Trir Calculator

The TRIR Safety Calculator enables users to calculate the Total Recordable Incident Rate (TRIR), Incident Frequency Rate, and Average Hours Between Incidents based on the number of OSHA recordable incidents, total hours worked, and desired timeframe.

How to Use the TRIR Safety Calculator

This step-by-step guide will help you to use the TRIR Safety Calculator effectively to calculate your Total Recordable Incident Rate (TRIR) and other related metrics. Follow the instructions below to ensure precise calculations.

Step 1: Enter the Number of OSHA Recordable Incidents

Begin by entering the total number of OSHA recordable incidents that occurred during the calculation period. This is a mandatory field.

  • Label: Number of OSHA Recordable Incidents
  • Placeholder: Enter number of recordable incidents
  • Restrictions: Must be a non-negative integer (minimum value is 0).

Step 2: Input the Total Hours Worked

Next, input the total number of hours worked by all employees during the period. Accurately recording this data is crucial as it directly impacts the TRIR calculation.

  • Label: Total Hours Worked
  • Placeholder: Enter total employee hours worked
  • Restrictions: Must be a non-negative integer (minimum value is 0).

Step 3: Select the Calculation Period

Select the time frame that the data covers. This selection is essential to determine the frequency of incidents over the selected period.

  • Label: Calculation Period
  • Options:
    • Monthly: One month period
    • Quarterly: Three months period
    • Annually: Twelve months period

Step 4: View the Calculation Results

After entering the required data and selecting the calculation period, the calculator will compute the following metrics:

  • Total Recordable Incident Rate (TRIR): This rate represents the number of recordable incidents per 200,000 hours worked. The result will be a number with two decimal points and will look like, for instance, “2.45 incidents per 200,000 hours worked.” The TRIR is calculated using the formula: (recordableIncidents * 200000) / totalHoursWorked.
  • Incident Frequency Rate: This metric indicates how often incidents occur within a year based on the provided data. It is calculated using the formula: (recordableIncidents / timeframe) * 12. The rate is formatted as a number with two decimal points, shown as “3.50 incidents per year.”
  • Average Hours Between Incidents: This figure shows the average number of hours worked between incidents. The result is rounded to a whole number and expressed as, for example, “4000 hours.” The calculation is based on: totalHoursWorked / (recordableIncidents == 0 ? 1 : recordableIncidents).

Using these steps, you can successfully operate the TRIR Safety Calculator to analyze workplace incident statistics efficiently. Make sure all input data is accurate to ensure reliable results.
