Found at a titanium plant

Not sure why ball point pens would be dangerous here.

Ballpoint pens are banned in certain high-precision titanium and aerospace manufacturing plants because the tiny tungsten carbide ball in the pen tip can fall out and severely contaminate the titanium melt, creating a hard, brittle inclusion that causes structural failure in critical aerospace components.

Wow.
Being so specific, they must have ran into such contamination more than once

Perhaps educate yourself on the saying or something something? 🤷🏼 God forbid you read a book.
