Trend analysis for Diamond Jo Casino
Between 2017 and 2024, Diamond Jo Casino's Total Case Rate improved from 2.4 to 2.1 recordable injuries per 100 full-time workers, a 12% decrease across 7 years of OSHA reporting.
The safest year on record was 2023, at a TCR of 1.1, while 2020 saw the highest rate, at 4.6, a spread of 3.5 points between the best and worst reporting years. That's a wide swing relative to the establishment's overall rate, worth checking the year-by-year table below for whether a single severe year is driving the average, rather than a sustained trend.
Summed across those 7 reporting years, Diamond Jo Casino recorded 44 total injuries and illnesses and 1 fatality. Readers comparing establishments should weigh the 7-year trend above alongside establishment size, since a larger workforce naturally accumulates more raw incidents even at a lower per-100-worker rate.

DART Rate, Transparent Calculation (2024)
What is the DART rate formula?
DART (Days Away, Restricted, or Transferred) is computed by OSHA as incidents × 200,000 ÷ hours worked. The 200,000-hour denominator equals roughly 100 full-time workers, which lets establishments of very different sizes be compared directly.
4 DART incidents × 200,000 ÷ 569,218 hours worked = 1.41 DART
Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping
