Meanwhile, new information is out about what caused the death of one Utah firefighter last month during California’s Mendocino Complex Fire.
According to a new report from the California Department of Forestry and Fire Protection, also known as CAL FIRE, he died after a very large air tanker flew overhead, dropping enough flame retardant over the area to uproot a 90-foot tree and break other similarly sized trees. Three others were injured by falling debris.
The air tanker was flying much closer to the treetops than it was supposed to, at about 100 feet above the treetops. According to the National Wildfire Coordinating Group, the minimum drop height for very large air tankers is 200 feet above vegetation.
Firefighters had been warned to move out of the area more than an hour before, but it isn’t clear they got the message.
The "Lessons Learned" section of the incident report suggests they may have been distracted.
"Fireline personnel have used their cell phones to video the aerial retardant drops. The focus on recording the retardant drops on video may distract firefighters," it reads. "This activity may impair their ability to recognize the hazards and take appropriate evasive action possibly reducing or eliminating injuries."
Forest Service research has found that between 2000 and 2012, large air tankers accounted for 17 percent of wildland firefighter fatalities.
