DART measures serious workplace injuries — those causing days away from work, restricted duties, or job transfers. OSHA requires employers to record work-related injuries on Form 300 (Log of Work-Related Injuries). DART includes only severe cases: days away, restricted work, or job transfer. DART Rate = (Number of DART cases × 200,000) ÷ Total hours worked.

What is the DART Rate?
The DART rate measures serious workplace injuries — those causing days away from work, restricted duties, or job transfers. OSHA uses DART to target inspections: rates above your industry average trigger scrutiny. The national average is 1.5, but construction averages 2.5 and healthcare 4.0. This calculator computes your DART rate per 200,000 work hours.
📋 Key Takeaways
- • DART = (Cases × 200,000) ÷ Total hours — standard OSHA formula
- • National avg 1.5; construction 2.5; healthcare 4.0
- • Above industry avg = higher OSHA inspection likelihood
- • Avg cost per DART case: ~$15,000 (NSC data)
📖 OSHA Recordkeeping
Only recordable incidents that result in days away, restricted work, or job transfer count toward DART. Log injuries on OSHA Form 300. First-aid-only cases do not count. Accurate recordkeeping is required — underreporting can lead to penalties.
DART vs TRIR
DART includes only severe cases (days away, restricted, transferred). TRIR includes ALL OSHA recordable cases — medical treatment beyond first aid. DART is a subset of TRIR. A high TRIR with lower DART means most incidents are minor.
📐 How to Calculate
DART Rate = (DART cases × 200,000) ÷ Total hours worked
Example: 8 cases, 800,000 hrs → (8 × 200,000) ÷ 800,000 = 2.0

❓ Frequently Asked Questions
What is the DART rate (Days Away Restricted Transferred)?
DART measures serious workplace injuries — those causing days away from work, restricted duties, or job transfers. OSHA uses DART to target inspections: rates above your industry average trigger scrutiny. Formula: (DART cases × 200,000) ÷ Total hours worked. The national average is 1.5; construction averages 2.5, healthcare 4.0.
How does OSHA recordkeeping affect DART?
OSHA requires employers to record work-related injuries on Form 300 (Log of Work-Related Injuries). Only recordable incidents that result in days away, restricted work, or transfer count toward DART. First-aid-only cases and fatalities are handled separately. Accurate recordkeeping is essential — underreporting can lead to penalties.
What is the difference between DART and TRIR?
DART includes only severe cases: days away, restricted work, or job transfer. TRIR (Total Recordable Incident Rate) includes ALL OSHA recordable cases — including medical treatment beyond first aid. DART is a subset of TRIR. A company can have a high TRIR but lower DART if most incidents are minor.
How do I calculate my DART rate?
DART Rate = (Number of DART cases × 200,000) ÷ Total hours worked. Example: 8 DART cases, 800,000 hours → (8 × 200,000) ÷ 800,000 = 2.0. The 200,000 factor represents 100 full-time employees working 2,000 hours/year, standardizing rates across company sizes.
What are industry benchmarks for DART rate?
National average: 1.5. Construction: 2.5. Healthcare: 4.0. Manufacturing: 2.8. Professional services: 0.7. Oil & gas and agriculture typically run higher (4–6+). Compare your rate to your industry — below average is good; above triggers OSHA attention.
How can I reduce my DART rate?
Implement safety training, hazard assessments, return-to-work programs, and ergonomic improvements. Invest in PPE, safety committees, and near-miss reporting. OSHA and NIOSH offer free resources. Each DART case costs ~$15,000 on average — prevention pays.
