In a groundbreaking effort to combat the devastating wildfires in California, authorities in Los Angeles have deployed hundreds of thousands of gallons of a new pink fire retardant. This chemical agent, primarily composed of ammonium phosphate and iron oxide, is designed to suppress flames effectively while minimizing environmental impact.
Since January 7, 2025, wildfires have wreaked havoc across the region, forcing thousands to evacuate and destroying over 12,000 structures. The rapid spread of these fires has been exacerbated by Santa Ana winds, making firefighting efforts increasingly challenging.
The California Department of Forestry and Fire Protection (CAL FIRE) has reported that the pink powder not only cools the burning vegetation but also creates a protective layer that slows combustion by removing oxygen from the flames. Despite its effectiveness, the use of this chemical has raised concerns regarding its safety for wildlife.
Daniel McCurry, a civil and environmental engineering professor at the University of Southern California, has conducted research that indicates the presence of heavy metals, such as chromium and cadmium, in some commonly used fire retardants. He emphasizes the need for further studies to assess the long-term impacts of these substances on the environment.
Perimeter, the company supplying the fire retardant, asserts that the formulations used in California have undergone rigorous testing to meet health and safety standards. The company also clarifies that the heavy metals identified in McCurry's research were from outdated formulations no longer in use.
As California continues to face the threat of wildfires, the use of advanced fire retardants is seen as crucial for protecting lives and property. Power companies in the Los Angeles area are also utilizing these agents to safeguard electrical poles and wires from fire damage. Edward Goldberg, a representative from Perimeter, stated, "Using fire retardants in wildland areas is the best way to save lives, protect communities, and keep fires small."
