Aerial tankers have coated Los Angeles-area homes, vehicles and landscapes in pink fire retardant to slow wildfire spread, though questions about environmental impact persist.
Nadine Yousif reports for BBC.
In short:
- Firefighters are using Phos-Chek, a chemical fire retardant, to control wildfires across southern California.
- The product, consisting mostly of water, fertilizer salts and coloring agents, is sprayed to slow fires by coating vegetation and depriving flames of oxygen.
- Environmental concerns have led to lawsuits, with critics citing potential harm to aquatic life and wildlife habitats.
Key quote:
“The longer the retardant dries, the more difficult it is to remove completely.”
— Perimeter, the maker of Phos-Chek
Why this matters:
The increasing use of fire retardants raises concerns about balancing wildfire containment with environmental protection. As wildfires intensify due to climate change, communities and policymakers must consider potential trade-offs between safety and ecological impacts.
