage contains a particle signature of the source. House fires, forest fires, brush fires, fireplace smoke, industrial fires, cigarettes, trucks, kitchen fires, etc. all leave a characteristic signature.

Some of the particles that mark these sources are shown here.

Charred Wood from a House Fire

This is a piece of charred Douglas fir (upper) and a hardwood from the structural wood used in this home. This particle was collected on a tape-lift taken on the second floor of a home that had a fire in the basement. This was carried upstairs by the chimney effect through the stairwells.

We can identify the source and if the environment (i.e home, office, school) has been impacted by smoke from that particular source.
