DART (Days Away, Restricted, or Transferred Rate)
A safety metric measuring the number of injuries/illnesses resulting in days away from work, restricted duty, or job transfer per 100 full-time employees.
Key Facts
- Formula: (DART cases × 200,000) ÷ Total hours worked
- Subset of TRIR — only cases with days away, restriction, or transfer
- Considered a more severe indicator than TRIR
- Effective RTW programs significantly reduce DART rates
DART rate is calculated as: (Number of DART cases × 200,000) ÷ (Total hours worked). DART cases are a subset of OSHA recordable incidents — only those resulting in days away from work, job restriction, or transfer to another job. DART is considered a more severe indicator than TRIR because it excludes cases requiring only medical treatment beyond first aid. Insurance carriers and clients often use DART rates to assess workplace severity. Effective return-to-work programs and early intervention can significantly reduce DART rates.
Safety Performance Metrics Compared
Key workplace safety metrics used by employers, OSHA, and insurance carriers.
| Type | Formula Basis | What It Measures | Used By | Good Benchmark |
|---|---|---|---|---|
| TRIR | (Incidents × 200K) ÷ Hours | All recordable incidents | OSHA, clients | < 3.0 (construction) |
| DART | (DART cases × 200K) ÷ Hours | Severe cases (days away/restricted) | Insurance, clients | Below industry avg |
| EMR | 3-yr claims vs expected | Claims experience vs average | Insurance carriers | < 1.0 |
| CSA Score | Inspection/crash/violation data | Carrier safety across 7 BASICs | FMCSA | Below intervention threshold |
