The type of extinguisher that interrupts the chemical reaction of combustion is the Halon extinguisher. Halon works by displacing oxygen and interrupting the combustion process, which involves three essential elements: heat, fuel, and oxygen. By targeting the chemical reactions occurring during a fire, Halon effectively stops the fire from continuing.

Water-based extinguishers primarily work by cooling the fire and removing heat. Dry chemical extinguishers are effective in smothering flames by covering the fuel, but they don't directly interrupt the chemical reaction in the same way Halon does. Carbon dioxide extinguishers remove oxygen from the environment and lower the temperature of the fire but are not specifically designed to interrupt the chemical reactions at play during combustion.

This understanding of how each type of extinguisher functions is crucial for effectively responding to different fire scenarios in a correctional setting or any environment where fire safety is a priority.
