AFR Formula:
| From: | To: |
The Accident Frequency Rate (AFR) is a key safety performance indicator that measures the number of recordable accidents per 100,000 hours worked. It's widely used in UK occupational health and safety to benchmark and monitor workplace safety performance.
The calculator uses the AFR formula:
Where:
Explanation: The formula standardizes accident rates across different organizations and time periods by calculating the rate per 100,000 hours worked.
Details: AFR is crucial for monitoring workplace safety, identifying trends, benchmarking against industry standards, and implementing effective safety measures to reduce workplace accidents.
Tips: Enter the number of recordable accidents and total hours worked. Both values must be valid (accidents ≥ 0, hours > 0).
Q1: What constitutes a recordable accident?
A: In the UK, recordable accidents typically include those resulting in death, major injuries, or injuries requiring more than 7 days off work, as defined by RIDDOR regulations.
Q2: What is a good AFR value?
A: Lower values indicate better safety performance. Industry benchmarks vary, but generally an AFR below 1.0 is considered good, though this varies by industry sector.
Q3: How does AFR differ from accident severity rate?
A: AFR measures how frequently accidents occur, while severity rate measures the consequences of accidents (typically days lost per 100,000 hours worked).
Q4: What time period should be used for calculation?
A: Typically calculated annually, but can be calculated for any period to monitor trends. Consistent time periods should be used for comparison.
Q5: Are there industry-specific AFR benchmarks?
A: Yes, different industries have different risk profiles. Construction and manufacturing typically have higher AFRs than office-based industries.
