I generally only handle 1/4 inch tape with mold and other crud and do that in my garage wearing a NIOSH certified respirator (cartridge type), but I make NO GUARANTEES that is safe. I'm still alive and my airways are doing better now that I'm out of LA and getting more sleep. Please be careful. None of this stuff is really good for you. Also be careful pulling apart a tape that needs baking (like 456) before you bake it as you can pull the mag coat off in some instances.
