Which of the following is NOT a side of the Fire Triangle?

The Fire Triangle is a fundamental concept in fire science that outlines the three essential elements required for a fire to ignite and sustain itself: oxygen, heat, and fuel. Each element plays a critical role; for instance, oxygen supports combustion, heat provides the necessary energy for the reaction, and fuel is the material that burns.

Water, however, is not a component of the Fire Triangle. Instead, it is commonly used as a fire suppression agent because it can effectively cool the heat and displace the oxygen when applied to a fire, thus interrupting the triangle's elements and extinguishing the flames. This understanding highlights the importance of recognizing the correct factors essential for a fire to occur and being aware of effective fire-fighting strategies.
