Which hazard is associated with fire fighting foam concentrate?

• A. Skin irritation.
• B. Degradation of PPE if left on the garments for a long period of time.
• C. Allergic reactions.
• D. Electrical hazards.

Answer: (B)

Foam concentrates can contain solvents and surfactants that are chemically aggressive to protective gear. When foam remains on turnout gear, seals, gaskets, and the fabric fibers can be affected over time—the materials may swell, weaken, or break down. This degrades the protective barrier of the PPE, increasing the risk of exposure and gear failure during future work. That’s why the hazard is framed as degradation of PPE from prolonged contact with foam residues.

It's worth noting that skin irritation or allergic reactions can occur from foam exposure, but the impact on PPE integrity is the bigger safety concern because it directly compromises protection. Electrical hazards aren’t a direct property of the foam itself, though damaged PPE could create other risks. After foam use, promptly rinse and decontaminate gear and inspect for damage before reuse.
