DART Rate, Transparent Calculation (2024)
What is the DART rate formula?
DART (Days Away, Restricted, or Transferred) is computed by OSHA as incidents × 200,000 ÷ hours worked. The 200,000-hour denominator equals roughly 100 full-time workers, which lets establishments of very different sizes be compared directly.
1 DART incidents × 200,000 ÷ 1,380,609 hours worked = 0.14 DART
Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping
