Many of the human-caused fires originate in the same hotspots such as mountain passes and highway sections. Unfortunately, there is no environmentally-safe prophylactic fire-retarding treatment available for use in fire prevention. However, Stanford researchers have developed an environmentally-benign cellulose-based hydrogel that can retain polyphosphate fire retardants on target fuels for up to several months following application with common spraying equipment. In collaboration with Cal Fire, the Desert Research Institute, and the U.S. Forest Service, this project will pilot, optimize and validate the technology.
