San Diego is trying a unique approach to prevent wildfires: spraying brush with a citrus-based liquid that acts as both a fire inhibitor and a retardant.
"We're using it proactively," San Diego Fire-Rescue Deputy Chief Tony Tosca tells KNX News Chief Correspondent Charles Feldman, spraying the liquid before fires start.
Tosca explained that the liquid is also effective at extinguishing active fires. However, his department is currently focusing on treating evacuation corridors and spraying areas of concern after abatement to prevent future fire activity. This is being done through a grant-funded project with the San Diego River Conservancy.
He added that the liquid is much safer than conventional fire retardant. "The company, when we acquired the product through the grant, [assured us] that it's food-grade, citrus-based, and safe for fish and animals. It's been through multiple independent testing laboratories."
Compared to existing chemical retardants that are toxic to the environment, Tosca believes this is a potentially beneficial alternative.
Why aren't all fire departments using this seemingly ideal option?
Tosca emphasized his commitment to protecting San Diego's citizens. "It's my duty to protect this community in any way I can," he said, "and I'm willing to take the risk to try something new if it's safer and genuinely effective. I don't care about the risk of it not working or failing at an initiative. I want to do what's best to protect our citizens. That's sometimes difficult for people in positions of authority; they often avoid risk."
Even if the new approach doesn't ultimately succeed, Tosca believes trying it is worthwhile.
