What is Accident Frequency Rate?

The accident frequency rate is a measure used to evaluate the number of workplace accidents relative to the total hours worked by employees. It is typically expressed as the number of accidents per 200,000 hours worked, providing a standardized way to compare safety performance across different organizations or time periods.

Example Calculation

Let's assume the following values:

Using the formula to calculate the Accident Frequency Rate:

\[ AF = \frac{5 \times 200,000}{1,000,000} = \frac{1,000,000}{1,000,000} = 1 \text{ accident per 200,000 hours worked} \]

The Accident Frequency Rate is 1 accident per 200,000 hours worked.
