1. What is Accident Frequency Rate?

The Accident Frequency Rate (AFR) is a key safety performance indicator that measures the number of accidents per million hours worked. It provides a standardized way to compare safety performance across different organizations and time periods.

2. How Does the Calculator Work?

The calculator uses the AFR formula:

Where:

• \( A \) — Number of accidents
• \( H \) — Total hours worked
• \( 10^6 \) — Scaling factor to express rate per million hours

Explanation: The formula calculates how many accidents occur for every million hours worked, allowing for meaningful comparisons regardless of organization size.

3. Importance of AFR Calculation

Details: AFR is crucial for monitoring workplace safety, identifying trends, benchmarking performance, and implementing effective safety measures to reduce workplace accidents.

4. Using the Calculator

Tips: Enter the total number of accidents and total hours worked. Both values must be valid (accidents ≥ 0, hours > 0).

5. Frequently Asked Questions (FAQ)

Q1: What constitutes an "accident" for AFR calculation?
A: Typically, recordable accidents that result in injury, illness, or fatality requiring medical treatment beyond first aid.

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.

Q3: How often should AFR be calculated?
A: Typically calculated monthly, quarterly, and annually to track trends and measure the effectiveness of safety programs.

Q4: Are there limitations to AFR?
A: AFR doesn't account for accident severity. It should be used alongside other metrics like Severity Rate for comprehensive safety analysis.

Q5: What industries use AFR?
A: AFR is widely used in construction, manufacturing, mining, oil and gas, and other industries with significant safety concerns.
