Lagging Indicators are retrospective safety metrics that measure past performance by tracking incidents, injuries, and other adverse events that have already occurred.
Common examples include total recordable injury frequency rate (TRIFR), lost time injury frequency rate (LTIFR), and the number of workplace accidents or fatalities.
These indicators provide valuable insights into historical safety trends and help organisations assess the effectiveness of their safety programs.
However, because they focus on past outcomes rather than proactive measures, they do not predict future incidents or identify potential risks before they materialise.
While essential for regulatory compliance and benchmarking, lagging indicators should be used alongside leading indicators to create a balanced, proactive safety strategy.
