Can vinegar and baking soda be used as a fire extinguisher?

What chemical is in a fire extinguisher?

Carbon dioxide is a compressed gas agent that prevents combustion by displacing the oxygen in the air surrounding the fire. The two types of dry chemical extinguishers include one that contains ordinary sodium potassium bicarbonate, urea potassium bicarbonate, and potassium chloride base agents.

Is baking soda acidic or basic?

Baking soda is an alkaline substance. When it mixes with an acid, it alters the pH level. That’s why it can quickly soothe an upset stomach or cover a bad smell.

How does a sodium bicarbonate fire extinguisher work?

Sodium bicarbonate is used in most dry fire extinguishers. When dispensed, the products absorb heat, decompose to form fire smothering carbon dioxide, and release free radicals which interrupt the flame chain reaction mechanism.
