Across the organization, we have implemented the use of the United States Occupational Safety and Health Administration (OSHA) metrics to measure, evaluate, and compare our injury statistics.

The Recordable Incident Rate (RIR) is the industry standard for safety performance for the number of recorded injuries per 100 workers. This is a rear-view looking metric as it measures past performance and includes injuries which require medical attention. The recorded injuries range in severity from minor to severe.

In addition to the RIR, we review Lost-Time Injury Rates (LTIR) and Critical Injury Rate (CIR) as key safety metrics to provide better context to the type and severity of injuries.


Lost-Time Injury Rates (LTIR) measure the number of injuries where employees have “lost-time” or have missed their regularly scheduled shifts due to the workplace-related injury. All lost-time injuries are Recordable Injuries – therefore, the LTIR is a sub-set of the RIR, indicating the employee could not return to work the next day. 35 per cent of Recordable injuries are lost-time injuries (0.7 LTIR).


Stemming from a recent focus on Serious Injuries and Fatalities (SIFs), JDI adopted a Critical Injury Rate (CIR) of its own, using the Critical Injury definition from the Ontario Ministry of Labour as a guideline. The CIR provides an indication of the severity of the incident. Compared to Recordable Incidents, these injuries are more severe, and include concussions, fractures, and deep lacerations. Similarly, all critical injuries are Recordable Incidents. Tracking the CIR as a metric has helped the organization to focus on risk management and to identify areas of highrisk potential and severity to cause significant injury. Our attention has shifted to ensuring action plans are initiated to prevent highseverity and critical injuries.
