How are Polycyclic Aromatic Hydrocarbons (PAH) categorized?

Polycyclic Aromatic Hydrocarbons (PAHs) are categorized as carcinogenic by-products. This is due to their chemical structure, which comprises multiple fused aromatic rings, and their ability to form as a result of incomplete combustion of organic material. Numerous studies have provided evidence that exposure to certain PAHs can increase the risk of cancer in humans, making them a significant concern in fire and smoke restoration scenarios. Their presence is often associated with smoke, soot, and various environmental pollutants, reinforcing the need for proper mitigation strategies.

The classification is important in restoration efforts because understanding the risks associated with PAH exposure helps guide safety measures, protective equipment, and remediation processes. Knowing that PAHs are carcinogenic also emphasizes the necessity of thorough cleaning and decontamination in areas impacted by fire, to minimize health risks to occupants and restoration professionals.
