When combating a class C fire, which of the following dangers may be present?

Correct Answer: Option C — Toxic fumes from burning insulation or electric shock

Class C fires involve energized electrical components and synthetic insulation. Burning insulation releases toxic gases like hydrogen cyanide or hydrochloric acid, while the presence of live electricity poses an immediate electrocution risk. Firefighters must utilize self-contained breathing apparatus and ensure power isolation to mitigate these specific, life-threatening hazards.
