I don't understand what you are suggesting Butcher as I have never heard of methonal being a problem to work with.
I mean the chemical is everywhere if there is an exposure issue it should be known.
You can buy gallons of it at any local hardware store, it is used as a camp cooking fuel, RV anti freeze, windshield washer fluid and so on.
It is also a fuel for your car, even more so if you have a drag racer
