Traditional safety programs struggle with serious injuries because they track injury frequency, and serious injuries come from a different, rarer set of exposures. A falling recordable rate mostly reflects fewer sprains, cuts and strains; it says little about the high-energy events, such as a pedestrian struck at a blind corner, that cause life-altering harm. Many programs also rely on lagging data and voluntary reports, which miss close calls nobody writes down. Programs that do address serious injuries identify potential serious-injury exposures directly, count precursor events, and verify that critical controls are in place.
The full guide is PSIF: preventing serious injuries and fatalities. The practical shift is from counting outcomes to counting exposure. For forklift operations, that means logging close calls by location and shift, classifying each by its potential severity rather than its actual outcome, and checking controls such as separation, speed limits and pre-operation inspections. The guide to precursor and outcome indicators explains how to build that measurement. Detection systems can supply close-call data that manual reporting misses, but the data only helps if someone reviews it and changes the layout or the process.
