Understanding DART Rate

DART (Days Away, Restricted, or Transferred) rate measures workplace injuries and illnesses that result in employees missing work, being assigned restricted duties, or being transferred to different jobs. It's a key OSHA metric for assessing workplace safety.

  • • Broken bones requiring recovery
  • • Surgery from workplace injury
  • • Severe back injury

Restricted Work Activity

Employee works but can't perform all normal job duties.

  • • Lifting restrictions
  • • Limited hours
  • • Light duty assignments

Job Transfer

Frequently Asked Questions

What is DART rate and how is it calculated?▼
DART (Days Away, Restricted, or Transferred) rate measures workplace injuries resulting in employees missing work, being assigned restricted duties, or being transferred. It is calculated as (Number of DART cases x 200,000) / Total hours worked by all employees.
What is a good DART rate?▼
A good DART rate varies by industry. For general industry, rates below 1.5 are considered excellent. Construction typically averages 1.5-2.5, while healthcare averages 2.0-4.0. Compare your rate to your specific industry average from the Bureau of Labor Statistics.
How does DART rate differ from TRIR?▼
TRIR (Total Recordable Incident Rate) includes ALL recordable injuries and illnesses, while DART only counts cases resulting in days away, restrictions, or transfers. DART is always equal to or lower than TRIR since it is a subset of total recordable cases.
Why does OSHA use 200,000 as the multiplier?▼
The 200,000 figure represents 100 full-time equivalent employees working 40 hours per week for 50 weeks (100 x 40 x 50 = 200,000 hours). This standardization allows fair comparison between companies of different sizes and across industries.
How can a company reduce its DART rate?▼
Effective strategies include implementing comprehensive safety training programs, conducting regular workplace hazard assessments, investing in ergonomic equipment, establishing a strong safety culture, performing root cause analysis on incidents, and maintaining an active near-miss reporting system.
What is the Experience Modification Rate (EMR)?▼
EMR compares your company's workers compensation claims history to the industry average. An EMR of 1.0 is average; below 1.0 indicates better than average safety performance and results in lower insurance premiums, while above 1.0 means higher premiums due to more claims.
