What is an OSHA Days Away, Restricted, or Transferred (DART) Rate?

Posted by admin on March 12, 2019
   

The Days Away, Restricted, or Transferred (DART) Rate is designed to track any OSHA recordable workplace injury or illness that results in time away from work, restricted job roles, or an employee's permanent transfer to a new position. OSHA uses the DART rate to monitor high-risk industries, and they also allow EHS managers to measure the business impact of recordable incidents over time.

How to calculate your company's DART rate?

The DART rate is calculated using the following formula:

  • (Number of OSHA Recordable injuries and illnesses that resulted in Days Away; Restricted; Transferred X 200,000) / Employee hours worked = Days Away Restricted Transferred (DART) Rate

To break this formula down, employers multiply the number of incidents that caused an employee to cease working in their normal capacity by 200,000.  This 200,000 represents 100 employees working 40 hours a week for 50 weeks during a calendar year. Then, this number is divided by the total number of hours a company's employees worked.

For example, say a company had lost-time incidents that occurred during a year. If the organization has around 1,000 employees that work 40 hours a week, this number may not be consequential or indicative of a greater problem. If, however, a smaller company only employing 10 or 15 people reports the same number of incidents, OSHA may be concerned that the company is failing to follow proper healthy and safety procedures.

OSHA also considers industry risk levels when examining DART rates. For example, if a logging company or intensive manufacturer has a relatively high DART rate, this may be attributed to the dangerous working environment. However, if a high rate comes from a low-risk retailer or manufacturer, this may be a sign that the organization needs to take serious steps to address this problem. 


What's the Difference between the DART rate and TCIR?

A DART Rate stands for "Days Away Restricted or Transferred" Rate and includes only those OSHA recordable injuries or illness that resulted in days away from work, restricted duty, or transfer of duties. 

The Total Case Incident Rate, also known as the TCIR and TRIR, is defined as the number of all work-related injuries per 100 full-time workers during a one year period.

Typically, your organization's DART rate will be lower than its TCIR. This is because only the more severe OSHA recordable injuries and illnesses are included in your DART rate.

How are incident rates used?

Incident rates serve as a benchmark that you can use to compare and evaluate your company's safety program against other organizations or your performance in past years. It's a good idea to keep an eye on these metrics as they play a key role in improving safety performance.  

As incident rates are used throughout many industries, the type of industry and nature of the work is taken into account when analyzing past data. Incident rates are lagging indicators. OSHA officials state that these statistics indicate past performance and aren't necessarily indicative of future incidents or procedures. For similar industries, OSHA may compare certain safety data of companies to others within the same business sector.

"Incident rates are used throughout many industries."

"Although OSHA could potentially use this data for enforcement action, unless incident rates are consistently high for a small company over a number of years, they will not normally target particular industries or companies for enforcement action," New Mexico Mutual, a provider of medical benefits for injured workers, explained in a report.

What is a good DART rate?

DART Rates differ from industry to industry; with certain industries having a significantly higher risk than others.  Many organizations compare themselves to other organizations with the same NAICS code to determine a good DART score. Overall, the United State Bureau of Labor Statistics (BLS) reports a DART of 1.5 cases per 100 full-time equivalent workers for private industry in 2017.
