Use our DART Rate Calculator to accurately measure your organization's occupational safety performance. Easily determine the frequency of recordable injuries and illnesses resulting in days away, restricted work, or job transfer (DART) per 100 full-time employees. This metric is essential for compliance and improving overall workplace safety.
Formula:
DART Rate = (Number of DART Incidents × 200,000) / Total Employee Hours Worked
- Number of DART Incidents: The total count of OSHA recordable injuries and illnesses that resulted in Days Away From Work, Restricted Work Activity, or Job Transfer within a specific period.
- 200,000: A constant representing 100 full-time employees working 40 hours per week for 50 weeks per year. This normalizes the rate to a standard base.
- Total Employee Hours Worked: The total number of hours all employees actually worked during the same specific period.
