How to Calculate OSHA DART Rate

By April 7, 2020No Comments

OSHA rates and calculations are important to understand– and know how to calculate. They provide key performance indicators about workplace safety and how to lower workers comp costs. This article will explain what the DART rate is and how to calculate it.

What is DART Rate?

DART is an acronym that stands for: Days Away Restricted or Transferred. The DART rate is the number of recordable incidents (per 100 full-time employees) that results in:

  • One or more days away from work
  • One or more days of restricted work or job transfer

How to Calculate DART Rate

(Total # of DART Incidents X 200,000) / Total employee hours worked

Take the total number of DART incidents (recordable injuries or illnesses that resulted in Days Away, Restricted, or Transferred) and multiply by 200,000. Because this is a factor per 100 full-time employees, 200,000 is used because that represents 100 employees working 40 hours a week for a 50 week calendar year. Then, divide this number by the total number of hours worked by all employees.

Why is DART Rate Important? 

This is the information you’re sending to OSHA every year with your electronic submission. OSHA is using the DART rate as the key metric to determine who they’re going to target for inspections. If your DART rate is higher than your industry peers, you’re a prime candidate for an OSHA inspection.
