DART Rate (Days Away, Restricted, or Transferred)

A metric measuring the rate of injuries and illnesses severe enough to result in days away from work, restricted duties, or job transfer per 200,000 hours worked.

DART Rate (Days Away, Restricted, or Transferred) is a term from U.S. workplace-safety regulation — typically a category in OSHA enforcement, a citation classification, or a worker-protection concept under the OSH Act. The definition here is the practical worker-facing meaning. Understanding DART Rate (Days Away, Restricted, or Transferred) is part of reading OSHA enforcement records defensibly. Citation classifications (serious, willful, repeat, other-than-serious, de minimis) carry meaningfully different implications for both employers and workers, and the worker-relevant interpretation often differs from the strict legal definition.

Each company page on OSHARecord surfaces DART Rate (Days Away, Restricted, or Transferred)-relevant data for that specific employer, so the general definition here translates into concrete enforcement-history detail on the per-employer pages workers actually use.

What It Means

The DART rate is calculated similarly to the TRIR but only counts incidents that resulted in at least one day away from work, one day of restricted work activity, or a job transfer. This makes DART a more focused measure of injury severity than the broader TRIR, since it excludes less severe recordable incidents such as those requiring only medical treatment beyond first aid. The formula is: (number of DART incidents x 200,000) / total hours worked. OSHA uses DART rates as part of its Site-Specific Targeting (SST) program to identify workplaces with elevated injury rates for programmed inspections. Employers whose DART rates exceed the national average for their industry are more likely to receive an OSHA inspection. Insurance underwriters and construction prequalification services also rely heavily on DART rates when assessing employer risk profiles. A high DART rate compared to industry average suggests that a workplace not only has injuries occurring but that those injuries are serious enough to keep workers off the job or limit their duties.
