Portable fire extinguishers with a rating of 2-A, 40-B:C can be used on which types of fires?

Explanation:
Fire extinguisher ratings show which kinds of fires it can effectively fight. An extinguisher that covers ordinary combustibles, flammable liquids, and energized electrical equipment is designed to suppress fires involving wood, paper, and similar materials; liquids like gasoline or solvents; and electrical equipment that may be energized. That combination means it’s appropriate for those three fire types, making it suitable for ordinary combustibles, flammable liquids, and electrical fires. It isn’t intended for metal fires (which require a different class) or for areas that need specialized extinguishers. When using such an extinguisher, prioritize safety: cut power if possible, aim at the base of the fire, and sweep side to side.
