DART Rate Formula
The following formula is used to calculate a DART rate:
DR = RIdart *200,000 / EHW
- Where DR is the dart rate
- RIdart is the number of recorded injuries or illnesses that resulted in Days Away, Restricted, or Transferred
- EHW is the total number of employee hours worked.
To calculate the DART rate, divide the number of recorded injuries or illnesses that resulted in time off by the number of hours worked, then multiply by 200,000.
DART Rate Definition
What is a dart rate?
DART stands for days away, restricted, or transferred. A DART rate is the rate at which injuries occur that result in any one of those in DART.
In other words, the DART incidences per employee hours worked.
Example Problem
How to calculate DART Rate?
- First, determine the number of injuries that resulted in days away, restricted, or transferred.
For this example problem, the total number of injuries that occurred that resulted in DART was 200.
- Next, determine the number of employee hours worked.
For this example problem, there were a total of 300,000 employee hours worked.
- Finally, calculate the DART rate.
Using the formula above, the dart rate is calculated to be:
DR = RIdart *200,000 / EHW
DR = 200 *200,000 / 300,000
DR = 133.33 injuries per 200,000 hours
FAQ
What is the significance of the number 200,000 in the DART rate formula?
The number 200,000 in the DART rate formula is used as a standard benchmark for comparison. It represents the equivalent of 100 employees working full time for a year (40 hours per week for 50 weeks), allowing businesses of different sizes to compare their safety performance on an equal basis.
How can a company reduce its DART rate?
A company can reduce its DART rate by implementing comprehensive safety and health management systems, providing regular training to employees on safety practices, ensuring the use of appropriate personal protective equipment, and encouraging prompt reporting and investigation of all incidents. Regular audits and reviews of workplace practices and environments are also crucial.
Why is monitoring the DART rate important for businesses?
Monitoring the DART rate is important for businesses as it provides a clear indicator of the safety performance and effectiveness of health and safety programs within the workplace. A lower DART rate not only reflects a safer work environment but can also lead to reduced costs associated with workplace injuries and illnesses, improved employee morale, and enhanced reputation with clients and investors.
