No poison is safe. It should be handled like it is dangerous and cleaned off of you if it gets on you. I just read the warnings on the bottle I have and it says to wear protective clothing mist mask and goggles. Says it is harmful to people and animals when spraying and wet. It also says to immediately remove clothing after use.
I do not agree with a billion dollar judgement against the company that makes it. Monsanto is not responsible for people misusing their product just like Remington isn't responsible for people shooting someone with their rifles. And Ford wouldn't be responsible if someone drove a ford through a crowd.
