The TRIFR (Total Recordable Injury Frequency Rate) is a safety metric that quantifies the frequency of recordable injuries within an organization. To calculate TRIFR, follow this straightforward formula:
TRIFR = ((LTI+MTI+RWI)×1,000,000)/Hours Worked
Where:
LTI: Lost Time Injuries
MTI: Medical Treatment Injuries
RWI: Other injuries requiring medical treatment by a professional
The result represents the total recordable injury frequency rate per million hours worked.
The TRIFR (Total Recordable Injury Frequency Rate) encompasses fatalities, lost time injuries (LTIs), substitute work, and other injuries requiring treatment by a medical professional.
TRIFR (Total Recordable Injury Frequency Rate) encompasses all injury types, including fatalities, lost time injuries, alternate work, and other injuries requiring medical treatment. It calculates the number of these injuries per million hours worked.
LTIFR (Lost Time Injury Frequency Rate), in contrast, focuses solely on fatalities and lost time injuries. It does not consider other injury types. The LTIFR calculates the number of fatalities and lost time injuries per million employees.
The Total Recordable Injury Frequency Rate (TRIFR) is a crucial safety metric that organizations use to measure and monitor their safety performance. It provides a standardized rate by considering the total number of recordable incidents and the hours worked. TRIFR aids in assessing safety programs, benchmarking against industry peers, and fostering transparent communication.
TRIFR is comprehensive because it includes all injuries requiring medical treatment from a medical professional, such as fatalities, lost time injuries (LTIs), and other injuries. By combining various incidents and safety outcomes, TRIFR offers a holistic view of an organization’s safety performance.
To calculate TRIFR, you’ll need the following inputs:
Total Work Hours: Sum of all hours worked by employees during a specific period (e.g., a month or a year).
Total Recordable Injuries: The number of injuries that required medical treatment beyond first aid, restricted work, or resulted in lost workdays.
Number of Lost Workdays: The total days lost due to work-related injuries. This includes both partial and full workdays.
Number of Restricted Workdays: The total days where employees had to perform modified duties due to work-related injuries.
Number of Medical Treatment Cases: Instances where employees received medical treatment beyond basic first aid.
Remember to collect accurate data and ensure consistency in reporting to calculate TRIFR effectively.
