how dangerous are combat roach bait stations to humans?

[A B]

I took the sticker off a combat bait station, and I did wash my hands after I did that, but in general I would just like to know how poisonous these bait stations are to people, and what is the best way to handle them , I mean what precautions are essential, I did read the label sticker on the back, but I would like to know what is the proper way to handle them and is it dangerous to remove the sticker off the back of the combat roach station, I mean could it prove poisonous, what are the odds, if anyone can give me some information regarding this I would be greatly thankful..
