According to safety standards, why are most accidents considered unavoidable?

Most accidents are considered unavoidable because they are inherently unpredictable. While precautions can be taken to minimize risks, there will always be a level of uncertainty associated with human activities and environmental factors. This unpredictability means that no matter how rigorous safety measures are, certain factors can lead to accidents despite best efforts.

For instance, an unexpected mechanical failure or an unforeseen hazard can arise, making it impossible to foresee and prevent every potential accident. The acknowledgment of this unpredictability underlies the rationale behind safety standards, which aim to reduce the probability and impact of accidents rather than eliminate them entirely.

It's important to note that while negligence, human error, and natural disasters can certainly contribute to accidents, these factors do not encompass all possible scenarios. Many accidents occur due to a web of unpredictable circumstances that make them ultimately unavoidable.
