DART Rate Calculator

Calculate your OSHA Days Away, Restricted, or Transferred incident rate for workplace safety reporting.

DART Cases (Year)

Incidents resulting in days away, restrictions, or transfers

Total Hours Worked (Year)

Number of Employees

Total Recordable Cases

All OSHA recordable incidents

OSHA Formula:
DART Rate = (DART Cases × 200,000) / Total Hours Worked
TRIR = (Total Recordable Cases × 200,000) / Total Hours Worked
200,000 = 100 employees × 2,000 hrs/yr

What is the DART Rate?

The DART rate measures workplace injuries and illnesses that result in days away from work, job restrictions, or job transfers. It's a key safety metric required by OSHA for many industries.
