it is in many places but care is still needed. for an example I spilt some on my side (I say some but It was from around my waist down to my thigh) I was using it it clean powder coating off a comercial lawn mower frame. It was early so I didnt leave work I decided it was no big deal two hours later I could not bear the pain any longer (it hurt that bad) so I told my boss and left. turns out it had burned me down my side and I had a scar there for a good year or two because of it.
that said... its really not that big of a deal I was stupid and paid the price but as I said earlier just be smart and you will be fine.
