What keeps a fire burning? The answer lies in the Fire Tetrahedron: four elements working together to sustain combustion.
🔥 Heat initiates the combustion process by bringing fuel to its ignition point.
🔥 Fuel provides the combustible material that allows a fire to ignite and grow.
🔥 Oxygen fuels the combustion process, helping a fire grow and spread.
🔥 Chemical Chain Reaction sustains the combustion process, allowing the fire to continue burning.
Remove any one of these elements, and the fire cannot continue to burn. That's the science behind effective fire suppression and why different fire hazards require different extinguishing agents.
🧯 Understanding the Fire Tetrahedron is a foundational step toward safer workplaces and smarter fire protection.
