Which term measures the days lost per million manhours worked?

• A. Accident Severity Rate
• B. Accident Frequency Rate
• C. Days Lost Rate
• D. Lost-Time Rate

Answer: (A)

Measuring the impact of injuries over work time is the idea here. The term that expresses days lost per million hours worked is the accident severity rate. It accounts for how many workdays are lost due to injuries and relates that to the total hours worked, scaled to a million hours, so you can compare across different-sized operations. In essence, ASR = (total days lost due to injuries) / (total hours worked) × 1,000,000. This is different from the accident frequency rate, which looks at how often accidents occur (a count per million hours) rather than how severe they are in terms of days lost. The other terms are less standard for this specific metric of days lost per million hours.
