A new fire retardant, PHOS-CHECK Fortify, was approved by the USDA Forest Service with the unique selling point that after applied it's effective for months. I'm assuming that given the previous version had PFAs and the Environmental Fate section of this MSDS is blank that we'll find out in 50 years this was a terrible idea.
I guess I'm mostly concerned that preventative applications of fire retardant lets fuel build up over the years, creating potentially worse fires
