FAQ. Hi, my home has smoke contamination. Although I left the windows open for a few days and the majority of the smoke smell has dissipated, there is still a faint odor that gives me a head ache … Possibly the heavier components of smoke? How can I test to determine what it is?
Answer: Hello, thank you for asking. The smell of smoke after a fire is caused by semi-volatile organic compounds with boiling points from 200C to 500C. Smelly, tar-like residue is called “creosote”. Some compounds of the creosote are so heavy, that it may take weeks or months before they evaporate and the smell goes away by itself.
To reduce smell of smoke in you house, you need to remove as much creosote as you can. Before you start, remember that creosote may (and may not) contain toxic components like Polycyclic Aromatic Compounds . Wear rubber gloves to avoid skin contact with creosote. The cleaning supplies can be very irritating, please read the manufacturer’s instructions and keep the windows open. If you experience a headache, or any discomfort from the smell, use personal protection equipment (respirator) with “solvent” cartridges.
