Pink Fire Retardant
Pink fire retardant, widely used to combat wildfires, is primarily composed of ammonium phosphate salts and is branded as Phos-Chek in the US. It is sprayed ahead of advancing fires to slow their spread by coating vegetation and reducing oxygen availability. While its bright pink hue aids visibility for firefighters, environmental concerns over toxic metals like chromium and cadmium persist. Though effective under specific conditions, its overall impact depends on terrain, weather, and other firefighting strategies. As climate change intensifies wildfires, the reliance on aerial fire retardants grows, sparking debates on their environmental safety and long-term sustainability.
