1. What is DART Rate?

The DART (Days Away, Restricted, or Transferred) rate is a safety metric used by OSHA to measure workplace safety. It represents the number of recordable incidents per 200,000 work hours that result in days away from work, restricted work activity, or job transfer.

2. How Does the Calculator Work?

The calculator uses the OSHA DART Rate formula:

Where:

• DART cases — Number of OSHA recordable incidents resulting in days away, restricted work, or transfer
• 200,000 — Base for 100 full-time workers (working 40 hrs/week, 50 weeks/year)
• Hours worked — Total hours worked by all employees during the period

Explanation: The rate standardizes injury/illness data to compare safety performance across organizations of different sizes.

3. Importance of DART Rate

Details: DART Rate is a key OSHA metric for evaluating workplace safety programs. Lower rates indicate better safety performance. Many companies track this metric to benchmark safety improvements.

4. Using the Calculator

Tips: Enter the total number of DART cases and total hours worked by all employees during the measurement period. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's considered a good DART Rate?
A: Rates vary by industry. The average private industry rate is about 1.5. Compare to industry benchmarks for context.

Q2: How does DART differ from TRIR?
A: TRIR (Total Recordable Incident Rate) includes all recordable incidents, while DART only includes those resulting in days away/restricted/transferred.

Q3: What time period should be used?
A: Typically calculated annually, but can be used for any period (quarterly, monthly) for trend analysis.

Q4: Who should be included in hours worked?
A: Include all employees, including temporary and part-time workers. Exclude contractors.

Q5: How can I reduce my DART Rate?
A: Focus on hazard identification/elimination, safety training, proper PPE, and strong safety culture.
