What is Injury Rate?

An injury rate is defined as the rate at which employees get injured on a job per 200,000 hours worked. Injury rate and incident rate are often used interchangeably, but in some cases, companies like to keep these separate since incident rates include illnesses and injury rates may not. This allows a company to distinguish between injury and illness.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ IR = \left( \frac{5 \times 200,000}{400000} \right) = 2.5 \]

The Injury Rate is 2.5.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ IR = \left( \frac{3 \times 200,000}{150000} \right) = 4 \]

The Injury Rate is 4.
