This document outlines a paradigm shift in safety engineering, moving from reactive, incident-based methods to proactive, hazard-based approaches. It emphasizes understanding energy sources and their transfer mechanisms to prevent potential accidents in product safety engineering. By analyzing incidents and standardizing construction, the aim is to implement safeguards that not only mitigate risks but also enhance effectiveness in safety measures. Ultimately, this approach seeks to create a safer environment by preemptively addressing hazards.
