How to Measure Safety
It is hard to determine if you are safer if you are not measuring safety, and it is even harder to measure safety if you haven't yet defined what that is. How can we improve safety if we are unable to describe what safety is? There are numerous definitions of terms used when reporting undesirable events, including non-conformity, near miss, injury, accident, incident, grounding, and hazardous occurrence to name a few. If your goal is zero incidents, what does that mean: zero lost time injuries; zero spills outside of containment; zero customer service complaints; zero "not on time" arrivals or departures?
