Injury Rate Calculation

Injury Rate Calculator

This calculator helps you determine the injury rate within your organization or team. Understanding your injury rate is crucial for implementing effective safety measures, allocating resources for prevention, and demonstrating commitment to employee well-being. The most common metric is the Total Recordable Incident Rate (TRIR).

Understanding the Injury Rate

The Total Recordable Incident Rate (TRIR) is a widely used metric to measure the frequency of work-related injuries and illnesses that require more than basic first aid. It's standardized to 200,000 hours (which represents 100 employees working 40 hours a week for 50 weeks a year) to allow for comparison between organizations of different sizes.

The formula is:

TRIR = (Number of Recordable Incidents * 200,000) / Total Hours Worked

A lower TRIR indicates a safer workplace. Regularly tracking and calculating this rate helps in identifying trends, evaluating the effectiveness of safety programs, and making informed decisions to reduce workplace hazards.

Example: If an organization had 15 recordable incidents and logged 240,000 total hours worked in the past year, the calculation would be:

TRIR = (15 * 200,000) / 240,000 = 3,000,000 / 240,000 = 12.5

This means the organization has an injury rate of 12.5 per 200,000 hours worked.
