The article discusses how firefighters in the Greater Los Angeles area use pink fire retardant to combat wildfires. Once the strong Santa Ana winds weaken, air support becomes effective. The pink color of the retardant, derived from iron oxide dyes, helps in tracking the application of the agent during firefighting efforts. Flame retardants function by mitigating the combustion process through chemical reactions that inhibit ignitability and slow flame spread, employing pyrolisis and endothermic decomposition to protect materials and control flames more effectively.
When the infamous, hairdryer-like Santa Ana winds weaken, the devastating fires in the Greater Los Angeles area can be fought from the air.
Bright dyes made from iron oxide are added to fire-extinguishing water or agents, giving them their eye-catching pink or red color.
Flame retardants work due to both their chemical and physical properties, delaying the ignition of flammable materials and preventing the spread of flames.
Retardants cause gases emitted during a fire to react with radicals, neutralizing them and stopping the chain reactions responsible for sustaining the fire.
