I guess this reply is a little late but here it goes. We just got a new rotary saw and a new cutter's edge. Well they were put in a compartment with the old chain saw we have where we also kept the gas for that saw. Well now we have all the saws and all the gas including the gas for the fans and other power tools in the same compartment. I made a comment about storing the gas with composite blades but I could be talking to the wall for all the good it did. They checked with the dealer and he has never heard of such a thing so I'm ignored.
Why are those things banned? Those are "must have" tools and equipment of the fire service.
