What is the German word for 'safety measure'?

The German term for 'safety measure' is "Vorsichtsmaßnahme." This word is composed of two parts: "Vorsicht," meaning 'caution' or 'care,' and "Maßnahme," which translates to 'measure' or 'action.' Therefore, "Vorsichtsmaßnahme" literally conveys the idea of a measure taken to ensure safety or precaution in various contexts, such as occupational safety, public health, or even in everyday practical situations.

In contrast, the other terms do not relate to safety measures. "Niet" refers to a type of fastener or rivet, "Flaschenzug" translates to 'pulley' or 'block and tackle,' and "Hohlwelle" means 'hollow shaft.' None of these words conveys the meaning related to safety measures, making "Vorsichtsmaßnahme" the precise and correct choice for describing safety precautions in German.
