Human Factors Performance Indicators

The measurement of safety performance using retrospective (lagging) indicators such as incident and accident rates is a long-standing requirement in most developed economies. Similarly, the use of leading indicators to monitor the precursors to individual accidents (so-called 'slips, trips and falls') is usual in many industries, particularly where behavioural safety systems have been implemented. The adoption and use of leading and lagging indicators (performance indicators (PIs)) to monitor and manage major accident hazards safety performance is, however, still a developing area. In general, the literature that does exist in this area covers technical aspects of process safety, but not human factors.
