Cal Fire Chief Ken Pimlott joins KCBS Radio reporter and guest In Depth host Jenna Lane for a discussion about his decades-long career in firefighting--a look back at how his career started, plus how firefighting has changed over the years. "You know, a number of things have changed. The basics of firefighting have not changed. How you put fires out, but the conditions have changed," he explained. "The risks to firefighters have really increased." And, as Pimlott pointed out to Lane, the risks to firefighters aren't just physical but mental as well. "And they may not occur overnight but they accumulate over years. And we're really seeing the effects of that and now when you have a fire season it really is year-round." As a result of back-to-back firefighters, deployments in some cases were back to back, Pimlott pointed out. Pimlott also addressed funding and investigations during his In Depth appearance. "The support for our fire prevention and law enforcement program is absolutely there. We have the resources to get that done, understanding that in the North Bay fires, we had over thirty fires we were investigation as part of this complex of fires. And it wasn't just in the North Bay." Investigators, said Pimlott, were essentially broken up into "teams" to address what were "complex" investigations. "It takes time and it takes painstaking work and it really is a process of eliminating what didn't start the fires, you can narrow these causes down." The cause of the Tubbs Fire, it should be noted--certainly one of the more remarkably deadly and destructive of the 2017 Wine County wildfires--has not yet been determined. "In some cases you can't determine a cause because it's just, you know, these are fire scenes that are burning haphazardly. I think we look at every fire as important, whether it's a small fire that burned a few acres or a fire like the Tubbs Fire that burned thousands of acres and took so many structures and lives. They're all important because the losses that are involved are the same no matter what scale you are at but it's also important to determine the cause so that we can help prevent fires in the future. If we identify certain causes then we can work to prevent that down the road. And, then the investigations themselves are used by others, district attorneys and insurance companies and other entities to look for their own needs."
