Personnel Safety Metrics / Personal Safety Metrics (Management/Incident Investigation/metrics/Personal Safety Metrics)

Personal safety metrics, like process safety metrics, include leading and lagging indicators. Lagging indicators refer to injury, fatality rates, days away from work (DAFW), total recordable injury rate (TRIR), while leading indicators may include frequency or timeline of audits and training. Personal safety metrics may be defined as a means to track requirements and goals by measuring performance, activity, status in an effort to analyze critical information based on the trends, both improvements and degradations.

“Personal safety Metrics are important to track low-consequence, high-probability incidents (such as slips, trips and falls), but are not a good indicator of process safety performance”
