How can a fire suppression system interact with the fire triangle?

A fire suppression system is designed to extinguish fires by interrupting at least one side of the fire triangle, which consists of heat, fuel, and oxygen. The correct choice reflects how these systems effectively extinguish fires.

By reducing oxygen and heat, fire suppression systems can effectively eliminate two of the three essential components needed for combustion. For instance, in the case of a water-based suppression system, the water not only cools down the heat but also displaces oxygen in the vicinity of the flames. Other suppression methods, like CO2 systems, remove oxygen directly from the area, thereby suffocating the fire.

This approach to extinguishing fires is why the selected answer is accurate and relevant to the function of fire suppression systems. In contrast, adding more fuel, maintaining heat levels, or enhancing visibility do not align with the principles of fire suppression, as these would either fuel the fire or increase its intensity, which is contrary to the goal of extinguishing it.
