Los Angeles, why is the water that firefighting planes throw red?
Los Angeles, why is the water that jets drop on firefighting red?

The fires that have engulfed Los Angeles for several days are bringing dramatic stories and images (some of them fake) from across the ocean.

Many have become curious after seeing the images, even spectacular, where firefighting aircraft drop a strangely colored substance onto the ground.

But why is the water that jets throw out red (or pink, depending on the photos)?

The simple answer is this: It is not water.

American firefighters, in addition to water taken from the ocean, also use artificial chemical substances and compounds to control forest fires.

These substances have various beneficial uses, as they help reduce the amount of combustible material within a fire and prevent flames from spreading further.

Things that water alone cannot provide.

The product is called Phos-Chek, manufactured by the company Perimeter Solutions and used primarily in the United States.

It is available in both powder and concentrated liquid form.

It contains several ingredients, including phosphate salts, such as ammonium phosphate, which are intended to interrupt the burning process of plant material.

Thickening agents added to the substance increase the viscosity of the product, improving adhesion to vegetation and reducing spreading during application.

However, all of its ingredients are not known, because they are protected by an industrial secret that does not allow the chemical formula to be revealed.

But why is it red?

The red color is added for a very simple reason.

It helps identify areas that have been treated, making them immediately visible from both the air and the ground.

In recent days, international agencies have shared many images of houses and swimming pools covered in "red rain."

Is Phos-Chek harmful?

Although Phos-Chek is used to extinguish or mitigate flames, its effects are not very healthy for the environment and animals.

The compound is authorized for use in the United States by the USDA Forest Service (US Department of Agriculture), but the agency itself warns against prolonged exposure to this chemical.

Excessive skin contact can cause irritation, while inhalation of the ingredient can cause respiratory problems, the USDA explains.

Scientific studies have also found that the ingredient can be dangerous to wildlife, especially fish like rainbow trout, which can be harmed by Phos-Chek if it ends up in rivers and streams.

Of course, these days, limiting the devastating fires in California is a priority, but the use of these substances is not good for areas covered by "red foam."
