The whole round up thing really relates to anyone who used a lot, on a regular basis. Still I would think that anyone with half a brain would used protection against any sort to chemical agent.

I used it once or twice many years ago. Wore long pants and sleeves, wellies, rubber gloves and a face mask. Never hurt to be cautious. That's why when I discovered the salt/vinegar combination, I didn't have to worry about any chemicals harmful to me.
