Extinguishers suitable for Class A fires should be identified by which geometric symbol?

Explanation:
Classifying extinguishers by the class of fire they handle is the key idea. Each extinguisher type uses a simple geometric pictogram to show its appropriate use. For Class A fires, which involve ordinary combustibles like wood and paper, the symbol shown is a triangle. This quick visual cue helps responders pick the right extinguisher at a glance and avoids using extinguishers on the wrong type of fire. The other symbols correspond to other classes: a circle for Class B, a square for Class C, and a diamond for Class D.
