1. What is the DART Rate?

The DART (Days Away, Restricted, or Transferred) rate is a safety metric used 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 DART Rate formula:

Where:

• Incidents involving days away — Number of recordable incidents
• Total hours worked — Sum of all employee work hours
• 200,000 — Base for 100 full-time workers (40 hrs/week × 50 weeks/year × 100 workers)

Explanation: The rate standardizes incident reporting across organizations of different sizes by using 200,000 hours as a benchmark.

3. Importance of DART Rate Calculation

Details: The DART rate helps organizations track safety performance, identify trends, and compare safety records with industry benchmarks. It's often required by OSHA and other regulatory bodies.

4. Using the Calculator

Tips: Enter the number of recordable incidents 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 rates are 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 (Total Recordable Incident Rate) 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 calculated for any period (quarterly, monthly) for trend analysis.

Q4: Are there limitations to DART rate?
A: It doesn't account for incident severity and can be skewed by a few serious incidents in small workforces.

Q5: How is 200,000 hours derived?
A: It represents 100 employees working 40 hours/week for 50 weeks/year (allowing for 2 weeks vacation).
