1. What is the DART Rate?

The DART (Days Away, Restricted, or Transferred) rate is an OSHA metric that measures workplace safety. It calculates the number of recordable incidents per 200,000 employee 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:

• Number of DART Cases — Total recordable incidents that resulted in days away, restricted work, or transfer
• Total Hours Worked — Sum of all hours worked by all employees during the period
• 200,000 — Base for 100 full-time workers (50 weeks × 40 hours × 100 workers)

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

3. Importance of DART Rate

Details: The DART rate helps organizations track safety performance, identify problem areas, and measure the effectiveness of safety programs. It's a key OSHA metric for workplace safety evaluation.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What's considered a good DART rate?
A: Lower is better. Industry averages vary, but rates below 2.0 are generally considered good for most industries.

Q2: How does DART differ from TRIR?
A: TRIR includes all recordable incidents, while DART only includes those resulting in days away, restricted work, or transfer.

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 (full-time, part-time, temporary) and actual hours worked (excluding vacation, sick leave, etc.).

Q5: How can we reduce our DART rate?
A: Focus on hazard identification/control, safety training, near-miss reporting, and strong safety leadership.
