Cleaning Verification and Residual Contamination Assessment
topic
Cleaning verification for structural firefighting clothing uses portable fluorescence detection tools that identify the characteristic fluorescence of PAH contaminants remaining in outer shell fabric after laundering, providing field-usable assessment of contamination residue that quantitative laboratory analysis methods reveal, enabling decisions about whether additional cleaning cycles or clothing retirement are warranted based on actual contaminant residue rather than appearance-based assessment that cannot detect non-visible PAH contamination.
Role
Provides practical tools for assessing the effectiveness of decontamination and laundering in reducing actual carcinogen contamination in firefighting clothing, addressing the inadequacy of visual inspection for detecting the invisible PAH contamination that represents the primary cancer exposure risk, with contamination assessment tools enabling informed decisions about clothing reuse after fire operations rather than relying on appearance that does not correlate with chemical contamination level.
