Total Recordable Incident Rate in Manufacturing KPIs
Safety is paramount in any manufacturing process, and one key safety Performance Indicator (KPI) is the Total Recordable Incident Rate (TRIR).
Overview
In the context of manufacturing, the Total Recordable Incident Rate measures the number of workplace injuries per 200,000 hours worked. It includes all incidents that resulted in lost time, job transfers, restricted work, or medical treatment beyond first aid.
This KPI is essential because it provides a comprehensive view of safety incidents, including not only severe injuries but also minor ones that can often be overlooked. A lower TRIR signifies fewer safety incidents and a safer working environment, implying effective safety protocols.
Calculation
To calculate the Total Recordable Incident Rate, you need to know the number of recordable incidents and the total number of hours worked by all employees.
The formula for Total Recordable Incident Rate is:
Total Recordable Incident Rate = (Number of Recordable Incidents / Total Hours Worked by All Employees) * 200,000
The Number of Recordable Incidents represents the total count of workplace injuries that resulted in either lost time, job transfers, restricted work, or medical treatment beyond first aid during a defined period.
Total Hours Worked by All Employees is the cumulative number of hours all employees have worked during the same period.
The number 200,000 is used to normalize the rate per 100 full-time workers working 40 hours per week, 50 weeks per year, making the rate easier to interpret.
Tracking and aiming to lower the TRIR can help manufacturing operations proactively manage potential risks and continually optimize their safety protocols. Nonetheless, this metric should be
