PICS: Surreal Los Angeles turns pink as fire retardant rains down

Clarence Ford interviews Barbara Friedman about this and other trending news on social media.

Listen below.

As wildfires continue to ravage Southern California, pink fire retardant has been falling from the skies over Los Angeles.

The substance being deployed to combat the flames is called Phos-Chek.

Primarily composed of water, ammonium phosphate (a compound commonly found in fertiliser), and pink dye, Phos-Chek is thickened with gum to enhance the precision of aerial drops.

Typically, plants exposed to a fire’s intense heat decompose and become additional fuel.

However, Phos-Chek creates a protective coating that absorbs the heat energy, slowing the fire’s spread.

The chemical reaction produces a nonflammable carbon material, slowing the blaze and giving firefighters crucial time to control the flames.

"The pictures are surreal."
