Question: 1 / 400

Which fire extinguisher classification is suitable for electrical fires?

A:B

The classification suitable for electrical fires is B:C. Fire extinguishers designated with the letter "B" are effective against flammable liquids, while those marked with "C" are specifically designed for use on electrical fires. This makes the B:C classification the appropriate choice for tackling fires that involve electrical equipment, as using water or other non-suitable extinguishers could pose a risk of electrocution.

While some classifications may offer protection against different types of fires, not all are suitable for electrical emergencies. For instance, an A:B extinguisher, while effective for wood, paper, and flammable liquids, does not provide the necessary protection for electrical fires. Therefore, the B:C choice is crucial for safely extinguishing electrical fires without introducing further hazards.
