Arizona State Forestry Officials say last year – 74% of Arizona’s wildfires were caused by humans. And with Wildfire season quickly approaching, Central Arizona Fire and Medical Fire Marshal Rick Chase wants residents to be very familiar with the campaign One Less Spark, One Less Wildfire. Chase says he’s seen wild fires started by residents mowing there grass to create defensible space when one of the blades strikes a rock and creates a spark. He also says fires have been started by grinding or working with metal and power tools as well as torches. Chase asks everyone to be aware of their actions and how they can avoid creating a spark that can ignite a wildfire.Residents are also urged to be prepared for an evacuation by following Ready,Set,Go and to sign up for Code Red through the County Sheriff’s website.
