Fire and Smoke Damage

Our environmental team recognizes the dangers that remain after a fire, and are equipped to ensure your team is safe.

After a fire, your building may be contaminated by char, black carbon/soot, and ash. By testing for the presence of analytes of interest, Farmer Environmental can provide vital information on the extent of the damage done by fire. These results can be used for cleaning assessments or insurance claims.

Know the Facts

  • Char is defined as a particulate larger than 1 μm that is made by incomplete combustion. Carbon is often a predominant component in char.
  • Ash is characterized by pyrolyzed material from the combustion of char. Ash is mineral-based and loaded with elements such as calcium, potassium, magnesium, and more.
  • Soot is a submicron black powder produced as a by-product of combustion or pyrolysis. Black carbon/soot is the black material emitted from gas and diesel engines, coal-fired powerplants, and sources burning fossil fuels.


These three effects of fire and smoke damage can cause several health problems, such as respiratory problems, cardiovascular diseases, congenital disabilities, and more.



Farmer Environmental Group provides fire and smoke damage testing to protect you and your environment. By air sampling and surface sampling, our team tests for the residues of analytes of interest.

Surface sampling can be done through:

  • Alcohol prep wipes
  • Microvacuum
  • Bulk samples
  • Tape lifts.

We also offer air sampling in the form of:

  • PVC pre-weighted cassettes
  • Zefron CSI cassettes
  • Zefron Air-o-cells
  • MCE cassettes.

All of the above have advantages and disadvantages, but Farmer Environmental Group ensures that we will conduct sampling most beneficial to you and your building space.
