π₯ HOW DO WE EXTINGUISH A FIRE?
Fire can be controlled by removing one or more elements needed for combustion. Fire protection principles commonly describe four basic methods of extinguishment:
π§ COOLING β Removes heat, commonly by applying water.
π SMOTHERING β Limits the oxygen available to support combustion.
β½ FUEL REMOVAL / STARVATION β Removes, shuts off, or isolates the fuel feeding the fire.
π§― CHEMICAL CHAIN REACTION INHIBITION β Interrupts the chemical reactions that sustain flaming combustion, as with certain extinguishing agents.
These principles relate to the fire tetrahedron: heat, fuel, oxygen, and the chemical chain reaction.
β οΈ Remember: The correct extinguishing method depends on the fuel, fire conditions, and hazards present. Water is not appropriate for every fire.
Know the fire. Know the method. Use the right extinguishing agent.
