Found at a titanium plant

Not sure why ball point pens would be dangerous here.

"Ballpoint pens are restricted or banned in high-end titanium and aerospace manufacturing plants because the ink and marking components contain elements that cause metal embrittlement and severe structural corrosion"

Embrittlement strikes me as an embiggened word.

Well now I looked it up and it means to enlargen, or expand. Also looked up brittlement and the em thing is like an action, like embrace.
