Fishy or rubbery smell is often a sign of which type of fire?

• A. Electrical fire
• B. Chemical burn
• C. Water leak
• D. Gas leak

Answer: (A)

A fishy or rubbery smell points to an electrical fire. When electrical components overheat or arc, the insulation and rubberized coatings on wires and equipment break down and release distinctive odors, sometimes with a sharp, ozone-like quality. This odor helps identify that the burning source is electrical rather than something else.

Gas leaks typically carry a rotten-egg smell due to added odorants, so a fishy or rubbery scent isn’t the hallmark of a gas leak. Water leaks don’t produce a burning odor, and chemical burns can vary widely in smell depending on the chemical involved but aren’t the same commonly noted electrical-insulation odor. If you encounter this smell near electrical gear, prioritize electrical fire safety: cut power if safe, use the appropriate extinguisher, and evacuate if needed.
