If an extinguisher is not clearly labeled for the specific fire class, what should you do?

When you can’t tell what fire class an extinguisher is suited for from its label, you should not try to guess or test it. The safest course is to evacuate if the fire is uncertain or growing, call emergency services, and arrange for replacement or a professional evaluation to determine the extinguisher’s proper rating and labeling. Extinguishers are designed for specific fire classes, and using the wrong one can fail to control the fire or even make it worse. This is why guessing or testing with water on a grease-fire, or trying a generic “one-size-fits-all” approach, is dangerous, and ignoring the ambiguity isn’t acceptable.
