Forest-fire fighting
Early fire retardants were mixtures of water and thickening agents, and later included borates and ammonium phosphates. Generally, fire retardants are dropped from aircraft or applied by ground crews around a wildfire's edges in an effort to contain its spread.

What is fire retardant made from?

Fire retardants consist of detergent chemicals made from a combination of wetting agents and foaming chemicals, fertilisers (ammonium and diammonium sulfate and ammonium phosphate) mixed with thickeners (guar gum) and corrosion inhibitors (for aircraft safety). They are mixed with water to form a foam or slurry.
