KEY PERMFORMANCE INDICATORS OF OCCUPATIONAL HEALTH AND SAFETY MANGEMENT SYSTEM(OHSMS)
Key Performance Indicators (KPIs) of an Occupational Health and Safety Management System (OHSMS) help measure how effectively the system is being implemented, maintained, and improved. Below are common and meaningful KPIs aligned with ISO 45001 and industry best practices:
🔹 Lagging Indicators (Reactive - After Incident Occurs)
-
Lost Time Injury Frequency Rate (LTIFR)
= (Number of Lost Time Injuries × 1,000,000) / Total Hours Worked -
Total Recordable Incident Rate (TRIR)
= (Total Recordable Injuries × 200,000) / Total Hours Worked -
Severity Rate
= (Total Lost Days × 1,000,000) / Total Hours Worked -
Number of Fatalities
-
Medical Treatment Injuries (MTI)
Number of injuries requiring medical treatment (not just first aid) -
First Aid Cases (FAC)
Count of injuries treated with first aid
