If you are gloved and suited with a suitable respirator and goggles it is possible, though difficult to self decontaminate. A bucket full of 10% bleach solution for dipping your gloved hands (at least 10 minutes, not a quick swish)is probably the last step after a self-spray down with the same bleach solution from a re-purposed weed sprayer.
Note to self: But more bleach
I don't disagree, in theory, but how many Joes and Jills on the street are set up with the equipment and the self discipline to do that properly. I have the equipment, but greatly concerned about my ability to maintain a cool head with the patience to not take short cuts to succeed at that. Especially time after time.
