The formula to calculate the Total Recorded Incident Rate (TRIR) is:
\[ TRIR = \frac{I \times 200,000}{HW} \]
Where:
TRIR is short for the total recorded incident rate and is a measure of the number of “incidents” per hours worked.
Let's assume the following values:
Using the formula:
\[ TRIR = \frac{5 \times 200,000}{500,000} = 2 \]
The Total Recorded Incident Rate ((TRIR)) is 2.
