What does the accident severity rate measure?

The accident severity rate is a measure that quantifies the impact of workplace accidents based on the number of days lost due to injuries in relation to the hours worked. Specifically, it is calculated as the number of lost workdays per million man-hours worked. This metric helps organizations understand the severity of injuries that occur, beyond just counting the number of injuries. By focusing on the days lost, it highlights how serious the accidents are and how they affect overall workforce productivity and health.

This approach is important because it offers insights into not only how often accidents occur but also their consequences, which is key for improving safety measures and reducing the future risk of severe injuries.
