Pink Fire Retardant

Recent wildfires in Southern California have brought into light the use of pink fire retardant as authorities deploy aerial resources to combat the flames.

• Pink fire retardant is used to slow or extinguish wildfires, primarily made of ammonium phosphate-based slurry.
• The most common brand in the U.S. is Phos-Chek.
• The pink color aids visibility for firefighters in identifying treated areas.
• It includes salts like ammonium polyphosphate, which remain effective longer than water.
• It is deployed from aircraft like planes and helicopters for effective coverage.
