Frequently Asked Questions
The accident frequency is calculated per 200,000 hours worked because it represents the average number of hours worked by 100 employees in one year. This helps standardize the accident frequency rate for better comparison across industries and organizations.
Calculating the accident frequency helps organizations track their workplace safety performance, identify trends, and implement effective safety measures to reduce accidents. It allows for comparison with industry benchmarks and aids in setting realistic safety goals.
Yes, accident frequency can be used to compare different industries, as it provides a standardized metric for evaluating workplace safety. However, it’s important to consider the nature of the work and the inherent risks associated with each industry when making comparisons.
Several factors can influence the accident frequency rate, including workplace safety culture, employee training and awareness, work environment, job complexity, adherence to safety regulations, and the use of personal protective equipment (PPE).
Organizations can lower their accident frequency rate by implementing a comprehensive safety program, providing regular safety training and education for employees, conducting safety audits, enforcing safety regulations, maintaining a clean and hazard-free work environment, and encouraging a strong safety culture among staff.
Enter the number of accidents and the employee hours worked into the Accident Frequency Calculator. The calculator will evaluate the Accident Frequency.
Accident Frequency Formula
The following two example problems outline the steps and information needed to calculate the Accident Frequency.
AF = A * 200,000 / HW
- Where AF is the Accident Frequency (accidents per 200,000 hours worked)
- #A is the number of accidents
- HW is the employee hours worked
To calculate the accident frequency rate, multiply the number of accidents by 200,000 then divide by the employee hours worked.
How to Calculate Accident Frequency?
The following example problems outline how to calculate Accident Frequency.
Example Problem #1:
- First, determine the number of accidents.
- The number of accidents is given as: 30.
- Next, determine the employee hours worked.
- The employee hours worked is provided as: 150,000.
- Finally, calculate the Accident Frequency using the equation above:
AF = #A * 200,000 / HW
The values provided above are inserted into the equation below and computed.
AF = 30 * 200,000 / 150,000 = 40 (accidents per 200,000 hours worked)
Example Problem #2:
For this problem, the variables required are provided below:
number of accidents = 50
employee hours worked = 400,000
Test your knowledge using the equation and check your answer with the calculator..
AF = #A * 200,000 / HW = ?
