Early detection of creosote contamination is a vital step in fire investigations. LCS Laboratory is proud to introduce a new service: the analysis of wipe samples for the detection of creosote tar. Creosote, a byproduct of incomplete combustion of construction materials during fire, often contains polycondensed aromatic compounds (PCA), a broad group of aromatic chemicals that includes carcinogenic compounds like polycyclic aromatic hydrocarbons (PAHs). Early detection of creosote is critical for mitigating health risksof tenants, and ensuring proper cleaning of affected areas.
Why Early Detection of Creosote Matters Creosote residue may pose significant health hazards due to its PCA content. Early identification allows investigators to assess contamination levels, guide remediation efforts, and protect individuals from prolonged exposure to harmful compounds.
How the Test Works Our analysis follows the NIOSH 9102 sampling technique, ensuring reliability and accuracy. Here’s how it works:
- Sample Collection: Clients collect surface samples using pre-approved wipes.
- Delivery: Samples are sent to our laboratory in London, Ontario.
- Extraction: PCA is extracted from the wipes in our laboratory.
- Analysis: Thin Layer Chromatography (TLC) is used to detect PCA as signature compounds of creosote.
Test Sensitivity and Results This is a qualitative test where creosote on wipe samples is reported as either “detected” or “not detected.” Our method achieves a typical sensitivity of 1 µg per wipe sample, offering reliable results for your investigation.
