LCS Laboratory Inc. is offering analysis of smoke pitch deposits on surfaces following fire damage. Our expertise in industrial hygiene and surface contamination testing ensures the accurate identification of hazardous residues, providing technical support for remediation and safety evaluations of fire damages.When a fire occurs, dark, oily condensates often settle on cold surfaces. These deposits are chemically similar to coal tar pitch and can contain carcinogenic Polynuclear Aromatic Hydrocarbons (PAHs). Detection of these compounds is critical for assessing fire damage, verifying remediation efforts, and safeguarding the health of the cleaning crew and the tenants.
Surface Sampling for PAHs: Precision and Compliance
Our laboratory developed precise analysis of PAHs using surface sampling. We recommend using paper ashless filters wetted with IPA to collect samples from non-porous surfaces such as glass, stainless steel, or ceramics. Wear polyethylene gloves when you collect samples. Samples are standardized to 100 cm² to ensure consistent results. The sampling procedure should follow NIOSH 9102 standard.
When we receive the samples, we extract PAH’s from the filters and identify them using HPLC UV following the analytical procedure from NIOSH 5506 method. This detailed analysis provides clients with concentrations of 16 individual PAH’s.
For accurate results, avoid collecting samples from plastics, waxed or varnished furniture, or other materials that may yield organic products, and produce false positive results. Use a glass container for shipping and protect samples from direct light. A blank sample must accompany every batch submitted for analysis to maintain rigorous quality control.
Applications of PAH Testing
Our PAH testing services can be used for:
- Post-fire damage assessment: Confirm the extent of chemical residues after a fire.
- Remediation verification: Evaluate the effectiveness of cleaning and restoration efforts.
- Health and safety compliance: Ensure environments meet industrial hygiene standards for chemical safety.
