Oh yes, you are right, in my mother tongue safety and security are the same word. It is still embarrassing, I should have been more careful.
They are also kind-of the same word(s) in German (Sicherheit / Sicherung).
Do native German speakers draw much distinction between Sicherheit and Sicherung, and to the same degree that we do in English?
If no, I am curious how the differentiation in concepts developed in English developed and whether it is also present in other Germanic languages.
I'd say native speakers of German distinguish it but it depends on the context ... talking about computers, it's typically more about security, while when talking about construction sites, it's typically more about safety.
